+Unified surface
+---------------
+One tool — ``image_generate`` — covers **text-to-image** and
+**image-to-image / image editing**. The router is the presence of
+``image_url`` (and/or ``reference_image_urls``): if any source image is

+omitted, the provider routes to text-to-image. Users pick one **model**
+(e.g. nano-banana-pro, gpt-image-2, grok-imagine-image); the provider
+handles which underlying endpoint to hit. This mirrors the ``video_gen``
+provider design (``agent/video_gen_provider.py``) so the two surfaces

+# one tool call per turn multiplies the number of round-trips — and therefore

+# assistant response collapses N turns into one, cutting both latency and the
+# resent-context cost that compounds over a long conversation.
+#
+# The hermes-agent runtime already executes a batch of tool calls
+# concurrently when they are independent (read-only tools always; path-scoped
+# file ops when their targets don't overlap — see
+# run_agent._execute_tool_calls / tool_dispatch_helpers). The missing piece
+# was telling the *model* to emit those calls together in the first place.

 The gateway dials **out** to the connector's `/relay` WebSocket for the
-handshake + outbound actions (§4) + its own `/stop` egress (§5). Inbound,
-however, is delivered the other way: the connector **POSTs** the normalized
-event to the gateway's inbound endpoint (`HttpGatewayDelivery` on the connector;
-`gateway/relay/inbound_receiver.py` on the gateway). The reason is
-multi-instance: the connector instance that owns a platform's socket (and thus
-produces inbound events) is generally **not** the instance a given gateway
-dialed its outbound WS into, so inbound must target a tenant **endpoint** (which
-may load-balance across gateway instances) rather than ride one gateway's
-outbound socket. Each delivery is HMAC-signed with the per-tenant **delivery
-key** (§6.1); the gateway verifies the signature over the exact raw bytes before
-accepting the event. Two POST targets:
+handshake + outbound actions (§4) + its own `/stop` egress (§5). Inbound rides
+the **same socket** in the other direction: the connector pushes an `inbound`
+frame (and `interrupt_inbound` for §5) down the gateway's outbound WS. There is
+**no gateway-side inbound HTTP endpoint** — a gateway need not (and, when hosted,
+cannot) expose any inbound port; everything flows over the connection it
+initiated.
+
+**Multi-instance routing.** The connector instance that owns a platform's socket
+(and thus produces inbound events) is generally **not** the instance the gateway
+dialed its outbound WS into. The producing instance therefore publishes the
+event on the connector's internal **relay bus** (Redis pub/sub; `RelayBus` in
+`src/core/relayBus.ts`) keyed by tenant. Every connector instance subscribes and
+routes each message to its **local** sessions for that tenant
+(`RelayServer.routeBusMessage`); the single instance that actually holds the
+gateway's socket delivers it, and instances with no local session for the tenant
+no-op. Cross-instance delivery is thus an in-cluster Redis hop, not a public
+HTTP call.

+Frames (connector → gateway, over the WS):
+
+- `{"type":"inbound", "event": <MessageEvent>, "bufferId"?}`

+**Trust.** The WS upgrade is authenticated with the gateway's per-gateway secret
+(§6.1), so the channel is trusted end to end — inbound frames are not separately
+HMAC-signed (the authenticated socket subsumes the per-delivery origin proof the
+old HTTP path needed). The relay-bus hop is inside the connector trust domain
+(same as the lease/buffer/capability stores).

-"""Gateway-side inbound delivery receiver. EXPERIMENTAL.
-
-The connector delivers normalized inbound events to a tenant's gateway over a
-**signed HTTP POST** (connector ``src/relay/httpGatewayDelivery.ts``), NOT over
-the gateway's outbound ``/relay`` WebSocket: the connector instance that owns a
-platform socket is generally not the instance a given gateway dialed out to, so
-inbound is delivered to a tenant ENDPOINT (which may load-balance across gateway
-instances). Each delivery is HMAC-signed with the per-tenant **delivery key**
-(``gateway/relay/auth.py``); this receiver verifies the signature over the EXACT
-raw request bytes before accepting the event.
-
-Two routes (mirroring the connector's two POST targets):
-  POST {base}            {"type":"message",  "event": <MessageEvent>, ...}
-  POST {base}/interrupt  {"type":"interrupt","session_key": ..., "reason"?}
-
-The receiver:
-  1. reads the RAW body bytes (never a reparsed/re-serialized form — the HMAC is
-     over the literal bytes the connector signed),
-  2. verifies ``x-relay-signature`` / ``x-relay-timestamp`` against the delivery
-     key verify list (primary + secondary during rotation), within the replay
-     window — rejects 401 on any failure,
-  3. parses the JSON and dispatches: a ``message`` to the inbound handler (the
-     RelayAdapter's ``handle_message`` via the transport's normal path), an
-     ``interrupt`` to the interrupt handler.
-
-EXPERIMENTAL: the transport protocol may change without a deprecation cycle
-until ≥2 Class-1 platforms validate it. See docs/relay-connector-contract.md.

+"""Nous Portal terminal-billing HTTP client (Phase 2b).
+
+Thin, fail-loud client for the four ``/api/billing/*`` endpoints the terminal
+billing screens drive. Companion to ``hermes_cli/nous_account.py`` (which owns
+read-only entitlement/balance) — this module owns the *write* side: buy credits,
+poll a charge, configure auto-reload.
+
+Design rules:
+
+- **Money is decimal, never float.** The server emits decimal STRINGS
+  (``"142.5"`` — not fixed 2dp). We parse with :class:`decimal.Decimal` and never
+  round-trip through float.
+- **This client raises typed exceptions; it does NOT fail open.** Fail-open is the
+  *caller's* job (the ``agent/billing_view.py`` builders) so each surface can
+  decide how to degrade. A raw network/HTTP error here surfaces as
+  :class:`BillingError` (or a subclass) carrying the parsed server ``error`` code,
+  HTTP status, ``portalUrl`` deep-link, and ``retry_after``.
+- **Auth** = the OAuth bearer JWT Hermes already holds for inference
+  (``get_provider_auth_state("nous")["access_token"]``). No API-key auth on these.
+- **Portal base URL** resolves with the same precedence as the device-flow login
+  (``auth.py``): ``HERMES_PORTAL_BASE_URL`` → ``NOUS_PORTAL_BASE_URL`` → the
+  stored auth-state ``portal_base_url`` → the registry default. This is how the
+  E2E run points the client at a preview deployment with zero code change.

+description: Drive the Unreal Engine 5.8 editor over its local MCP server.
+source: https://dev.epicgames.com/documentation/unreal-engine/unreal-mcp-in-unreal-editor
+
+# Epic's official "Unreal MCP" plugin (internal id ModelContextProtocol)
+# embeds an MCP server inside the running Unreal Editor process and serves it
+# over local HTTP. There is nothing to install on the Hermes side — the user
+# enables the plugin in-editor and the server binds to 127.0.0.1. Hermes's
+# MCP client just connects to the URL.
+#
+# Default bind is http://127.0.0.1:8000/mcp (port + path are configurable in
+# Editor Preferences > General > Model Context Protocol). If you change the
+# port/path in-editor, edit the url in mcp_servers.unreal-engine afterward.
+transport:
+  type: http
+  url: http://127.0.0.1:8000/mcp
+
+# The editor-embedded server accepts connections only from the same machine
+# and has no authentication of its own (Epic's experimental design — not for
+# remote use). Nothing to prompt for.
+auth:
+  type: none
+
+# Tool selection at install time:
+# The plugin advertises engine tools (spawn actors, configure lighting, create
+# material instances, inspect Slate widgets, run automation tests) and is
+# user-extensible, so the exact surface depends on the project's enabled
+# toolsets. Leave default_enabled unset — the install-time probe lists whatever
+# the live editor exposes and pre-checks all of it; users prune from there.
+
+post_install: |
+  This entry connects to Epic's official Unreal MCP plugin, which runs INSIDE
+  the Unreal Editor. Before Hermes can connect:
+
+    1. Open your project in Unreal Editor 5.8+.
+    2. Edit > Plugins, search "Unreal MCP", enable it, restart the editor
+       (the Toolset Registry dependency enables automatically).
+    3. Edit > Editor Preferences > General > Model Context Protocol, turn on
+       "Auto Start Server" (or run `ModelContextProtocol.StartServer` in the
+       editor console). It binds to http://127.0.0.1:8000/mcp by default.
+
+  Start Hermes AFTER the editor's server is running so the tools are probed.
+  If you changed the port or URL path in Editor Preferences, update the url in
+  mcp_servers.unreal-engine to match.
+
+  Status: Epic ships this as EXPERIMENTAL. The server runs Tool calls serially
+  on the engine game thread — avoid issuing overlapping calls.
+
+  Re-run the tool checklist any time with:
+    hermes mcp configure unreal-engine

+and only when its System32 directory is on ``PATH``.  Under PowerShell 7+
+(``pwsh``) -- or any session where ``powershell`` isn't on ``PATH`` -- the
+spawn dies and uv installation aborts.
+
+The fix resolves the PowerShell host executable (preferring the absolute path
+of the running host, then ``powershell``/``pwsh`` via ``Get-Command``) and
+invokes *that* instead of a bare name.  These tests lock that contract at the
+source level (the script only runs on Windows, so there's no runner to
+execute it on Linux CI).

 ```
 
+## Customizing platform hints
+
+The platform hint (Layer 10 above) is the per-surface guidance Hermes
+injects for Telegram, WhatsApp, Slack, CLI, and other platforms — for
+example "you are on a terminal, avoid Markdown." The built-in defaults
+live in `PLATFORM_HINTS` (`agent/system_prompt.py`); plugin-provided
+platforms supply theirs through the platform registry.
+
+An administrator can append to or replace a single platform's hint from
+`config.yaml` via the top-level `platform_hints` key, without touching
+any other platform:
+
+```yaml
+platform_hints:
+  whatsapp:
+    append: >
+      When tabular output would be useful, invoke the table_formatting
+      skill instead of emitting a Markdown table.
+  slack:
+    replace: "You are on Slack. Keep responses tight and avoid wide tables."
+  telegram: "Prefer short messages; split long answers."   # shorthand = append
+```
+
+- `append` — keep the built-in hint and add the extra text after it.
+- `replace` — substitute the built-in hint entirely.
+- A bare string — shorthand for `append`.
+- `replace` wins over `append` when both are present.
+- A malformed entry is ignored defensively and falls back to the
+  unmodified default, so a bad config value can never break prompt
+  assembly or leak across platforms.
+
+The override is resolved when the system prompt is built (session start,
+and again on compaction since that rebuilds the prompt). It produces a
+byte-stable hint for a fixed config, so it lives in the **stable** tier
+alongside the built-in hint and does not break prompt caching — it is
+not a live mid-session mutation of a frozen prompt.

 ## How SOUL.md appears in the prompt
 
 `SOUL.md` lives at `~/.hermes/SOUL.md` and serves as the agent's identity — the very first section of the system prompt. The loading logic in `prompt_builder.py` works as follows:

+Take this photo and make it a rainy Tokyo street at night → <image>

+
+Two inputs drive the edit:
+
+- **`image_url`** — the primary source image to edit/transform (public URL or local path).
+- **`reference_image_urls`** — additional style/composition references (capped per-model).
+
+### Which backends support editing
+
+| Backend | Image-to-image | Reference cap | How |
+|---|---|---|---|
+| **FAL.ai** (edit-capable models below) | ✓ | up to 9 | routes to the model's `/edit` endpoint |
+| **OpenAI** (`gpt-image-2`) | ✓ | up to 16 | `images.edit()` |
+| **xAI** (Grok Imagine) | ✓ | 1 | `/v1/images/edits` (`grok-imagine-image-quality`) |
+| **Krea** (`Krea 2`) | ✓ | up to 10 | reference-guided generation (`image_style_references`) |
+| **OpenAI (Codex auth)** | ✗ | — | text-to-image only |

+`nano-banana-pro`, `gpt-image-1.5`, `gpt-image-2`, `ideogram/v3`, and

+`krea/*`) reject image inputs with a clear error pointing you at an
+edit-capable model.
