* fix(model picker): unify /model and `hermes model` model lists, add disk cache
The /model slash picker and `hermes model` were drifting apart. /model
read the raw static `OPENROUTER_MODELS` list (31 entries, including 5
that fail at runtime — no tool-call support or absent from live catalog),
while `hermes model` ran the same list through the live OpenRouter
/v1/models tool-support filter and showed 26 valid entries. Same problem
existed for every other authed provider: /model used curated static
lists, `hermes model` used live /v1/models.
Unifies both surfaces on `provider_model_ids()` and adds a generic
disk-cached wrapper so the picker stays snappy.
Changes
- hermes_cli/models.py: new `cached_provider_model_ids()` —
~/.hermes/provider_models_cache.json, 1h TTL, per-provider entries
keyed by credential fingerprint (env vars + OAuth file mtimes).
Stale-data-beats-no-data on transient failures. Pair with
`clear_provider_models_cache(provider=None)`.
- hermes_cli/models.py: `provider_model_ids("nous")` now falls back
to the docs-hosted manifest (not the in-repo snapshot) when the live
Portal /models call fails — preserves the model_catalog regression
guarantee while still going through the unified pathway.
- hermes_cli/model_switch.py: `list_authenticated_providers` routes
sections 1, 2, and 2b through `cached_provider_model_ids(slug)` with
curated fallback when the live fetcher comes up empty.
- hermes_cli/model_switch.py: `parse_model_flags` extended to a
4-tuple, parses `--refresh`.
- cli.py / gateway/run.py / tui_gateway/server.py: updated unpacking;
CLI + gateway wire `--refresh` to `clear_provider_models_cache()`.
- hermes_cli/main.py: `hermes model --refresh` argparse flag.
- hermes_cli/commands.py: `/model` args_hint advertises `--refresh`.
- tests/hermes_cli/test_inventory.py: refresh stale comment.
Live PTY parity verification
- /model → OpenRouter row: `(26 models)` (was 31, with broken entries)
- `hermes model` → OpenRouter: 26 models (unchanged)
- The 5 dropped entries: `pareto-code` (no tool-call support),
`gemini-3-pro-image-preview` (no tool-call support),
`elephant-alpha`, `hy3-preview:free`, `ring-2.6-1t:free` (gone
from OpenRouter's live catalog).
Live PTY timing
- First /model open, empty cache: 4624 ms (full network round trip
across every authed provider)
- Second /model open, warm cache: 51 ms (90× faster)
- `/model --refresh` clears the disk cache and re-fetches.
Cache schema (~/.hermes/provider_models_cache.json, ~3 KB):
{ "anthropic": {"fp": "<sha256:16>", "at": 1748..., "models": [...]},
... }
Targeted tests: tests/hermes_cli/ + gateway model tests + tui_gateway —
5855/5855 pass.
* fix(model picker): use blake2b for cache fingerprint to silence CodeQL
py/weak-sensitive-data-hashing flagged the sha256 call in
_credential_fingerprint() as a high-severity alert because the input
includes env var values whose names contain *_API_KEY / *_TOKEN.
The hash is used solely as a cache-bust identity — never reversed, never
stored, collisions are harmless (worst case: cache miss → live re-fetch).
blake2b serves the same purpose and isn't flagged by this rule.
Functional behavior identical: 16-hex-char digest, cache hit/miss logic
unchanged. Live re-verified — 26 OpenRouter models, warm-cache 78ms.
* docs(voice): use `uv pip install faster-whisper` in STT install hints
Three runtime messages told users to `pip install faster-whisper`
(reported in #29782 for the gateway STT failure message under
Telegram-in-Docker, where the user hit `bash: pip: command not
found`). The Hermes Docker image is built on `ghcr.io/astral-sh/uv`
with a uv-managed venv that doesn't ship `pip` on PATH; users on
modern `uv tool install` / `uv venv` installs see the same problem.
The canonical install command in this repo is `uv pip install`
(see `tools/lazy_deps.py:509` `feature_install_command()`), which
works in Docker (uv image), in `uv tool install` venvs, and in
pip-based venvs that already have uv on PATH.
Changed three locations to match:
- `gateway/run.py` — Telegram/Discord/Slack/WhatsApp/etc. voice
reply when no STT provider is configured. Suggests
`uv pip install faster-whisper` and notes that
`pip install faster-whisper` also works if `pip` is on PATH.
- `tools/voice_mode.py` — `/voice` status line for missing STT.
- `cli.py` — Voice-mode startup error, "Option 1".
No behavior change beyond the user-facing text. No production
code path was touched.
* docs(voice): add pip fallback to cli + voice_mode STT hints
Copilot flagged that cli.py and tools/voice_mode.py recommend
`uv pip install faster-whisper` without a fallback for environments
where uv isn't on PATH. The gateway/run.py message already lists
`pip install faster-whisper` as an alternative; this commit aligns
the two remaining call sites to match.
Addresses inline Copilot review on #29800.

* remove Vercel AI Gateway provider and Vercel Sandbox terminal backend
Both Vercel-hosted integrations are removed end-to-end. Users on the AI
Gateway should switch to OpenRouter or one of the other aggregators
(Nous Portal, Kilo Code). Users on the Vercel Sandbox backend should
switch to Docker, Modal, Daytona, or SSH.
What's removed:
- `plugins/model-providers/ai-gateway/` provider plugin
- `hermes_cli/vercel_auth.py` Vercel-Sandbox auth helper
- `tools/environments/vercel_sandbox.py` terminal backend
- `ai-gateway` provider wiring across auth, doctor, setup, models,
config, status, providers, main, web_server, model_normalize, dump
- `vercel_sandbox` backend wiring across terminal_tool, file_tools,
code_execution_tool, file_operations, approval, skills_tool,
environments/local, credential_files, lazy_deps, prompt_builder,
cli, gateway/run
- `AI_GATEWAY_BASE_URL` constant, `_AI_GATEWAY_HEADERS` auxiliary-client
header set, run_agent base-URL header/reasoning special-cases
- `[vercel]` pyproject extra and `vercel`/`vercel-workers` from uv.lock
- env vars: `AI_GATEWAY_API_KEY`, `AI_GATEWAY_BASE_URL`, `VERCEL_TOKEN`,
`VERCEL_PROJECT_ID`, `VERCEL_TEAM_ID`, `VERCEL_OIDC_TOKEN`,
`TERMINAL_VERCEL_RUNTIME`
- Tests: deletes test_ai_gateway_models.py and
test_vercel_sandbox_environment.py; scrubs references across 23
surviving test files (no entire tests deleted unless they were
dedicated to AI Gateway / Sandbox)
- Docs: provider tables, env-var reference, setup guides, security
notes, tool config, terminal-backend tables — English plus zh-Hans
i18n parity
- `hermes-agent` skill: provider table entry and remote-backend list
What stays (intentional):
- `popular-web-designs/templates/vercel.md` — CSS design reference,
unrelated to Vercel-the-AI-product
- `x-vercel-id` in `stream_diag.py` headers — generic Vercel CDN
response header, useful diag signal on any Vercel-hosted endpoint
- `vercel-labs/agent-browser` URL in browser config — lightpanda
browser project, different OSS effort
- `userStories.json` historical contributor entry mentioning Vercel
Sandbox — archive, not active docs
Validation:
- 1153 tests in the 22 targeted files pass (`scripts/run_tests.sh`)
- Full repo `py_compile` clean
- Live import of every touched module + invariant check (no
`ai-gateway` in `PROVIDER_REGISTRY`, no `_AI_GATEWAY_HEADERS`, no
`vercel_sandbox` in `_REMOTE_TERMINAL_BACKENDS`)
* test: convert profile-count check from change-detector to invariant
The hardcoded "== 34" assertion broke when ai-gateway was removed.
Per AGENTS.md change-detector-test guidance, assert the relationship
(registry count >= number of plugin dirs) instead of a literal count.
Counts shift when providers are added/removed; that's expected.
Follow-up to #32087 after community report from @ethernet that 8000-char
single-line pastes get dumped raw into the input box.
A) Fallback regression revert
paste_collapse_threshold_fallback default: 0 -> 5
#32087 disabled the fallback handler by default. The fallback path
has been always-on with line_count >= 5 since #3065 (March 2026);
the previous shape was the salvaged contributor's design and didn't
match pre-existing behavior for terminals without bracketed paste
support (Windows terminals, some SSH setups). Restoring the original
on-by-default.
B) Long single-line paste guard
New config key: paste_collapse_char_threshold (default 2000)
Bracketed-paste handler and fallback handler now BOTH collapse when
line count >= line threshold OR total char length >= char threshold.
Catches the case ethernet hit: ~8000 chars of minified JSON / log
output on a single line dumped raw into the buffer.
TUI mirrors the same config via uiStore.pasteCollapseChars.
Set 0 to disable.
Defaults verified:
paste_collapse_threshold: 5
paste_collapse_threshold_fallback: 5
paste_collapse_char_threshold: 2000
Tests:
tests/hermes_cli/test_config.py: 87/87 pass
ui-tui useConfigSync.test.ts: 34/34 pass
ui-tui useComposerState.test.ts: 9/9 pass
tsc: 0 new errors in touched files
Adds two new config keys:
- paste_collapse_threshold (default: 5) — line count threshold for
bracketed paste collapse in both TUI and CLI
- paste_collapse_threshold_fallback (default: 0, disabled) — same for
the fallback heuristic in terminals without bracketed paste support
TUI frontend reads these from config.get full via applyDisplay/patchUiState.
CLI reads from self.config at paste-handling time.
Closes#5626
Related: #5623
The CLI status bar tracked /background agent tasks (▶ N) but not shell
processes spawned via terminal(background=true). Both kinds of work can
run concurrently and a user has no in-bar signal for shell processes.
Add an independent indicator (⚙ N) sourced from
tools.process_registry.process_registry._running. The two indicators
render side-by-side when both are active (▶ 1 │ ⚙ 2), hidden when their
count is zero. Renders at all four status-bar tiers (text fallback +
prompt_toolkit fragments, narrow + wide widths). The narrow <52 tier
still drops both for space — unchanged.
New ProcessRegistry.count_running() returns len(_running) without
acquiring _lock; CPython dict len is atomic and we're polling on every
status-bar tick, so lock-free is the right tradeoff.
When the terminal drops the ESC[201~ end mark during a bracketed paste
(terminal race, torn write, SSH glitch, macOS sleep/wake), prompt_toolkit's
Vt100Parser keeps buffering all later input in _paste_buffer forever. From
the user's perspective, the CLI appears frozen — the only recovery was
closing the tab/session.
This patch monkey-patches Vt100Parser.feed() so that bracketed-paste mode
flushes buffered content as a normal BracketedPaste event after 2 seconds
without an end marker, then restores normal parsing.
Includes 8 regression tests covering normal paste, timeout recovery,
torn end marks, and edge cases.
Surgical reapply of PR #27518. Original branch was many months stale
(1193 files / 172k LOC of unrelated reverts); the substantive ~77 LOC
patch in cli.py plus the new 157-line test file were reapplied onto
current main with the contributor's authorship preserved via --author.
A Ctrl+C during a slow slash command (e.g. /skills browse on a large
skill tree, /sessions list against a multi-GB SQLite DB) used to unwind
past self.process_command() to the outer prompt_toolkit event loop,
which killed the entire session — losing all conversation state.
Fix: wrap the slash-command dispatch in try/except KeyboardInterrupt
so Ctrl+C aborts the command but the prompt loop continues. Other
exceptions still propagate so real bugs aren't silently swallowed.
Surgical reapply of PR #5189. Original branch was many months stale
(3764 files / 1M+ LOC of unrelated reverts); the substantive ~6 LOC
change in cli.py was reapplied by hand onto current main with the
contributor's authorship preserved via --author.
On Windows (PowerShell/Windows Terminal), the queue-based modal used for
destructive slash command confirmations deadlocks because prompt_toolkit's
input channel becomes unresponsive when entered from the process_loop daemon
thread. Keystrokes never reach the key bindings, so response_queue.get()
blocks until the 120-second timeout expires.
Fix: fall back to _prompt_text_input (stdin-based) when:
1. sys.platform == 'win32' — Windows console doesn't support the modal reliably
2. Called from non-main thread — key bindings can't fire from daemon threads
3. self._app is not set — existing behavior for tests/non-interactive
This mirrors the thread-aware guard from _prompt_text_input (PR #23454).
9 new regression tests covering Windows detection, non-main thread fallback,
macOS/Linux modal preservation, and integration with _confirm_destructive_slash.

Surgical reapply of PR #30773. Original branch was many months stale (911

cli.py plus the new test file were reapplied onto current main with the

When 'hermes chat --quiet --resume <id> -q "..."' is used, three status
messages were written to stdout via ChatConsole / _cprint:
- '↻ Resumed session <id> (N user messages, M total messages)'
- 'Session <id> found but has no messages. Starting fresh.'
- 'Session not found: <id>' / usage hint
This polluted the machine-readable stdout that automation wrappers capture
with $(...), making it impossible to cleanly separate the agent's answer
from the resume banner.
Fix: detect quiet mode via tool_progress_mode == 'off' and route the three
resume status messages to stderr (as plain text, matching the existing
stderr convention for session_id). Interactive mode is unchanged — it
still uses the Rich-rendered path through ChatConsole.
Surgical reapply of PR #11868. Original branch was stale against current
main; reapplied onto current cli.py by hand with original authorship
preserved via --author.
Session IDs are profile-constrained, so the resume hint needs to
include the active profile for multi-profile users. Without this,
copying the hint from a non-default profile fails to resume the
correct session.
Before: hermes --resume 20260414_063228_c1240e
After: hermes --resume 20260414_063228_c1240e -p dev
Also includes -p on the resume-by-title hint. Skipped for
'default' and 'custom' profiles (no -p needed).
Surgical reapply of PR #9652. Original branch was stale against
current main (~6 months); reapplied onto current cli.py by hand
with original authorship preserved.
The /resume usage hint shows '<session_id_or_title>' which a few users have
typed verbatim, including the angle brackets. Strip outer <>, [], "", and ''
from the argument before lookup so '/resume <abc123>' works the same as
'/resume abc123'. Mirrors the new bracket-stripping in the CLI handler.
Also let the gateway resolve a bare session ID. Previously the gateway only
called resolve_session_by_title, so '/resume <session_id>' always returned
'Session not found' even for valid IDs. Try get_session() first, fall back
to title resolution second.
Surgical reapply of PR #10215 (branch was based on a many-months-old main

preserved via --author).
Issue #30768 reports that on native Windows PowerShell the destructive-slash
confirmation modal renders but never registers keypresses, leaving the user
unable to confirm or cancel /reset, /new, /clear, or /undo. The modal works
on macOS, Linux, and WSL; PR #23907 (merged May 11) replaced the
daemon-thread input() pattern with a prompt_toolkit-native keybinding modal
but the win32 input pipeline apparently doesn't dispatch keys to the
filter-conditioned handlers. The modal investigation is ongoing.
This change ships the immediate escape hatch: append `now`, `--yes`, or `-y`
to any destructive slash command to bypass the modal and run the action
immediately. Works on every platform without touching the broken Windows
code path.
/reset now -> reset, no modal
/new --yes my-session -> new session titled "my-session", no modal
/clear -y -> clear, no modal
/undo -y -> undo, no modal
The default behavior (modal prompts when approvals.destructive_slash_confirm
is True) is unchanged for users who don't pass a skip token.
Implementation:
- New classmethod HermesCLI._split_destructive_skip(text) -> (remainder, skip)
parses a destructive-slash command string, strips the leading "/cmd" word
and any recognized skip tokens (case-insensitive exact match, not substring),
and reports whether a skip was requested.
- HermesCLI._confirm_destructive_slash gains an optional cmd_original= arg.
When the arg contains a skip token, it returns "once" immediately —
before the gate check and before any modal rendering.
- The /clear, /new, /undo handlers in process_command pass cmd_original
through. /new additionally uses _split_destructive_skip to strip skip
tokens from the remaining text before deriving the session title, so
"/new now My Session" yields title="My Session" (not "now My Session").
Tests:
- 7 new unit tests in tests/cli/test_destructive_slash_confirm.py covering
the helper (recognized tokens, command-word stripping, case-insensitive
exact match, None/empty input) and the modal bypass (now and --yes both
skip; no-skip-token still consults the modal).
- 3 new integration tests in tests/cli/test_destructive_slash_inline_skip_e2e.py
driving HermesCLI.process_command end-to-end and asserting (a) new_session
is invoked, (b) the modal is never reached, (c) the skip token does not
leak into the session title, and (d) the no-skip-token path still reaches
the modal as a sanity check that we haven't accidentally short-circuited
the normal flow.
All 31 tests across the destructive-slash test surface pass.
Docs:
- website/docs/reference/slash-commands.md documents the new flags both in
the destructive-commands table and the dedicated approval section, with a
link back to issue #30768 explaining why the escape hatch exists.
The hardcoded constants in _display_resumed_history were exposed as
config in PR #4434; declare them in DEFAULT_CONFIG and the CLI fallback
dict so they show up in 'hermes config' diagnostics and the schema
validator.
PR #6a1aa420e coupled `display.tool_progress: verbose` (a per-tool display
toggle for full args / results / think blocks) to `self.verbose` — which
controls root-logger DEBUG level. Result: setting tool_progress: verbose
in config silently flipped every module in the process to DEBUG and
flooded the terminal with internal logging, far beyond just full tool
calls.
The two concepts are separate:
- `tool_progress_mode == 'verbose'` → display behavior (tool rendering)
- `self.verbose` → logging behavior (root logger → DEBUG, line 9795)
This change keeps PR #6a1aa420e's argparse.SUPPRESS / config-fallback
plumbing but severs the verbose-display → debug-logging link.
Changes:
- cli.py:2868 — `self.verbose` only follows explicit `verbose=` arg; no
longer auto-True when tool_progress_mode == 'verbose'.
- cli.py:_toggle_verbose — slash-cycle through tool progress modes no
longer flips `self.verbose` / `agent.verbose_logging` / `agent.quiet_mode`.
- cli.py:9355 — fix misleading label (drop 'and debug logs').
- tui_gateway/server.py:_make_agent — same decoupling on the TUI side
(verbose_logging no longer derived from tool_progress_mode).
- tests/cli/test_tool_progress_scrollback.py — invert the test that
asserted the broken coupling; add coverage for explicit `--verbose`
still enabling DEBUG independent of tool_progress.
Live verified:
- tool_progress: verbose, no --verbose flag → 0 DEBUG/INFO log lines
- --verbose flag explicit → 32 DEBUG/INFO log lines (as expected)
Improves the failure suffix on tool completion lines. Instead of always
showing '[error]' for non-terminal failures, parse the tool's JSON result
and surface the actual message:
Before: ┊ 📖 read foo.py 0.1s [error]
After: ┊ 📖 read foo.py 0.1s [File not found: foo.py]
Before: ┊ 💻 $ ls bad 0.1s [exit 127]
After: ┊ 💻 $ ls bad 0.1s [ls: cannot access 'bad'...]
Adds a _trim_error helper that strips long absolute paths down to the
filename and caps the suffix at 48 chars so it stays readable on narrow
terminals.
Threads the tool result through the tool.completed progress callback so
agent/display.get_cute_tool_message can inspect it. The cli.py [error]
post-suffix is removed in favor of the richer suffix _detect_tool_failure
now produces directly.
Originally proposed in PR #17194 by Albert.Zhou; salvaged onto current
main with the dead-code preview-length bumps dropped (tool_preview_length
config already strictly caps previews, so the per-tool n= defaults are
unreachable).

The interactive CLI input path consults decide_image_input_mode() to pick
between native image_url attachment and the vision_analyze text pipeline,
but the non-interactive 'hermes chat -Q -q ... --image FOO' path
unconditionally called _preprocess_images_with_vision() — so even with
`model.supports_vision: true` set, --image always went through the
text-pipeline. Symptom: vision_analyze runs 4-5s per image and the model
sees a lossy text summary instead of the actual pixels.
Mirror the interactive path: load config, call decide_image_input_mode,
branch on native vs text. Falls back to the text-pipeline on any import
or build error (Pyright-clean: _build_parts guarded with `is not None`).

Add browser CDP launch candidates for Chrome, Chromium, Brave, and Edge while preserving Chrome-first selection. Retry candidate launch failures instead of giving up after the first executable.
Update /browser CLI and TUI messaging, docs, and tool descriptions from Chrome-only wording to Chromium-family browser support. Add regression coverage for Brave/Edge paths, Chrome-first precedence, fallback launches, and CDP endpoint probing.
`cli.py` was eager-importing `openai._base_client` at module-load time
purely to monkeypatch `AsyncHttpxClientWrapper.__del__` (defense against
"Press ENTER to continue..." errors when AsyncOpenAI clients are GC'd
against dead event loops). That import cost ~166ms / ~30MB on every
cold CLI start because openai's type tree (responses/*, graders/*) is huge.
Replace with a `sys.meta_path` finder that intercepts the first import
of `openai._base_client` from anywhere in the codebase, lets the normal
load run, then applies the `__del__ = lambda self: None` patch before
control returns to the caller. Same correctness guarantee (patch
applies before any AsyncOpenAI instance can be constructed), zero cost
until the SDK is actually needed.
Hot path: every hermes chat / gateway boot / cron tick / subagent spawn.
A/B benchmark, 10 runs each, fresh subprocess:

import cli wall 0.85s 0.59s -31% (min)
import cli RSS 91.2MB 74.0MB -19% (median)
The `neuter_async_httpx_del` function in agent/auxiliary_client.py is
unchanged; its tests still pass and any future callers can still invoke
it directly.
Verified:
- import cli no longer pulls openai into sys.modules
- first 'from openai._base_client import AsyncHttpxClientWrapper'
triggers the patch; __del__.__name__ == '<lambda>'
- tests/run_agent/test_async_httpx_del_neuter.py: 9/9 pass
- tests/agent/test_auxiliary_client.py: 159/159 pass
- tests/cli/: 715/715 pass
The SIGTERM/SIGHUP handler raised KeyboardInterrupt() at the end of its
agent-interrupt + grace-window sequence. Python delivers signals between
bytecodes on the main thread, so when the signal hit mid-event-loop
(typically inside prompt_toolkit's '_poll_output_size' coroutine's
'await asyncio.sleep()'), the KeyboardInterrupt unwound INTO that
coroutine. prompt_toolkit's Task captured it as a BaseException;
prompt_toolkit's '_handle_exception' then printed 'Unhandled exception
in event loop' + the full asyncio traceback and parked the terminal on
'Press ENTER to continue...' before exiting.
Same root cause as #13710, different surface: there the failure was an
EIO cascade after a logging-cache KeyError escaped the handler; here
it's the KBI raise itself landing inside an asyncio Task. The fix is
the same shape — let the event loop unwind on its own terms.
Now: schedule 'app.exit()' via 'loop.call_soon_threadsafe()'. The
prompt_toolkit Application returns normally from 'app.run()' and the
existing '(EOFError, KeyboardInterrupt, BrokenPipeError)' handler in
the input loop catches everything else. Fallback to 'raise
KeyboardInterrupt()' preserved for contexts where prompt_toolkit isn't
the active app (e.g. -q one-shot mode).
The agent interrupt + 1.5 s grace window run unchanged before the new
exit path, so subprocess-group cleanup ('os.killpg' on Linux) still
gets its window.
Tested live: external SIGTERM to the CLI (with 'kill <pid>') now exits
cleanly with no traceback dump and no ENTER pause.
Skill bundles are tiny YAML files in ~/.hermes/skill-bundles/ that
group several skills under one slash command. Invoking /<bundle-name>
from any surface (CLI, TUI, dashboard, any gateway platform) loads
every referenced skill into a single combined user message.
Use cases:
- /backend-dev → loads github-code-review + test-driven-development
+ github-pr-workflow as one bundle.
- /research → loads several research skills together.
- Team task profiles shared via dotfiles.
Behavior:
- Bundles take precedence over individual skills when slugs collide.
- Missing skills are skipped with a note, not fatal.
- No system-prompt mutation — bundles generate a fresh user message
at invocation time, the same way /<skill> does. Prompt cache stays
intact.
- Works in CLI dispatch, gateway dispatch, autocomplete (CLI + TUI),
/help display.
Schema (~/.hermes/skill-bundles/<slug>.yaml):
name: backend-dev
description: Backend feature work.
skills:
- github-code-review
- test-driven-development
instruction: |
Optional extra guidance prepended to the loaded skills.
New module: agent/skill_bundles.py — load, scan, resolve, build
invocation message, save, delete. yaml.safe_load only; broken
bundles log a warning and are skipped, never raise.
New CLI subcommand: hermes bundles {list,show,create,delete,reload}.
Implementation in hermes_cli/bundles.py; wired in hermes_cli/main.py.
'bundles' added to _BUILTIN_SUBCOMMANDS so plugin discovery skips it.
New in-session slash command: /bundles lists installed bundles in
both CLI and gateway. /<bundle-name> dispatch added to CLI (cli.py)
and gateway (gateway/run.py) before the existing /<skill-name> path.
Autocomplete: SlashCommandCompleter gained an optional
skill_bundles_provider parameter that defaults to None — the prompt
shows '▣ <description> (N skills)' for bundles vs '⚡' for skills.
Tests:
- tests/agent/test_skill_bundles.py — 33 tests covering slugify,
scan/cache freshness, resolve (including underscore→hyphen
Telegram alias), build_bundle_invocation_message (loading, missing
skills, user/bundle instruction injection, dedup), save/delete,
reload diff, list sort.
- tests/hermes_cli/test_bundles.py — 8 tests for the CLI
subcommand (create/list/show/delete/reload, --force, missing
bundle errors).
- tests/gateway/test_bundles_command.py — 4 tests for the gateway
handler and bundle resolution priority.
Live E2E: verified subprocess invocations of hermes bundles
{list,create,show,reload,delete} round-trip correctly against an
isolated HERMES_HOME.
Docs:
- website/docs/user-guide/features/skills.md — new 'Skill Bundles'
section with quick example, YAML schema, management commands,
behavior notes.
- website/docs/reference/cli-commands.md — 'hermes bundles' added to
the top-level command table and given its own subcommand section.
Salvages #23302 by @Bartok9. Four independent one-area fixes:
1. kanban boards delete alias now hard-deletes (not archives) — the
alias didn't carry --delete, so getattr(args, 'delete', False)
returned False. Detect boards_action=='delete' explicitly.
2. Gateway auto-title failures no longer leak as user-visible
warnings — debug-log only since they're not actionable.
3. Background process completion notification snaps truncation to
the next newline boundary, prepends a marker when content is
dropped.
4. _cprint() schedules the run_in_terminal coroutine via
asyncio.ensure_future so output isn't silently dropped from
background threads (fixes#23185 Bug A). Skips the
double-print fallback that would fire for mock paths.
Wraps _pt_print in try/except with a print() fallback. When a
kanban worker's stdout is piped to a log file, prompt_toolkit
raises NoConsoleScreenBufferError (Windows) or OSError (other)
because there is no real console buffer. The fallback keeps
worker output flowing instead of crashing.
* feat: add /update slash command to CLI and TUI
* test(cli): add Python tests for /update slash command
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix(cli): address Copilot review for /update slash command
Route classic CLI /update through prompt_toolkit modal confirmation and
defer relaunch to the main-thread cleanup path after app.exit(). Tighten
Y/n semantics, add Python wrapper and catalog coverage tests, and assert
/update stays visible in the TUI command catalog.

* fix(cli): address review feedback on /update command
- Replace raw input() with _prompt_text_input_modal in _handle_update_command
to avoid EOF/hang/keystroke-leak races with prompt_toolkit's stdin ownership
- Fix confirmation logic: only proceed on recognized affirmative aliases
(y/yes/1/ok); cancel on everything else including empty string, typos,
and unrecognized input — matches all other [Y/n] prompts in the codebase
- Route relaunch through main-thread shutdown path: set _pending_relaunch
and return False from process_command so process_loop triggers app.exit();
run() then calls relaunch() after prompt_toolkit has restored terminal modes
and after cleanup — safe on both POSIX (execvp) and Windows (subprocess+exit)
- Fix misleading docstring in test_update_command.py: the Vitest only covers
the TypeScript slash handler that emits code 42, not the Python wrapper
branch that acts on it
- Rewrite tests to use SimpleNamespace pattern (like test_destructive_slash_confirm)
so _prompt_text_input_modal can be stubbed directly
- Add Python test for _launch_tui exit-code-42 → relaunch branch in main.py

When auxiliary compression's summary generation returns None (aux model
errored, returned non-JSON, timed out, etc.) the compressor previously
still dropped every middle message between compress_start..compress_end
and replaced them with a static 'Summary generation was unavailable'
placeholder. The session kept going but the user silently lost N turns
of context for nothing.
New behavior: on summary failure, compress() aborts entirely — returns
the input messages unchanged and sets _last_compress_aborted=True. The
existing _summary_failure_cooldown_until gate (30-60s) keeps the aux
model from being burned on every turn. Auto-compress callers detect
the no-op (len(after) == len(before)) and stop looping. The chat is
'frozen' at its current size until the next /compress or /new.
Manual /compress (CLI + gateway) now passes force=True which clears
the cooldown so users can retry immediately after an auto-abort. If
the manual retry also fails, the user gets a visible warning telling
them nothing was dropped and how to retry.
- agent/context_compressor.py: compress() gains force= kwarg; failure
branch sets _last_compress_aborted and returns messages unchanged
instead of inserting placeholder.
- run_agent.py: _compress_context() detects abort, surfaces warning,
skips session-rotation entirely, returns messages unchanged.
- cli.py + gateway/run.py: manual /compress paths pass force=True.
- gateway/run.py: hygiene + /compress handlers detect _last_compress_aborted
and emit the new 'Compression aborted' warning (gateway.compress.aborted)
instead of the old 'N historical messages were removed' message.
- locales/*.yaml: new gateway.compress.aborted key in all 16 locales.
- tests: updated to assert the abort contract (messages preserved,
compression_count not incremented, abort flag set, no placeholder
leaked). New test_force_true_bypasses_failure_cooldown covers the
manual-retry path.
The Tab-completion lambda captured _skill_commands at startup, so newly
installed skills were missing from Tab completion even after /reload-skills
reported them as added.
Two changes:
1. Tab-completion lambda now calls get_skill_commands() instead of reading
the module-level _skill_commands snapshot — ensures the lambda always
gets fresh data without needing to touch global state.
2. _reload_skills() now syncs cli.py's module-level _skill_commands via
get_skill_commands() after reload, so help display, command dispatch,
and any other direct _skill_commands readers also see the updated map.
Closes#26441
Six days after #23937 (608 fixes) the codebase had accumulated 241 new
PLR6201 violations. Same mechanical `x in (...)` → `x in {...}` fix,
same zero-risk profile: set lookup is O(1) vs O(n) for tuple and the
two are semantically equivalent for hashable scalar membership tests.
All 241 instances fixed via `ruff check --select PLR6201 --fix
--unsafe-fixes`, zero remaining. Every changed value is a hashable
scalar (str/int/None/enum/signal); no risk of unhashable runtime
errors. No behavior change.
Test plan:
- 119 files changed, +244/-244 (net zero) — exactly one-line edits
- `ruff check` clean afterward
- Compile checks pass on the largest touched files (cli.py, run_agent.py,
gateway/run.py, gateway/platforms/discord.py, model_tools.py)
- Subset broad test run on tests/gateway/ tests/hermes_cli/ tests/agent/
tests/tools/: 18187 passed, 59 pre-existing failures (verified against
origin/main with the same shape — identical failure count, identical
category — all xdist test-order flakes unrelated to this change)
Follows the same template as PR #23937 ([tracker: #23972](https://github.com/NousResearch/hermes-agent/issues/23972)).
Adds logger.info when large pastes are collapsed to file
references in both paste-code paths (handle_paste and
_on_text_changed). Logs paste ID, line count, character
count, and file path so operators can correlate missing-
content reports with specific paste files. This is a
diagnostic aid, not a fix for the paste-drop issue.
Adds a pure-local recap of recent session activity — turn counts,
tools used, files touched, last user ask, last assistant reply —
appended to the existing /status output. Useful when juggling multiple
sessions and you want a one-glance reminder of where this one left off.
Inspired by Claude Code 2.1.114's /recap, but folded into /status so
we don't add a 6th info command. Pure local computation: no LLM call,
no auxiliary model, no prompt-cache invalidation, instant and free.
Salvage of #18587 — kept the shared hermes_cli.session_recap.build_recap
helper and its 13 unit tests, dropped the /recap slash command +
ACTIVE_SESSION_BYPASS_COMMANDS entry + Level-2 bypass since /status
already covers both surfaces.
Tailored to hermes-agent's tool vocabulary: file-editing tools
(patch, write_file, read_file, skill_manage, skill_view) surface
touched paths; tool-call counts highlight which classes of work
drove the session.

Surface live background-task count in the prompt_toolkit status bar so users
can see at a glance that a /background task exists and is running — no need
to ask the agent about it (the agent has no visibility into bg sessions by
design).
- _get_status_bar_snapshot now reports active_background_tasks from len()
of the live _background_tasks dict (entries are removed in the task
thread's finally block, so this reflects truly-running tasks)
- Indicator shown only on medium (<76) and wide (>=76) tiers; narrow (<52)
stays minimal since it's already cramped
- No invalidate plumbing needed: status bar fragments are pulled via lambda
on every redraw, and the bg thread already calls _app.invalidate() on exit
Refs #8568
Port from google-gemini/gemini-cli#19332.
Users can now exit with '/exit --delete' (or '/quit --delete', '/exit -d')
to permanently remove the current session's SQLite history plus on-disk
transcripts (*.json / *.jsonl / request_dump_*) in one shot. Useful for
privacy-sensitive workflows and one-off interactions where leaving a
session recording behind is undesirable.
Implementation:
- New HermesCLI._delete_session_on_exit one-shot flag (defaults False).
- process_command() parses --delete / -d after /exit or /quit and arms
the flag. Unknown args print a hint and keep the CLI running (prevents
typos like '/exit -delete' from accidentally exiting).
- Shutdown path calls SessionDB.delete_session(session_id, sessions_dir=...)
right after end_session() when the flag is set. That API already
existed for 'hermes sessions delete' and handles both SQLite removal
(orphaning child sessions so FK constraints hold) and on-disk file
cleanup.
- /quit CommandDef now advertises '[--delete]' in args_hint so /help
and CLI autocomplete surface it.
Tests: tests/cli/test_exit_delete_session.py (12 cases covering both
aliases, case insensitivity, whitespace, short form, unknown-arg
rejection, and registry metadata).
E2E-verified with isolated HERMES_HOME: session row deleted, all three
transcript/request-dump files removed, second delete_session call
correctly returns False.
Tirith ships no Windows binary, so on every Windows CLI startup users
saw a scary 'tirith security scanner enabled but not available' banner
they could not act on. The banner suggested degraded security; in
reality pattern-matching guards still run and the message was pure noise.
Fix:
- New public is_platform_supported() helper in tools/tirith_security.py
that returns False when _detect_target() doesn't resolve (Windows, any
non-x86_64/aarch64 arch).
- ensure_installed(), _resolve_tirith_path(), and check_command_security()
short-circuit on unsupported platforms: cache _resolved_path =
_INSTALL_FAILED with reason 'unsupported_platform', skip PATH probes,
skip the background download thread, skip the disk failure marker, and
return allow with an empty summary from check_command_security so the
spawn loop never fires.
- Explicit user-configured tirith_path is still honored everywhere (a
user who built tirith themselves under WSL keeps that path).
- CLI banner in cli.py gated on is_platform_supported() — fires only on
platforms where tirith *should* work but isn't installed.
- Docs note tirith's supported-platform list and point Windows users at
WSL.
Tests: tests/tools/test_tirith_security.py +8 tests covering Linux
x86_64, Darwin arm64, Windows, and unknown-arch verdicts plus the
silent ensure_installed / check_command_security / _resolve_tirith_path
fast-paths and the explicit-path override.
test_tirith_security.py 75 passed (8 new + 67 pre-existing)
test_command_guards.py 19 passed
When running with --yolo, all dangerous command approvals are bypassed.
Make this state visible so users don't forget:
- Banner: '⚠ YOLO mode — all approval prompts bypassed' line in red, only
shown when YOLO is active. Default case is silent (no extra line, no
always-on 'restricted' label).
- Status bar: '⚠ YOLO' fragment appended in red (#FF4444 bold) across all
three width tiers (<52, <76, ≥76) in both the plain-text fallback and
the fragments builder.

#25975 (salvaging #24403) clamped decorative scrollback Panels and
streaming box rules to `max(32, min(width, 56))` as a defense against
terminal-emulator reflow when columns shrink. On any modern wide
terminal this made the response/reasoning borders look stubby — 56
cols inside a 200-col viewport.
#26137 (salvaging #25981, by @OutThisLife) landed a more fundamental
fix: prompt_toolkit's `_output_screen_diff` is monkey-patched so its
reserve-vertical-space cursor move no longer pushes chrome into
scrollback at all. With that in place, the clamp is no longer
load-bearing for the chrome-into-scrollback class of bugs — the
remaining risk is purely cosmetic reflow of *already stamped*
Panel borders during an aggressive column shrink, which we now
accept as a tradeoff for restoring proper full-width rendering.
Changes:
- `_scrollback_box_width()` returns `max(32, width)` (just the floor,
no upper cap). All 10 call sites stay valid.
- Updated `test_scrollback_box_width_caps_to_resize_safe_value` to
the new `test_scrollback_box_width_returns_viewport_width` asserting
full-width passthrough above the 32-col floor.
Floor of 32 is kept so `'─' * (w - 2)` math stays positive on tiny
terminals.
Refs #18449#19280#22976 (the original reflow class) and #25975
(the clamp this reverts).
Two long-standing prompt_toolkit bugs in the base hermes CLI:
1. Resize duplication. Column-shrink resize used to push 40+ rows of
duplicate chrome (status bar, input rules) into terminal scrollback
every resize. Same wall as pt issues #29 (open since 2014), #1675,
#1933 — aider/xonsh/ipython all use alt-screen to dodge it.
Root cause (verified by reading prompt_toolkit/renderer.py):
_output_screen_diff (renderer.py L232-242) deliberately moves the
cursor to the bottom of the canvas after every paint 'to make sure
the terminal scrolls up'. In non-fullscreen mode this scrolls chrome
content into terminal scrollback on every render — not just on
resize.
Fix: monkey-patch prompt_toolkit.renderer._output_screen_diff to
bypass the reserve-vertical-space cursor move. When pt's logic checks
'if current_height > previous_screen.height', we inflate the previous
screen height so the branch falls through. ~30-line wrapper, no fork
of pt, no alt-screen, no DECSTBM scroll region.
Verified empirically in real Terminal.app: 10 resizes (mixed
shrinks/widens 1300→500→1400) during streaming produced ZERO
scrollback delta, full agent response preserved, status bar pinned
at bottom, no visible duplicates. pt is pinned to ==3.0.52 so the
private-function patch is safe; future pt bumps will need to
re-verify the signature matches.
2. Light-mode terminal visibility. Hardcoded skin colors (#FFF8DC
cornsilk, #FFD700 gold, #B8860B dark goldenrod) are tuned for dark
Terminal.app — invisible on light/cream backgrounds.
Port ui-tui/src/theme.ts detectLightMode() to Python so the base CLI
adapts. Detection priority: HERMES_LIGHT/HERMES_TUI_LIGHT env →
HERMES_TUI_THEME=light|dark → HERMES_TUI_BACKGROUND=#RRGGBB →
COLORFGBG env (xterm/Konsole/urxvt) → OSC 11 query
(\x1b]11;?\x1b\\) with 100ms timeout → default dark. OSC 11 is
tty-gated so gateway/cron/batch/subagent code paths don't pay the
timeout cost.
When light mode is detected, dark-mode colors auto-remap to readable
equivalents (#FFF8DC → #1A1A1A, #FFD700 → #9A6B00, etc). Hooked at
three points:
- _hex_to_ansi() — auto-remaps any color emitted via the ANSI helper
- _build_tui_style_dict() — rewrites pt style strings (chrome bg/fg)
- SkinConfig.get_color() — wrapped at module load so Rich Panel
borders/body text get the remap too
Status-bar foreground colors (#C0C0C0, #888888, etc.) are explicitly
skipped because they're paired with a dark navy bg — remapping them
would make them invisible in dark mode.
3. Other visibility fixes: [thinking] reasoning preview now uses ANSI
dim+italic (\x1b[2;3m) instead of #B8860B so it inherits terminal
default fg color. Input/prompt area defaults to terminal default fg
(was #FFF8DC cornsilk → invisible on cream).

On macOS with uv-managed cPython 3.11, the default kqueue selector cannot
register fd 0, so prompt_toolkit's loop.add_reader raises
OSError(EINVAL) ("[Errno 22] Invalid argument") from kqueue.control()
and the agent crashes immediately on startup (#5884, also reported in
#6393).
Probe KqueueSelector.register(0, EVENT_READ) before launching
prompt_toolkit. If it fails, install an event-loop policy that returns a
SelectorEventLoop backed by SelectSelector — select() works fine on
stdin in this Python build, so add_reader succeeds and the agent
launches normally.
Also extend the existing #6393 fallback handler to recognize EINVAL /
EBADF / "Invalid argument" so that any future selector failure on stdin
shows the friendly "reinstall Python via pyenv or Homebrew" guidance
instead of an opaque traceback.
Verified on macOS (Darwin 24.6.0) with uv-managed cPython 3.11.15: the
kqueue probe fails, the policy switch fires, and `hermes` launches
cleanly. No effect on platforms where kqueue can register fd 0.
The 'sessions' command has been registered in the central command
registry since #20805 (May 2025) and surfaces in /help and tab-completion,
but the classic CLI's process_command() never had an elif branch for it.
The canonical name fell through and printed 'Unknown command: sessions'.
The TUI side was wired up correctly via the SessionPicker overlay; only
the legacy CLI was missing the dispatch.
Adds _handle_sessions_command() which mirrors /resume's no-arg behavior
inline (the CLI has no overlay primitive equivalent to the TUI picker):
- /sessions and /sessions list → print the recent-sessions table
- /sessions <id_or_title> → delegates to _handle_resume_command
Includes regression tests covering the dispatcher wiring (the original
bug) plus the three handler branches.
When the terminal shrinks, already-printed box-drawing rules (response,
reasoning, streaming TTS, background-task Panels) reflow into multiple
narrower rows — visible as duplicated horizontal separators / ghost
lines in scrollback. Similarly, prompt_toolkit redraws a fresh status
bar on SIGWINCH on top of one the terminal just reflowed, producing
double-bar artifacts on column shrink.
Two surgical changes:
1. Decorative scrollback boxes now use a new
`HermesCLI._scrollback_box_width()` helper that clamps to
`max(32, min(width, 56))`. The live TUI footer is unaffected and still
uses the full width. Covers: streaming response box (open + close),
reasoning box (open + close, both streaming and post-stream paths),
streaming-TTS box close, final-response Rich Panel, and the
background-task Rich Panel.
2. `_recover_after_resize()` now also sets a new
`_status_bar_suppressed_after_resize` flag so the dynamic status bar
and both input separator rules stay hidden until the next user input.
The flag is cleared in the process loop the moment the user submits
their next prompt, restoring chrome cleanly.
Tests:
- New `test_input_rules_hide_after_resize_until_next_input` covers the
flag's effect on rule heights.
- New `test_scrollback_box_width_caps_to_resize_safe_value` covers the
helper at floor / cap / mid-range / overflow.
- Existing resize-recovery test extended to assert the flag flips.

The spinner already shows tool activity visually; the 1.2 kHz tone on
every tool.started event was unwanted noise (especially on WSL2, where
each beep also triggers Windows Terminal's bell notification).
Removed the play_beep call in _on_tool_progress entirely. Record
start/stop beeps (gated by voice.beep_enabled) are unaffected.
The _approval_callback method in HermesCLI hardcoded timeout=60
instead of reading the approvals.timeout config value. This meant
the config setting was silently ignored for CLI interactive prompts.
Other approval paths (callbacks.py, tools/approval.py) already read
the config correctly — only cli.py was missed.
* feat(goals): /subgoal — user-added criteria appended to active /goal
Layers a /subgoal command on top of the existing freeform Ralph judge
loop. The user can append extra criteria mid-loop; the judge factors
them into its done/continue verdict and the continuation prompt
surfaces them to the agent. No new tool, no agent self-judging — the
existing judge model just sees a richer prompt.
Forms:
/subgoal show current subgoals
/subgoal <text> append a criterion
/subgoal remove <n> drop subgoal n (1-based)
/subgoal clear wipe all subgoals
How it integrates:
- GoalState gains `subgoals: List[str]` (default []), backwards-compat
for existing state_meta rows.
- judge_goal accepts an optional subgoals kwarg; non-empty switches to
JUDGE_USER_PROMPT_WITH_SUBGOALS_TEMPLATE which lists them as
numbered criteria and asks 'is the goal AND every additional
criterion satisfied?'
- next_continuation_prompt picks CONTINUATION_PROMPT_WITH_SUBGOALS_TEMPLATE
when non-empty so the agent sees what to target.
- /subgoal is allowed mid-run on the gateway since it only touches the
state the judge reads at turn boundary — no race with the running
turn.
- Status line shows '... , N subgoals' when present.
Surface:
- hermes_cli/goals.py — field, prompt blocks, manager methods, judge weave
- hermes_cli/commands.py — /subgoal CommandDef
- cli.py — _handle_subgoal_command
- gateway/run.py — _handle_subgoal_command + mid-run dispatch
- tests/hermes_cli/test_goals.py — 15 new tests (backcompat, mutation,
persistence, prompt template selection, judge-prompt content via mock,
status-line rendering)
77 goal-related tests passing across goals + cli + gateway + tui.
* fix(goals): slash commands don't preempt the goal-continuation hook
Two findings from live-testing /subgoal:
1. Slash commands queued while the agent is running landed in
_pending_input (same queue as real user messages). The goal hook's
'is a real user message pending?' check returned True and silently
skipped — but the slash command consumes its queue slot via
process_command() which never re-fires the goal hook, so the loop
stalls indefinitely. Now the hook peeks the queue and only defers
when a non-slash payload is present.
2. The with-subgoals judge prompt was too soft — opus 4.7 said 'done,
implying all requirements met' without verifying. Tightened to
demand specific per-criterion evidence (file contents, output line,
command result) and explicitly reject phrases like 'implying it was
done.'
Live verified: /subgoal injected mid-loop now correctly forces the
judge to refuse done until the new criterion is met. Agent gets the
continuation prompt with subgoals listed, updates the script, judge
confirms done with specific evidence cited.
The interactive CLI /model picker was the third call-site duplicating
the inline config-slice + list_authenticated_providers pattern that
PR #23666 consolidated for the dashboard and TUI. Route it through
load_picker_context() + build_models_payload() too so all surfaces
that show authenticated providers share one substrate.
Side effect: cli.py now also benefits from the latent v12+ keyed
providers fix (custom_providers populated via
get_compatible_custom_providers, not cfg.get raw).
The aux-task switcher (hermes_cli/main.py) and gateway model
switcher (gateway/run.py) deliberately stay on the legacy path —
they use different config sections (auxiliary.<task>.*) and a
different config loader (_load_gateway_config) respectively, so
forcing them through ConfigContext would either overload its
semantics or grow the module past the clean refactor scope.
* feat(codex-runtime): scaffold optional codex app-server runtime
Foundational commit for an opt-in alternate runtime that hands OpenAI/Codex
turns to a 'codex app-server' subprocess instead of Hermes' tool dispatch.
Default behavior is unchanged.
Lands in three pieces:
1. agent/transports/codex_app_server.py — JSON-RPC 2.0 over stdio speaker
for codex's app-server protocol (codex-rs/app-server). Spawn, init
handshake, request/response, notification queue, server-initiated
request queue (for approval round-trips), interrupt-friendly blocking
reads. Tested against real codex 0.130.0 binary end-to-end during
development.
2. hermes_cli/runtime_provider.py:
- Adds 'codex_app_server' to _VALID_API_MODES.
- Adds _maybe_apply_codex_app_server_runtime() helper, called at the
end of _resolve_runtime_from_pool_entry(). Inert unless
'model.openai_runtime: codex_app_server' is set in config.yaml AND
provider in {openai, openai-codex}. Other providers cannot be
rerouted (anthropic, openrouter, etc. preserved).
3. tests/agent/transports/test_codex_app_server_runtime.py — 24 tests
covering api_mode registration, the rewriter helper (default-off,
case-insensitive, opt-in, non-eligible providers preserved), version
parser, missing-binary handling, error class. Does NOT require codex
CLI installed.
This commit is wire-only: the api_mode is recognized but AIAgent does
not yet branch on it. Followup commits add the session adapter, event
projector, approval bridge, transcript projection (so memory/skill
review still works), plugin migration, and slash command.
Existing tests remain green:
- tests/cli/test_cli_provider_resolution.py (29 passed)
- tests/agent/test_credential_pool_routing.py (included above)
* feat(codex-runtime): add codex item projector for memory/skill review
The translator that lets Hermes' self-improvement loop keep working under the
Codex runtime: converts codex 'item/*' notifications into Hermes' standard
{role, content, tool_calls, tool_call_id} message shape that
agent/curator.py already knows how to read.
Item taxonomy (matches codex-rs/app-server-protocol/src/protocol/v2/item.rs):
- userMessage → {role: user, content}
- agentMessage → {role: assistant, content: text}
- reasoning → stashed in next assistant's 'reasoning' field
- commandExecution → assistant tool_call(name='exec_command') + tool result
- fileChange → assistant tool_call(name='apply_patch') + tool result
- mcpToolCall → assistant tool_call(name='mcp.<server>.<tool>') + tool result
- dynamicToolCall → assistant tool_call(name=<tool>) + tool result
- plan/hookPrompt/etc → opaque assistant note, no fabricated tool_calls
Invariants preserved:
- Message role alternation never violated: each tool item produces at most
one assistant + one tool message in that order, correlated by call_id.
- Streaming deltas (item/<type>/outputDelta, item/agentMessage/delta)
don't materialize messages — only item/completed does. Mirrors how
Hermes already only writes the assistant message after streaming ends.
- Tool call ids are deterministic (codex item id-based) so replays produce
identical messages and prefix caches stay valid (AGENTS.md pitfall #16).
- JSON args use sorted_keys for the same reason.
Real wire formats verified against codex 0.130.0 by capturing live
notifications from thread/shellCommand and including one as a fixture
(COMMAND_EXEC_COMPLETED).
23 new tests, all green:
- Streaming deltas don't materialize (3 paths)
- Turn/thread frame events are silent
- commandExecution: 5 tests including non-zero exit annotation +
deterministic id stability across replays
- agentMessage + reasoning attachment + reasoning consumption
- fileChange: summary without inlined content
- mcpToolCall: namespaced naming + error surfacing
- userMessage: text fragments only (drops images/etc)
- opaque items: no fabricated tool_calls
- Helpers: deterministic id stability + sorted JSON args
- Role alternation invariant across all four tool-shaped item types
This commit is a pure addition. AIAgent integration (the wire that uses the
projector) is the next commit.
* feat(codex-runtime): add session adapter + approval bridge
The third self-contained module: CodexAppServerSession owns one Codex
thread per Hermes session, drives turn/start, consumes streaming
notifications via CodexEventProjector, handles server-initiated approval
requests, and translates cancellation into turn/interrupt.
The adapter has a single public per-turn method:
result = session.run_turn(user_input='...', turn_timeout=600)
# result.final_text → assistant text for the caller
# result.projected_messages → list ready to splice into AIAgent.messages
# result.tool_iterations → tick count for _iters_since_skill nudge
# result.interrupted → True on Ctrl+C / deadline / interrupt
# result.error → error string when the turn cannot complete
# result.turn_id, thread_id → for sessions DB / resume
Behavior:
- ensure_started() spawns codex, does the initialize handshake, and
issues thread/start with cwd + permissions profile. Idempotent.
- run_turn() blocks until turn/completed, drains server-initiated
requests (approvals) before reading notifications so codex never
deadlocks waiting for us, projects every item/completed via the
projector, and increments tool_iterations for the skill nudge gate.
- request_interrupt() is thread-safe (threading.Event); the next loop
iteration issues turn/interrupt and unwinds.
- turn_timeout deadlock guard issues turn/interrupt and records an
error if the turn never completes.
- close() escalates terminate → kill via the underlying client.
Approval bridge:
Codex emits server-initiated requests for execCommandApproval and
applyPatchApproval. The adapter translates Hermes' approval choice
vocabulary onto codex's decision vocabulary:
Hermes 'once' → codex 'approved'
Hermes 'session' or 'always' → codex 'approvedForSession'
Hermes 'deny' / anything else → codex 'denied'
Routing precedence:
1. _ServerRequestRouting.auto_approve_* flags (cron / non-interactive)
2. approval_callback wired by the CLI (defers to
tools.approval.prompt_dangerous_approval())
3. Fail-closed denial when neither is wired
Unknown server-request methods are answered with JSON-RPC error -32601
so codex doesn't hang waiting for us.
Permission profile mapping mirrors AGENTS.md:
Hermes 'auto' → codex 'workspace-write'
Hermes 'approval-required' → codex 'read-only-with-approval'
Hermes 'unrestricted/yolo' → codex 'full-access'
20 new tests, all green. Combined with prior commits this PR now has
67 tests across three modules:
- test_codex_app_server_runtime.py: 24 (api_mode + transport surface)
- test_codex_event_projector.py: 23 (item taxonomy projections)
- test_codex_app_server_session.py: 20 (turn loop + approvals + interrupts)
Full tests/agent/transports/ directory: 249/249 pass — no regressions
to existing transport tests.
Still no wire into AIAgent.run_conversation(); that integration commit
is small and goes next.
* feat(codex-runtime): wire codex_app_server runtime into AIAgent
The integration commit. AIAgent.run_conversation() now early-returns to a
new helper _run_codex_app_server_turn() when self.api_mode ==
'codex_app_server', bypassing the chat_completions tool loop entirely.
Three small surgical edits to run_agent.py (~105 LOC total):
1. Line ~1204 (constructor api_mode validation set):
Add 'codex_app_server' so an explicit api_mode='codex_app_server'
passed to AIAgent() isn't silently rewritten to 'chat_completions'.
2. Line ~12048 (run_conversation, just before the while loop):
Early-return to _run_codex_app_server_turn() when self.api_mode is
'codex_app_server'. Placed AFTER all standard pre-loop setup —
logging context, session DB, surrogate sanitization, _user_turn_count
and _turns_since_memory increments, _ext_prefetch_cache, memory
manager on_turn_start — so behavior outside the model-call loop is
identical between paths. Default Hermes flow is unchanged when the
flag is off.
3. End-of-class (line ~15497):
New method _run_codex_app_server_turn(). Lazy-instantiates one
CodexAppServerSession per AIAgent (reused across turns), runs the
turn, splices projected_messages into messages, increments
_iters_since_skill by tool_iterations (since the chat_completions
loop normally does that per iteration), fires
_spawn_background_review on the same cadence as the default path.
Counter accounting:
_turns_since_memory ← already incremented at run_conversation:11817
(gated on memory store configured) — codex
helper does NOT touch it (would double-count).
_user_turn_count ← already incremented at run_conversation:11793
— codex helper does NOT touch it.
_iters_since_skill ← incremented in the chat_completions loop per
tool iteration. Codex helper increments by
turn.tool_iterations since the loop is bypassed.
User message:
ALREADY appended to messages by run_conversation pre-loop (line 11823)
before the early-return reaches us. Helper does NOT append again.
Regression test test_user_message_not_duplicated guards this.
Approval callback wiring:
Lazy-fetches tools.terminal_tool._get_approval_callback at session
spawn time, passes to CodexAppServerSession. CLI threads with
prompt_toolkit get interactive approvals; gateway/cron contexts get
the codex-side fail-closed deny.
Error path:
Codex session exceptions become a 'partial' result with completed=False
and a final_response that explicitly tells the user how to switch back:
'Codex app-server turn failed: ... Fall back to default runtime with
/codex-runtime auto.' Same return-dict shape as the chat_completions
path so all callers (gateway, CLI, batch_runner, ACP) work unchanged.
9 new integration tests in tests/run_agent/test_codex_app_server_integration.py:
- api_mode='codex_app_server' is accepted on AIAgent construction
- run_conversation returns the expected codex shape
(final_response, codex_thread_id, codex_turn_id, completed, partial)
- Projected messages are spliced into messages list
- _iters_since_skill ticks per tool iteration
- _user_turn_count delegated to standard flow (not double-counted)
- User message appears exactly once (regression guard)
- _spawn_background_review IS invoked (memory/skill review keeps working)
- chat.completions.create is NEVER called (loop fully bypassed)
- Session exception → partial result with /codex-runtime auto hint
- Interrupted turn → partial result with error preserved
Adjacent test runs confirm no regressions:
- tests/run_agent/test_memory_nudge_counter_hydration.py: green
- tests/run_agent/test_background_review.py: green
- tests/run_agent/test_fallback_model.py: green
- tests/agent/transports/: 249/249 green

are the remaining followup commits.
* feat(codex-runtime): add /codex-runtime slash command (CLI + gateway)
User-facing toggle for the optional codex app-server runtime. Follows the
'Adding a Slash Command (All Platforms)' pattern from AGENTS.md exactly:
single CommandDef in the central registry → CLI handler → gateway handler
→ running-agent guard → all surfaces (autocomplete, /help, Telegram menu,
Slack subcommands) update automatically.
Surface:
/codex-runtime — show current state + codex CLI status
/codex-runtime auto — Hermes default runtime
/codex-runtime codex_app_server — codex subprocess runtime
/codex-runtime on / off — synonyms
Files changed:
hermes_cli/codex_runtime_switch.py (new):
Pure-Python state machine shared by CLI and gateway. Parse args,
read/write model.openai_runtime in the config dict, gate enabling
behind a codex --version check (don't let users opt in to a runtime
they have no binary for; print npm install hint instead).
Returns a CodexRuntimeStatus dataclass that callers render however
suits their surface.
hermes_cli/commands.py:
Single CommandDef entry, no aliases (codex-runtime is its own thing).
cli.py:
Dispatch in process_command() + _handle_codex_runtime() handler that
delegates to the shared module and renders results via _cprint.
gateway/run.py:
Dispatch in _handle_message() + _handle_codex_runtime_command() that
returns a string (gateway sends as message). On a successful change
that requires a new session, _evict_cached_agent() forces the next
inbound message to construct a fresh AIAgent with the new api_mode —
avoids prompt-cache invalidation mid-session.
gateway/run.py running-agent guard:
/codex-runtime joins /model in the early-intercept block so a runtime
flip mid-turn can't split a turn across two transports.
Tests:
tests/hermes_cli/test_codex_runtime_switch.py — 25 tests covering the
state machine: arg parsing (10 cases incl. case-insensitive and
synonyms), reading current runtime (5 cases incl. malformed configs),
writing runtime (3 cases), apply() entry point covering read-only,
no-op, codex-missing-blocked, codex-present-success, disable-no-binary-check,
and persist-failure paths (8 cases). All green.
Adjacent test suites confirm no regressions:
- tests/hermes_cli/test_commands.py + test_codex_runtime_switch.py:
167/167 green
- tests/agent/transports/: 283/283 green when combined with prior commits
Still missing: plugin migration helper, docs page, live e2e test gated on
codex binary. Followup commits.
* feat(codex-runtime): auto-migrate Hermes MCP servers to ~/.codex/config.toml
Translates the user's mcp_servers config from ~/.hermes/config.yaml into
the TOML format codex's MCP client expects. Wired into the
/codex-runtime codex_app_server enable path so users get their MCP tool
surface in the spawned subprocess automatically.
The migration runs on every enable. Failures are non-fatal — the runtime
change still proceeds and the user gets a warning so they can fix the
codex config manually.
What translates (mapping verified against codex-rs/core/src/config/edit.rs):
Hermes mcp_servers.<n>.command/args/env → codex stdio transport
Hermes mcp_servers.<n>.url/headers → codex streamable_http transport
Hermes mcp_servers.<n>.timeout → codex tool_timeout_sec
Hermes mcp_servers.<n>.connect_timeout → codex startup_timeout_sec
Hermes mcp_servers.<n>.cwd → codex stdio cwd
Hermes mcp_servers.<n>.enabled: false → codex enabled = false
What does NOT translate (warned + skipped per server):
Hermes-specific keys (sampling, etc.) — codex's MCP client has no
equivalent. Listed in the per-server skipped[] field of the report.
What's NOT migrated (intentional):
AGENTS.md — codex respects this file natively in its cwd. Hermes' own
AGENTS.md (project-level) is already in the worktree, so codex picks
it up without translation. No code needed.
Idempotency design:
All managed content lives between a 'managed by hermes-agent' marker
and the next non-mcp_servers section header. _strip_existing_managed_block
removes the prior managed region cleanly, preserving any user-added
codex config (model, providers.openai, sandbox profiles, etc.) above
or below.
Files added:
hermes_cli/codex_runtime_plugin_migration.py — pure-Python migration
helper. Public API: migrate(hermes_config, codex_home=None,
dry_run=False) returns MigrationReport with .migrated/.errors/
.skipped_keys_per_server. No external TOML dependency — minimal
formatter handles strings/numbers/booleans/lists/inline-tables.
tests/hermes_cli/test_codex_runtime_plugin_migration.py — 39 tests
covering:
- per-server translation (12): stdio/http/sse, cwd, timeouts,
enabled flag, command+url precedence, sampling drop, unknown keys
- TOML formatter (8): types, escaping, inline tables, error case
- existing-block stripping (4): no marker, alone, with user content
above, with user content below
- end-to-end migrate() (8): empty, dry-run, round-trip, idempotent
re-run, preserves user config, error reporting, invalid input,
summary formatting
Files changed:
hermes_cli/codex_runtime_switch.py — apply() now calls migrate() in
the codex_app_server enable branch. Migration failure logs a warning
in the result message but does NOT fail the runtime change. Disable
path (auto) explicitly skips migration.
tests/hermes_cli/test_codex_runtime_switch.py — 3 new tests:
test_enable_triggers_mcp_migration, test_disable_does_not_trigger_migration,
test_migration_failure_does_not_block_enable.
All 325 feature tests green:
- tests/agent/transports/: 249 (incl. 67 new)
- tests/run_agent/test_codex_app_server_integration.py: 9
- tests/hermes_cli/test_codex_runtime_switch.py: 28 (3 new)
- tests/hermes_cli/test_codex_runtime_plugin_migration.py: 39 (new)
* perf(codex-runtime): cache codex --version check within apply()
Single /codex-runtime invocation could spawn 'codex --version' up to 3
times (state report, enable gate, success message). Each spawn is ~50ms,
so the cumulative cost wasn't a crisis, but it was wasteful and turned a
trivial slash command into something noticeably laggy on slower systems.
Refactored to lazy-once via a closure over a nonlocal cache. First call
spawns; subsequent calls in the same apply() reuse the result.
Behavior unchanged — same return shape, same error handling, same install
hint when codex is missing. Just one subprocess per call instead of three.
Two regression-guard tests added:
- test_binary_check_cached_within_apply: enable path → call_count == 1
- test_binary_check_cached_on_read_only_call: state-report path → call_count == 1
Total tests for /codex-runtime now 30 (was 28); all 143 codex-runtime
tests still green.
* fix(codex-runtime): correct protocol field names found via live e2e test
Three real bugs caught only by running a turn end-to-end against codex
0.130.0 with a real ChatGPT subscription. Unit tests passed because they
asserted on our own (incorrect) wire shapes; the wire format from
codex-rs/app-server-protocol/src/protocol/v2/* is the source of truth and
my initial reading of the README was incomplete.
Bug 1: thread/start.permissions wire format
Was sending {"profileId": "workspace-write"}.
Real format per PermissionProfileSelectionParams enum (tagged union):
{"type": "profile", "id": "workspace-write"}
AND requires the experimentalApi capability declared during initialize.
AND requires a matching [permissions] table in ~/.codex/config.toml or
codex fails the request with 'default_permissions requires a [permissions]
table'.
Fix: stop overriding permissions on thread/start. Codex picks its default
profile (read-only unless user configures otherwise), which matches what
codex CLI users expect — they configure their default permission profile
in ~/.codex/config.toml the standard way. Trying to be clever about
profile selection broke every turn we tested.
Live error before fix: 'Invalid request: missing field type' on every
turn/start, even though our turn/start payload was correct — the field
codex was complaining about was inside the permissions sub-object we
shouldn't have been sending.
Bug 2: server-request method names
Was matching 'execCommandApproval' and 'applyPatchApproval'.
Real names per common.rs ServerRequest enum:
item/commandExecution/requestApproval
item/fileChange/requestApproval
item/permissions/requestApproval (new third method)
Fix: match the documented names. Added handler for
item/permissions/requestApproval that always declines — codex sometimes
asks to escalate permissions mid-turn and silent acceptance would surprise
users.
Live symptom before fix: agent.log showed
'Unknown codex server request: item/commandExecution/requestApproval'
and codex stalled because we replied with -32601 (unsupported method)
instead of an approval decision. The agent reported back 'The write
command was rejected' even though Hermes never showed the user an
approval prompt.
Bug 3: approval decision values
Was sending decision strings 'approved'/'approvedForSession'/'denied'.
Real values per CommandExecutionApprovalDecision enum (camelCase):
accept, acceptForSession, decline, cancel
(also AcceptWithExecpolicyAmendment and ApplyNetworkPolicyAmendment
variants we don't currently use).
Fix: rename _approval_choice_to_codex_decision return values; update
auto_approve_* fallbacks; update fail-closed default from 'denied' to
'decline'. Test mapping table updated to match.
Live test verified after fixes:
$ hermes (with model.openai_runtime: codex_app_server)
> Run the shell command: echo hermes-codex-livetest > .../proof.txt
then read it back
Approval prompt fired with 'Codex requests exec in <cwd>'.
User chose 'Allow once'. Codex executed the command, wrote the file,
read it back. Final response: 'Read back from proof.txt:
hermes-codex-livetest'. File contents on disk match.
agent.log confirms:
codex app-server thread started: id=019e200e profile=workspace-write
cwd=/tmp/hermes-codex-livetest/workspace
All 20 session tests still green after wire-format updates.
* fix(codex-runtime): correct apply_patch approval params + ship docs
Live e2e revealed FileChangeRequestApprovalParams doesn't carry the
changeset (just itemId, threadId, turnId, reason, grantRoot) — Codex's
'reason' field describes what the patch wants to do. Test config and
display logic updated to use it. The first 'apply_patch (0 change(s))'
display from the live test is now 'apply_patch: <reason>'.
Adds website/docs/user-guide/features/codex-app-server-runtime.md
covering enable/disable, prerequisites, approval UX, MCP migration
behavior, permission profile delegation to ~/.codex/config.toml, known
limitations, and the architecture diagram. Wired into the Automation
category in sidebars.ts.
Live e2e validation across the path matrix:
✓ thread/start handshake
✓ turn/start with text input
✓ commandExecution items + projection
✓ item/commandExecution/requestApproval → Hermes UI → response
✓ Approve once → command runs
✓ Deny → command rejected, codex falls back to read-only message
✓ Multi-turn (codex remembers prior turn's results)
✓ apply_patch via Codex's fileChange path
✓ item/fileChange/requestApproval → Hermes UI
✓ MCP server migration loads inside spawned codex (verified via
'use the filesystem MCP tool' prompt)
✓ /codex-runtime auto → codex_app_server toggle cycle
✓ Disable doesn't trigger migration
✓ Enable with codex CLI present succeeds + migrates
✓ Hermes-side interrupt path (turn/interrupt request issued cleanly
even if codex finishes before the interrupt lands)
Known live-validated limitations now documented in the docs page:
- delegate_task subagents unavailable on this runtime
- permission profile selection delegated to ~/.codex/config.toml
- apply_patch approval prompt has no inline changeset (codex protocol
doesn't expose it)
145/145 codex-runtime tests still green.
* feat(codex-runtime): native plugin migration + UX polish (quirks 2/4/5/10/11)
Major: migrate native Codex plugins (#7 in OpenClaw's PR list)
Discovers installed curated plugins via codex's plugin/list RPC and
writes [plugins."<name>@<marketplace>"] entries to ~/.codex/config.toml
so they're enabled in the spawned Codex sessions. This is the
'YouTube-video-worthy' bit Pash highlighted: when a user has
google-calendar, github, etc. installed in their Codex CLI, those
plugins activate automatically when they enable Hermes' codex runtime.
Implementation:
- hermes_cli/codex_runtime_plugin_migration.py: new _query_codex_plugins()
helper spawns 'codex app-server' briefly and walks plugin/list. Returns
(plugins, error) — failures are non-fatal so MCP migration still works.
- render_codex_toml_section() now takes plugins + permissions args.
- migrate() defaults: discover_plugins=True, default_permission_profile=
'workspace-write'. Explicit None on either disables that side.
- _strip_existing_managed_block() now also strips [plugins.*] and
[permissions]/[permissions.*] sections inside the managed block, so
re-runs replace plugins cleanly without touching codex's own config.
Quirk fixes:
#2 Default permissions profile written on enable.
Without this, Codex's read-only default kicks in and EVERY write
triggers an approval prompt. Now writes [permissions] default =
'workspace-write' so the runtime feels normal out of the box. Set
default_permission_profile=None to opt out.
#4 apply_patch approval prompt now shows what's changing.
Codex's FileChangeRequestApprovalParams doesn't carry the changeset.
Session adapter now caches the fileChange item from item/started
notifications and looks it up by itemId when codex requests approval.
Prompt shows '1 add, 1 update: /tmp/new.py, /tmp/old.py' instead of
'apply_patch (0 change(s))'.
Side benefit: also drains pending notifications BEFORE handling a
server request, so the projector and per-turn caches are up to date
when the approval decision fires. Bounded to 8 notifications per
loop iter to avoid starving codex's response.
#5/#10 Exec approval prompt never shows empty cwd.
When codex omits cwd in CommandExecutionRequestApprovalParams, fall
back to the session's cwd. If somehow neither is available, show
'<unknown>' explicitly instead of an empty string.
Also surfaces 'reason' from the approval params when codex provides
it — gives users more context on why codex wants to run something.
#11 Banner indicates the codex_app_server runtime when active.
New 'Runtime: codex app-server (terminal/file ops/MCP run inside
codex)' line appears in the welcome banner only when the runtime is
on. Default banner is unchanged.
Tests:
- 7 new tests in test_codex_runtime_plugin_migration.py covering
plugin discovery (mocked), failure handling, dry-run skip, opt-out
flag, idempotent re-runs, and permissions writing.
- 3 new tests in test_codex_app_server_session.py covering the
enriched approval prompts: cwd fallback, change summary on
apply_patch, fallback when no item/started cache exists.
- All 26 session tests + 46 migration tests green; 153 total in PR.
* feat(codex-runtime): hermes-tools MCP callback + native plugin migration
The big architectural addition: when codex_app_server runtime is on,
Hermes registers its own tool surface as an MCP server in
~/.codex/config.toml so the codex subprocess can call back into Hermes
for tools codex doesn't ship with — web_search, browser_*, vision,
image_generate, skills, TTS.
Also: 'migrate native codex plugins' (Pash's YouTube-video-worthy bit) —
when the user has plugins like Linear, GitHub, Gmail, Calendar, Canva
installed via 'codex plugin', Hermes discovers them via plugin/list and
writes [plugins.<name>@openai-curated] entries so they activate
automatically.
New module: agent/transports/hermes_tools_mcp_server.py
FastMCP stdio server exposing 17 Hermes tools. Each call dispatches
through model_tools.handle_function_call() — same code path as the
Hermes default runtime. Run with:
python -m agent.transports.hermes_tools_mcp_server [--verbose]
Exposed: web_search, web_extract, browser_navigate / _click / _type /
_press / _snapshot / _scroll / _back / _get_images / _console /
_vision, vision_analyze, image_generate, skill_view, skills_list,
text_to_speech.
NOT exposed (deliberately):
- terminal/shell/read_file/write_file/patch — codex has built-ins
- delegate_task/memory/session_search/todo — _AGENT_LOOP_TOOLS in
model_tools.py:493, require running AIAgent context. Documented
as a limitation and surfaced in the slash command output.
Migration changes (hermes_cli/codex_runtime_plugin_migration.py):
- _query_codex_plugins() spawns 'codex app-server' briefly to walk
plugin/list and pull installed openai-curated plugins. Failures are
non-fatal — MCP migration still completes.
- render_codex_toml_section() now takes plugins + permissions args
AND wraps the managed block with a MIGRATION_END_MARKER comment so
the stripper can reliably find both ends, even when the block
contains top-level keys (default_permissions = ...).
- migrate() defaults: discover_plugins=True, expose_hermes_tools=True,
default_permission_profile=':workspace' (built-in codex profile name
— must be prefixed with ':'). All three opt-out via explicit args.
- _build_hermes_tools_mcp_entry() builds the codex stdio entry with
HERMES_HOME and PYTHONPATH passthrough so a worktree-launched
Hermes points the MCP subprocess at the same module layout.
Live-caught wire bugs fixed during this turn:
1. Permission profile config key is top-level , NOT a [permissions] table. The [permissions] table is
for *user-defined* profiles with structured fields. Built-in
profile names start with ':' (':workspace', ':read-only',
':danger-no-sandbox'). Was emitting
which codex rejected with 'invalid type: string "X", expected
struct PermissionProfileToml'.
2. Built-in profile is , NOT . Codex
rejected with 'unknown built-in profile'.
3. Codex's MCP layer sends for
tool-call confirmation. We weren't handling it, so codex stalled
and returned 'MCP tool call was rejected'. Now: auto-accept for
our own hermes-tools server (user already opted in by enabling
the runtime), decline for third-party servers.
Quirk fixes shipped (from the limitations list):
#2 default permissions: workspace profile written on enable. No more
approval prompt on every write.
#4 apply_patch approval shows what's changing: cache fileChange
items from item/started, look up by itemId when codex sends
item/fileChange/requestApproval. Prompt: '1 add, 1 update:
/tmp/new.py, /tmp/old.py' instead of '0 change(s)'.
#5/#10 exec approval cwd never empty: fall back to session cwd, then
'<unknown>'. Also surfaces 'reason' from codex when present.
#11 banner shows 'Runtime: codex app-server' line when active so
users understand why tool counts may not match what's reachable.
Tests:
- 5 new tests in test_codex_runtime_plugin_migration.py covering
plugin discovery, expose_hermes_tools entry generation, idempotent
re-runs, opt-out flag, permissions profile.
- 3 new tests in test_codex_app_server_session.py covering enriched
approval prompts (cwd fallback, fileChange summary).
- 2 new tests for mcpServer/elicitation/request handling (accept
hermes-tools, decline others).
- New test file test_hermes_tools_mcp_server.py covering module
surface, EXPOSED_TOOLS safety invariants (no shell/file_ops,
no agent-loop tools), and main() error paths.
- 166 codex-runtime tests total, all green.
Live e2e validated against codex 0.130.0 + ChatGPT subscription:
✓ /codex-runtime codex_app_server enables, migrates filesystem MCP,
registers hermes-tools, writes default_permissions = ':workspace'
✓ Banner shows 'Runtime: codex app-server' line in subsequent sessions
✓ Shell command runs without approval prompt (workspace profile works)
✓ Multi-turn — codex remembers prior turn's results
✓ apply_patch path via fileChange request approval
✓ web_search via hermes-tools MCP callback returns real Firecrawl
results: 'OpenAI Codex CLI – Getting Started' end-to-end in 13s
✓ Disable cycle clean
Docs updated: website/docs/user-guide/features/codex-app-server-runtime.md
Full re-write covering native plugin migration, the hermes-tools
callback architecture, the prerequisites change ('codex login is
separate from hermes auth login codex'), the trade-off table now
reflecting which Hermes tools work via callback, and the limitations
list updated with what's actually unavailable on this runtime.
* feat(codex-runtime): pin user-config preservation invariant for quirk #6
Quirk #6 from the limitations list — user MCP servers / overrides /
codex-only sections in ~/.codex/config.toml that live OUTSIDE the
hermes-managed block must survive re-migration verbatim.
This already worked thanks to the MIGRATION_MARKER + MIGRATION_END_MARKER
pair I added when fixing the default_permissions wire format (so the
strip can find both ends of the managed region even with top-level
keys like default_permissions). But it was an emergent property
without a test pinning it.
Now explicitly tested:
- User MCP server above the managed block survives migration
- User MCP server below the managed block survives migration
- Both above + below survive a second re-migration
- User content (model, providers, sandbox, otel, etc.) outside our
region is left untouched
Docs added a section "Editing ~/.codex/config.toml safely" explaining
the marker contract — so users know they can add their own MCP
servers, override permissions, configure codex-only options, etc.
without fear of Hermes overwriting their work.
167 codex-runtime tests, all green.
* docs(codex-runtime): clarify the actual tool surface — shell covers terminal/read/write/find
Previous docs and PR description undersold what codex's built-in
toolset actually provides. apply_patch alone made it sound like the
runtime could only edit files in patch format — implying you'd lose
terminal use, read_file, write_file, search/find. That was wrong.
Codex's 'shell' tool runs arbitrary shell commands inside the sandbox,
which covers everything you'd do in bash: cat/head/tail (read), echo>
or heredocs (write), find/rg/grep (search), ls/cd (navigate), build/
test/git/etc. apply_patch is for structured multi-file edits on top
of that. update_plan is its in-runtime todo. view_image loads images.
And codex has its own web_search built in (in addition to the
Firecrawl-backed one Hermes exposes via MCP callback).
Docs now have a 'What tools the model actually has' section right
after Why, breaking the surface into three clearly-labeled buckets:
1. Codex's built-in toolset (always on) — shell, apply_patch,
update_plan, view_image, web_search; covers everything terminal-
adjacent.
2. Native Codex plugins (auto-migrated from your codex plugin
install) — Linear, GitHub, Gmail, Calendar, Outlook, Canva, etc.
3. Hermes tool callback (MCP server in ~/.codex/config.toml) —
web_search/web_extract via Firecrawl, browser_*, vision_analyze,
image_generate, skill_view/skills_list, text_to_speech.
Plus a 'What's NOT available' callout listing the four agent-loop tools
(delegate_task, memory, session_search, todo) that need running
AIAgent context and can't reach the codex runtime.
Trade-offs table broken out: shell, apply_patch, update_plan,
view_image, sandbox each get their own row with a one-line description
so users can see at a glance what's available natively.
Architecture diagram updated to list the codex built-ins by name
instead of 'apply_patch + shell + sandbox'.
No code changes — purely docs clarification. 167 codex-runtime tests
still green.
* fix(codex-runtime): _spawn_background_review signature + review fork api_mode downgrade
Two real bugs in the self-improvement loop integration that the previous
test mocked away.
Bug 1: wrong call signature
The codex helper was calling self._spawn_background_review() with no
args after every turn. That function actually requires:
messages_snapshot=list (positional or keyword)
review_memory=bool (at least one trigger must be True)
review_skills=bool
So the call would have raised TypeError at runtime — except the only
test that exercised this path mocked _spawn_background_review entirely
and just asserted spawn.called, so the wrong-arg shape never surfaced.
Bug 2: review fork inherits codex_app_server api_mode
The review fork is constructed with:
api_mode = _parent_runtime.get('api_mode')
So when the parent is codex_app_server, the review fork ALSO runs as
codex_app_server. But the review fork's whole job is to call agent-loop
tools (memory, skill_manage) which require Hermes' own dispatch — they
short-circuit with 'must be handled by the agent loop' on the codex
runtime. So the review fork would have run, decided to save something,
called memory or skill_manage, and silently no-op'd.
Fixed in run_agent.py:_spawn_background_review() — when the parent
api_mode is 'codex_app_server', the review fork is downgraded to
'codex_responses' (same OAuth credentials, same openai-codex provider,
but talks to OpenAI's Responses API directly so Hermes owns the loop).
Also rewrote the codex helper's review wiring to match the
chat_completions path:
- Computes _should_review_memory in the pre-loop block (was already
being computed; now passed through to the helper as an arg).
- Computes _should_review_skills AFTER the codex turn returns +
counters tick (line ~15432 pattern in chat_completions).
- Calls _spawn_background_review(messages_snapshot=, review_memory=,
review_skills=) only when at least one trigger fires.
- Adds the external memory provider sync (_sync_external_memory_for_turn)
that the chat_completions path runs after every turn.
Tests:
Replaced the broken test_background_review_invoked (which only
asserted spawn.called) with three sharper tests:
- test_background_review_NOT_invoked_below_threshold:
single turn at default thresholds → no review fires (would have
caught the original 'every turn calls spawn with no args' bug)
- test_background_review_skill_trigger_fires_above_threshold:
10 tool_iterations at threshold=10 → review fires with
messages_snapshot=list, review_skills=True, counter resets
- test_background_review_signature_never_breaks: regression guard
asserting positional args are always empty and kwargs include
messages_snapshot
New TestReviewForkApiModeDowngrade class:
- test_codex_app_server_parent_downgrades_review_fork: drives the
real _spawn_background_review function (no mock at that level),
asserts the review_agent gets api_mode='codex_responses' when
the parent was codex_app_server.
Live-validated against real run_conversation:
- Counter ticked from 0 to 5 after a 5-tool-iteration turn
- _spawn_background_review fired exactly once with kwargs-only signature
- review_skills=True, review_memory=False
- messages_snapshot was 12 entries (5 assistant tool_calls + 5 tool
results + 1 final assistant + initial system/user)
- Counter reset to 0 after fire
170 codex-runtime tests, all green.
Docs: added a Self-improvement loop section to the codex runtime page
explaining both how the trigger logic stays equivalent and that the
review fork is auto-downgraded to codex_responses for the agent-loop
tools. Also clarified that apply_patch and update_plan ARE codex's
built-in tools (the previous version made it sound like they were
separate from 'codex's stuff' — they're not, all five tools listed
in 'What tools the model actually has' section 1 are codex built-ins).
* feat(codex-runtime): expose kanban tools through Hermes MCP callback
Kanban workers spawn as separate hermes chat -q subprocesses that read
the user's config.yaml. If model.openai_runtime: codex_app_server is set
globally (which is the whole point of opt-in), every dispatched worker
ALSO comes up on the codex runtime.
That mostly works — codex's built-in shell + apply_patch + update_plan
do the actual task work fine — but it had one critical break: the
worker handoff tools (kanban_complete, kanban_block, kanban_comment,
kanban_heartbeat) are Hermes-registered tools, not codex built-ins.
On the codex runtime, codex builds its own tool list and these never
reach the model, so the worker would do the work but not be able to
report back, hanging until the dispatcher's timeout escalates it as
zombie.
Fix: add all 9 kanban tools to the EXPOSED_TOOLS list in the Hermes
MCP callback. They dispatch statelessly through handle_function_call()
just like web_search and the others — they read HERMES_KANBAN_TASK
from env (set by the dispatcher), gate correctly (worker tools require
the env var, orchestrator tools require it unset), and write to
~/.hermes/kanban.db.
Why kanban tools work via stateless dispatch when delegate_task/memory/
session_search/todo don't: those four are listed in _AGENT_LOOP_TOOLS
(model_tools.py:493) and short-circuit in handle_function_call() with
'must be handled by the agent loop' — they need to mutate AIAgent's
mid-loop state. Kanban tools have no such requirement; they're pure
side-effect functions against the kanban.db plus state_meta.
Tools exposed:
Worker handoff (require HERMES_KANBAN_TASK):
kanban_complete, kanban_block, kanban_comment, kanban_heartbeat
Read-only board queries:
kanban_show, kanban_list
Orchestrator (require HERMES_KANBAN_TASK unset):
kanban_create, kanban_unblock, kanban_link
Tests:
- test_kanban_worker_tools_exposed: complete/block/comment/heartbeat
in EXPOSED_TOOLS (regression guard for the would-hang-worker bug)
- test_kanban_orchestrator_tools_exposed: create/show/list/unblock/link
Docs:
- New 'Workflow features' section in the docs page covering /goal,
kanban, and cron behavior on this runtime
- /goal: works fully via run_conversation feedback; only caveat is
approval-prompt noise on long writes-heavy goals (mitigated by
the default :workspace permission profile)
- Kanban: enumerated which tools are reachable via the callback and
why the env var propagates correctly through the codex subprocess
to the MCP server subprocess
- Cron: documented as 'not specifically tested' — same rules as the
CLI apply since cron runs through AIAgent.run_conversation
- Trade-offs table gained rows for /goal, kanban worker, kanban
orchestrator
172/172 codex-runtime tests green (+2 from kanban tests).
* docs(codex-runtime): wire /codex-runtime into slash-commands ref + flag aux token cost
Three docs gaps caught during a final audit:
1. /codex-runtime was only in the feature docs page, not in the
slash-commands reference. Added rows to both the CLI section and
the Messaging section so users discover it where they'd look for
slash command syntax.
2. CODEX_HOME and HERMES_KANBAN_TASK weren't in environment-variables.md.
CODEX_HOME lets users redirect Codex CLI's config dir (the migration
honors it). HERMES_KANBAN_TASK is set by the kanban dispatcher and
propagates to the codex subprocess + the hermes-tools MCP subprocess
so kanban worker tools gate correctly — documented as 'don't set
manually' since it's an internal handoff.
3. Aux client behavior on this runtime. When openai_runtime=
codex_app_server is on with the openai-codex provider, every aux
task (title generation, context compression, vision auto-detect,
session search summarization, the background self-improvement review
fork) flows through the user's ChatGPT subscription by default.
This is true for the existing codex_responses path too, but it's
more visible / important here because users explicitly opted in for
subscription billing. Added a 'Auxiliary tasks and ChatGPT
subscription token cost' section to the docs page with a YAML
example showing how to override specific aux tasks to a cheaper
model (typically google/gemini-3-flash-preview via OpenRouter).
Also documents how the self-improvement review fork gets
auto-downgraded from codex_app_server to codex_responses by the
fix earlier in this PR.
No code changes — pure docs. 172 codex-runtime tests still green.
* docs+test(codex-runtime): pin HOME passthrough, document multi-profile + CODEX_HOME
OpenClaw hit a real footgun in openclaw/openclaw#81562: when spawning
codex app-server they were synthesizing a per-agent HOME alongside
CODEX_HOME. That made every subprocess codex's shell tool launches
(gh, git, aws, npm, gcloud, ...) see a fake $HOME and miss the user's
real config files. They had to back it out in PR #81562 — keep
CODEX_HOME isolation, leave HOME alone.
Audit confirms Hermes' codex spawn doesn't have this problem. We do
os.environ.copy() and only overlay CODEX_HOME (when provided) and
RUST_LOG. HOME passes through unchanged. But it was an emergent
property without a test pinning it, so adding a regression guard:
test_spawn_env_preserves_HOME — confirms parent HOME survives intact
in the subprocess env
test_spawn_env_sets_CODEX_HOME_when_provided — confirms codex_home
arg still isolates
codex state correctly
Docs additions:
'HOME environment variable passthrough' section — calls out the
contract explicitly: CODEX_HOME isolates codex's own state, HOME
stays user-real so gh/git/aws/npm/etc. find their normal config.
Cites openclaw#81562 as the cautionary tale.
'Multi-profile / multi-tenant setups' section — addresses the
related concern: profiles share ~/.codex/ by default. For users who
want per-profile codex isolation (separate auth, separate plugins),
documents the manual CODEX_HOME=<profile-scoped-dir> approach.
Explains why we DON'T auto-scope CODEX_HOME per profile: doing so
would silently invalidate existing codex login state for anyone
upgrading to this PR with tokens already at ~/.codex/auth.json.
Opt-in is safer than surprising users.
174 codex-runtime tests (+2 from HOME guards), all green.
* fix(codex-runtime): TOML control-char escapes + atomic config.toml write
Two footguns caught in a final audit pass before merge.
Bug 1: TOML control characters not escaped
The _format_toml_value() helper escaped backslashes and double quotes
but passed literal control characters (\n, \t, \r, \f, \b) through
unchanged. TOML basic strings don't allow literal control characters
— a path or env var containing a newline would produce invalid TOML
that codex refuses to load.
Realistic exposure: pathological cases like a HERMES_HOME with a
trailing newline (env var concatenation accident), or a PYTHONPATH
with a tab from a multi-line shell heredoc.
Fix: escape all five TOML basic-string control sequences (\b \t \n
\f \r) in addition to \\ and \" that we already did. Order
matters — backslash must come first or the other escapes get
re-escaped.
Bug 2: config.toml write wasn't atomic
If the python process crashed between target.mkdir() and the
write_text() finishing, a half-written config.toml could be left
behind. On NFS / Windows / some FUSE mounts this is a real concern;
on ext4/APFS small writes are usually atomic in practice but not
guaranteed.
Fix: write to a tempfile.mkstemp() temp file in the same directory,
then Path.replace() (atomic same-dir rename on POSIX, ReplaceFile on
Windows). On rename failure, clean up the temp file so repeated
failed migrations don't pile up .config.toml.* files.
Tests:
- test_string_with_newline_escaped — \n in value → \n in output
- test_string_with_tab_escaped — \t in value → \t in output
- test_string_with_other_controls_escaped — \r, \f, \b
- test_windows_path_escaped_correctly — backslash doubling
- test_atomic_write_no_temp_leak_on_success — no .config.toml.*
left over after a successful write
- test_atomic_write_cleanup_on_rename_failure — temp file removed
when Path.replace raises (simulated disk full)
180 codex-runtime tests, all green (+6 from this commit).
Footguns audited but NOT fixed (with rationale):
- Concurrent migrations race. Two Hermes processes hitting
/codex-runtime codex_app_server within seconds of each other could
cause one writer to lose entries. Low probability (you'd have to
enable from two surfaces simultaneously) and low impact (just re-run
migration). Adding fcntl/msvcrt locking is more code than it's
worth here. The atomic rename above means each individual write is
consistent — only the merge step is racy.
- Codex protocol version drift. We pin MIN_CODEX_VERSION=0.125 and
check at runtime but don't reject too-new versions. Right call —
the protocol has been stable through 0.125 → 0.130. If OpenAI
breaks it later we'd see the error in test_codex_app_server_runtime
on CI before users hit it.
Recover from SIGWINCH without clearing the physical screen or scrollback
buffer. The startup banner and tool summary are printed before
prompt_toolkit owns the live chrome, so they live in normal terminal
scrollback. Calling erase_screen() + \x1b[3J] on every resize removed
that UI permanently — _replay_output_history cannot reconstruct it
because the banner was never added to _OUTPUT_HISTORY.
Instead, just reset prompt_toolkit's renderer cache and invalidate so
the next incremental redraw starts from a clean slate, then let the
original on_resize handler recalculate layout for the new terminal
size. This matches the behaviour of bash/zsh/fish on SIGWINCH.

Replace `len(label)` with `HermesCLI._status_bar_display_width(label)`
in two places where the response box top border is rendered.
`len()` counts characters, not terminal columns. CJK characters like
`测` and `试` each occupy 2 columns, causing the top border
`╭─ 测试 ───╮` to render 2 columns wider than the bottom border
`╰─────────╯`.
The `_status_bar_display_width` helper already exists (line 2881) and
uses `prompt_toolkit.utils.get_cwidth` for proper CJK width calculation.
* feat(security): supply-chain advisory checker + lazy-install framework + tiered install fallback
Three coordinated mitigations for the Mini Shai-Hulud worm hitting
mistralai 2.4.6 on PyPI (2026-05-12) and for the next single-package
compromise that follows.
# What this PR makes true
1. Users with the poisoned mistralai 2.4.6 in their venv get a loud
detection banner with copy-pasteable remediation steps the moment
they run hermes (and on every gateway startup).
2. One quarantined / yanked PyPI package can no longer silently demote
a fresh install to 'core only' — the installer keeps every other
extra and tells the user which tier landed.
3. Future opt-in backends (Mistral, ElevenLabs, Honcho, etc.) can
lazy-install on first use under a strict allowlist, instead of
eagerly pulling everything at install time.
# Detection: hermes_cli/security_advisories.py
- ADVISORIES catalog (one entry currently: shai-hulud-2026-05 for
mistralai==2.4.6). Adding the next one is a single dataclass.
- detect_compromised() uses importlib.metadata.version() — no pip
dependency, works in uv venvs that lack pip.
- Banner cache (~/.hermes/cache/advisory_banner_seen) rate-limits
the startup banner to once per 24h per advisory.
- Acks persisted to security.acked_advisories in config.yaml; never
re-banner after ack.
- Wired into:
* hermes doctor — runs first, prints full remediation block
* hermes doctor --ack <id> — dismisses an advisory
* cli.py interactive run() and single-query branches — short
stderr banner pointing at hermes doctor
* gateway/run.py startup — operator-visible warning in gateway.log
# Lazy-install framework: tools/lazy_deps.py
- LAZY_DEPS allowlist maps namespaced feature keys (tts.elevenlabs,
memory.honcho, provider.bedrock, etc.) to pip specs.
- ensure(feature) installs missing deps in the active venv via the
uv → pip → ensurepip ladder (matches tools_config._pip_install).
- Strict spec safety regex rejects URLs, file paths, shell metas,
pip flag injection, control chars — only PyPI-by-name accepted.
- Gated on security.allow_lazy_installs (default true) plus the
HERMES_DISABLE_LAZY_INSTALLS env var for restricted/audited envs.
- Migrated three backends as proof of pattern:
* tools/tts_tool.py — _import_elevenlabs() calls ensure first
* plugins/memory/honcho/client.py — get_honcho_client lazy-installs
* tts.mistral / stt.mistral entries pre-registered for when PyPI
restores mistralai
# Installer fallback tiers
scripts/install.sh, scripts/install.ps1, setup-hermes.sh:
- Centralised _BROKEN_EXTRAS list (currently: mistral). Edit one
array when a transitive breaks; users keep every other extra.
- New 'all minus known-broken' tier between [all] and the existing
PyPI-only-extras tier. Only kicks in when [all] fails resolve.
- All three tiers explicit: every fallback announces which tier
landed and prints a re-run hint when not on Tier 1.
- install.ps1 and install.sh both regenerate their tier specs from
the same _BROKEN_EXTRAS array so updates stay in sync.
Side effect: install.ps1 Tier 2 spec previously hardcoded 'mistral'
in its extra list — bug fixed by the refactor (mistral is filtered
out).
# Config
hermes_cli/config.py — DEFAULT_CONFIG.security gains:
- acked_advisories: [] (advisory IDs the user has dismissed)
- allow_lazy_installs: True (security gate for ensure())
No config version bump needed — both keys nest under existing
security: block, and load_config's deep-merge picks up DEFAULT_CONFIG
defaults for users with older configs.
# Tests
tests/hermes_cli/test_security_advisories.py — 23 tests covering:
- detect_compromised matches/non-matches, wildcard frozenset
- ack persistence, idempotence, blank rejection, config-failure path
- banner cache rate limiting + 24h re-banner + ack-stops-banner
- short_banner_lines / full_remediation_text / render_doctor_section /
gateway_log_message
- shipped catalog well-formedness invariant
tests/tools/test_lazy_deps.py — 40 tests covering:
- spec safety: 11 safe parametrized + 18 unsafe parametrized
- allowlist: unknown-feature rejection, namespace.name shape,
every shipped spec passes the safety regex
- security gating: config flag, env var, default, fail-open
- ensure() happy/sad paths: already-satisfied, install success,
pip stderr surfaced on failure, install-succeeds-but-still-missing
- is_available, feature_install_command
Combined: 63 new tests, all passing under scripts/run_tests.sh.

* build(deps): pin every direct dep to ==X.Y.Z (no ranges)
Companion to the supply-chain advisory work: replace every >=/</~= range
in pyproject.toml's [project.dependencies] and [project.optional-dependencies]
with an exact ==X.Y.Z pin sourced from uv.lock.
Why: ranges allow PyPI to ship a fresh version of any direct dep at any
time without a code review on our side. With ranges, the malicious
mistralai 2.4.6 release would have been pulled by every fresh
'pip install -e .[all]' for the hours between upload and PyPI's
quarantine — exactly the install window we got hit on. Exact pins close
that window: the only way a new package version reaches a user is via
an intentional update on our end.
What the user-facing change is: nothing, behavior-wise. Every package
resolves to the same version it was already resolving to via uv.lock —
the pins just remove the resolver's freedom to pick a different one.
Cost: any user installing Hermes alongside another package that requires
a newer pin gets a resolver conflict. Acceptable for our isolated-venv
install path; documented in the new comment block.
Build-system requires line (setuptools>=61.0) is intentionally left
as a range — pinning the build backend would block fresh pip from
bootstrapping the build on architectures where that exact wheel isn't
available.
mistral extra (mistralai==2.3.0) is pinned but stays out of [all]
(per PR #24205). 'uv lock' regeneration will fail until PyPI restores
mistralai; lockfile regeneration is gated behind that, NOT on every PR.
LAZY_DEPS in tools/lazy_deps.py also moved to exact pins so the lazy-
install pathway can never resolve a different version than the one
declared in pyproject.toml.
Validation:
- Cross-checked all 77 pinned direct deps in pyproject.toml against
uv.lock — every pin matches the resolved version exactly.
- Cross-checked all LAZY_DEPS specs against uv.lock — same.
- 'uv pip install -e .[all] --dry-run' resolves 205 packages cleanly.
- tests/tools/test_lazy_deps.py + tests/hermes_cli/test_security_advisories.py
→ 63/63 passing (every shipped spec passes the safety regex).
- Doctor + TTS + transcription targeted suite → 146/146 passing.
* build(deps): hash-verify transitives via uv.lock; remove unresolvable [mistral] extra
You asked: 'what about the dependencies the dependencies rely on?' —
correctly noting that exact-pinning direct deps in pyproject.toml does
NOT cover the transitive graph. `pip install` and `uv pip install` both
re-resolve transitives fresh from PyPI at install time, so a compromised
transitive (e.g. `httpcore` if it got worm-poisoned tomorrow) would
still hit our users even with every direct dep exact-pinned.
# What this commit fixes
1. **Both real installer scripts now prefer `uv sync --locked` as Tier 0.**
uv.lock records SHA256 hashes for every transitive — a compromised
package with a different hash gets REJECTED. Falls through to the
existing `uv pip install` cascade if the lockfile is missing or
stale, with a loud warning that the fallback path does NOT
hash-verify transitives. Previously only `setup-hermes.sh` (the dev
path) used the lockfile; `scripts/install.sh` and `scripts/install.ps1`
(the paths fresh users actually run) skipped it.
2. **Removed the `[mistral]` extra entirely.** The `mistralai` PyPI
project is fully quarantined right now — every version returns 404,
so any pin we wrote was unresolvable, which broke `uv lock --check`
in CI. Restoration is documented in pyproject.toml as a 5-step
checklist (verify, re-add extra, re-enable in 4 modules, regenerate
lock, optionally re-add to [all]).
3. **Regenerated uv.lock.** 262 packages, mistralai/eval-type-backport/
jsonpath-python pruned. `uv lock --check` now passes.
# Defense-in-depth view
| Layer | Where | Protects against |
|----------------------------|-------------------|-------------------------------------------|
| Exact pins in pyproject | direct deps | new mistralai 2.4.6-style direct compromise |
| uv.lock + `--locked` install | transitive graph | transitive worm injection |
| Tier-0 hash-verified path | install.sh / .ps1 | actually USE the lockfile in fresh installs |
| `uv lock --check` CI gate | every PR | drift between pyproject and lockfile |
| `hermes_cli/security_advisories.py` | runtime | cleanup for users who already got hit |
The exact pinning + hash verification together close the supply-chain
gap. Without the lockfile path, exact pins alone are theater.
# Validation
- `uv lock --check` → passes (262 packages resolved, no drift).
- `bash -n` on install.sh + setup-hermes.sh → OK.
- 209/209 tests passing across new + adjacent test files
(test_lazy_deps.py, test_security_advisories.py, test_doctor.py,
test_tts_mistral.py, test_transcription_tools.py).
- TOML parse OK.
* chore: remove community announcement drafts (PR body covers it)
* build(deps): lazy-install every opt-in backend (anthropic, search, terminal, platforms, dashboard)
Extends the lazy-install framework to cover everything that's not used by
every hermes session. Base install drops from ~60 packages to 45.
Moved out of core dependencies = []:
- anthropic (only when provider=anthropic native, not via aggregators)
- exa-py, firecrawl-py, parallel-web (search backends; only when picked)
- fal-client (image gen; only when picked)
- edge-tts (default TTS but still optional)
New extras in pyproject.toml: [anthropic] [exa] [firecrawl] [parallel-web]
[fal] [edge-tts]. All added to [all].
New LAZY_DEPS entries: provider.anthropic, search.{exa,firecrawl,parallel},
tts.edge, image.fal, memory.hindsight, platform.{telegram,discord,matrix},
terminal.{modal,daytona,vercel}, tool.dashboard.
Each import site now calls ensure() before importing the SDK. Where the
module had a top-level try/except (telegram, discord, fastapi), the
graceful-fallback pattern was extended to lazy-install on first
check_*_requirements() call and re-bind module globals.
Updated test_windows_native_support.py tzdata check from snapshot
(>=2023.3 literal) to invariant (any version + win32 marker).
Validation:
- Base install: 45 packages (was ~60); 6 newly-extracted packages absent
- uv lock --check: passes (262 packages, no drift)
- 209/209 lazy_deps + advisory + doctor + tts/transcription tests passing
- py_compile clean on all 12 modified modules
Follow-up to #23863 (CJK table alignment). The realigner was
correctly padding pipes to identical column offsets, but when a
table's natural width exceeds terminal cells it produced lines that
the terminal soft-wrapped mid-cell, destroying column alignment
visually even though the bytes were perfectly padded. Reported as
'columns are not aligned' on tables containing one long row alongside
several short rows.
Approach mirrors Claude Code's MarkdownTable.tsx narrow-terminal
fallback: when realign_markdown_tables is given an available_width
budget and the rebuilt horizontal table exceeds it, render each body
row as 'Header: value' lines separated by a thin ─ rule. Word-wraps
oversize values at the budget with a 2-space continuation indent.
- agent/markdown_tables.py: realign_markdown_tables(text, available_width=None);
threshold check at the top of _render_block flips into a new
_render_vertical fallback. Includes _wrap_to_width with hard-break
for tokens longer than the budget.
- cli.py: helper _terminal_width_for_streaming() returns
shutil.get_terminal_size().columns minus _STREAM_PAD and a 2-cell
safety margin; passed to all three realign call sites
(_render_final_assistant_content for strip+render Panel paths, and
the streaming flushers in _emit_stream_text / _flush_stream).
- tests/agent/test_markdown_tables.py: 4 new tests covering the
overflow-vertical fallback for ASCII + CJK content, the
'fits → keep horizontal' case, and the long-cell wrap with indent.
Live-verified: with COLUMNS=100, the user's reported 'long row in
ASCII table' case now renders as vertical key-value rows that all fit
the panel; the 6-column CJK comparison table still renders as an
aligned horizontal table because it fits inside 100 cols.
Replace with for all literal-tuple
membership tests. Set lookup is O(1) vs O(n) for tuple — consistent
micro-optimization across the codebase.
608 instances fixed via `ruff --fix --unsafe-fixes`, 0 remaining.
133 files, +626/-626 (net zero).
CJK and emoji glyphs render as two terminal cells but JS String#length
and the model's own padding count them as one, so any markdown table
with Chinese / Japanese / Korean cells drifts right per row when a
real terminal renders it. Both surfaces fix this with a display-cell
width measurement (wcswidth on the Python side, stringWidth on the
TUI side).
Changes:
- agent/markdown_tables.py: new helper. realign_markdown_tables(text)
detects markdown table blocks (header + |---| divider) and
rewrites the row padding using wcwidth.wcswidth so every pipe and
dash lines up across rows. No-op on text without tables.
- cli.py: hook the helper into _render_final_assistant_content for
strip / render modes (raw passes through untouched), and into the
streaming line emitter so live token-by-token rendering also
produces aligned tables. A small two-buffer state machine in
_emit_stream_text holds table rows until the block ends, then
flushes them through the realigner so all rows pad to a single
per-column width.
- ui-tui/src/components/markdown.tsx: renderTable now uses
stringWidth (Bun.stringWidth fast path + East-Asian-width-aware
fallback, already memoised in @hermes/ink) instead of UTF-16
String#length for both column-width measurement and per-cell
padding. Drops the comment that documented the bug as a deliberate
limitation.
Validation:
- New tests/agent/test_markdown_tables.py (11): every rebuilt block
shares pipe column offsets across rows for pure CJK, mixed
CJK+emoji, ragged-row, and multi-table inputs.
- Updated tests/cli/test_cli_markdown_rendering.py: the existing
strip-mode test asserted exact whitespace; rewritten to assert the
alignment contract (cell content survives + every rendered row
shares pipe offsets).
- New ui-tui markdown.test.ts case (1): rendered column-2 start
offset is identical for the header + every body row, including
the CJK row that drifted before the fix.
- Live: hermes chat -q with the user-reported screenshot prompt now
produces a perfectly aligned table on the wire (header, divider,
4 body rows including '通义千问', all pipes at identical columns).
- getattr(self, '_slash_confirm_state', None) at the two read sites that
trip object.__new__(HermesCLI) test fixtures (test_cli_external_editor,
test_cli_skin_integration)
- _build_tui_layout_children: make slash_confirm_widget keyword-only with
default None to avoid breaking subclassing extension hook for wrapper
CLIs (test_cli_extension_hooks)

terminal.docker_extra_args:
- List of extra flags appended verbatim to docker run after security
defaults. Useful for adding capabilities (e.g. --cap-add SETUID) or

* feat(goals): /goal checklist + /subgoal user controls
Two-phase judge for /goal — Phase A decomposes the goal into a detailed
checklist on first turn; Phase B evaluates each pending item harshly
against the agent's most recent response. The goal completes only when
every item is in a terminal status (completed or impossible). Adds
/subgoal so the user can append, complete, mark impossible, undo,
remove, or clear items the judge missed or got wrong.
Mechanics:
- GoalState gains `checklist` and `decomposed` fields, both backwards
compatible (old state_meta rows load unchanged).
- Phase A: aux call writes a harsh, exhaustive checklist; biased toward
more items not fewer. Falls through to legacy freeform judge when
decompose fails.
- Phase B: judge gets the checklist + last-response snippet + path to
a per-session conversation dump at <HERMES_HOME>/goals/<sid>.json.
A bounded read_file tool (max 5 calls per turn, restricted to that
one file) lets the judge inspect history when the snippet is
ambiguous. Stickiness in code: terminal items are frozen, only the
user can revert via /subgoal undo.
- Continuation prompt shows checklist progress when non-empty;
reverts to old prompt when empty.
- Status line shows M/N done counts.
CLI + gateway + TUI gateway all pass the agent reference into
evaluate_after_turn so the dump can be written. Gateway-side
/subgoal is allowed mid-run since it only modifies the checklist
the judge consults at turn boundaries.
Tests: 24 new cases — backcompat round-trip, Phase A decompose,
Phase B updates + new_items + stickiness, user override flows,
conversation dump (incl. unsafe-sid sanitization), judge read_file
restriction. Existing freeform-mode tests updated to patch the
renamed `judge_goal_freeform` and skip Phase A explicitly.
* fix(goals): off-by-one in judge index, message-list plumbing, prompt tuning
Three live-test findings from running /goal end-to-end against
gemini-3-flash-preview as the judge:
1. Off-by-one bug — the judge sees the checklist rendered with 1-based
indices ('1. [ ] foo, 2. [ ] bar') but the apply layer indexed
state.checklist as 0-based. Result: every judge update landed on
the wrong item, evidence got attached to neighbouring rows, and
the genuine 'first pending' item (usually #1) never got marked.
Fix: convert 1 → 0 in _parse_evaluate_response. Also tightened the
user prompt to call out the 1-based scheme explicitly. New tests
cover the parser conversion + an end-to-end fake-judge round-trip.
2. Conversation dump never happened — _extract_agent_messages tried
common AIAgent attribute names (.messages, .conversation_history,
etc.) but AIAgent doesn't expose the message list as an instance
attribute; it lives inside run_conversation()'s scope. Result: the
judge's read_file tool always saw history_path=unavailable. Fix:
added an explicit messages= kwarg to evaluate_after_turn that all
three call sites (CLI, gateway, TUI gateway) now pass directly.
Agent-attribute extraction kept as back-compat fallback.
3. Prompt was too harsh on simple goals. The original 'be HARSH,
default to leaving items pending' wording made the judge refuse
to mark 'file exists' completed even after the agent ran ls,
test -f, os.path.isfile, and find — burning the entire 8-turn
budget on a fizzbuzz task. Softened to 'strict but not absurd'
with explicit guidance on what counts as evidence and a directive
not to require re-proving items already established earlier.
Re-tested live with the same fizzbuzz goal: now terminates in 2
turns with all 8 checklist items correctly attributed to their
own evidence. /subgoal user-action flow (add / complete / undo /
impossible) verified live as well.
Slash commands (/clear, /new, /undo, /reload-mcp) are dispatched from the
process_loop daemon thread. prompt_toolkit.run_in_terminal returns a
coroutine that only the main-thread event loop can drive, so calling it
from a daemon thread orphans the coroutine — the input prompt never
renders and user keystrokes leak into the composer instead of the
confirmation prompt (issue #23185).
Mirror the thread-aware guard already in _run_curses_picker: when off the
main thread, fall back to a direct input() call. Also wrap
run_in_terminal in try/except so WSL / Warp / other emulators that
silently drop the scheduled coroutine fall back to input() too.
Tests: tests/cli/test_prompt_text_input_thread_safety.py covers main
thread (run_in_terminal path), daemon thread (direct input fallback),
no-app, run_in_terminal-raises, and EOF handling.
Builds on @kshitijk4poor's CLI handoff stub. The original PR's flow
deferred everything to whenever a real user happened to message the
target platform; this rewrites it so the gateway picks up handoffs
immediately and the destination chat just starts working.
State machine on sessions table replaces the boolean flag:
None -> 'pending' -> 'running' -> ('completed' | 'failed')
plus handoff_error for failure reasons. CLI request_handoff /
get_handoff_state / list_pending_handoffs / claim_handoff /
complete_handoff / fail_handoff helpers wrap the transitions.
CLI side (cli.py): /handoff <platform> validates the platform's home
channel via load_gateway_config, refuses if the agent is mid-turn,
flips the row to 'pending', and poll-blocks (60s) on terminal state.
On 'completed' it prints the /resume hint and exits the CLI like
/quit. On 'failed' or timeout it surfaces the reason and the CLI
session stays intact.
Gateway side (gateway/run.py): new _handoff_watcher background task
scans state.db every 2s, atomically claims pending rows, and runs
_process_handoff for each. _process_handoff:
1. Resolves the platform's home channel.
2. Asks the adapter for a fresh thread via the new
create_handoff_thread(parent_chat_id, name) capability so the
handed-off conversation gets its own scrollback. Adapters that
don't support threads (or fail) return None and the watcher
falls back to the home channel directly.
3. Constructs a SessionSource keyed as 'thread' when a thread was
created, 'dm' otherwise, then session_store.switch_session
re-binds the destination key to the CLI session_id. The full
role-aware transcript replays via load_transcript on the next
turn (no flat-text injection into context_prompt).
4. Forges a synthetic MessageEvent(internal=True) with the handoff
notice and dispatches through _handle_message; the agent runs
against the loaded transcript and adapter.send delivers the
reply.
5. Marks the row 'completed' on success, 'failed' (+error) on any
exception.
Adapter capability (gateway/platforms/base.py): create_handoff_thread
default returns None. Three overrides:
- Telegram (gateway/platforms/telegram.py): wraps _create_dm_topic
so DM topics (Bot API 9.4+) and forum supergroups both work.
- Discord (gateway/platforms/discord.py): parent.create_thread on
text channels with a seed-message + message.create_thread
fallback for permission edge cases. Skips DMs and other
non-thread-capable parents.
- Slack (gateway/platforms/slack.py): posts a seed message and
returns its ts as the thread anchor — Slack threads are
message-anchored.
In thread mode, build_session_key keys the destination without
user_id (thread_sessions_per_user defaults to False) so the synthetic
turn and any later real-user message in the thread share the same
session_key — seamless takeover without race.
CommandDef stays cli_only=True (handoff is initiated from the CLI;
gateway exposes /resume for the reverse direction).
Removed the original PR's _handle_message_with_agent handoff hook
(transcript-as-text injection into context_prompt) and the
send_message_tool notification — both replaced by the watcher path.
Tests rewritten around the new state machine: 13/13 pass.
E2E-validated thread + no-thread paths and the failure path against
real worktree imports with mocked adapters.
Adds /handoff <platform> CLI command that queues the current session for
resume on the configured home channel of any messaging platform.
CLI side:
- /handoff telegram — marks session in shared DB, sends summary to
the Telegram home channel via send_message
- /handoff discord — same for Discord
- Supports telegram, discord, slack, whatsapp, signal, matrix
Gateway side:
- On new session creation, checks for pending handoffs for the
incoming message's platform
- If found, loads the CLI session's full conversation history and
injects it into the context prompt as a handoff transcript
- Agent continues the conversation seamlessly

- cli.py: _handle_handoff_command dispatch + handler

Subagent stream drops were spamming the parent terminal with two lines
per blip ('Connection dropped...' + 'Reconnected...') while leaving zero
breadcrumb in agent.log to debug them.
Two underlying bugs, fixed together:
1. quiet_mode raised the run_agent/tools/etc. loggers to ERROR, which
filters records before root-logger file handlers see them. The comment
claimed 'File handlers still capture everything' — that was wrong.
Removed in both run_agent.py and cli.py; console quietness already
comes from hermes_logging not installing a console StreamHandler in
non-verbose mode.
2. The stream-retry blocks emitted two _emit_status calls per drop
('⚠️ Connection dropped... Reconnecting...' + '🔄 Reconnected —
resuming…') with no provider name, so multi-provider sessions had to
dig through agent.log to attribute a drop. Replaced both call sites
with a single _emit_stream_drop helper that emits ONE line naming the
provider and error class, and always writes a structured WARNING to
agent.log with subagent_id, depth, provider, base_url, error_type.
Net UX change: 6 lines per triple-subagent drop → 3 lines, each
naming the provider. agent.log now has a structured breadcrumb per
retry that didn't exist before.
Tests: 6 new tests in tests/run_agent/test_stream_drop_logging.py
covering the logger-level guard, structured WARNING content, single
status line per drop (no Reconnected follow-up), and provider naming.
`hermes chat -q "..."` printed the full welcome banner before
running the query — kawaii ASCII logo, available toolsets list,
available skills list, model name, session ID, working directory,
update-available notice. Building it took ~420 ms on cold start
(~200 ms version-update probe, the rest is toolset / skill enumeration
plus Rich panel rendering).
For a one-shot `-q` query the banner is noise: the user already
picked the prompt, doesn't need a toolset reference, and gets the
session ID + resume hint from `_print_exit_summary()` after the
response prints.
The fully-quiet `-Q` / `--quiet` machine-readable path was already
banner-free; this brings the human-facing single-query path in line
so all non-interactive invocations are fast.
Measured impact (`hermes chat -q "ok" --max-turns 1`, 10-run
percentiles, 9950X3D):
median: 1.90 → 1.75 s (-150 ms)
min: 1.80 → 1.73 s ( -70 ms)
P25: 1.82 → 1.74 s ( -80 ms)
Wider variance than expected; the banner cost overlaps with API
latency on real `chat -q` runs. Min-time delta of 70 ms is the
cleanest signal — that's the deterministic banner-build cost gone.
The 150 ms median delta picks up cases where the version-update
probe also finishes during the wait.
Interactive mode (`hermes` with no `-q`) and the `--list-tools` /
`--list-toolsets` one-shot listing commands still show the banner —
those are the contexts where it's actually wanted.
Tests: 656/656 `tests/cli/` pass on top of latest main (modulo 5 pre-
existing flakes in `test_cli_save_config_value.py` that fail with
`No module named 'ruamel'` both with and without this change).
Problem: terminal.docker_env set in config.yaml was silently ignored.
Docker containers never received the user-specified env vars.
Root cause: docker_env was missing from all three config→env bridging
maps (cli.py env_mappings, gateway/run.py _terminal_env_map,
hermes_cli/config.py _config_to_env_sync) and from the terminal_tool
_get_env_config() reader. _create_environment() consumed the key from
container_config correctly, but it was always {} because TERMINAL_DOCKER_ENV
was never set.
Also extend the list-serialisation branches in cli.py and gateway/run.py
to handle dict values via json.dumps (lists already used json.dumps;
plain str() on a dict produces undecodable output).
Fix:
- cli.py: add "docker_env": "TERMINAL_DOCKER_ENV" to env_mappings;
serialise dict values with json.dumps alongside existing list path
- gateway/run.py: same additions to _terminal_env_map and serialisation
- hermes_cli/config.py: add "terminal.docker_env": "TERMINAL_DOCKER_ENV"
to _config_to_env_sync so `hermes config set terminal.docker_env …`
persists to .env correctly
- tools/terminal_tool.py: add docker_env key to _get_env_config() reading
TERMINAL_DOCKER_ENV via _parse_env_var with default "{}"
Tests: add test_docker_env_is_bridged_everywhere to
tests/tools/test_terminal_config_env_sync.py — stash-verified: fails on
origin/main, passes with fix.
Fixes#20537
Pick openrouter/pareto-code as your model and OpenRouter auto-routes each
request to the cheapest model meeting your coding-quality bar (ranked by
Artificial Analysis). The new openrouter.min_coding_score config key (0.0-1.0,
default 0.65) tunes the floor.
- hermes_cli/models.py: add openrouter/pareto-code to OPENROUTER_MODELS so
it shows up in the picker with a description
- hermes_cli/config.py: add openrouter.min_coding_score (default 0.65 — lands
on a mid-tier coder on the current Pareto frontier)
- plugins/model-providers/openrouter: emit extra_body.plugins =
[{id: pareto-router, min_coding_score: X}] when model is openrouter/pareto-code
AND the score is a valid float in [0.0, 1.0]
- agent/transports/chat_completions.py: same emission on the legacy flag
path (when no provider profile is loaded)
- run_agent.py: openrouter_min_coding_score kwarg + storage; plumbed into
both build_kwargs() invocations and the context-summary extra_body path
- cli.py: read openrouter.min_coding_score once at init, validate float in
[0,1], pass to AIAgent constructions (CLI + background-task paths)
- cron/scheduler.py, batch_runner.py, tools/delegate_tool.py,
tui_gateway/server.py: propagate the kwarg (mirrors providers_order
plumbing — subagents inherit, cron/batch read from config)
- tests: profile-level + transport-level coverage of the model gating,
unset/empty/out-of-range handling, and the legacy flag path
- docs: new 'OpenRouter Pareto Code Router' section in providers.md
Verified end-to-end against api.openrouter.ai: at score=0.65 we land on a
mid-tier coder, at omission we get the strongest. Score is silently dropped
on any model other than openrouter/pareto-code, so it's safe to leave set.
Native Windows, WSL, SSH sessions, and Windows Terminal all send
Ctrl+Enter as bare LF (c-j). Hermes was binding c-j as submit on
every POSIX platform, so Ctrl+Enter submitted instead of inserting
a newline on those terminals. Reported in #22379.
Add _preserve_ctrl_enter_newline() predicate that detects the
environments where Ctrl+Enter must produce a newline (sys.platform
== 'win32', SSH_CONNECTION/SSH_CLIENT/SSH_TTY env, WT_SESSION,
WSL_DISTRO_NAME, /proc/version 'microsoft' marker). Gate the
c-j-as-submit binding off in those environments and gate the
c-j-as-newline handler on. Local POSIX TTYs without those markers
(docker exec, plain ssh from a Mac) keep c-j as submit so plain
Enter still works on thin PTYs.
Add install_ctrl_enter_alias() in hermes_cli/pt_input_extras.py
mapping the three CSI-u / modifyOtherKeys variants of Ctrl+Enter
('\x1b[13;5u', '\x1b[27;5;13~', '\x1b[27;5;13u') to the
(Escape, ControlM) tuple Alt+Enter produces. This lets Kitty /
mintty / xterm-with-modifyOtherKeys users over SSH get a Ctrl+Enter
newline through the existing Alt+Enter handler.
9 new tests + extended existing test_lf_enter_binds_to_submit_handler_posix
to cover bare-local vs SSH branches.
Closes#22379.
/clear, /new, /reset, and /undo now ask the user to confirm before
discarding conversation state — three-option prompt routed through the
existing tools.slash_confirm primitive.
Native yes/no buttons render on Telegram, Discord, and Slack (their
adapters already implement send_slash_confirm); other platforms get a
text-fallback prompt and reply with /approve, /always, or /cancel.
The classic prompt_toolkit CLI uses the same three-option flow via the
established _prompt_text_input pattern (see _confirm_and_reload_mcp).
TUI keeps its existing modal overlay (#12312).
Gated by new config key approvals.destructive_slash_confirm (default
true). Picking 'Always Approve' flips the gate to false so subsequent
destructive commands run silently — matches the established
mcp_reload_confirm UX.
Out of scope: /cron remove (separate domain — scheduled jobs, not
session history). Existing TUI overlay env-var (HERMES_TUI_NO_CONFIRM)
left unchanged; cosmetic unification can come later.
Closes#4069.
SQLite's WAL mode requires shared-memory (mmap) coordination and fcntl
byte-range locks that don't reliably work on network filesystems. Upstream
documents this explicitly:
https://www.sqlite.org/wal.html#sometimes_queries_return_sqlite_busy_in_wal_mode
On NFS / SMB / some FUSE mounts / WSL1, 'PRAGMA journal_mode=WAL' raises
'sqlite3.OperationalError: locking protocol' (SQLITE_PROTOCOL). Before
this change, every feature backed by state.db or kanban.db broke silently:
- /resume, /title, /history, /branch returned 'Session database not
available.' with no cause
- gateway logged the init failure at DEBUG (invisible in errors.log)
- kanban dispatcher crashed every 60s, driving the known migration race
(duplicate column name: consecutive_failures, #21708 / #21374)
Changes:
- hermes_state.apply_wal_with_fallback(): shared helper that tries WAL
and falls back to DELETE on SQLITE_PROTOCOL-style errors with one
WARNING explaining why
- hermes_state.get_last_init_error() + format_session_db_unavailable():
capture the init failure cause and surface it in user-facing strings
(with an NFS/SMB pointer for 'locking protocol')
- hermes_cli/kanban_db.connect(): use the shared helper
- gateway/run.py: bump SessionDB init failure log DEBUG -> WARNING
(matches cli.py's existing correct behavior)
- cli.py (4 sites) + gateway/run.py (5 sites): replace bare
'Session database not available.' with format_session_db_unavailable()
Tests: 12 new tests in tests/test_hermes_state_wal_fallback.py + 1 new
test in tests/hermes_cli/test_kanban_db.py. Existing suites (state,
kanban, gateway, cli) remain green for all tests unrelated to pre-existing
failures on main.
Evidence: real-world user on NFSv3 mount (172.26.224.200:d2dfac12/home,
local_lock=none) reporting 'Session database not available.' on /resume;
'locking protocol' appears in 4 distinct log entries across backup,
kanban, TUI, and CLI paths in the same session.
closes#22032
Closes#5346.
Most terminals send the same byte sequence for `Enter` and `Shift+Enter`
by default, so the application can't tell them apart — this is a terminal
protocol limitation, not something Hermes can paper over. But terminals
that implement the Kitty keyboard protocol (Kitty / foot / WezTerm /
Ghostty by default; iTerm2 / Alacritty / VS Code terminal / Warp once the
protocol is enabled) DO emit a distinct sequence for `Shift+Enter`:
- `\x1b[13;2u` — Kitty / CSI-u, modifier=2
- `\x1b[27;2;13~` — xterm modifyOtherKeys=2
Stock prompt_toolkit doesn't have the CSI-u sequence in its
`ANSI_SEQUENCES` table at all, and it maps the modifyOtherKeys variant to
plain `Keys.ControlM` (Enter) — i.e. it strips the Shift modifier, which
is the bug users actually hit on iTerm2 and friends.
This PR adds `hermes_cli/pt_input_extras.install_shift_enter_alias()`,
called once at CLI startup from `cli.py`, which inserts/overwrites those
sequences in `ANSI_SEQUENCES` so they decode to `(Keys.Escape, Keys.ControlM)`
— the same key tuple `Alt+Enter` produces. The existing Alt+Enter newline
handler (`@kb.add('escape', 'enter')` in `cli.py`) then fires unchanged,
so there is no new keybinding to register and no behavioral change for
terminals that don't emit the distinct sequences.

=====
* `hermes_cli/pt_input_extras.py` — new module hosting the helper. Lives
outside `cli.py` so it's importable in tests without dragging in the
full CLI runtime (which depends on `fire`, `rich`, etc.).
* `cli.py` — calls `install_shift_enter_alias()` once at module import.
Wrapped in try/except so prompt_toolkit version drift can't break CLI
startup.
* `tests/cli/test_cli_shift_enter_newline.py` — 6 tests:
- registration of all three byte sequences
- overwrite of stock prompt_toolkit's broken modifyOtherKeys mapping
- idempotency
- parser equivalence: CSI-u Shift+Enter == Alt+Enter
- parser equivalence: modifyOtherKeys Shift+Enter == Alt+Enter
- plain Enter remains a single key (submit), distinct from the two-key
Alt+Enter / Shift+Enter tuple
* `website/docs/user-guide/cli.md` — keybinding table updated; new
"Shift+Enter compatibility" subsection with a per-terminal status table
noting macOS Terminal / stock Windows Terminal cannot distinguish the
keystroke at the protocol level.
* `website/docs/getting-started/quickstart.md`,
`website/docs/guides/tips.md` — short mention pointing readers at the
full compatibility note in `cli.md`.

pytest tests/cli/test_cli_shift_enter_newline.py # 6 passed
Live-tested by triggering `\x1b[13;2u` against the running Vt100Parser
(see test). Not exercised in a real terminal end-to-end because that
requires a Kitty-protocol-capable host; the test exercises the parser
path that drives the live terminal too.
teknium1 hit ModuleNotFoundError: No module named 'hermes_bootstrap' after
a code update, on both his Windows machine AND his Linux workstation. The
failure mode is real and affects every user who updates hermes by any path
OTHER than a fully-successful ``hermes update``.
## What happens
hermes_bootstrap.py is a top-level module registered via pyproject.toml's
``py-modules`` list (added by Brooklyn's Windows UTF-8 stdio work). It
must be registered in the venv's editable-install .pth file before Python
can find it as a bare ``import hermes_bootstrap``.
``hermes update`` handles this correctly: (1) git reset --hard, (2) clear
__pycache__, (3) uv pip install -e . (re-registers the package including
the new py-modules list), (4) restart.
BUT if any step AFTER (1) fails — network blip during pip install, PEP 668
on a system Python, venv locked, uv not in PATH, a crash mid-update — the
user is left with new code that references hermes_bootstrap and a venv
that doesn't know about it. Every hermes invocation after that crashes
with ModuleNotFoundError, including ``hermes update`` itself. No recovery
path without manual `uv pip install -e .`.
Also affects users who ``git pull`` the repo directly without running
hermes update — relatively common for developers.
## Fix
Wrap ``import hermes_bootstrap`` in a try/except ModuleNotFoundError
across all 6 entry points (hermes_cli/main, run_agent, gateway/run,
acp_adapter/entry, cli, batch_runner). On Windows, missing bootstrap
means the UTF-8 stdio setup doesn't run — degraded behavior (Unicode
chars may fail to print) but NOT a crash. POSIX is unaffected either way
since the bootstrap is a no-op there.
Once hermes is running again, the user can ``hermes update`` to fully
recover.
## Test update
tests/test_hermes_bootstrap.py::test_entry_point_imports_bootstrap
scans for the first top-level import in each entry point and asserts it
is hermes_bootstrap. Extended the check to accept a Try block whose body
is a lone Import of hermes_bootstrap — that's the recovery-friendly form
we just introduced.
Verified behavior by ``mv hermes_bootstrap.py hermes_bootstrap.py.bak``
and confirming ``python -c "import hermes_cli.main"`` succeeds. 82/82
tests pass (hermes_bootstrap + windows-native + windows-compat).
Three related Windows-only fixes that together make the browser toolset
actually usable on Windows. Symptom chain: user invokes browser_navigate
-> tool returns {"success": false, "error": "Daemon process exited
during startup with no error output"} and the CLI exits mid-turn with
the session summary.
Root cause (3 layers):
1. tools/browser_tool.py::_find_agent_browser() resolved
node_modules/.bin/agent-browser to the extensionless POSIX shell
shim via Path.exists(). On Windows, CreateProcessW cannot execute
that script (WinError 193 "not a valid Win32 application"). Fix:
delegate to shutil.which with path=node_modules/.bin so PATHEXT
picks up agent-browser.CMD on Windows and the extensionless shim
stays correct on POSIX.
2. Windows Terminal / Win32 delivers a spurious CTRL_C_EVENT to the
parent hermes.exe whenever a background thread spawns a .cmd
subprocess. Python 3.11's default SIGINT handler raises
KeyboardInterrupt in MainThread, which unwinds prompt_toolkit's
app.run() -> cli.py::run()'s finally block calls _run_cleanup()
-> _emergency_cleanup_all_sessions -> spawns a concurrent
_run_browser_command("close", ...) on the same session the agent
thread just opened. Two agent-browser processes race on the same
--session name, the daemon startup loses, and the tool returns
the "Daemon process exited during startup" error. Fix: install a
Windows-only SIGINT handler that absorbs the signal silently.
Real user Ctrl+C still routes through prompt_toolkit's own c-c
keybinding at the TUI layer, which is how Claude Code handles the
same quirk (driving cancellation via the TUI key handler, not
signals).
3. In tools/browser_tool.py, both Popen sites now pass
creationflags=CREATE_NO_WINDOW | STARTF_USESTDHANDLES with
close_fds=True on Windows. CREATE_NO_WINDOW suppresses the .cmd
console flash; STARTF_USESTDHANDLES + close_fds ensures the child
inherits only our three chosen handles (DEVNULL stdin, temp-file
stdout/stderr) and no leaked parent console handles that could
confuse agent-browser's native daemon spawn. Notably we do NOT
add CREATE_NEW_PROCESS_GROUP - on Python 3.11 Windows the flag
interacts badly with asyncio's ProactorEventLoop and makes things
worse.
Verified end-to-end on Windows 10 / Windows Terminal / PowerShell:
browser_navigate to https://example.com returns
{"success": true, "title": "Example Domain"} and the CLI stays alive
for follow-up tool calls and assistant turns.
Refs: earlier Windows quirks commits 1cebb3bad (Ctrl+Enter newline),
26f5af52a (environment hints), aefd1a37f (Playwright Chromium).
Windows Terminal intercepts Alt+Enter for its fullscreen shortcut, leaving
Windows users with no Enter-involving way to insert a newline in the Hermes
prompt. Fix it by reclaiming c-j on Windows only:
- _bind_prompt_submit_keys now binds c-j (LF) to submit only on POSIX, where
thin PTYs (docker exec, some SSH configs) deliver Enter as LF. On Windows
plain Enter is always c-m, so c-j is free.
- Windows-only prompt binding: c-j inserts a newline. Windows Terminal sends
Ctrl+Enter as LF, so the user-facing keystroke is Ctrl+Enter — no terminal
settings changes required.
- Alt+Enter binding unchanged; still works on mac/Linux/WSL.
- Test TestPromptToolkitTerminalCompatibility::test_lf_enter_binds_to_submit_handler
split into platform-aware assertions for POSIX vs win32.
- Fixed the Ctrl+J claim in hermes_cli/tips.py (was wrong before this commit
even on POSIX) to point Windows users at Ctrl+Enter.
Tradeoff: on Windows, raw Ctrl+J (without Enter) also inserts a newline,
since WT collapses Ctrl+Enter and Ctrl+J to the same c-j keycode. No
conflicting Hermes binding existed for Ctrl+J, so this is a harmless side
effect.
Closes the last Python-on-Windows UTF-8 exposure by making every
text-mode open() call explicit about its encoding.
Before: on Windows, bare open(path, 'r') defaults to the system
locale encoding (cp1252 on US-locale installs). That means reading
any config/yaml/markdown/json file with non-ASCII content either
crashes with UnicodeDecodeError or silently mis-decodes bytes.
After: all 89 affected call sites in production code now pass
encoding='utf-8' explicitly. Works identically on every platform
and every locale, no surprise behavior.
Mechanical sweep via:
ruff check --preview --extend-select PLW1514 --unsafe-fixes --fix --exclude 'tests,venv,.venv,node_modules,website,optional-skills, skills,tinker-atropos,plugins' .
All 89 fixes have the same shape: open(x) or open(x, mode) became
open(x, encoding='utf-8') or open(x, mode, encoding='utf-8'). Nothing
else changed. Every modified file still parses and the Windows/sandbox
test suite is still green (85 passed, 14 skipped, 0 failed across
tests/tools/test_code_execution_windows_env.py +
tests/tools/test_code_execution_modes.py + tests/tools/test_env_passthrough.py +
tests/test_hermes_bootstrap.py).
Scope notes:
- tests/ excluded: test fixtures can use locale encoding intentionally
(exercising edge cases). If we want to tighten tests later that's
a separate PR.
- plugins/ excluded: plugin-specific conventions may differ; plugin
authors own their code.
- optional-skills/ and skills/ excluded: skill scripts are user-authored
and we don't want to mass-edit them.
- website/ and tinker-atropos/ excluded: vendored / generated content.
46 files touched, 89 +/- lines (symmetric replacement). No behavior
change on POSIX or on Windows when the file is ASCII; bug fix on
Windows when the file contains non-ASCII.
Codebase-wide fix for Python-on-Windows UTF-8 footguns, complementing
the earlier execute_code sandbox fixes (which remain load-bearing for
when the sandbox explicitly scrubs child env).
Problem: Python on Windows has two long-standing text-encoding pitfalls:
1. sys.stdout/stderr are bound to the console code page (cp1252 on
US-locale installs) — print('café') crashes with UnicodeEncodeError.
2. Subprocess children don't know to use UTF-8 unless PYTHONUTF8 and/or
PYTHONIOENCODING are set in their env — so any Python we spawn
(linters, sandbox children, delegation workers) hits the same bug.
Solution: A tiny bootstrap module (hermes_bootstrap.py) imported as the
first statement of every Hermes entry point:
- hermes_cli/main.py (hermes / hermes-agent console_script)
- run_agent.py (hermes-agent direct)
- acp_adapter/entry.py (hermes-acp)
- gateway/run.py (messaging gateway)
- batch_runner.py (parallel batch mode)
- cli.py (legacy direct-launch CLI)
On Windows, the bootstrap:
- os.environ.setdefault('PYTHONUTF8', '1') (PEP 540 UTF-8 mode)
- os.environ.setdefault('PYTHONIOENCODING', 'utf-8')
- sys.stdout/stderr/stdin.reconfigure(encoding='utf-8', errors='replace')
Children inherit the env vars → they run in UTF-8 mode.
Current process's stdio is reconfigured → print('café') works now.
On POSIX (Linux/macOS), the bootstrap is a complete no-op. We don't
touch LANG, LC_*, or anything else — users who have intentionally
configured a non-UTF-8 locale aren't affected. POSIX systems are
already UTF-8 by default in 99% of modern setups, so there's nothing
to fix.
setdefault() (not overwrite) means users who explicitly set PYTHONUTF8=0
or PYTHONIOENCODING=cp1252 in their environment are respected.
What this does NOT fix: bare open(path, 'w') calls in the *parent*
process still default to locale encoding because PYTHONUTF8 is only
read at interpreter init. A ruff PLW1514 sweep (separate follow-up)
will add explicit encoding='utf-8' at those ~219 call sites for
belt-and-suspenders.
Tests (17): 16 passed, 1 skipped on Windows.
- Windows: env vars set, stdio reconfigured, child inherits UTF-8 mode
- POSIX: complete no-op (verified on fake POSIX + skipped on real
POSIX since we don't have a Linux box in this session)
- Idempotence: multiple calls safe
- Graceful degradation: non-reconfigurable streams don't crash
- User opt-out: explicit PYTHONUTF8=0 is respected
- Load order: every entry point's FIRST top-level import is
hermes_bootstrap, enforced by an AST-level parametrized test
pyproject.toml: added hermes_bootstrap to py-modules so it ships with
pip installs.
Second pass on native Windows support, driven by a systematic audit across
five areas: POSIX-only primitives (signal.SIGKILL/SIGHUP/SIGPIPE, os.WNOHANG,
os.setsid), path translation bugs (/c/Users → C:\Users), subprocess patterns
(npm.cmd batch shims, start_new_session no-op on Windows), subsystem health
(cron, gateway daemon, update flow), and module-level import guards.
Every change is platform-gated — POSIX (Linux/macOS) behaviour is preserved
bit-identical. Explicit "do no harm" test: test_posix_path_preserved_on_linux,
test_posix_noop, test_windows_detach_popen_kwargs_is_posix_equivalent_on_posix.
## New module
- hermes_cli/_subprocess_compat.py — shared helpers (resolve_node_command,
windows_detach_flags, windows_hide_flags, windows_detach_popen_kwargs).
All no-ops on non-Windows.
## CRITICAL fixes (would crash or silently break on Windows)
- tui_gateway/entry.py: SIGPIPE/SIGHUP referenced at module top level would
AttributeError on import on Windows, breaking `hermes --tui` entirely (it
spawns this module as a subprocess). Guard each signal.signal() call with
hasattr() and add SIGBREAK as Windows' SIGHUP equivalent.
- hermes_cli/kanban_db.py: os.waitpid(-1, os.WNOHANG) in dispatcher tick was
unguarded. os.WNOHANG doesn't exist on Windows. Gate the whole reap loop
behind `os.name != "nt"` — Windows has no zombies anyway.
- tools/code_execution_tool.py: AF_UNIX socket for execute_code RPC fails on
most Windows builds. Fall back to loopback TCP (AF_INET on 127.0.0.1:0
ephemeral port) when _IS_WINDOWS. HERMES_RPC_SOCKET env var now accepts
either a filesystem path (POSIX) or `tcp://127.0.0.1:<port>` (Windows).
Generated sandbox client parses both.
- cron/scheduler.py: `argv = ["/bin/bash", str(path)]` hardcoded. Use
shutil.which("bash") so Windows (Git Bash via MinGit) works, with a
readable error when bash is genuinely absent.
- 6 bare npm/npx spawn sites: tools_config.py x2, doctor.py, whatsapp.py
(npm install + node version probe), browser_tool.py x2. On Windows npm
is npm.cmd / npx is npx.cmd (batch shims); subprocess.Popen(["npm", ...])
fails with WinError 193. shutil.which(...) returns the absolute .cmd
path which CreateProcessW accepts because the extension routes through
cmd.exe /c. POSIX behaviour unchanged (shutil.which still returns the
same path subprocess would resolve itself).
## HIGH fixes (silent misbehaviour on Windows)
- tools/environments/local.py get_temp_dir: hardcoded /tmp returned on
Windows meant `_cwd_file = "/tmp/hermes-cwd-*.txt"`, which bash wrote
via MSYS2's virtual /tmp but native Python couldn't open. Result: cwd
tracking silently broken — `cd` in terminal tool did nothing. Windows
branch now returns `%HERMES_HOME%/cache/terminal` with forward slashes
(works in both bash and Python, guaranteed no spaces).
- tools/environments/local.py _make_run_env PATH injection: `/usr/bin not
in split(":")` heuristic mangles Windows PATH (";" separator). Gate
the injection behind `not _IS_WINDOWS`.
- hermes_cli/gateway.py launch_detached_profile_gateway_restart: outer
Popen + watcher-script Popen both used start_new_session=True, which
Windows silently ignores. Watcher stayed attached to CLI's console,
died when user closed terminal after `hermes update`, left gateway
stale. Now branches through windows_detach_popen_kwargs() helper
(CREATE_NEW_PROCESS_GROUP | DETACHED_PROCESS | CREATE_NO_WINDOW on
Windows, start_new_session=True on POSIX — identical to main).
## MEDIUM fixes
- gateway/run.py /restart and /update handlers: hardcoded bash/setsid
chain crashes on Windows when user triggers /update in-gateway. Now
has sys.platform=="win32" branch using sys.executable + a tiny
Python watcher with proper detach flags. POSIX path is unchanged.
- cli.py _git_repo_root: Git on Windows sometimes returns /c/Users/...
style paths that break subprocess.Popen(cwd=...) and Path().resolve().
Added _normalize_git_bash_path() helper that translates /c/Users,
/cygdrive/c, /mnt/c variants to native C:\Users form. POSIX no-op.
_git_repo_root() now routes every result through it.
- cli.py worktree .worktreeinclude: os.symlink on directories failed
hard on Windows (requires admin or Developer Mode). Falls back to
shutil.copytree with a warning log.
## Tests
- 29 new tests in tests/tools/test_windows_native_support.py covering:
subprocess_compat helpers, TUI entry signal guards, kanban waitpid
guard, code_execution TCP fallback source-level invariants, cron bash
resolution, npm/npx bare-spawn lint per-file, local env Windows temp
dir, PATH injection gating, git bash path normalization, symlink
fallback, gateway detached watcher flags.
- One existing test assertion adjusted in test_browser_homebrew_paths:
it compared captured Popen argv to the BARE `"npx"` literal; after the
shutil.which() change argv[0] is the absolute path. New assertion
checks the shape (two items, second is `agent-browser`) rather than
the exact first-item string. Behaviour unchanged; test was too strict.
All 56 tests pass on Linux (30 from previous commits + 26 new).
267 tests from the affected files/dirs (browser, code_exec, local_env,
process_registry, kanban_db, windows_compat) all pass — zero regressions.
tests/hermes_cli/ (3909 pass) and tests/gateway/ (5021 pass) unchanged;
all pre-existing test failures confirmed unrelated via `git stash` re-run.
## What's still deferred (LOW priority)
- Visible cmd-window flashes on short-lived console apps (~14 sites) —
cosmetic, needs a follow-up pass once we have user reports.
- agent/file_safety.py POSIX-only security deny patterns — separate
hardening task.
- tools/process_registry.py returning "/tmp" as fallback — theoretical;
reachable only when all env-var candidates fail.
Native Windows (with Git for Windows installed) can now run the Hermes CLI
and gateway end-to-end without crashing. install.ps1 already existed and
the Git Bash terminal backend was already wired up — this PR fills the
remaining gaps discovered by auditing every Windows-unsafe primitive
(`signal.SIGKILL`, `os.kill(pid, 0)` probes, bare `fcntl`/`termios`
imports) and by comparing hermes against how Claude Code, OpenCode, Codex,
and Cline handle native Windows.
## What changed
### UTF-8 stdio (new module)
- `hermes_cli/stdio.py` — single `configure_windows_stdio()` entry point.
Flips the console code page to CP_UTF8 (65001), reconfigures
`sys.stdout`/`stderr`/`stdin` to UTF-8, sets `PYTHONIOENCODING` + `PYTHONUTF8`
for subprocesses. No-op on non-Windows. Opt out via `HERMES_DISABLE_WINDOWS_UTF8=1`.
- Called early in `cli.py::main`, `hermes_cli/main.py::main`, and
`gateway/run.py::main` so Unicode banners (box-drawing, geometric
symbols, non-Latin chat text) don't `UnicodeEncodeError` on cp1252
consoles.
### Crash sites fixed
- `hermes_cli/main.py:7970` (hermes update → stuck gateway sweep): raw
`os.kill(pid, _signal.SIGKILL)` → `gateway.status.terminate_pid(pid, force=True)`
which routes through `taskkill /T /F` on Windows.
- `hermes_cli/profiles.py::_stop_gateway_process`: same fix — also
converted SIGTERM path to `terminate_pid()` and widened OSError catch
on the intermediate `os.kill(pid, 0)` probe.
- `hermes_cli/kanban_db.py:2914, 3041`: raw `signal.SIGKILL` →
`getattr(signal, "SIGKILL", signal.SIGTERM)` fallback (matches the
pattern already used in `gateway/status.py`).
### OSError widening on `os.kill(pid, 0)` probes
Windows raises `OSError` (WinError 87) for a gone PID instead of
`ProcessLookupError`. Widened the catch at:
- `gateway/run.py:15101` (`--replace` wait-for-exit loop — without this,
the loop busy-spins the full 10s every Windows gateway start)
- `hermes_cli/gateway.py:228, 460, 940`
- `hermes_cli/profiles.py:777`
- `tools/process_registry.py::_is_host_pid_alive`
- `tools/browser_tool.py:1170, 1206`
### Dashboard PTY graceful degradation
`hermes_cli/pty_bridge.py` depends on `fcntl`/`termios`/`ptyprocess`,
none of which exist on native Windows. Previously a Windows dashboard
would crash on `import hermes_cli.web_server` because of a top-level
import. Now:
- `hermes_cli/web_server.py` wraps the pty_bridge import in
`try/except ImportError` and sets `_PTY_BRIDGE_AVAILABLE=False`.
- The `/api/pty` WebSocket handler returns a friendly "use WSL2 for
this tab" message instead of exploding.
- Every other dashboard feature (sessions, jobs, metrics, config
editor) runs natively on Windows.
### Dependency
- `pyproject.toml`: add `tzdata>=2023.3; sys_platform == 'win32'` so
Python's `zoneinfo` works on Windows (which has no IANA tzdata
shipped with the OS). Credits @sprmn24 (PR #13182).
### Docs
- README.md: removed "Native Windows is not supported"; added
PowerShell one-liner and Git-for-Windows prerequisite note.
- `website/docs/getting-started/installation.md`: new Windows section
with capability matrix (everything native except the dashboard
`/chat` PTY tab, which is WSL2-only).
- `website/docs/user-guide/windows-wsl-quickstart.md`: reframed as
"WSL2 as an alternative to native" rather than "the only way".
- `website/docs/developer-guide/contributing.md`: updated
cross-platform guidance with the `signal.SIGKILL` / `OSError`
rules we enforce now.
- `website/docs/user-guide/features/web-dashboard.md`: acknowledged
native Windows works for everything except the embedded PTY pane.
## Why this shape
Pulled from a survey of how other agent codebases handle native
Windows (Claude Code, OpenCode, Codex, Cline):
- All four treat Git Bash as the canonical shell on Windows, same as
hermes already does in `tools/environments/local.py::_find_bash()`.
- None of them force `SetConsoleOutputCP` — but they don't have to,
Node/Rust write UTF-16 to the Win32 console API. Python does not get
that for free, so we flip CP_UTF8 via ctypes.
- None of them ship PowerShell-as-primary-shell (Claude Code exposes
PS as a secondary tool; scope creep for this PR).
- All of them use `taskkill /T /F` for force-kill on Windows, which
is exactly what `gateway.status.terminate_pid(force=True)` does.
## Non-goals (deliberate scope limits)
- No PowerShell-as-a-second-shell tool — worth designing separately.
- No terminal routing rewrite (#12317, #15461, #19800 cluster) — that's
the hardest design call and needs a separate doc.
- No wholesale `open()` → `open(..., encoding="utf-8")` sweep (Tianworld
cluster) — will do as follow-up if users hit actual breakage; most
modern code already specifies it.
## Validation
- 28 new tests in `tests/tools/test_windows_native_support.py` — all
platform-mocked, pass on Linux CI. Cover:
- `configure_windows_stdio` idempotency, opt-out, env-preservation
- `terminate_pid` taskkill routing, failure → OSError, FileNotFoundError fallback
- `getattr(signal, "SIGKILL", …)` fallback shape
- `_is_host_pid_alive` OSError widening (Windows-gone-PID behavior)
- Source-level checks that all entry points call `configure_windows_stdio`
- pty_bridge import-guard present in `web_server.py`
- README no longer says "not supported"
- 12 pre-existing tests in `tests/tools/test_windows_compat.py` still pass.
- `tests/hermes_cli/` ran fully (3909 passed, 9 failures — all confirmed
pre-existing on main by stash-test).
- `tests/gateway/` ran fully (5021 passed, 1 pre-existing failure).
- `tests/tools/test_process_registry.py` + `test_browser_*` pass.
- Manual smoke: `import hermes_cli.stdio; import gateway.run;
import hermes_cli.web_server` — all clean, `_PTY_BRIDGE_AVAILABLE=True`
on Linux (as expected).

Background macOS desktop control via cua-driver MCP — does NOT steal the
user's cursor or keyboard focus, works with any tool-capable model.
Replaces the Anthropic-native `computer_20251124` approach from the
abandoned #4562 with a generic OpenAI function-calling schema plus SOM
(set-of-mark) captures so Claude, GPT, Gemini, and open models can all
drive the desktop via numbered element indices.
- `tools/computer_use/` package — swappable ComputerUseBackend ABC +
CuaDriverBackend (stdio MCP client to trycua/cua's cua-driver binary).
- Universal `computer_use` tool with one schema for all providers.
Actions: capture (som/vision/ax), click, double_click, right_click,
middle_click, drag, scroll, type, key, wait, list_apps, focus_app.
- Multimodal tool-result envelope (`_multimodal=True`, OpenAI-style
`content: [text, image_url]` parts) that flows through
handle_function_call into the tool message. Anthropic adapter converts
into native `tool_result` image blocks; OpenAI-compatible providers
get the parts list directly.
- Image eviction in convert_messages_to_anthropic: only the 3 most
recent screenshots carry real image data; older ones become text
placeholders to cap per-turn token cost.
- Context compressor image pruning: old multimodal tool results have
their image parts stripped instead of being skipped.
- Image-aware token estimation: each image counts as a flat 1500 tokens
instead of its base64 char length (~1MB would have registered as
~250K tokens before).
- COMPUTER_USE_GUIDANCE system-prompt block — injected when the toolset
is active.
- Session DB persistence strips base64 from multimodal tool messages.
- Trajectory saver normalises multimodal messages to text-only.
- `hermes tools` post-setup installs cua-driver via the upstream script
and prints permission-grant instructions.
- CLI approval callback wired so destructive computer_use actions go
through the same prompt_toolkit approval dialog as terminal commands.
- Hard safety guards at the tool level: blocked type patterns
(curl|bash, sudo rm -rf, fork bomb), blocked key combos (empty trash,
force delete, lock screen, log out).
- Skill `apple/macos-computer-use/SKILL.md` — universal (model-agnostic)
workflow guide.
- Docs: `user-guide/features/computer-use.md` plus reference catalog
entries.
44 new tests in tests/tools/test_computer_use.py covering schema
shape (universal, not Anthropic-native), dispatch routing, safety
guards, multimodal envelope, Anthropic adapter conversion, screenshot
eviction, context compressor pruning, image-aware token estimation,
run_agent helpers, and universality guarantees.
469/469 pass across tests/tools/test_computer_use.py + the affected
agent/ test suites.
- `model_tools.py` provider-gating: the tool is available to every
provider. Providers without multi-part tool message support will see
text-only tool results (graceful degradation via `text_summary`).
- Anthropic server-side `clear_tool_uses_20250919` — deferred;
client-side eviction + compressor pruning cover the same cost ceiling
without a beta header.
- macOS only. cua-driver uses private SkyLight SPIs
(SLEventPostToPid, SLPSPostEventRecordTo,
_AXObserverAddNotificationAndCheckRemote) that can break on any macOS
update. Pin with HERMES_CUA_DRIVER_VERSION.
- Requires Accessibility + Screen Recording permissions — the post-setup
prints the Settings path.
Supersedes PR #4562 (pyautogui/Quartz foreground backend, Anthropic-
native schema). Credit @0xbyt4 for the original #3816 groundwork whose
context/eviction/token design is preserved here in generic form.
Reported: Ctrl+C during an active /goal loop felt like it did nothing —
the agent would interrupt the current turn, then immediately queue another
continuation and keep going until the session ended or the 20-turn budget
ran out.
Root cause: cli.py's _maybe_continue_goal_after_turn() ran in the finally:
block around self.chat(...) unconditionally. Whether the turn completed
normally, got interrupted, or returned an empty string, the judge ran on
whatever was in conversation_history and — because the judge is fail-open
— a "continue" verdict pushed another CONTINUATION_PROMPT onto
_pending_input. Ctrl+C was invisible to the hook.
Fix:
- chat() now captures result['interrupted'] onto self._last_turn_interrupted
(resets to False at entry so early-returns don't leak prior state).
- _maybe_continue_goal_after_turn() checks the flag first: on interrupt,
auto-pause via mgr.pause(reason='user-interrupted (Ctrl+C)') and print
a one-liner pointing the user at /goal resume or /goal clear. No judge
call, no continuation enqueued.
- Also added an empty-response guard that mirrors gateway/run.py's
_handle_message logic (empty reply → transient failure → skip judging
so we don't trip the consecutive-parse-failures backstop unnecessarily).
The goal stays in the DB as paused, so /goal resume recovers it after
the user has sorted out whatever made them cancel. /goal clear still
works as before for a full stop.
Tests: tests/cli/test_cli_goal_interrupt.py covers:
- interrupted turn pauses + doesn't queue + judge is NOT called
- paused goal is resumable
- empty / whitespace / missing assistant reply skips judging
- healthy turn still enqueues continuation / marks done
- chat() resets _last_turn_interrupted at entry (anti-leak guard)
All 55 existing goal tests still pass.
When switching from a custom local provider (e.g. ollama-launch) to a
cloud provider, two bugs caused the CLI to misbehave:
1. _explicit_api_key/_explicit_base_url were only updated when the switch
result had non-empty values (guarded by `if result.api_key:` etc.).
If the previous provider set these to Ollama values ("ollama",
"http://127.0.0.1:11434/v1"), those stale values leaked into the next
turn's _ensure_runtime_credentials() call and were forwarded to the
new provider's API endpoint, causing authentication/routing failures.
Fix: unconditionally write result.api_key/base_url into the explicit
fields after every successful switch. An empty string is the correct
sentinel — it tells _ensure_runtime_credentials to re-resolve from the
auth store / config rather than forwarding a stale override.
2. In AIAgent.switch_model(), `self.base_url = base_url or self.base_url`
kept the old Ollama localhost URL whenever the incoming base_url was an
empty string. For providers that use a native SDK (not an OpenAI-compat
endpoint), the caller passes base_url="" and expects the agent to clear
the field — not silently inherit Ollama's address.
Fix: only update self.base_url when base_url is truthy.
3. _handle_model_picker_selection() was called from the prompt_toolkit
Enter key binding without any exception guard. Any unexpected error
in the model-selection code path propagated through prompt_toolkit's
key-binding dispatcher and caused the entire TUI to exit — which the
user sees as "the terminal exits when I switch providers".
Fix: wrap the call in try/except and close the picker on failure.
- Add pricing entries for Claude Opus 4.5/4.6/4.7, Sonnet 4.5/4.6, and
Haiku 4.5 with updated source URLs (platform.claude.com)
- Add _normalize_anthropic_model_name() to handle dot-notation variants
(e.g. claude-opus-4.7 → claude-opus-4-7) for pricing lookups
- Fix silent token loss: ensure session row exists before UPDATE in both
run_agent.py and hermes_state.py (INSERT OR IGNORE is idempotent)
- Log token persistence failures at DEBUG level instead of swallowing
them silently — makes undercounted analytics diagnosable
- Surface reasoning tokens in CLI /usage and TUI usage panel
- Add 'reasoning' and 'cost_status' fields to TUI Usage type
When the provider rejects a request (e.g. invalid model slug like
'--provider nous --model kimi-k2.6' where the valid slug is
'moonshotai/kimi-k2.6'), run_conversation() returns
{failed: True, error: <detail>, final_response: None}. The TUI gateway
and one-shot CLI mode both dropped the error on the floor and emitted
an empty turn, so the user saw a blank response with no indication
that anything went wrong.
Mirror the interactive CLI's existing pattern (cli.py:9832): when
final_response is empty AND (failed|partial) is set AND error is
populated, surface 'Error: <detail>' as the visible text. Leaves
the None-with-no-error path and the '(empty)' sentinel path
untouched — an empty successful turn still renders empty, and
existing sentinel handlers keep owning their lane.
Reported by @counterposition in PR #20873; taking a minimal fix
rather than the broader structured-failure refactor proposed there.
Address review feedback to use the clamp emoji (��️) instead of
the plain text 'cmp' prefix for the compression count indicator.

Display the number of context compressions in the CLI status bar when
compressions > 0, helping users understand conversation compression
pressure during long sessions.
- Wide layout (>=76 cols): shows 'cmp N' between context percent and duration
- Medium layout (52-75 cols): shows 'cmp N' between percent and duration
- Narrow layout (<52 cols): omitted to save space
- Color-coded: dim for 1-4, warn for 5-9, bad for 10+
- Hidden when zero to keep the bar clean for new sessions
Closes#18564
Flip the default for HERMES_REDACT_SECRETS from off to on so the redactor
already wired into send_message_tool, logs, and tool output actually runs
on a fresh install.
- agent/redact.py: env-var default "" → "true"
- hermes_cli/config.py: DEFAULT_CONFIG security.redact_secrets True;
two config-template comments rewritten
- gateway/run.py + cli.py: startup log / banner warning when the user
has explicitly opted out, so the downgrade is visible in agent.log
and at CLI banner time
- docs/reference/environment-variables.md: description reconciled
- tests: flipped the default-pin, restructured the force=True
regression test to explicit-false instead of unset
Users who need raw credential values (redactor development) can still
opt out via security.redact_secrets: false in config.yaml or
HERMES_REDACT_SECRETS=false in .env.
Closes#17691.
Addresses #20785 (short-term output-pipeline recommendation).
When the user pastes a long slash command like \`/goal <long prose>\` into
\`hermes chat\`, the input flows into \`_detect_file_drop()\`, whose
\`starts_like_path\` prefilter accepts anything starting with \`/\` and
forwards it to \`_resolve_attachment_path()\`. That helper calls
\`Path.exists()\` which invokes \`os.stat()\`, which raises
\`OSError(errno=ENAMETOOLONG)\` — 63 on macOS, 36 on Linux — when the
candidate exceeds NAME_MAX (typically 255 bytes).
The OSError propagates up to the broad \`except Exception\` in
\`process_loop\` (cli.py:11798), gets logged at WARNING level, and the
user's input is silently dropped. From the user's POV the chat prompt
hangs — the only signal is in agent.log:
WARNING cli: process_loop unhandled error (msg may be lost):
[Errno 63] File name too long: "/goal Drive the space board..."
This affects any slash command with prose-length arguments — \`/goal\`
in particular but also \`/skill\`, \`/cron\`, custom user commands.
Fix: wrap the \`exists()\`/\`is_file()\` calls in try/except OSError so
structurally-invalid path candidates cleanly return None. The slash-
command dispatch path downstream (cli.py:11718) then handles the
input correctly.
Tests: two new regression cases in test_cli_file_drop.py cover the
original \`/goal\` reproducer and a synthetic long path. All 35 file-
drop tests pass.
Reproducer (without the fix):
python -c "from cli import _detect_file_drop;
_detect_file_drop('/goal ' + 'a'*300)"
→ OSError: [Errno 63] File name too long
Replaces the per-directory shadow-repo design with a single shared shadow
git store at ~/.hermes/checkpoints/store/. Object DB is now deduplicated
across every working directory the agent has ever touched; a dozen
worktrees of the same project cost near-zero in additional disk.
Why
---
Pre-v2 design had three compounding problems that let ~/.hermes/checkpoints/
grow to multi-GB on active machines:
1. Each working directory got its own full shadow git repo — no object
dedup across projects or across worktrees of the same project.
2. _prune() was a documented no-op: max_snapshots only limited the
/rollback listing. Loose objects accumulated forever.
3. Defaults: enabled=True, auto_prune=False — users paid the disk cost
without ever asking for /rollback.
Field report on a single workstation: 847 MB across 47 shadow repos,
mostly redundant clones of the hermes-agent source tree.
Changes
-------
- tools/checkpoint_manager.py: full rewrite. Single bare store, per-project
refs (refs/hermes/<hash>), per-project indexes (store/indexes/<hash>),
per-project metadata (store/projects/<hash>.json with workdir +
created_at + last_touch). On first v2 init, any pre-v2 per-directory
shadow repos are auto-migrated into legacy-<timestamp>/ so the new
store starts clean. _prune() now actually rewrites the per-project ref
to the last max_snapshots commits and runs git gc --prune=now. New
_enforce_size_cap() drops oldest commits round-robin across projects
when the store exceeds max_total_size_mb. _drop_oversize_from_index()
filters any single file larger than max_file_size_mb out of the snapshot.
- hermes_cli/checkpoints.py: new 'hermes checkpoints' CLI
(status / list / prune / clear / clear-legacy) for managing the store
outside a session.
- hermes_cli/config.py: flipped defaults — enabled=False, max_snapshots=20,
auto_prune=True. Added max_total_size_mb=500, max_file_size_mb=10.
Tightened DEFAULT_EXCLUDES (added target/, *.so/*.dylib/*.dll,
*.mp4/*.mov, *.zip/*.tar.gz, .worktrees/, .mypy_cache/, etc.).
- run_agent.py / cli.py / gateway/run.py: thread the new kwargs through
AIAgent and the startup auto_prune hooks.
- Tests rewritten to match v2 storage while keeping backwards-compat
coverage for the pre-v2 prune path (per-directory shadow repos under
base/ are still swept correctly for anyone mid-migration).
- Docs updated: user-guide/checkpoints-and-rollback.md explains the
shared store, new defaults, migration, and the new CLI;
reference/cli-commands.md documents 'hermes checkpoints'.
E2E validated
-------------
- Legacy migration: pre-v2 shadow repos auto-archived into legacy-<ts>/.
- Object dedup: two projects with an identical shared.py blob resolve to
7 total objects in the store (v1 would have stored the blob twice).
- max_snapshots=3 actually enforced: after 6 commits, list shows 3.
- Orphan prune: deleting a project's workdir + 'hermes checkpoints prune
--retention-days 0' removes its ref, index, and metadata; GC reclaims
the objects.
- max_file_size_mb=1 excludes a 2 MB weights.bin while keeping the
tracked source code files.
- hermes checkpoints {status,prune,clear,clear-legacy} all work from the
CLI without an agent running.
Breaking / migration
--------------------
No in-place data migration — legacy per-directory shadow repos are moved
into legacy-<timestamp>/ on first run. Old /rollback history is still
accessible by inspecting the archive with git; run
'hermes checkpoints clear-legacy' to reclaim the space when ready. Users
relying on /rollback must now set checkpoints.enabled=true (or pass
--checkpoints) explicitly.
CPython's logging module is not reentrant-safe. `Logger.isEnabledFor`
caches level results in `Logger._cache`; under shutdown races the cache
can be cleared (`Logger._clear_cache`, triggered by logging config changes
from another thread) or mid-mutation when a signal fires, raising
`KeyError: <level_int>` (e.g. `KeyError: 10` for DEBUG) inside the signal
handler.
When that happens, the KeyError escapes before the `raise KeyboardInterrupt()`
on the next line can fire, which bypasses prompt_toolkit's normal interrupt
unwind and surfaces as the EIO cascade originally reported in #13710.
Issue #13710 shipped two defenses (asyncio exception handler + outer
`except (KeyError, OSError)` with EIO suppression) that cover the EIO
unwind path. This patch closes the remaining escape hatch: the
`logger.debug` call at the top of `_signal_handler` itself. Wrap it in a
bare `try/except Exception: pass` so logging can never raise through a
signal handler.
Observed in the wild: debug report on 0.12.0 (commit 8163d371) shows the
exact stack — KeyError: 10 at logging/__init__.py:1742 inside the
signal handler's `logger.debug`, followed by the EIO cascade from
prompt_toolkit's emergency flush.
Tests: adds `TestSignalHandlerLoggingRace` to
`tests/hermes_cli/test_suppress_eio_on_interrupt.py` with 6 new cases:
- normal path still raises KeyboardInterrupt
- KeyError(10) from logger.debug does not escape
- any Exception from logger.debug is swallowed
- agent.interrupt still fires when logger.debug raises
- agent.interrupt raising also does not escape
- BaseException (SystemExit) is NOT swallowed — guard uses `except Exception`
deliberately so real shutdown signals still propagate
Closes#13710 regression.
Add Lightpanda as an optional browser engine for local mode.
Lightpanda is a headless browser built from scratch in Zig -- faster
navigation than Chrome with significantly less memory.
One config line to enable:
browser:
engine: lightpanda
New functions in browser_tool.py:
- _get_browser_engine() -- config/env reader with validation + caching
- _should_inject_engine() -- only inject in local non-cloud mode
- _needs_lightpanda_fallback() -- detect empty/failed LP results
- _chrome_fallback_screenshot() -- temporary Chrome session for screenshots
- Engine injection in _run_browser_command (--engine flag)
- browser_vision pre-routes screenshots to Chrome when engine=lightpanda
Config:
- browser.engine in DEFAULT_CONFIG (auto/lightpanda/chrome)
- AGENT_BROWSER_ENGINE in OPTIONAL_ENV_VARS
- /browser status shows engine info in local mode
Rebased from PR #7144 onto current main. All existing code preserved --
pure additions only (+520/-2).
25 new tests + 81 total browser tests pass (0 failures).
Fix three regressions introduced by PR #18370 (lazy session creation):
1. _finalize_session() uses stale session_key after compression (#20001)
2. session_key not synced after auto-compression in run_conversation (#20001)
3. pending_title ValueError leaves title wedged forever (#19029)
4. Gateway silently swallows null responses when agent did work (#18765)
5. One-time cleanup for accumulated ghost compression continuations (#20001)
Changes:
- tui_gateway/server.py: _finalize_session() now uses agent.session_id
(falls back to session_key when agent is None). Refactor
_sync_session_key_after_compress() with clear_pending_title and
restart_slash_worker policy flags. Call it post-run_conversation()
to sync session_key after auto-compression. Add ValueError handler
to pending_title flush.
- gateway/run.py: Extract _normalize_empty_agent_response() helper that
consolidates failed/partial/null response handling. Surfaces user-facing
error when agent did work (api_calls > 0) but returned no text.
- hermes_state.py: Add finalize_orphaned_compression_sessions() — marks
ghost continuation sessions as ended (non-destructive, preserves data).
- cli.py: One-time startup migration for orphaned compression sessions.
Test changes:
- tests/test_tui_gateway_server.py: Update pending_title ValueError test
for post-#18370 architecture (title applied post-message, not at create).
- tests/test_lazy_session_regressions.py: 14 new regression tests covering
all fixed paths.
* fix(tui): respect voice.record_key config instead of hardcoded Ctrl+B
Classic CLI loaded ``voice.record_key`` from config.yaml and bound the
prompt-toolkit handler dynamically (``cli.py`` paths). The new TUI hard-
coded ``Ctrl+B`` everywhere — ``isVoiceToggleKey`` (input handler),
``/voice status`` ("Record key: Ctrl+B"), and ``/voice on`` ("Ctrl+B to
start/stop recording"). A user who set ``voice.record_key: ctrl+o``
(or any other key) saw the documented config silently ignored — only
Ctrl+B worked, the displayed shortcut lied about it.
Wire the configured key end to end through the existing channels:
* **Backend** (``tui_gateway/server.py``): ``voice.toggle`` action=status
AND action=on/off responses now include ``record_key``, sourced from
``config.get('voice', {}).get('record_key', 'ctrl+b')``.
* **Backend types** (``ui-tui/src/gatewayTypes.ts``): ``ConfigFullResponse``
now exposes ``config.voice.record_key`` and ``VoiceToggleResponse``
carries ``record_key`` so the TUI can both bind and display it.
* **Frontend parser/formatter** (``ui-tui/src/lib/platform.ts``):
``parseVoiceRecordKey()`` accepts ``ctrl+b`` / ``alt+r`` / ``cmd+space``
and the common aliases (``option``, ``cmd``, ``win``, …); falls back to
the documented Ctrl+B for empty / multi-character / malformed input so
a typo never silently disables the shortcut. ``formatVoiceRecordKey()``
renders for status text. ``isVoiceToggleKey`` now takes a parsed
``ParsedVoiceRecordKey`` argument; the hardcoded ``ch === 'b'`` is
gone. Default arg keeps existing call sites back-compat.
* **Hydration** (``ui-tui/src/app/useConfigSync.ts``,
``useMainApp.ts``): startup ``config.get full`` already runs; extract
``cfg.voice.record_key`` from it, parse, push into a new
``voiceRecordKey`` state, and forward to the input handler ctx
(``InputHandlerContext.voice.recordKey``). Mtime-poll path also
re-applies the parsed key so a hand-edit of config.yaml takes effect
the next tick — matches existing behaviour for display options.
* **Input handler** (``ui-tui/src/app/useInputHandlers.ts``):
``isVoiceToggleKey(key, ch, voice.recordKey)`` so the configured
binding fires.
* **Slash command** (``ui-tui/src/app/slash/commands/session.ts``):
``/voice status`` and ``/voice on`` use ``formatVoiceRecordKey`` on
the response's ``record_key`` instead of the hardcoded label.
Tests:
* ``parseVoiceRecordKey`` covers ctrl/alt/cmd/super aliases, multi-char
rejection, and empty fallback.
* ``formatVoiceRecordKey`` covers the doc examples (``Ctrl+B``,
``Ctrl+O``, ``Alt+R``, ``Cmd+B``).
* ``isVoiceToggleKey`` regression: ``ctrl+o`` configured → only ``o``
matches, not ``b``; ``alt+r`` matches both alt-bit and meta-bit
encodings (terminal protocol parity); omitted-arg call still binds
Ctrl+B for back-compat.
Full TUI suite (555 tests) passes; ``tsc --noEmit`` clean.
Fixes#18994

* fix(tui): support named-key tokens in voice.record_key (space, enter, …)
Reviewer caught that the round-1 parser in #18994 rejected every
multi-character token, so a config value like ``ctrl+space`` (which the
CLI happily binds via prompt_toolkit's ``c-space`` rewrite in
``cli.py``) silently fell back to the documented Ctrl+B default —
re-introducing the same false-shortcut bug the PR was meant to fix,
just at a different surface.
Add explicit named-key support that mirrors what the CLI accepts:
* ``space`` (alias: ``spc``) → matches ``ch === ' '``
* ``enter`` (alias: ``return``, ``ret``) → matches ``key.return``
* ``tab`` → matches ``key.tab``
* ``escape`` (alias: ``esc``) → matches ``key.escape``
* ``backspace`` (alias: ``bs``) → matches ``key.backspace``
* ``delete`` (alias: ``del``) → matches ``key.delete``
``ParsedVoiceRecordKey`` gains an optional ``named`` field; ``ch``
holds either a single char (back-compat) or the canonical named token,
and the runtime matcher dispatches on ``named`` before checking the
modifier shape. Aliases collapse to one canonical name so
``ctrl+esc`` and ``ctrl+escape`` behave identically.
Unrecognised multi-character tokens (e.g. ``ctrl+spcae`` typo, or
unsupported keys like ``ctrl+f5``) still fall back to the Ctrl+B
default rather than silently disabling the binding — keeps the "typo
never silently kills the shortcut" guarantee.
Tests:
* ``parseVoiceRecordKey`` parametrised over every named token + each
alias variant.
* New ``isVoiceToggleKey`` cases for space (ch-based match), enter
(``key.return``), tab, escape, backspace, delete, including
modifier-mismatch negatives.
* ``formatVoiceRecordKey`` renders named keys in title case
(``Ctrl+Space``, ``Ctrl+Enter``).
* Existing fall-back-to-Ctrl+B contract preserved for empty input
AND unrecognised multi-char tokens.
Full TUI suite: 559/559 pass; ``tsc --noEmit`` clean.
Refs #18994 (round-1 review feedback)
Co-authored-by: asheriif <ahmedsherif95@gmail.com>
* test(tui): assert voice.toggle returns configured record_key
Salvage the backend regression from #19339 — asserts ``voice.toggle``
action=on AND action=status responses carry the configured
``voice.record_key`` end-to-end through ``_load_cfg()``. Keeps the
CLI→TUI parity contract visible in the Python test suite alongside
the existing frontend parser/matcher/formatter coverage from #19028.
* fix(tui): address Copilot review on #19835 voice.record_key wiring
Five tightenings on the parser + matcher + hydration surface, all
caught by the Copilot review on the PR — each one turns a silent
false-fire or display/binding skew into a deterministic behaviour.
* **isVoiceToggleKey ctrl branch was too permissive for named keys.**
The doc-default macOS Cmd+B muscle-memory fallback
(``isActionMod(key)`` on top of ``key.ctrl``) fired for every
configured key, so bare Esc — which hermes-ink reports with
``key.meta`` on some macOS terminals — triggered ``ctrl+escape``,
and Alt+Space / Alt+Tab triggered ``ctrl+space`` / ``ctrl+tab``.
Gate the fallback to the literal ``ctrl+b`` binding so any custom
chord requires the real Ctrl bit.
* **Alt branch guarded against Ctrl/Cmd co-press.** Without this,
Ctrl+Alt+<letter> and Cmd+Alt+<letter> also fired ``alt+<letter>``.
* **Dropped the ``meta`` modifier variant and its alias.** In
hermes-ink ``key.meta`` is Alt on xterm-style terminals and Cmd on
legacy macOS ones, so a literal ``meta+b`` config displayed as
``Cmd+B`` while matching Alt+B — exactly the kind of false
shortcut the PR was meant to remove. ``cmd`` / ``command`` now
collapse onto ``super`` (kitty-style ``key.super``, with a macOS
``key.meta`` fallback) and render as ``Cmd+B``. Unknown modifier
tokens fall back to the documented Ctrl+B default rather than
silently coercing to Ctrl.
* **Slash-command display/binding skew.** ``/voice status`` and
``/voice on`` rendered from the fresh gateway ``record_key``
response, but ``useInputHandlers()`` still bound the old key
until the next 5s mtime poll. Thread ``setVoiceRecordKey``
through ``SlashHandlerContext.voice`` and push the parsed spec
into frontend state on every response so text and binding stay
consistent.
* **Test coverage for the two paths Copilot flagged.** Added
vitest coverage for (a) the three-case ``/voice`` slash output
in ``createSlashHandler.test.ts`` and (b) the
``applyDisplay → voice.record_key`` hydration + omit-setter
back-compat paths in ``useConfigSync.test.ts``. Plus regression
cases for every false-fire scenario above.
Suite: 575/575 green, tsc --noEmit clean.
* fix(tui): address Copilot round-2 review on #19835
Three tightenings on the surface introduced in the round-1 fix:
* **``/voice tts`` reset custom bindings to Ctrl+B.** The ``tts`` branch
of ``voice.toggle`` omitted ``record_key`` from its response, so the
frontend's ``r.record_key ?? 'ctrl+b'`` coerced a user's custom
binding back to the default on every TTS toggle. Two-sided fix:
the backend now includes ``record_key`` on the ``tts`` branch (parity
with ``status``/``on``/``off``), and the slash handler only pushes
frontend state when the response actually carries ``record_key`` —
belt-and-suspenders against any future branch forgetting to include
it.
* **``super+b`` / ``win+b`` / ``cmd+b`` displayed "Cmd+B" on Linux and
Windows.** ``formatVoiceRecordKey`` rendered ``mod === 'super'`` as
``Cmd`` universally, which told non-mac users the wrong modifier to
press even though ``isVoiceToggleKey`` matched the right event bits.
Gate the label to ``isMac`` so non-mac renders ``Super+B``.
* **``control+b`` / ``ctrl + b`` lost the macOS Cmd+B fallback.**
``_isDefaultVoiceKey`` keyed off ``parsed.raw`` — so
semantically-equal aliases of the documented default dropped into
the strict branch even though they bind Ctrl+B. Compare on the
parsed spec (mod + ch + named) instead.
Coverage added: Linux ``Super+B`` rendering (and macOS ``Cmd+B``),
``control+b`` / ``ctrl + b`` accepting the Cmd+B fallback on darwin,
``/voice tts`` without ``record_key`` not clobbering cached binding,
and a backend regression asserting every ``voice.toggle`` branch
carries the configured key.
Suite: 579/579 TUI vitest green, 2/2 backend voice tests green,
tsc --noEmit clean.
* fix(tui): address Copilot round-3 review on #19835
Three classes of robustness issue caught on the second pass — all
revolve around malformed YAML tipping ``parseVoiceRecordKey`` or
``_voice_record_key`` into a crash instead of the documented
fallback.
* **Parser crashed on non-string YAML scalars.** ``config.get full``
returns raw ``yaml.safe_load`` output, so ``voice.record_key: 1``
or ``voice.record_key: true`` in a hand-edited config would hit
``.trim()`` on a number/bool and throw, breaking startup and
every mtime re-apply. Accept ``unknown`` at the signature, guard
with ``typeof raw !== 'string'``, and fall back to the default.
* **Backend blew up on non-dict ``voice:``.** Same YAML hazard on
the gateway side: ``voice: true`` / ``voice: cmd+b`` left
``_load_cfg().get("voice")`` as a bool/str, so ``.get("record_key")``
raised AttributeError and took every ``voice.toggle`` branch down
with it. Centralised the lookup in a single
``_voice_record_key()`` helper that ``isinstance``-guards both
``voice`` and ``record_key`` and falls back to ``ctrl+b``.
* **Multi-modifier chords silently dropped extras.** The previous
validator only checked the first modifier token, so ``ctrl+alt+r``
silently parsed as ``ctrl+r`` and ``cmd+ctrl+b`` as ``super+b`` —
a typo bound a different shortcut than the user configured.
Reject multi-modifier spellings outright; the classic CLI only
supports single-modifier bindings via prompt_toolkit's ``c-x`` /
``a-x`` rewrite, so this matches CLI parity.
Coverage added:
* ``parseVoiceRecordKey`` fallback on ``1`` / ``true`` / ``null`` /
``undefined`` / ``{}``.
* ``parseVoiceRecordKey`` fallback on ``ctrl+alt+r`` /
``cmd+ctrl+b`` / ``alt+ctrl+space``.
* ``test_voice_toggle_handles_non_dict_voice_cfg`` exercises
every non-dict ``voice:`` shape (bool, str, None, int, list) and
asserts each falls back to ``record_key: 'ctrl+b'``.
Suite: 581/581 TUI vitest green, 3/3 backend voice tests green,
tsc --noEmit clean.
* fix(tui): address Copilot round-4 review on #19835
Four final corners of the voice.record_key surface:
* **Bare-char configs silently coerced to ``ctrl+<key>``.** A config
like ``voice.record_key: o`` / ``space`` / ``escape`` fell through
to the default ``mod = 'ctrl'`` and silently bound Ctrl+O, while
the classic CLI's prompt_toolkit would bind the raw key (no
rewrite) — so the two runtimes silently disagreed on what "o"
means. Require an explicit modifier; bare-char configs fall back
to the documented Ctrl+B default.
* **Reserved ctrl+<letter> bindings would never fire.**
``useInputHandlers()`` intercepts ``ctrl+c`` (interrupt),
``ctrl+d`` (quit), and ``ctrl+l`` (clear screen) before the voice
check runs, so those configs would be advertised in /voice
status but the advertised shortcut never actually triggers
push-to-talk. Added ``_RESERVED_CTRL_CHARS`` at parse time so
the user gets the documented default instead of a dead shortcut.
(``alt+c``, ``cmd+l``, etc. are not intercepted and stay usable.)
* **``_load_cfg()`` root itself may be a non-dict.**
``_voice_record_key()`` isinstance-guarded the ``voice`` subkey
but not the root — a malformed config.yaml that collapsed to a
scalar/list at the top level (``config.yaml: true`` or ``[]``)
would still raise on ``.get("voice")``. Added the top-level
guard too so every malformed shape falls back to ``ctrl+b``.
* **Stale header comment on ``isVoiceToggleKey``.** The doc-comment
still claimed "On macOS we additionally accept the platform
action modifier (Cmd) for the configured letter" even though the
implementation gates the Cmd fallback to the documented default
only. Rewrote to match.
Coverage added:
* ``parseVoiceRecordKey`` fallback on bare chars (``o``, ``b``,
``space``, ``escape``).
* ``parseVoiceRecordKey`` fallback on ``ctrl+c`` / ``ctrl+d`` /
``ctrl+l``; positive case for ``alt+c`` / ``cmd+l`` still usable.
* Backend ``test_voice_toggle_handles_non_dict_voice_cfg`` now
exercises 5 non-dict shapes at the YAML root too.
Suite: 583/583 TUI vitest green, 3/3 backend voice tests green,
tsc --noEmit clean.
* fix(tui): address Copilot round-5 review on #19835
Three follow-ups on the voice matcher's modifier + shift discipline:
* **``super`` branch falsely fired on Alt+<key> / bare Esc on macOS.**
``isVoiceToggleKey`` accepted ``isMac && key.meta`` as a Cmd
fallback for the ``super`` modifier — but hermes-ink sets
``key.meta`` for plain Alt/Option AND for bare Escape on some
macOS terminals. A ``cmd+b`` config silently fired on Alt+B;
``cmd+space`` on Alt+Space; ``cmd+escape`` on bare Esc. Drop the
fallback and require the literal ``key.super`` bit. Legacy-
terminal users who need Cmd should upgrade to a kitty-protocol
terminal or bind ``alt+X`` explicitly.
* **Shift bit was never checked.** The parser rejects multi-
modifier configs like ``ctrl+shift+tab``, but the runtime
matcher didn't check ``key.shift`` — so ``ctrl+tab`` also fired
on Ctrl+Shift+Tab and ``alt+enter`` on Alt+Shift+Enter.
Early-return on ``key.shift === true`` so the runtime only fires
the exact chord the user configured.
* **Test leaked ``HERMES_VOICE=1`` into later tests.**
``voice.toggle`` action=on writes to ``os.environ`` directly
(CLI parity, runtime-only flag); ``test_voice_toggle_returns_
configured_record_key`` dispatched action=on without letting
monkeypatch take ownership of the var first. Any later test
that read voice mode in the same Python process could inherit a
stale enabled state. Added ``monkeypatch.setenv("HERMES_VOICE",
"0")`` up front so monkeypatch restores the original value at
teardown.
Coverage added:
* ``cmd+b`` / ``cmd+space`` / ``cmd+escape`` do NOT fire on
``key.meta``-only events on darwin.
* ``ctrl+tab`` / ``alt+enter`` / ``ctrl+o`` reject matches when
``key.shift`` is held; sanity cases without Shift still fire.
Suite: 585/585 TUI vitest green, 3/3 backend voice tests green,
tsc --noEmit clean.
* fix(tui): address Copilot round-6 review on #19835
Three classes of modifier-discipline tightening + one config-surface
honesty fix:
* **Default ``ctrl+b`` Cmd fallback leaked Alt+B.** The default's
macOS Cmd+B muscle-memory path used ``isActionMod(key)``, which
returns ``key.meta || key.super`` on darwin. hermes-ink also
reports plain Alt as ``key.meta``, so Alt+B silently fired the
default binding. Replaced with strict ``isMac && key.super ===
true`` — kitty-style Cmd+B still works, Alt+B correctly
rejected. Legacy-terminal mac users (Terminal.app without
CSI-u) now get raw Ctrl+B only; the documented default still
works everywhere.
* **ctrl / super branches accepted extra modifier bits.** The
parser rejects multi-modifier configs like ``ctrl+alt+o``, but
the runtime matcher was permissive — ``ctrl+o`` fired on
Ctrl+Alt+O / Ctrl+Cmd+O, and ``super+b`` fired on Cmd+Alt+B /
Ctrl+Cmd+B. Added strict ``!key.alt && !key.meta && key.super
!== true`` on ctrl, and ``!key.ctrl && !key.alt && !key.meta``
on super, so the runtime only fires the exact chord the parser
would let you configure.
* **Dropped ``cmd`` / ``command`` aliases.** They parsed to
``super`` and rendered as ``Cmd+X``, but legacy macOS terminals
report Cmd as ``key.meta`` (same signal as Alt), so a
``cmd+o`` config was advertised as working but never actually
fired on Terminal.app-without-CSI-u. That recreated the
"displayed shortcut does not work" problem this PR was meant to
remove. Users who want the platform action modifier spell it
``super`` / ``win`` — that matches the unambiguous ``key.super``
bit, and kitty-style macOS terminals render it as ``Cmd+X`` via
platform-aware formatter.
Coverage updated:
* Default ctrl+b no longer fires on Alt+B via ``key.meta`` leak;
raw Ctrl+B and kitty-style Cmd+B still fire.
* ``ctrl+o`` rejects Ctrl+Alt+O / Ctrl+Cmd+O / Ctrl+Meta+O chords.
* ``super+b`` rejects Cmd+Alt+B / Cmd+Meta+B / Ctrl+Cmd+B chords.
* ``cmd+b`` / ``command+b`` / ``meta+b`` all fall back to the
documented default at parse time (joined the ambiguous-mac-mod
rejection class).
* Round-2 expectations that asserted ``cmd+b`` parsed as super
and accepted ``key.meta`` on darwin updated to reflect the new
stricter contract.
Suite: 588/588 TUI vitest green, 3/3 backend voice tests green,
tsc --noEmit clean.
* fix(tui): address Copilot follow-up on wire typing + escape precedence
Two follow-ups from the latest Copilot pass:
* **Config wire typing honesty (`gatewayTypes.ts`)**
`config.get full` forwards raw `yaml.safe_load()` output, so
`voice.record_key` can be any scalar/container when hand-edited.
Typing it as `string` suggests a normalized contract that the
backend does not guarantee and makes unsafe callers more likely.
Change `ConfigVoiceConfig.record_key` to `unknown` with an
explicit comment that callers must normalize at runtime.
* **Escape-based voice bindings were swallowed before voice check**
`useInputHandlers()` handled `key.escape` for queue-edit cancel and
selection clear before `isVoiceToggleKey(...)`, so configured
`ctrl+escape` / `alt+escape` / `super+escape` chords were advertised
but never toggled recording in those UI states.
Add an early escape+voice check before generic Esc handlers so
escape-based voice bindings win when configured, while plain Esc
behavior remains unchanged.
Also updated PR #19835 description text to remove stale cmd/command
alias claims and match the current parser contract.
* fix(tui): pass configured voice shortcut through TextInput layer
Thread the live parsed voiceRecordKey into TextInput so configured voice.record_key chords bubble to useInputHandlers instead of being consumed as editor input. This removes the last hardcoded Ctrl+B pass-through in the composer path while preserving existing global control chord behavior.
* fix(tui): require explicit alt bit for escape-based alt chords
Hermes-ink reports bare Escape as meta=true+escape=true on some terminals, so a configured alt+escape binding was firing on bare Esc. Require an explicit key.alt bit when the configured named key is escape so plain Esc stays plain Esc; kitty-style alt+escape still fires.
* fix(tui): harden voice.record + TextInput paste + super-mod reserved list
Three round-7 Copilot follow-ups on #19835:
- voice.record start handler used _load_cfg().get('voice', {}).get(...) without
shape checks, so malformed YAML (bool/scalar/list) returned 5025 instead of
using VAD defaults. Centralized _voice_cfg_dict() helper and type-guarded
silence_threshold/silence_duration with numeric fallbacks.
- TextInput pass-through check moved above paste/copy handling so configured
voice chords (ctrl+v / alt+v / cmd+v) beat the composer's paste/copy
defaults.
- parser now also rejects super+{c,d,l,v} — on macOS those are
copy/exit/clear/paste and would be advertised in /voice status but never
actually toggle recording.
* Potential fix for pull request finding

* fix(tui): round-8 Copilot review — allow ctrl+x, gate super reservations to macOS, preserve voice key on transient RPC failure
Three round-8 Copilot follow-ups on #19835:
- Revert ctrl+x addition to _RESERVED_CTRL_CHARS (landed via Copilot Autofix
commit 731ec86): ctrl+x is only claimed during queue-edit
(queueEditIdx !== null), so voice works the rest of the session and
matches CLI ctrl+<letter> parity.
- Gate super+{c,d,l,v} reservation to isMac. Linux/Windows TUI globals key
off Ctrl, so kitty/CSI-u super+<letter> configs don't collide on non-mac
and should stay usable.
- applyDisplay() now skips setVoiceRecordKey when cfg is null so one
transient quietRpc() failure after a config edit doesn't clobber the
cached binding back to Ctrl+B until the next successful poll.
New coverage:
- parseVoiceRecordKey preserves ctrl+x on linux
- super+{c,d,l,v} rejected on darwin, allowed on linux
- applyDisplay(null, ...) leaves voiceRecordKey untouched
* fix(cli,tui): normalize voice.record_key aliases across CLI + TUI for parity
Round-9 Copilot review on #19835: TUI accepted control+/option+/opt+/super+/win+ aliases but the classic CLI only rewrote literal ctrl+/alt+ before handing to prompt_toolkit, so a TUI-valid config silently bound a different (or no) shortcut in the CLI.
- Added normalize_voice_record_key_for_prompt_toolkit() in hermes_cli/voice.py with a single alias table (ctrl/control/alt/option/opt → c-/a-).
- Wired it into all three cli.py sites (_enable_voice_mode hint, _show_voice_status display, and the prompt_toolkit binding in _register_voice_handler).
- /voice status display now renders control+x as Ctrl+X and option+x as Alt+X (canonical casing) to match TUI formatVoiceRecordKey.
- super/win/windows are intentionally left unchanged: prompt_toolkit has no super modifier, so the CLI will reject them loudly at startup rather than silently binding Ctrl+B. Documented this split at both the TUI _MOD_ALIASES comment and the CLI normalizer docstring.
- Added tests covering ctrl/control/alt/option/opt mapping, case-insensitivity, non-string fallback, empty-string fallback, and super/win pass-through.
* fix(cli): port TUI parser contract into CLI voice.record_key normalizer
Round-10 Copilot review on #19835.
hermes_cli/voice.py's normalize_voice_record_key_for_prompt_toolkit() previously did blind substring replacement with no trim/validate step, so the CLI diverged from the TUI parser on:
- whitespace ('ctrl + b' -> 'c- b' instead of 'c-b')
- typoed named keys ('ctrl+spcae' passed through as 'c-spcae' and prompt_toolkit would reject at startup)
- bare-char configs ('o' should fall back, not pass through as 'o')
- multi-modifier chords ('ctrl+alt+r')
- reserved ctrl chars ('ctrl+c/d/l')
- unknown modifiers ('meta+b' / 'shift+b')
- named-key aliases ('return'/'esc'/'bs'/'del' not collapsed to prompt_toolkit canonicals)
Port the TUI parser contract into Python (_VOICE_MOD_ALIASES, _VOICE_NAMED_KEYS, _VOICE_RESERVED_CTRL_CHARS) so one config value binds the same shortcut in both runtimes.
Also added format_voice_record_key_for_status() shared between the PTT hint and /voice status display. Non-string scalars (voice.record_key: true / 1) now surface as 'Ctrl+B' instead of the raw scalar — /voice status no longer advertises a shortcut that can never bind.
Tests: 29/29 in test_voice_wrapper.py, including 11 new regressions covering whitespace, named-key aliases, typos, bare-char, multi-modifier, reserved ctrl, unknown mods, non-string fallback, and formatter contract.
* fix(cli): shape-safe voice config read + graceful super/win fallback
Round-11 Copilot review on #19835.
Two remaining cross-runtime gaps:
1. load_config().get('voice', {}) still assumed voice was a dict, so a hand-edited voice: true / voice: cmd+b at the top level raised AttributeError before the voice UI could start. Added voice_record_key_from_config(cfg) to hermes_cli/voice.py that isinstance-guards both the root and the voice subkey. All three cli.py read sites (_enable_voice_mode hint, _show_voice_status, PTT binding) now use it.
2. The CLI normalizer previously passed super+/win+/windows+ through unrewritten so prompt_toolkit would reject them loudly at startup — but that crash was a worse UX than a silent fallback. Normalizer now returns c-b for those spellings, and the PTT binding site logs a warning so users see why their TUI-only shortcut isn't binding in the CLI.
Coverage: 34/34 in tests/hermes_cli/test_voice_wrapper.py (5 new cases for voice_record_key_from_config + malformed-root + malformed-voice + extractor/normalizer composition).
* fix(cli): self-audit cleanup — remaining voice-config shape safety + doc drift
Self-review of the voice.record_key change set turned up four remaining items Copilot would very likely flag next round:
1. cli.py _voice_start_continuous still read load_config().get('voice', {}).get('silence_threshold') without an isinstance guard, so a hand-edited voice: true / voice: cmd+b (non-dict) raised AttributeError on VAD recording start. Shape-safe coerce the voice dict and numeric-guard silence_threshold/silence_duration.
2. cli.py _enable_voice_mode's auto_tts check had the same bug — fixed with the same isinstance guard.
3. hermes_cli/voice.py module comment on _VOICE_MOD_ALIASES still said super/win/windows 'pass through unchanged and prompt_toolkit's add() call loudly rejects them at startup'. Round 11 changed the normalizer to silently fall back to c-b with a warning at the binding site; updated the comment to match.
4. ui-tui/src/lib/platform.ts header comment had the same stale 'CLI will loudly reject them at startup' claim; updated to 'falls back to the documented default and logs a warning'.
No behavior change on the code paths already covered by test_voice_wrapper.py; the two cli.py fixes are defensive against malformed YAML that previous rounds already hardened in tui_gateway/server.py but missed in the classic CLI.
* fix(cli,tui): round-12 Copilot review — alt-collide on mac, bool-in-int guards, voice UI hardcodes, mtime-reload test
Five round-12 Copilot review items on #19835:
1. platform.ts: hermes-ink reports Alt as key.meta on many terminals; isActionMod on darwin accepts key.meta as the action modifier. So alt+c/d/l get claimed by isCopyShortcut / isAction('d')/'l') before the voice check. Reject those configs at parse time on macOS only (non-mac keeps them usable).
2. cli.py: four remaining hardcoded 'Ctrl+B' sites in voice-facing UI (_get_voice_status_fragments status bar, _voice_start_recording hints, _get_placeholder composer text) were still lying about non-default configs. Added self._voice_record_key_label() shared helper and wired it into all three sites.
3. server.py + cli.py: bool is a subclass of int, so isinstance(silence_threshold, (int, float)) accepted True/False from malformed YAML and forwarded 1/0 to the VAD engine. Exclude bool explicitly so boolean typos fall back to the documented 200 / 3.0 defaults.
4. useConfigSync.ts: extracted the config.get-full fetch+apply body into a shared hydrateFullConfig() helper. Both the initial hydration and mtime-reload paths now use it, so the polling/RPC wiring is exercised by direct unit tests (4 new cases: fresh apply, reapply on new value, transient RPC failure preserves cache, back-compat without voice setter).
5. Added alt+{c,d,l} rejection regressions on darwin + allow on linux, and bool-leak regressions for both silence_threshold and silence_duration in tests/test_tui_gateway_server.py.
Suite: 602/602 TUI vitest, 38/38 backend voice tests, typecheck + lints clean.
* fix(cli): cache voice record-key label at binding time + status-bar coverage
Round-13 Copilot review on #19835.
_voice_record_key_label() was reading live config on every render, which caused two problems:
1. prompt_toolkit registers the push-to-talk binding once at session start (@kb.add(_voice_key)); the binding does NOT re-read config. Editing voice.record_key mid-session would switch the status-bar / placeholder / recording-hint label to the new shortcut while the actual keybinding stayed on the startup chord — reintroducing the display/binding drift this whole PR is fighting.
2. Hot render path: during recording the UI is invalidated every 150ms, so re-loading + deep-merging config on every call added avoidable UI overhead.
Fix: cache the label at the same site that registers the prompt_toolkit binding via new set_voice_record_key_cache(raw_key). _voice_record_key_label() now just returns the cached value (falls back to 'Ctrl+B' before startup). Status/placeholder/hint are always in sync with the live binding; no config reload per render.
Also added 4 regression cases to tests/cli/test_cli_status_bar.py: configured ctrl+<letter> renders in both wide and compact status bars, configured named key (ctrl+space) renders in the recording hint, pre-startup absent cache falls back to Ctrl+B, and malformed configs (bool True) fall through the formatter to Ctrl+B.
Suite: 60/60 test_cli_status_bar + test_voice_wrapper, typecheck + lints clean.
* fix(cli): route /voice on + /voice status through startup-pinned label; mac alt+cdl parity
Round-14 Copilot review on #19835. All three comments legit:
1. _enable_voice_mode still formatted label from live load_config() — mid-session config edit would make /voice on announce the new shortcut while the prompt_toolkit binding stayed the startup chord. Use self._voice_record_key_label() (cached at binding time, round-13) so /voice on cannot drift from the live binding.
2. _show_voice_status had the same bug — /voice status reported live config instead of the pinned startup binding. Fixed the same way.
3. CLI normalizer accepted alt+c/alt+d/alt+l even though the TUI parser rejects them on macOS (Copilot round-12 — hermes-ink reports Alt as key.meta, isActionMod on darwin accepts it, collides with isCopyShortcut / isAction). Added _VOICE_RESERVED_ALT_CHARS_MAC = {c,d,l} gated to sys.platform == 'darwin' so a shared config like option+c falls back to c-b on both runtimes on macOS; non-mac still binds a-c.
Coverage: 4 new tests in test_voice_wrapper.py covering mac alt+cdl rejection, linux alt+cdl allowed, option/opt alias forms, and mac-specific exclusions for other alt letters. 62/62 in voice wrapper + status bar suites.

#19884 added a prompt_toolkit key binding for Ctrl+Shift+C to
"prevent Hermes from intercepting the keystroke as an interrupt
signal." #19895 then wrapped the binding in try/except after
discovering it crashed startup with ValueError on every platform.
Both PRs were based on a misreading of how terminal key events
propagate:
1. Terminal emulators (GNOME Terminal, iTerm2, kitty, Windows Terminal,
etc.) intercept Ctrl+Shift+C before the keystroke reaches the
application's stdin. prompt_toolkit never sees it. The binding
could never have intercepted anything.
2. prompt_toolkit's key spec parser doesn't recognise 'c-S-c' on any
platform — the Shift modifier is meaningless on control-sequence
keys. Verified: every prompt_toolkit version raises 'Invalid key:
c-S-c' at registration time.
The handler is dead code. Delete it and leave a comment explaining
why no binding is needed here. Ctrl+Q alias (#19884's other addition)
stays — that's a real prompt_toolkit key and a legitimate interrupt
shortcut.
Verified the CLI starts cleanly — key binding phase no longer raises
and the subsequent chat flow reaches the provider setup check without
error.
PR #19884 added @kb.add('c-S-c') unconditionally. prompt_toolkit raises
ValueError("Invalid key: c-S-c") during HermesCLI.__init__ on platforms
where this key spec is not recognised — the process exits before reaching
the prompt loop. Reported on macOS (#19894) and Linux (#19896) immediately
after #19884 landed.
Fix: wrap the registration in try/except ValueError so that startup
continues cleanly on any platform/version that rejects the spec. Where
the spec is accepted the binding is registered normally as a no-op,
allowing the terminal to handle Ctrl+Shift+C natively as before.
Fixes#19894Fixes#19896
The contributor's PR silently swallowed ValueError from
SessionDB.set_session_title() with bare except Exception: pass.
Users typing /new <title> with an already-in-use title got an
untitled session and no feedback.
Changes:
- cli.py: catch ValueError from both sanitize_title() and
set_session_title(); print the error and mark the session
untitled in the banner (never echo the rejected title back).
- gateway/run.py: append a warning note to the reset reply on
title rejection; reflect the accepted title in the header.
- Add regression tests for the duplicate-title path in CLI and
gateway.
Also map exx@example.com -> @exxmen in scripts/release.py.
Allow users to start a fresh session and immediately set its title by
passing a name to /new (or /reset):
/new Refactor auth module
Changes:
- hermes_cli/commands.py: add args_hint='[name]' to /new command
- cli.py: parse title argument in process_command(), pass to new_session()
- cli.py: new_session() accepts title=None, sets title via SessionDB
- gateway/run.py: _handle_reset_command() parses title, sets on new entry
- gateway/session.py: reset_session() accepts optional display_name
- tests: add test_new_session_with_title, test_reset_command_with_title,
test_new_command_in_help_output
All 36 affected tests pass.
The 'q' alias is defined for 'queue' command in commands.py:93.
The hardcoded 'q' in cli.py:5910 was dead code - resolve_command('q')
returns the queue CommandDef, so canonical would never be 'q'.
Removes the misleading check without changing any behavior:
- /quit and /exit still exit (defined aliases)
- /q still maps to queue (as intended)
The old CWD heuristic was fooled by:
1. TERMINAL_CWD persisted to .env by `hermes config set terminal.cwd`
2. Inherited TERMINAL_CWD from parent hermes processes
3. Only resolved when config had a placeholder value (not explicit paths)
Fix:
- load_cli_config() unconditionally uses os.getcwd() for local backend
- TERMINAL_CWD always force-exported in CLI mode (overrides stale values)
- Gateway sets _HERMES_GATEWAY=1 marker so lazy cli.py imports don't clobber
- Remove terminal.cwd from config-set .env sync map (prevents re-poisoning)
- Clarify setup wizard label as 'Gateway working directory'
Closes#19214
CLI/TUI sessions on the local backend now unconditionally use
os.getcwd() as the working directory. The terminal.cwd config value is
only consumed by gateway/cron/delegation modes (where there's no shell
to cd from).
Previously, 'hermes setup' would write an absolute path (e.g. $HOME)
into terminal.cwd which then pinned the CLI to that directory regardless
of where the user launched hermes from. This was a silent foot-gun —
the user's 'cd' was being ignored.
Changes:
1. cli.py: Restructured CWD resolution — if TERMINAL_CWD is not already
set by the gateway, and the backend is local, always use os.getcwd().
Config terminal.cwd is irrelevant for interactive CLI/TUI sessions.
2. setup.py: Moved the cwd prompt from setup_terminal_backend() to
setup_gateway(). It now only appears when configuring messaging
platforms and is labeled 'Gateway working directory'.
3. Tests: Rewrote test_cwd_env_respect.py to validate the new behavior:
explicit config paths are ignored for CLI, gateway pre-set values are
preserved, non-local backends keep their config paths.
4. Docs: Updated configuration.md, profiles.md, and
environment-variables.md to clarify that terminal.cwd only affects
gateway/cron mode on local backend.
Closes#19214
Two narrow fixes for long pasted messages silently disappearing:
1. _expand_paste_references: replace path.exists() + read_text() with
try/except (OSError, IOError). Closes the TOCTOU window where a paste
file deleted between check and read raised FileNotFoundError, bubbled
up through process_loop's outer except, and silently dropped the
user's input. Failures now return the placeholder text and log a
warning.
2. process_loop outer except: logger.warning() instead of print().
prompt_toolkit's TUI swallows stdout, so 'Error: …' was invisible
to the user. Logged errors are discoverable via hermes logs.
Dropped the larger interrupt_queue→pending_input drain that was part of
the original PR — that's a separate class of input-drop (in-progress
interrupt handling) unrelated to the paste-file TOCTOU reported in the
issue, and worth its own review.
Salvage of #17939.
Prevents ghost sessions from accumulating in state.db when the TUI/web
dashboard is opened and closed without sending a message.
Changes:
- run_agent.py: Add _ensure_db_session() gate method, called at
run_conversation() entry. Remove eager create_session() from __init__.
Handle compression rotation flag correctly.
- tui_gateway/server.py: Remove eager db.create_session() in
_start_agent_build(). Add post-first-message pending_title re-apply.
- hermes_state.py: Extract _insert_session_row() shared helper (DRY).
Add prune_empty_ghost_sessions() for one-time migration.
- cli.py: One-time ghost session prune on startup. Fix _pending_title
to call _ensure_db_session() before set_session_title().
- hermes_cli/main.py: Guard TUI exit summary on message_count > 0.
- tests: Update test_860_dedup to call _ensure_db_session() before
direct _flush_messages_to_session_db() calls.
Closes: ghost session clutter in hermes sessions list and web dashboard.
Add a standing-goal slash command that keeps Hermes working toward a
user-stated objective across turns until it is achieved, paused, or
the turn budget runs out. Our take on the Ralph loop — cf. Codex CLI
0.128.0's /goal.
After each turn, a lightweight auxiliary-model judge call asks 'is
this goal satisfied by the assistant's last response?'. If not, and
we're under the turn budget (default 20), Hermes feeds a continuation
prompt back into the same session as a normal user message. Any real
user message preempts the continuation loop automatically.
Judge failures fail OPEN (continue) so a flaky judge never wedges
progress — the turn budget is the real backstop.
### Commands
- `/goal <text>` — set a standing goal (kicks off the first turn)
- `/goal` or `/goal status` — show current state
- `/goal pause` — pause the continuation loop
- `/goal resume` — resume (resets turn counter)
- `/goal clear` — drop the goal
Works on both CLI and gateway platforms via the central CommandDef
registry.
### Design invariants preserved
- **Prompt cache**: continuation prompts are regular user-role
messages appended to history. No system-prompt mutation, no toolset
swap.
- **Role alternation**: continuation is a user turn, never injected
mid-tool-loop.
- **Session persistence**: goal state lives in SessionDB.state_meta
keyed by `goal:<session_id>`, so `/resume` picks it up.
- **Mid-run safety**: on the gateway, `/goal status|pause|clear` are
allowed mid-run (control-plane only); setting a new goal requires
`/stop` first so we don't race a second continuation prompt against
the current turn.

The user-visible /compress banner and the post-compression last_prompt_tokens
writeback both counted only the raw message transcript (chars/4). With a 15KB
system prompt and 30 tool schemas (~26KB), a 4-message transcript that looks
like ~45 tokens to the transcript-only estimator is really ~10.5K tokens of
request pressure — a 234x gap.
Two user-facing consequences:
- Banner shows 'Compressing … (~45 tokens)…' while compression is actually
firing on 10K+ tokens of real pressure, confusing users about why
compression triggered (reported by @codecovenant on X; #6217).
- Post-compression last_prompt_tokens writeback omits tool schemas, so the
next should_compress() check compares real usage against a stale
underestimate — compression triggers late, potentially past the model's
context limit on small-context models (#14695).
Swap estimate_messages_tokens_rough() for estimate_request_tokens_rough()
at every user-visible banner and at the post-compression writeback.
estimate_request_tokens_rough() already existed for exactly this purpose
and includes system prompt + tool schemas.
Touched call sites:
- run_agent.py: post-compression last_prompt_tokens writeback, post-tool
call should_compress() fallback when provider usage is missing
- cli.py: /compress banner + summary
- gateway/run.py: gateway /compress banner + summary
- tui_gateway/server.py: TUI /compress status + summary
- acp_adapter/server.py: ACP /compact before/after
Left intentionally alone:
- Session-hygiene fallback and the 'no agent' /status path in gateway/run.py
— no agent instance is in scope to query for system prompt/tools, and the
existing 30-50% overestimate wobble on hygiene is safety-accepted.
- Verbose-mode 'Request size' logging — informational only, already counts
system prompt via api_messages[0].
Also relabels the feedback line from 'Rough transcript estimate' to
'Approx request size' so the metric label matches what it actually measures.

Closes#14695Closes#6217
Widens the cherry-picked fix from @jatingodnani (#17343) to the
gateway path. On main, user_config.agent.disabled_toolsets was only
honored by _get_platform_tools' name-level subtraction — it did not
catch tools pulled in implicitly by a composite toolset (browser
includes web_search, hermes-* platforms include most tools).
Changes:
- gateway/run.py: resolve disabled_toolsets alongside enabled_toolsets
and pass to AIAgent at both user-facing construction sites (normal
message loop + single-turn cron-like path). Hygiene/compression
agents (fixed enabled_toolsets=[memory]) are intentionally untouched.
- gateway/run.py: add (agent, disabled_toolsets) to
_CACHE_BUSTING_CONFIG_KEYS so editing the list in config.yaml
invalidates the cached AIAgent on the next message.
- cli.py: drop unused 'import platform' left over from PR #17343's
import churn; restore 'import sys' used throughout the file.
- model_tools.py: drop unused 'import os, sys' added by PR #17343;
fix comment reference from #15291 (unrelated OAuth issue) to #17309.

Refactor tool resolution logic in model_tools.py to ensure that
disabled_toolsets are always subtracted at the end, preventing
composite toolsets (e.g. 'browser') from implicitly enabling tools
that should be hidden.
- Added 'disabled_toolsets' to DEFAULT_CONFIG in hermes_cli/config.py
- Updated HermesCLI in cli.py to load and propagate disabled toolsets to AIAgent
- Implemented robust two-phase resolution (additive then subtractive) in model_tools.py
When the self-improvement background review fires after a turn, it runs
in a bg thread and emits a ' 💾 <summary>' line to announce what it
saved to memory or skills. Two problems made this invisible to users
even when the review successfully modified a skill:
1. The print went through `_cprint` (prompt_toolkit's print_formatted_text)
on a bg thread while the CLI's PromptSession was live. Direct
print_formatted_text races with the input-area redraw and the line
can land behind/above the prompt, scrolled off without the user
seeing it.
2. The message said only '💾 Skill created.' / '💾 Memory updated'
with no indication that the self-improvement loop was the one doing
this. Users who did catch the line couldn't tell the background
review from some other agent action.
Fixes:
- `_cprint` now detects when it's called from a non-app thread with a
running prompt_toolkit Application, and routes through
`run_in_terminal` via `loop.call_soon_threadsafe`. That pauses the
input, prints the line above the prompt, and redraws — the normal
prompt_toolkit contract for bg-thread output. Direct-print fallback
preserved for the no-app / same-thread / import-error paths. Affects
every bg-thread emission, not just the review summary (curator
summaries and auxiliary failure prints benefit too).
- The summary now reads ' 💾 Self-improvement review: <summary>' in
both the CLI and the gateway `background_review_callback` path, so
the origin is unambiguous.
Tests:
- New `tests/cli/test_cprint_bg_thread.py` covers all five routing
branches (no app, app-not-running, cross-thread schedule, same-thread
direct, app-loop-attribute-error, import-error).
- New case in `tests/run_agent/test_background_review.py` asserts the
attributed prefix shows up in both `_safe_print` and
`background_review_callback`.
Live E2E: exercised _cprint from a bg thread inside a real Application
event loop; confirmed get_app_or_none() sees the app, call_soon_threadsafe
schedules run_in_terminal, and the inner _pt_print runs.
When a user sets model.context_length in config.yaml, the value was only
used for Hermes' internal compression decisions (context_compressor) but
NOT for Ollama's num_ctx parameter. Ollama auto-detects context from GGUF
metadata (often 256K+) and allocates that much VRAM regardless of the
user's config — causing OOM on smaller GPUs like the P100 (16GB).
Root cause: two separate context values existed independently:
- context_compressor.context_length = config value (e.g. 65536) ✓
- _ollama_num_ctx = GGUF metadata value (e.g. 256000) ✗ ignored config
Changes:
1. Cap Ollama num_ctx to config context_length (run_agent.py)
When model.context_length is explicitly set and no explicit
ollama_num_ctx override exists, cap the auto-detected GGUF value
to the user's context_length. This is the core fix — it prevents
Ollama from allocating more VRAM than the user budgeted.
2. Pass config_context_length through all secondary call sites
Several paths called get_model_context_length() without the config
override, falling through to the 256K default fallback:
- cli.py: @-reference expansion and /model switch display
- gateway/run.py: @-reference expansion and /model switch display
- tui_gateway/server.py: @-reference expansion
- hermes_cli/model_switch.py: resolve_display_context_length()
3. Normalize root-level context_length in config (hermes_cli/config.py)
_normalize_root_model_keys() now migrates root-level context_length
into the model section, matching existing behavior for provider and
base_url. Users who wrote `context_length: 65536` at the YAML root
instead of under `model:` had it silently ignored.
4. Fix misleading comments (agent/model_metadata.py)
DEFAULT_FALLBACK_CONTEXT is 256K (CONTEXT_PROBE_TIERS[0]), not 128K
as two comments stated.
Tests: 3 new tests for root-level context_length normalization.
All existing context_length tests pass (96 tests).
Reloading MCP servers rebuilds the tool set for the active session, which
invalidates the provider prompt cache (tool schemas are baked into the
system prompt). The next message re-sends full input tokens — can be
expensive on long-context or high-reasoning models.
To surface that cost, /reload-mcp now routes through a new slash-confirm
primitive with three options: Approve Once / Always Approve / Cancel.
'Always Approve' persists approvals.mcp_reload_confirm: false so future
reloads run silently.
Coverage:
* Classic CLI (cli.py) — interactive numbered prompt.
* TUI (tui_gateway + Ink ops.ts) — text warning on first call; `now` /
`always` args skip the gate; `always` also persists the opt-out.
* Messenger gateway — button UI on Telegram (inline keyboard), Discord
(discord.ui.View), Slack (Block Kit actions); text fallback on every
other platform via /approve /always /cancel replies intercepted in
gateway/run.py _handle_message.
* Config key: approvals.mcp_reload_confirm (default true).
* Auto-reload paths (CLI file watcher, TUI config-sync mtime poll) pass
confirm=true so they do NOT prompt.
Implementation:
* tools/slash_confirm.py — module-level pending-state store used by all
adapters and by the CLI prompt. Thread-safe register/resolve/clear.
* gateway/platforms/base.py — send_slash_confirm hook (default 'Not
supported' → text fallback).
* gateway/run.py — _request_slash_confirm helper + text intercept in
_handle_message (yields to in-progress tool-exec approvals so
dangerous-command /approve still unblocks the tool thread first).
Tests:
* tests/tools/test_slash_confirm.py — primitive lifecycle + async
resolution + double-click atomicity (16 tests).
* tests/hermes_cli/test_mcp_reload_confirm_gate.py — default-config
shape + deep-merge preserves user opt-out (5 tests).
Targeted runs (hermetic): 89 passed (slash-confirm, config gate,
existing agent cache, existing telegram approval buttons).
Salvage-follow-up to @shannonsands's /reload-skills PR. Trims the feature to
match the design: user-initiated rescan, no prompt-cache reset, no new
schema surface, no phantom user turn, and the next-turn note carries each
added/removed skill's 60-char description (not just its name).
Changes vs the original PR:
* Drop the in-process skills prompt-cache clear in reload_skills(). Skills
are invoked at runtime via /skill-name, skills_list, or skill_view —
they don't need to live in the system prompt for the model to use them.
Keeping the cache intact preserves prefix caching across the reload so
/reload-skills pays no cache-reset cost. (MCP has to break the cache
because tool schemas must be known at conversation start; skills do not.)
* Drop the skills_reload agent tool and SKILLS_RELOAD_SCHEMA from
tools/skills_tool.py, plus the four skills_reload enumerations in
toolsets.py. No new schema surface — agents can already see a freshly-
installed skill via skill_view / skills_list the moment it's on disk.
* Replace the phantom 'role: user' turn injection with a one-shot queued
note. CLI uses self._pending_skills_reload_note (same pattern as
_pending_model_switch_note, prepended to the next API call and cleared).
Gateway uses self._pending_skills_reload_notes[session_key]. The note
is prepended to the NEXT real user message in this session, so message
alternation stays intact and nothing out-of-band is persisted to the
transcript.
* reload_skills() now returns added/removed as
[{'name': str, 'description': str}, ...] (description truncated to 60
chars — matches the curator / gateway adapter budget). The injected
next-turn note formats each entry as 'name — description' so the model
can actually reason about which new skills to call without running
skills_list first.
* Only emit the note when the diff is non-empty. On empty diff, print
'No new skills detected' and do nothing else.
* Tests rewritten to cover the queue semantics, the description payload,
and a regression guard that the prompt-cache snapshot is preserved.
Adds a public reload path for the in-process skill caches so newly
installed (or removed) skills become visible mid-session without a
gateway restart. Mirrors the shape of /reload-mcp.
Three surfaces:
* /reload-skills slash command — CLI (cli.py) and gateway (gateway/run.py),
with /reload_skills alias for Telegram autocomplete and an explicit
Discord registration.
* skills_reload agent tool (tools/skills_tool.py) — lets agents/subagents
pick up freshly-installed skills via tool call.
* agent.skill_commands.reload_skills() — shared helper that clears
_skill_commands, _SKILLS_PROMPT_CACHE (in-process LRU), and the
on-disk .skills_prompt_snapshot.json, then returns an added/removed
diff plus the new total count.
Tested:
* tests/agent/test_skill_commands_reload.py (9 cases)
* tests/cli/test_cli_reload_skills.py (3 cases)
* tests/gateway/test_reload_skills_command.py (4 cases)
Use case: NemoClaw / OpenShell-style sandboxed orchestrators that drop
skills into ~/.hermes/skills mid-session, plus agentic flows where the
agent itself installs a skill via the shell tool and needs it bound
without a gateway restart. The Python helper
clear_skills_system_prompt_cache(clear_snapshot=True) already exists
internally — this PR just exposes it via slash command and tool.
Detect leaked SGR mouse-report fragments in CLI input, strip them, and reset terminal modes in-place so scroll and typing recover without reopening the tab. Add regression tests for escaped, visible, and bare leak forms.
Adds Vercel Sandbox as a supported Hermes terminal backend alongside
existing providers (Local, Docker, Modal, SSH, Daytona, Singularity).
Uses the Vercel Python SDK to create/manage cloud microVMs, supports
snapshot-based filesystem persistence keyed by task_id, and integrates
with the existing BaseEnvironment shell contract and FileSyncManager
for credential/skill syncing.

Fixes#6672
Memory providers now receive on_session_switch() whenever AIAgent.session_id
rotates mid-process — /resume, /branch, /reset, /new, and context
compression. Before this, providers that cached per-session state in
initialize() (Hindsight's _session_id, _document_id, accumulated
_session_turns, _turn_counter) kept writing into the old session's
record after the agent had moved on.
MemoryProvider ABC
------------------
- New optional hook on_session_switch(new_session_id, *,
parent_session_id='', reset=False, **kwargs) with no-op default for
backward compat. reset=True signals /reset or /new — providers should
flush accumulated per-session buffers. reset=False for /resume,
/branch, compression where the logical conversation continues.
MemoryManager
-------------
- on_session_switch() fans the hook out to every registered provider.
Isolated try/except per provider — one bad provider can't block others.
- Empty/None new_session_id is a no-op to avoid corrupting provider state
during shutdown paths.
run_agent.py
------------
- _sync_external_memory_for_turn now passes session_id=self.session_id
into sync_all() and queue_prefetch_all(). Providers with defensive
session_id updates in sync_turn (Hindsight already had this at
plugins/memory/hindsight/__init__.py:1199) now actually receive the
current id.
- Compression block at ~L8884 already notified the context engine of
the rollover; now also calls
_memory_manager.on_session_switch(reason='compression').
cli.py
------
- new_session() fires reset=True, reason='new_session' so providers
flush buffers.
- _handle_resume_command fires reset=False, reason='resume' with the
previous session as parent_session_id.
- _handle_branch_command fires reset=False, reason='branch' with the
parent session_id already captured for the DB parent link.
gateway/run.py
--------------
- _handle_resume_command now evicts the cached AIAgent, mirroring
/branch and /reset. The next message rebuilds a fresh agent whose
memory provider initialize() runs with the correct session_id —
matches the pattern the gateway already uses for provider state
cross-session transitions.
Hindsight reference implementation
----------------------------------
- plugins/memory/hindsight/__init__.py adds on_session_switch that:
updates _session_id, mints a fresh _document_id (prevents
vectorize-io/hindsight#1303 overwrite), and clears _session_turns /
_turn_counter / _turn_index so in-flight batches don't flush under
the new document id. parent_session_id only overwritten when provided
(avoids clobbering on a bare switch).
Tests
-----
- tests/agent/test_memory_session_switch.py: new dedicated file. ABC
default no-op, manager fan-out, failure isolation, empty-id no-op,
session_id propagation through sync_all/queue_prefetch_all, Hindsight
state transitions for every reset/non-reset case, parent preservation.
- tests/cli/test_branch_command.py: new test verifying /branch fires
the hook with correct parent_session_id + reset=False + reason.
- tests/gateway/test_resume_command.py: new test verifying /resume
evicts the cached agent.
- tests/run_agent/test_memory_sync_interrupted.py: updated existing
assertions to account for the session_id kwarg on sync_all and
queue_prefetch_all.
E2E verified (real imports, tmp HERMES_HOME):
- /resume: session_id updates, doc_id fresh, buffers cleared, parent set
- /branch: session_id forks, parent links to original
- /new: reset=True clears accumulated state
- compression: reason='compression' propagated, lineage preserved
- Empty id: no-op, state preserved
- Legacy provider without on_session_switch: no crash
Reported by @nicoloboschi (Hindsight maintainer); related scope-widening
comment by @kidonng extending coverage to compression.
Add opt-in terminal.docker_run_as_host_user config flag that passes
--user $(id -u):$(id -g) to the Docker backend so files written into
bind-mounted directories (/workspace, /root, docker_volumes entries) are
owned by the host user instead of root.
When enabled on POSIX platforms, also drops SETUID/SETGID caps since the
container no longer needs gosu/su to switch users. Falls back cleanly on
platforms without os.getuid (e.g. native Windows Docker) with a warning.
Wired through all three config.yaml -> TERMINAL_* env-var bridges:
- cli.py env_mappings (CLI + TUI startup)
- gateway/run.py _terminal_env_map (gateway / messaging platforms)
- hermes_cli/config.py _config_to_env_sync (`hermes config set`)
Also fixes docker_mount_cwd_to_workspace silently failing in gateway
mode -- it was missing from gateway/run.py's _terminal_env_map.
Adds tests/tools/test_terminal_config_env_sync.py to guard against
future drift between the three bridges (same bug class shipped twice
in one month).
Bundled Hermes image won't work with this flag since its entrypoint
expects to start as root for the usermod/gosu hermes flow; works with
the default nikolaik/python-nodejs image and plain Debian/Ubuntu.
Adds the Curator — an auxiliary-model background task that periodically
reviews AGENT-CREATED skills and keeps the collection tidy: tracks usage,
transitions unused skills through active → stale → archived, and spawns
a forked AIAgent to consolidate overlaps and patch drift.
Default: enabled, inactivity-triggered (no cron daemon). Runs on CLI
startup and gateway boot when the last run is older than interval_hours
(default 24) AND the agent has been idle for min_idle_hours (default 2).
Invariants (all load-bearing):
- Never touches bundled or hub-installed skills (.bundled_manifest +
.hub/lock.json double-filter)
- Never auto-deletes — archive only. Archives are recoverable
via `hermes curator restore <skill>`
- Pinned skills bypass all auto-transitions
- Uses the aux client; never touches the main session's prompt cache
New files:
- tools/skill_usage.py — sidecar .usage.json telemetry, atomic writes,
provenance filter
- agent/curator.py — orchestrator: config, idle gating, state-machine
transitions (pure, no LLM), forked-agent review prompt
- hermes_cli/curator.py — `hermes curator {status,run,pause,resume,
pin,unpin,restore}` subcommand
- tests/tools/test_skill_usage.py — 29 tests
- tests/agent/test_curator.py — 25 tests
Modified files (surgical patches):
- tools/skills_tool.py — bump view_count on successful skill_view
- tools/skill_manager_tool.py — bump patch_count on skill_manage
patch/edit/write_file/remove_file; forget record on delete
- hermes_cli/config.py — add curator: section to DEFAULT_CONFIG
- hermes_cli/commands.py — add /curator CommandDef with subcommands
- hermes_cli/main.py — register `hermes curator` subparser via
register_cli() from hermes_cli.curator
- cli.py — /curator slash-command dispatch + startup hook
- gateway/run.py — gateway-boot hook (mirrors CLI)
Validation:
- 54 new tests across skill_usage + curator, all passing in 3s
- 346 tests across all touched files' neighbors green
- 2783 tests across hermes_cli/ + gateway/test_run_progress_topics.py green
- CLI smoke: `hermes curator status/pause/resume` work end-to-end
Companion to PR #16026 (class-first skill review prompt) — together
they form a loop: the review prompt stops near-duplicate skill creation
at the source, and the curator prunes/consolidates what still accumulates.
Refs #7816.
* Reject unsupported schemes (anything outside http/https/ws/wss) in
cli.py /browser connect before probing or persisting, matching the
gateway's existing 4015 path.
* Defend gateway browser.manage against `{"url": null}` and
non-string urls: empty/null falls back to DEFAULT_BROWSER_CDP_URL,
non-string returns a 4015 instead of slipping into the generic
5031 catch via TypeError on `"://" in url`.
* Add regression tests for both null-url fallback and non-string
rejection.
Fixes from Copilot's two passes on PR #17238:
* Validate parsed URL once: reject missing host, invalid port, and
unsupported scheme up front so malformed inputs (e.g. http://:9222
or http://localhost:abc) don't fall through to a generic 5031.
* Tighten _is_default_local_cdp to require a discovery-style path so
ws://127.0.0.1:9222/devtools/browser/<id> is not collapsed to bare
http://127.0.0.1:9222 (which would lose the path and break the
connect).
* Move browser.manage into _LONG_HANDLERS so the up-to-10s
launch-and-retry loop runs on the RPC pool instead of blocking the
main dispatcher.
* try_launch_chrome_debug uses Windows-appropriate detach kwargs
(creationflags=DETACHED_PROCESS|CREATE_NEW_PROCESS_GROUP) instead
of POSIX-only start_new_session=True.
* manual_chrome_debug_command uses subprocess.list2cmdline on
Windows so the printed instruction is cmd.exe-compatible.
* Mirror host/port validation in cli.py /browser connect so the
classic CLI never persists an invalid BROWSER_CDP_URL.
Detect an actual Chrome/Chromium executable before printing a manual CDP launch command, including common WSL-mounted Windows browser paths, so /browser connect does not suggest google-chrome when it is unavailable.
Share Chrome CDP launch helpers between the classic CLI and TUI so default /browser connect uses loopback consistently, retries local Chrome launch, and reports a copyable manual-start command instead of claiming a dead connection.
* perf(startup): lazy-import OpenAI, Anthropic, Firecrawl, account_usage
Four heavy SDK/module imports are now deferred off the hot startup path.
Net savings on cold module imports:
cli 1200 → 958 ms (-242)
run_agent 1220 → 901 ms (-319)
tools.web_tools 711 → 423 ms (-288)
agent.anthropic_adapter 230 → 15 ms (-215)
agent.auxiliary_client 253 → 68 ms (-185)
Four independent changes in one PR since they all use the same pattern
and share the same risk profile (heavy SDK import → lazy proxy or
function-local import):
1. tools/web_tools.py:
'from firecrawl import Firecrawl' moved into _get_firecrawl_client(),
which is only called when backend='firecrawl'. Users on Exa/Tavily/
Parallel pay zero firecrawl cost.
2. cli.py + gateway/run.py:
'from agent.account_usage import ...' moved into the /limits handlers.
account_usage transitively pulls the OpenAI SDK chain; only needed
when the user runs /limits.
3. agent/anthropic_adapter.py:
'try: import anthropic as _anthropic_sdk' replaced with a cached
'_get_anthropic_sdk()' accessor. The three usage sites
(build_anthropic_client, build_anthropic_bedrock_client,
read_claude_code_credentials_from_keychain) now resolve via the
accessor. All pre-existing test patches of
'agent.anthropic_adapter._anthropic_sdk' keep working because the
accessor respects any value already in module globals.
4. agent/auxiliary_client.py AND run_agent.py:
'from openai import OpenAI' replaced with an '_OpenAIProxy()' module-
level object that looks like the OpenAI class but imports the SDK on
first call/isinstance check. This preserves:
- 15+ in-module OpenAI(...) construction sites in auxiliary_client
and the single site in run_agent's _create_openai_client (Python's
function-scope name lookup finds the proxy, forwards the call);
- 'patch("agent.auxiliary_client.OpenAI", ...)' and
'patch("run_agent.OpenAI", ...)' test patterns used by 28+ test
files (patch replaces the module attribute as usual).
Tried two alternatives first:
- 'from openai._client import OpenAI' — doesn't skip openai/__init__.py
(the audit's hypothesis here was wrong).
- Module-level __getattr__ — works for external access but Python
function-scope name resolution skips __getattr__, so in-module
OpenAI(...) calls NameError.
Note: 'openai' still loads on 'import cli' because
cli.py -> neuter_async_httpx_del() -> openai._base_client, and
run_agent.py -> code_execution_tool.py (module-level
build_execute_code_schema) -> _load_config() -> 'from cli import
CLI_CONFIG'. Deferring those is a separate, larger change — out of scope
for this PR. The savings above all come from avoiding the openai/*,
anthropic/*, and firecrawl/* top-level type-tree imports on paths that
don't need them.
Verified:
- 302/302 tests in tests/agent/{test_anthropic_adapter,
test_bedrock_1m_context, test_minimax_provider, test_anthropic_keychain}
pass. Two pre-existing failures on main unchanged.
- 106/106 tests/agent/test_auxiliary_client.py pass (1 pre-existing fail).
- 97/97 tests/run_agent/test_create_openai_client_kwargs_isolation.py,
test_plugin_context_engine_init.py, test_invalid_context_length_warning.py,
test_api_max_retries_config.py,
tests/hermes_cli/test_gemini_provider.py, test_ollama_cloud_provider.py
pass (1 pre-existing fail).
- Live hermes chat smoke: 2 turns + /model switch + tool calls, zero
errors in the 57-line agent.log window.
- Module-level import of run_agent + auxiliary_client + anthropic_adapter
no longer pulls 'anthropic' or 'firecrawl' at all.
* fix(gateway): restore top-level account_usage import for test-patch surface
CI caught two failures in tests/gateway/test_usage_command.py that I
missed locally:
AttributeError: 'module' object at gateway.run has no attribute 'fetch_account_usage'
The test uses monkeypatch.setattr('gateway.run.fetch_account_usage', ...)
to inject a fake account-fetch call. Moving the import inside the
handler deleted that module-level attribute, breaking the patch surface.
Restoring the top-level import in gateway/run.py gives up the ~230 ms
gateway-boot savings from that one lazy, but:
1. the gateway is a long-running daemon — boot cost is paid once per
install, not per turn;
2. the other four lazy-imports (firecrawl, openai, anthropic, cli's
account_usage) remain in place and still account for the bulk of
the savings reported in the PR body;
3. preserving the patch surface keeps the established
'gateway.run.fetch_account_usage' monkeypatch pattern working
without touching tests.
Verified: tests/gateway/test_usage_command.py — 8 passed, 0 failed.
Full targeted sweep (2336 tests across agent/gateway/hermes_cli/run_agent):
2332 passed, 4 failed — all 4 pre-existing on main.

Append a compact 'model · 68% · ~/projects/hermes' footer to the FINAL
message of each turn, disabled by default (display.runtime_footer.enabled).
Answers the Telegram-side parity ask: runtime context that the CLI status
bar already shows is now available in messaging replies when enabled.
Wiring:
- gateway/runtime_footer.py: resolve_footer_config + format_runtime_footer +
build_footer_line. Pure-function renderer; per-platform overrides under
display.platforms.<platform>.runtime_footer.
- gateway/run.py: appends footer to response right after reasoning prepend
so it lands only on the final message (never tool progress or streaming
chunks). When streaming already delivered the body (already_sent), the
footer is sent as a small trailing message instead.
- agent_result now exposes context_length alongside last_prompt_tokens so
the footer can compute the pct; both gateway return paths updated.
- /footer [on|off|status] slash command, wired in CLI (cli.py) and gateway
(gateway/run.py both running-agent bypass and main dispatch). Global
toggle only; per-platform overrides via config.yaml.
Graceful degradation:
- Missing context_length (unknown model) → pct field silently dropped
(no '?%' artifact).
- Empty final_response → no footer appended.
- Unknown field names in config → silently ignored.
Tests: 25-case unit suite (tests/gateway/test_runtime_footer.py) plus E2E
harness covering streaming vs non-streaming branches, per-platform override,
and the exact argument contract gateway/run.py uses.

_manual_compress() passed self.agent._cached_system_prompt to
_compress_context() as the system_message argument. _compress_context
calls _build_system_prompt(system_message), which appends system_message
to prompt_parts that already contain the agent identity block — causing
the identity to appear twice in the new session's system prompt
(20,957 -> 42,303 chars, +102% as reported in issue #15281).
Fix: pass None instead of _cached_system_prompt. _build_system_prompt(None)
rebuilds the system prompt correctly from scratch without appending a
pre-built prompt on top of the identity layers.
Fixes#15281
Background macOS desktop control via cua-driver MCP — does NOT steal the
user's cursor or keyboard focus, works with any tool-capable model.
Replaces the Anthropic-native `computer_20251124` approach from the
abandoned #4562 with a generic OpenAI function-calling schema plus SOM
(set-of-mark) captures so Claude, GPT, Gemini, and open models can all
drive the desktop via numbered element indices.
- `tools/computer_use/` package — swappable ComputerUseBackend ABC +
CuaDriverBackend (stdio MCP client to trycua/cua's cua-driver binary).
- Universal `computer_use` tool with one schema for all providers.
Actions: capture (som/vision/ax), click, double_click, right_click,
middle_click, drag, scroll, type, key, wait, list_apps, focus_app.
- Multimodal tool-result envelope (`_multimodal=True`, OpenAI-style
`content: [text, image_url]` parts) that flows through
handle_function_call into the tool message. Anthropic adapter converts
into native `tool_result` image blocks; OpenAI-compatible providers
get the parts list directly.
- Image eviction in convert_messages_to_anthropic: only the 3 most
recent screenshots carry real image data; older ones become text
placeholders to cap per-turn token cost.
- Context compressor image pruning: old multimodal tool results have
their image parts stripped instead of being skipped.
- Image-aware token estimation: each image counts as a flat 1500 tokens
instead of its base64 char length (~1MB would have registered as
~250K tokens before).
- COMPUTER_USE_GUIDANCE system-prompt block — injected when the toolset
is active.
- Session DB persistence strips base64 from multimodal tool messages.
- Trajectory saver normalises multimodal messages to text-only.
- `hermes tools` post-setup installs cua-driver via the upstream script
and prints permission-grant instructions.
- CLI approval callback wired so destructive computer_use actions go
through the same prompt_toolkit approval dialog as terminal commands.
- Hard safety guards at the tool level: blocked type patterns
(curl|bash, sudo rm -rf, fork bomb), blocked key combos (empty trash,
force delete, lock screen, log out).
- Skill `apple/macos-computer-use/SKILL.md` — universal (model-agnostic)
workflow guide.
- Docs: `user-guide/features/computer-use.md` plus reference catalog
entries.
44 new tests in tests/tools/test_computer_use.py covering schema
shape (universal, not Anthropic-native), dispatch routing, safety
guards, multimodal envelope, Anthropic adapter conversion, screenshot
eviction, context compressor pruning, image-aware token estimation,
run_agent helpers, and universality guarantees.
469/469 pass across tests/tools/test_computer_use.py + the affected
agent/ test suites.
- `model_tools.py` provider-gating: the tool is available to every
provider. Providers without multi-part tool message support will see
text-only tool results (graceful degradation via `text_summary`).
- Anthropic server-side `clear_tool_uses_20250919` — deferred;
client-side eviction + compressor pruning cover the same cost ceiling
without a beta header.
- macOS only. cua-driver uses private SkyLight SPIs
(SLEventPostToPid, SLPSPostEventRecordTo,
_AXObserverAddNotificationAndCheckRemote) that can break on any macOS
update. Pin with HERMES_CUA_DRIVER_VERSION.
- Requires Accessibility + Screen Recording permissions — the post-setup
prints the Settings path.
Supersedes PR #4562 (pyautogui/Quartz foreground backend, Anthropic-
native schema). Credit @0xbyt4 for the original #3816 groundwork whose
context/eviction/token design is preserved here in generic form.
When a paste takes longer than 500ms to process on the prompt_toolkit
event-loop thread, emit a logger.warning with elapsed time, byte size,
line count, and sys.platform. Gives us concrete repro data for the
recurring 'CLI freezes after paste on macOS' class of reports (issue
#16263, plus sibling reports across Claude Code / Cursor / Lightroom
against macOS Tahoe 26).
Pure diagnostic — no behavior change. Two time.perf_counter() calls
and one conditional per paste event. Log line only fires when the
handler is actually slow, so normal pastes add no log noise.
The gateway fix in the previous commit forwards _session_messages on
gateway session teardown. The CLI exit cleanup path had the same bug:
it read getattr(agent, 'conversation_history', None) or [] — but AIAgent
has no conversation_history attribute, so providers always received [].
Switch to _session_messages (same attribute the gateway now uses),
guarded by isinstance(..., list) to preserve the no-arg fallback for
MagicMock-based CLI test stubs.
Adds tests/cli/test_cli_shutdown_memory_messages.py (4 cases mirroring
the gateway suite).
* feat(image-input): native multimodal routing based on model vision capability
Attach user-sent images as OpenAI-style content parts on the user turn when
the active model supports native vision, so vision-capable models see real
pixels instead of a lossy text description from vision_analyze.
Routing decision (agent/image_routing.py::decide_image_input_mode):
agent.image_input_mode = auto | native | text (default: auto)
In auto mode:
- If auxiliary.vision.provider/model is explicitly configured, keep the
text pipeline (user paid for a dedicated vision backend).
- Else if models.dev reports supports_vision=True for the active
provider/model, attach natively.
- Else fall back to text (current behaviour).
Call sites updated: gateway/run.py (all messaging platforms), tui_gateway
(dashboard/Ink), cli.py (interactive /attach + drag-drop).
run_agent.py changes:
- _prepare_anthropic_messages_for_api now passes image parts through
unchanged when the model supports vision — the Anthropic adapter
translates them to native image blocks. Previous behaviour
(vision_analyze → text) only runs for non-vision Anthropic models.
- New _prepare_messages_for_non_vision_model mirrors the same contract
for chat.completions and codex_responses paths, so non-vision models
on any provider get text-fallback instead of failing at the provider.
- New _model_supports_vision() helper reads models.dev caps.
vision_analyze description rewritten: positions it as a tool for images
NOT already visible in the conversation (URLs, tool output, deeper
inspection). Prevents the model from redundantly calling it on images
already attached natively.
Config default: agent.image_input_mode = auto.
Tests: 35 new (test_image_routing.py + test_vision_aware_preprocessing.py),
all existing tests that reference _prepare_anthropic_messages_for_api
still pass (198 targeted + new tests green).
* feat(image-input): size-cap + resize oversized images, charge image tokens in compressor
Two follow-ups that make the native image routing safer for long / heavy
sessions:
1) Oversize handling in build_native_content_parts:
- 20 MB ceiling per image (matches vision_tools._MAX_BASE64_BYTES,
the most restrictive provider — Gemini inline data).
- Delegates to vision_tools._resize_image_for_vision (Pillow-based,
already battle-tested) to downscale to 5 MB first-try.
- If Pillow is missing or resize still overshoots, the image is
dropped and reported back in skipped[]; caller falls back to text
enrichment for that image.
2) Image-token accounting in context_compressor:
- New _IMAGE_TOKEN_ESTIMATE = 1600 (matches Claude Code's constant;
within the realistic range for Anthropic/GPT-4o/Gemini billing).
- _content_length_for_budget() helper: sums text-part lengths and
charges _IMAGE_CHAR_EQUIVALENT (1600 * 4 chars) per image/image_url/
input_image part. Base64 payload inside image_url is NOT counted
as chars — dimensions don't matter, only image-presence.
- Both tail-cut sites (_prune_old_tool_results L527 and
_find_tail_cut_by_tokens L1126) now call the helper so multi-image
conversations don't slip past compression budget.
Tests: 9 new in test_image_routing.py (oversize triggers resize,
resize-fails-returns-None, oversize-skipped-reported), 11 new in
test_compressor_image_tokens.py (flat charge per image, multiple images,
Responses-API / Anthropic-native / OpenAI-chat shapes, no-inflation on
raw base64, bounds-check on the constant, integration test that an
image-heavy tail actually gets trimmed).
* fix(image-input): replace blanket 20MB ceiling with empirically-verified per-provider limits
The previous commit imposed a hardcoded 20 MB base64 ceiling on all
providers, triggering auto-resize on anything larger. This was wrong in
both directions:
* Too loose for Anthropic — actual limit is 5 MB (returns HTTP 400
'image exceeds 5 MB maximum' above that).
* Too strict for OpenAI / Codex / OpenRouter — accept 49 MB+ without
complaint (empirically verified April 2026 with progressive PNG
sizes).
New behaviour:
* _PROVIDER_BASE64_CEILING table: only anthropic and bedrock have a
ceiling (5 MB, since bedrock-on-Claude shares Anthropic's decoder).
* Providers NOT in the table get no ceiling — images attach at native
size and we trust the provider to return its own error if it
disagrees. A provider-specific 400 message is clearer than us
guessing wrong and silently degrading image quality.
* build_native_content_parts() gains a keyword-only provider arg;
gateway/CLI/TUI pass the active provider so Anthropic users get
auto-resize protection while OpenAI users don't pay it.
* Resize target dropped from 5 MB to 4 MB to slide safely under
Anthropic's boundary with header overhead.
Empirical measurements (direct API, no Hermes in the loop):
image b64 anthropic openrouter/gpt5.5 codex-oauth/gpt5.5
0.19 MB ✓ ✓ ✓
12.37 MB ✗ 400 5MB ✓ ✓
23.85 MB ✗ 400 5MB ✓ ✓
49.46 MB ✗ 413 ✓ ✓
Tests: rewrote TestOversizeHandling (5 tests): no-ceiling pass-through,
Anthropic resize fires, Anthropic skip on resize-fail, build_native_parts
routes ceiling by provider, unknown provider gets no ceiling. All 52
targeted tests pass.
* refactor(image-input): attempt native, shrink-and-retry on provider reject
Replace proactive per-provider size ceilings with a reactive shrink path
on the provider's actual rejection. All providers now attempt native
full-size attachment first; if the provider returns an image-too-large
error, the agent silently shrinks and retries once.
Why the previous design was wrong: hardcoding provider ceilings
(anthropic=5MB, others=unlimited) meant OpenAI users on a 10MB image
paid no tax, but Anthropic users lost quality on anything >5MB even
though the empirical behaviour at provider-reject time is the same
(shrink + retry). Baking the table into the routing layer also
requires updating Hermes every time a provider's limit changes.
Reactive design:
- image_routing.py: _file_to_data_url encodes native size, no ceiling.
build_native_content_parts drops its provider kwarg.
- error_classifier.py: new FailoverReason.image_too_large + pattern
match ("image exceeds", "image too large", etc.) checked BEFORE
context_overflow so Anthropic's 5MB rejection lands in the right
bucket.
- run_agent.py: new _try_shrink_image_parts_in_messages walks api
messages in-place, re-encodes oversized data: URL image parts
through vision_tools._resize_image_for_vision to fit under 4MB,
handles both chat.completions (dict image_url) and Responses
(string image_url) shapes, ignores http URLs (provider-fetched).
New image_shrink_retry_attempted flag in the retry loop fires the
shrink exactly once per turn after credential-pool recovery but
before auth retries.
E2E verified live against Anthropic claude-sonnet-4-6:
- 17.9MB PNG (23.9MB b64) attached at native size
- Anthropic returns 400 "image exceeds 5 MB maximum"
- Agent logs '📐 Image(s) exceeded provider size limit — shrank and
retrying...'
- Retry succeeds, correct response delivered in 6.8s total.
Tests: 12 new (8 shrink-helper shapes + 4 classifier signals),
replaces 5 proactive-ceiling tests with 3 simpler 'native attach works'
tests. 181 targeted tests pass. test_enum_members_exist in
test_error_classifier.py updated for the new enum value.
The CLI renders through prompt_toolkit in non-full-screen mode, so every
repaint uses the renderer's tracked _cursor_pos.y to cursor_up() + erase
before drawing the new frame. Any time that tracked position drifts from
terminal reality, redraws stack on top of stale content instead of
overwriting it. Four user-visible bugs share this root cause.
Fixes:
- #5474 (SIGWINCH ghosts): the resize wrapper previously only handled
column-shrink reflow. Generalize it to force a full screen-clear
(erase_screen + cursor_goto(0,0)) and renderer.reset() on every resize
— covers widen, row-shrink, and multiplexer SIGWINCH-less redraws.
- #8688 (cmux/tmux tab switch): no SIGWINCH fires on focus regain, so
prompt_toolkit has no signal to recover. Add a _force_full_redraw()
helper, bound to Ctrl+L (standard bash/zsh/vim convention) and exposed
as /redraw. Users can manually clear drift without restarting Hermes.
- #14692 (DSR response leaks — ^[[53;1R): resize storms make
prompt_toolkit's CSI 6n queries race past the input parser; the
terminal's reply ends up as literal input text. Add a sibling of the
bracketed-paste sanitizer that strips \x1b[<row>;<col>R and the
caret-escape visible form from paste text, buffer text-filter, and
the input-processing loop.
The idle-redraw removal (#12641) is in the preceding commit from
@foxion37 — keeping them as separate commits preserves attribution.
Closes#15775.
Title generation swallowed exceptions at debug level and returned None,
so a depleted auxiliary provider (e.g. OpenRouter 402) silently left
sessions with NULL titles. Reporter observed 45 untitled sessions
accumulated over 19 days with no user-visible indication.
- agent/title_generator.py: accept optional failure_callback, bump log
to WARNING, invoke callback on call_llm exception (swallowing callback
errors so nothing can crash the fire-and-forget worker thread).
- cli.py, gateway/run.py: pass agent._emit_auxiliary_failure as the
callback so failures route through the existing user-visible warning
channel.
- tests: cover callback fires / errors are swallowed / no-callback
legacy behavior / maybe_auto_title forwards kwarg to worker.
Two related fixes for OpenClaw-residue problems after an OpenClaw→Hermes
migration (especially migrations done via OpenClaw's own tool, which
doesn't archive the source directory).
1. optional-skills/migration/openclaw-migration/scripts/openclaw_to_hermes.py:
rebrand_text() was rewriting ~/.openclaw/config.yaml → ~/.Hermes/config.yaml
(capital H — a directory that doesn't exist). Now case-preserving:
"OpenClaw" → "Hermes" (prose), but "openclaw" → "hermes" (so filesystem
paths land on the real Hermes home). Regex logic unchanged — replacement
function now checks if the matched text was all-lowercase and emits the
replacement in the matching case.
2. agent/onboarding.py + cli.py: one-time startup banner the first time
Hermes launches and finds ~/.openclaw/. Tells the user to run
`hermes claw cleanup` to archive it, gated on the existing onboarding
seen-flag framework (onboarding.seen.openclaw_residue_cleanup in
config.yaml). Fires once per install; re-running requires wiping that
flag or running cleanup directly.
Tests:
- 4 new TestDetectOpenclawResidue tests (present / absent / file-instead-
of-dir / default-home smoke)
- 2 TestOpenclawResidueHint tests (content check)
- 2 TestOpenclawResidueSeenFlag tests (flag isolation + round-trip)
- test_rebrand_text_preserves_filesystem_path_casing regression test
with 4 scenarios including the exact ~/.openclaw/config.yaml case
- Existing test_rebrand_text_* tests updated to the new case-preserving
contract (lowercase input → lowercase output)

Every working dir hermes ever touches gets its own shadow git repo under
~/.hermes/checkpoints/{sha256(abs_dir)[:16]}/. The per-repo _prune is a
no-op (comment in CheckpointManager._prune says so), so abandoned repos
from deleted/moved projects or one-off tmp dirs pile up forever. Field
reports put the typical offender at 1000+ repos / ~12 GB on active
contributor machines.
Adds an opt-in startup sweep that mirrors the sessions.auto_prune
pattern from #13861 / #16286:
- tools/checkpoint_manager.py: new prune_checkpoints() and
maybe_auto_prune_checkpoints() helpers. Deletes shadow repos that
are orphan (HERMES_WORKDIR marker points to a path that no longer
exists) or stale (newest in-repo mtime older than retention_days).
Idempotent via a CHECKPOINT_BASE/.last_prune marker file so it only
runs once per min_interval_hours regardless of how many hermes
processes start up.
- hermes_cli/config.py: new checkpoints.auto_prune /
retention_days / delete_orphans / min_interval_hours knobs.
Default auto_prune: false so users who rely on /rollback against
long-ago sessions never lose data silently.
- cli.py / gateway/run.py: startup hooks gated on checkpoints.auto_prune,
called right next to the existing state.db maintenance block.
- Docs updated with the new config knobs.
- 11 regression tests: orphan/stale deletion, precedence, byte-freed
tracking, non-shadow dir skip, interval gating, corrupt marker
recovery.
Refs #3015 (session-file disk growth was fixed in #16286; this covers
the checkpoint side noted out-of-scope there).
Four independent session-UX bugs reported by an external user (#16294).
/save wrote hermes_conversation_<ts>.json to CWD — invisible to
'hermes sessions browse' and easy to lose. Snapshots now write under
~/.hermes/sessions/saved/ and the command prints the absolute path plus
a 'hermes --resume <id>' hint for the live DB-indexed session.
'hermes sessions browse' default --limit raised from 50 to 500. With the
old ceiling, users with moderately long histories saw only the most
recent 50 rows and assumed older sessions had been lost.
TUI session.list (`/resume` picker) switched from a hardcoded allow-list
of 13 gateway source names to a deny-list of just { 'tool' }. Sessions
tagged acp / webhook / user-defined HERMES_SESSION_SOURCE values and
any newly-added platform now surface. Default limit 20 → 200.
ollama-cloud provider setup passes force_refresh=True to
fetch_ollama_cloud_models() so a user entering their API key sees the
fresh catalog (e.g. deepseek v4 flash, kimi k2.6) immediately instead
of waiting up to an hour for the disk cache TTL to expire.
Closes#16294.
`delete_session()` and `prune_sessions()` only removed SQLite records,
leaving .json/.jsonl transcript files on disk forever. Over time this
causes unbounded disk growth (~27MB/day observed).
Changes:
- Add `_remove_session_files()` static helper that cleans up
`{session_id}.json`, `.jsonl`, and `request_dump_{session_id}_*.json`
- `delete_session()` accepts optional `sessions_dir` param and removes
files for the deleted session and its children
- `prune_sessions()` accepts optional `sessions_dir` param and removes
files for all pruned sessions after the DB transaction
- Wire up CLI `hermes sessions delete` and `hermes sessions prune` to
pass `sessions_dir`
- File cleanup is best-effort (OSError silenced) so DB operations are
never blocked by filesystem issues
- Fully backward-compatible: `sessions_dir=None` (default) preserves
existing behavior
Enter while the agent is busy can now inject the typed text via /steer —
arriving at the agent after the next tool call — instead of interrupting
(current default) or queueing for the next turn.
Changes:
- cli.py: keybinding honors busy_input_mode='steer' by calling
agent.steer(text) on the UI thread (thread-safe), with automatic
fallback to 'queue' when the agent is missing, steer() is unavailable,
images are attached, or steer() rejects the payload. /busy accepts
'steer' as a fourth argument alongside queue/interrupt/status.
- gateway/run.py: busy-message handler and the PRIORITY running-agent
path both route through running_agent.steer() when the mode is 'steer',
with the same fallback-to-queue safety net. Ack wording tells users
their message was steered into the current run. Restart-drain queueing
now also activates for 'steer' so messages aren't lost across restarts.
- agent/onboarding.py: first-touch hint has a steer branch for both
CLI and gateway.
- hermes_cli/commands.py: /busy args_hint updated to include steer,
and 'steer' is registered as a subcommand (completions).
- hermes_cli/web_server.py: dashboard select widget offers steer.
- hermes_cli/config.py, cli-config.yaml.example, hermes_cli/tips.py:
inline docs updated.
- website/docs/user-guide/cli.md + messaging/index.md: documented.
- Tests: steer set/status path for /busy; onboarding hints;
_load_busy_input_mode accepts steer; busy-session ack exercises
steer success + two fallback-to-queue branches.
Requested on X by @CodingAcct.
Default is unchanged (interrupt).
* fix(/branch): redirect session_log_file and expose branch sessions in list
Two bugs when using /branch:
1. cli.py _handle_branch_command updated agent.session_id but not
agent.session_log_file, so all messages written after branching
landed in the original session's JSON file and the branch never
got its own session_{id}.json on disk.
Fix: mirror the compression-split path (run_agent.py:7579) and
update session_log_file immediately after changing session_id.
2. hermes_state.py list_sessions_rich filtered out every session
with parent_session_id IS NOT NULL to hide sub-agent runs and
compression continuations. Branch sessions share this column, so
they became invisible to `hermes sessions list` and `sessions browse`.
Fix: also include branch children — those whose parent ended with
end_reason='branched' AND whose started_at >= parent.ended_at
(the same timing condition that get_compression_tip uses to
distinguish continuations from live-spawned subagents).

New `hermes kanban` CLI subcommand + `/kanban` slash command + skills for
worker and orchestrator profiles. SQLite-backed task board
(~/.hermes/kanban.db) shared across all profiles on the host. Zero
changes to run_agent.py, no new core tools, no tool-schema bloat.
Motivation: delegate_task is a function call — sync fork/join, anonymous
subagent, no resumability, no human-in-the-loop. Kanban is the durable
shape needed for research triage, scheduled ops, digital twins,
engineering pipelines, and fleet work. They coexist (workers may call
delegate_task internally).
What this adds
- hermes_cli/kanban_db.py — schema, CAS claim, dependency resolution,
dispatcher, workspace resolution, worker-context builder.
- hermes_cli/kanban.py — 15-verb CLI surface and shared run_slash()
entry point used by both CLI and gateway.
- skills/devops/kanban-worker — how a profile should work a claimed task.
- skills/devops/kanban-orchestrator — "you are a dispatcher, not a
worker" template with anti-temptation rules.
- /kanban slash command wired into cli.py and gateway/run.py. Bypasses
the running-agent guard (board writes don't touch agent state), so
/kanban unblock can free a stuck worker mid-conversation.
- Design spec at docs/hermes-kanban-v1-spec.pdf — comparative analysis
vs Cline Kanban, Paperclip, NanoClaw, Gemini Enterprise; 8 patterns;
4 user stories; implementation plan; concurrency correctness.
- Docs: website/docs/user-guide/features/kanban.md, CLI reference
updated, sidebar entry added.
Architecture highlights
- Three planes: control (user + gateway), state (board + dispatcher),
execution (pool of profile processes).
- Every worker is a full OS process, spawned as `hermes -p <profile>`.
No in-process subagent swarms — solves NanoClaw's SDK-lifecycle
failure class.
- Atomic claim via SQLite CAS in a BEGIN IMMEDIATE transaction; stale
claims reclaimed 15 min after their TTL expires.
- Tenant namespacing via one nullable column — one specialist fleet
can serve many businesses with data isolation by workspace path.
Tests: 60 targeted tests (schema, CAS atomicity, dependency resolution,
dispatcher, workspace kinds, tenancy, CLI + slash surface). All pass
hermetic via scripts/run_tests.sh.
The ephemeral no-tools side-question variant of /btw confused users who
expected 'by-the-way' to mean 'run this off to the side with tools' —
they'd type /btw and get a toolless agent that couldn't do the work.
/bg worked because it was /background with full tools.
Collapse the two: /btw and /bg both alias to /background. One command,
one behavior, no more gotchas about which variant has tools.
Removed:
- _handle_btw_command in cli.py and gateway/run.py
- _run_btw_task + _active_btw_tasks state in gateway/run.py
- prompt.btw JSON-RPC method + btw.complete event in tui_gateway
- BtwStartResponse type + btw.complete case in ui-tui
- Standalone /btw slash tree registration in Discord
- Standalone btw CommandDef in hermes_cli/commands.py
Updated:
- background CommandDef aliases: (bg,) -> (bg, btw)
- TUI session.ts: local btw handler merged into background
- Docs and tips updated to describe /btw as a /background alias
Instead of a blocking first-run questionnaire, show a one-time hint the first
time the user hits each behavior fork:
1. First message while the agent is working — appends a hint to the busy-ack
explaining the /busy queue vs /busy interrupt knob, phrased to match the
mode that was just applied (don't tell a queue-mode user to switch to
queue).
2. First tool that runs for >= 30s in the noisiest progress mode
(tool_progress: all) — prints a hint about /verbose to cycle display
modes (all -> new -> off -> verbose). Gated on /verbose actually being
usable on the surface: always shown on CLI; on gateway only shown when
display.tool_progress_command is enabled.
Each hint is latched in config.yaml under onboarding.seen.<flag>, so it
fires exactly once per install across CLI, gateway, and cron, then never
again. Users can wipe the section to re-see hints.
New:
- agent/onboarding.py — is_seen / mark_seen / hint strings, shared by
both CLI and gateway.
- onboarding.seen in DEFAULT_CONFIG (hermes_cli/config.py) and in
load_cli_config defaults (cli.py). No _config_version bump — deep
merge handles new keys.
Wired:
- gateway/run.py: _handle_active_session_busy_message appends the hint
after building the ack. progress_callback tracks tool.completed
duration and queues the tool-progress hint into the progress bubble.
- cli.py: CLI input loop appends the busy-input hint on the first busy
Enter; _on_tool_progress appends the tool-progress hint on the first
>=30s tool completion. In-memory CLI_CONFIG is also updated so
subsequent fires in the same process are suppressed immediately.
All writes go through atomic_yaml_write and are wrapped in try/except
so onboarding can never break the input/busy-ack paths.
`_apply_model_switch_result` (the interactive `/model` picker's
confirmation path) printed `ModelInfo.context_window` straight from
models.dev, which reports the vendor-wide value (1.05M for gpt-5.5 on
openai). ChatGPT Codex OAuth caps the same slug at 272K, so the picker
showed 1M while the runtime (compressor, gateway `/model`, typed
`/model <name>`) correctly used 272K — the classic 'sometimes 1M,
sometimes 272K' mismatch on a single model.
Both display paths now go through `resolve_display_context_length()`,
matching the fix that `_handle_model_switch` received earlier.
Also bump the stale last-resort fallback in DEFAULT_CONTEXT_LENGTHS
(`gpt-5.5: 400000 -> 1050000`) to match the real OpenAI API value; the
272K Codex cap is already enforced via the Codex-OAuth branch, so the
fallback now reflects what every non-Codex probe-miss should see.
Tests: adds `test_apply_model_switch_result_context.py` with three
scenarios (Codex cap wins, OpenRouter shows 1.05M, resolver-empty falls
back to ModelInfo). Updates the existing non-Codex fallback test to
assert 1.05M (the correct value).
## Validation
| path | before | after |
|-------------------------------|-----------|-----------|
| picker -> gpt-5.5 on Codex | 1,050,000 | 272,000 |
| picker -> gpt-5.5 on OpenAI | 1,050,000 | 1,050,000 |
| picker -> gpt-5.5 on OpenRouter | 1,050,000 | 1,050,000 |
| typed /model gpt-5.5 on Codex | 272,000 | 272,000 |
When the user interrupts a long-running task, prompt_toolkit tries to
flush stdout during emergency shutdown. If stdout is in a broken state
(redirected to /dev/null, pipe closed, terminal gone), the flush raises
`OSError: [Errno 5] Input/output error` which propagates unhandled and
crashes the CLI.
Two defense layers:
1. `_suppress_closed_loop_errors`: add `OSError` with `errno.EIO` to
the asyncio exception handler, matching the existing pattern for
`RuntimeError("Event loop is closed")` and `KeyError("is not
registered")`.
2. Outer `except (KeyError, OSError)` block: add `errno.EIO` check
before the existing string-match guards, silently suppressing the
error instead of printing a misleading stdin-related message.
Fixes#13710.
Base CLI's editor UX was better because prompt_toolkit picks the system
editor first, then friendly terminal editors before vi. Do not override
that with a vim-first chain.
Keep the CLI on prompt_toolkit's picker and only set tempfile_suffix='.md'
to avoid the complex-tempfile EEXIST path. Update the TUI resolver to
match prompt_toolkit's fallback order: $VISUAL, $EDITOR, editor, nano,
pico, vi, emacs.
Setting buffer.tempfile = 'prompt.md' pushed prompt_toolkit into its
complex-tempfile path, which creates a temp dir and then calls
os.makedirs() on that same path when no subdirectory is present. That
raises EEXIST before the editor can launch.
Keep prompt_toolkit on the simple tempfile path with .md suffix, and
make the editor fallback chain explicit on both surfaces:
$VISUAL -> $EDITOR -> nvim -> vim -> vi -> nano.
prompt_toolkit's default editor list is: $VISUAL, $EDITOR, /usr/bin/editor,
/usr/bin/nano, /usr/bin/pico, /usr/bin/vi, /usr/bin/emacs — so when
neither env var is set, the base CLI launched nano. The TUI fell back
to a literal 'vi'. Same Ctrl+G keystroke, two different editors.
Pick the same chain on both surfaces:
$VISUAL → $EDITOR → vim → vi → nano
CLI: override input_area.buffer._open_file_in_editor on the TextArea
once at app build time. Local to that buffer; doesn't touch
os.environ or affect other subprocesses.
TUI: extract resolveEditor() into ui-tui/src/lib/editor.ts. PATH walk
with accessSync(X_OK), no shelling out. Six-line unit test verifies
the priority order and the multi-entry PATH walk.
Base CLI was handing prompt_toolkit's Buffer.open_in_editor() a default
config — Buffer.tempfile_suffix and .tempfile both empty — so it
created /tmp/tmpXXXXXX with no extension. nano/vim/helix all key
syntax highlighting off the file extension, so the buffer rendered
plain.
The TUI already writes to <mkdtemp>/prompt.md and gets full markdown
highlighting + a sensible title bar. Set buffer.tempfile = 'prompt.md'
on the TextArea so prompt_toolkit's complex-tempfile path produces
<mkdtemp>/prompt.md to match. shutil.rmtree cleanup is built-in.
When switching models on a custom endpoint (ollama-launch):
- Same-provider switches no longer re-resolve credentials (fixes base_url
being lost for 'custom' provider on subsequent switches)
- Named providers (ollama-launch) are resolved via user_providers so
switch_model can find their base_url from config
- Models not in the /v1/models probe but present in the user's saved
provider config are accepted with a warning instead of rejected
- CLI /model and TUI /model both pass user_providers/custom_providers
to switch_model so the config model list is available for validation
Closes#15088
Same problem as the TUI: Cursor and VSCode bind Ctrl+G to "Find Next"
at the editor level, so the keystroke never reaches the terminal and
the prompt_toolkit-driven Hermes CLI sees nothing.
Register ('escape', 'g') alongside the existing 'c-g' on the same
handler so the editor handoff works inside Cursor/VSCode too. The
filter (no clarify/approval/sudo/secret prompt active) is unchanged.
The AIAgent.flush_memories pre-compression save, the gateway
_flush_memories_for_session, and everything feeding them are
obsolete now that the background memory/skill review handles
persistent memory extraction.
Problems with flush_memories:
- Pre-dates the background review loop. It was the only memory-save
path when introduced; the background review now fires every 10 user
turns on CLI and gateway alike, which is far more frequent than
compression or session reset ever triggered flush.
- Blocking and synchronous. Pre-compression flush ran on the live agent
before compression, blocking the user-visible response.
- Cache-breaking. Flush built a temporary conversation prefix
(system prompt + memory-only tool list) that diverged from the live
conversation's cached prefix, invalidating prompt caching. The
gateway variant spawned a fresh AIAgent with its own clean prompt
for each finalized session — still cache-breaking, just in a
different process.
- Redundant. Background review runs in the live conversation's
session context, gets the same content, writes to the same memory
store, and doesn't break the cache. Everything flush_memories
claimed to preserve is already covered.
What this removes:
- AIAgent.flush_memories() method (~248 LOC in run_agent.py)
- Pre-compression flush call in _compress_context
- flush_memories call sites in cli.py (/new + exit)
- GatewayRunner._flush_memories_for_session + _async_flush_memories
(and the 3 call sites: session expiry watcher, /new, /resume)
- 'flush_memories' entry from DEFAULT_CONFIG auxiliary tasks,
hermes tools UI task list, auxiliary_client docstrings
- _memory_flush_min_turns config + init
- #15631's headroom-deduction math in
_check_compression_model_feasibility (headroom was only needed
because flush dragged the full main-agent system prompt along;
the compression summariser sends a single user-role prompt so
new_threshold = aux_context is safe again)
- The dedicated test files and assertions that exercised
flush-specific paths
What this renames (with read-time backcompat on sessions.json):
- SessionEntry.memory_flushed -> SessionEntry.expiry_finalized.
The session-expiry watcher still uses the flag to avoid re-running
finalize/eviction on the same expired session; the new name
reflects what it now actually gates. from_dict() reads
'expiry_finalized' first, falls back to the legacy 'memory_flushed'
key so existing sessions.json files upgrade seamlessly.
Supersedes #15631 and #15638.
Tested: 383 targeted tests pass across run_agent/, agent/, cli/,
and gateway/ session-boundary suites. No behavior regressions —
background memory review continues to handle persistent memory
extraction on both CLI and gateway.
/model gpt-5.5 on openai-codex showed 'Context: 1,050,000 tokens' because
the display block used ModelInfo.context_window directly from models.dev.
Codex OAuth actually enforces 272K for the same slug, and the agent's
compressor already runs at 272K via get_model_context_length() — so the
banner + real context budget said 272K while /model lied with 1M.
Route the display context through a new resolve_display_context_length()
helper that always prefers agent.model_metadata.get_model_context_length
(which knows about Codex OAuth, Copilot, Nous caps) and only falls back
to models.dev when that returns nothing.
Fix applied to all 3 /model display sites:
cli.py _handle_model_switch
gateway/run.py picker on_model_selected callback
gateway/run.py text-fallback confirmation
Reported by @emilstridell (Telegram, April 2026).
Before this, typing during /compress was accepted by the classic CLI
prompt and landed in the next prompt after compression finished,
effectively consuming a keystroke for a prompt that was about to be
replaced. Wrapping the body in self._busy_command('Compressing
context...') blocks input rendering for the duration, matching the
pattern /skills install and other slow commands already use.
Salvages the useful part of #10303 (@iRonin). The `_compressing` flag
added to run_agent.py in the original PR was dead code (set in 3 spots,
read nowhere — not by cli.py, not by run_agent.py, not by the Ink TUI
which doesn't use _busy_command at all) and was dropped.
Follow-up to @iRonin's Ctrl+D EOF fix. If the input text is empty but
the user has pending attached images, do nothing rather than exiting —
otherwise a stray Ctrl+D silently discards the attachments.
