It accepts OpenAI Chat Completions, Anthropic Messages, and OpenAI Responses requests, injects the broker-resolved access token, and forwards the bytes to the real provider. Clients (containerised gjc, llm-git, the macOS usage widget, …) never see the access token.\n\nTransport security between operator, broker, and gateway is delegated to the operator (Tailscale / Wireguard / reverse proxy + TLS). Every endpoint except `/v1/healthz` (broker) and `/healthz` (gateway) requires a bearer token.\n\nSource: `packages/ai/src/auth-broker/`, `packages/ai/src/auth-gateway/`, `packages/coding-agent/src/cli/auth-broker-cli.ts`, `packages/coding-agent/src/cli/auth-gateway-cli.ts`, `packages/coding-agent/src/session/auth-broker-config.ts`.\n\n## Data flow\n\n```\n ┌────────────────────────────────────────────────────────────┐\n │ broker host │\n │ │\n developer ──▶ │ ┌──────────────────────────┐ ┌────────────────────┐ │\n laptop / │ │ gjc auth-broker serve │◀──▶│ SQLite agent.db │ │\n CI │ │ - holds refresh tokens │ │ (canonical writer)│ │\n │ │ - background refresher │ └────────────────────┘ │\n │ │ /v1/{snapshot,refresh,…}│ │\n │ └─────────┬────────────────┘ │\n │ │ bearer ($CONFIG_DIR/auth-broker.token) │\n │ ▼ │\n │ ┌──────────────────────────┐ │\n │ │ gjc auth-gateway serve │ RemoteAuthCredentialStore │\n │ │ /v1/{chat,messages,…} │ pulls /v1/snapshot at boot, │\n │ │ /v1/usage, /v1/models │ refreshes credentials by id │\n │ └─────────┬────────────────┘ via the broker on expiry │\n └────────────┼───────────────────────────────────────────────┘\n │ bearer ($CONFIG_DIR/auth-gateway.token)\n ▼\n unauthenticated clients\n (llm-git, macOS widget, IDE plugins, …)\n │\n ▼ same path is forwarded with Authorization\n api.anthropic.com / api.openai.com / …\n```\n\nThe broker is the only writer of OAuth refresh tokens. Clients (including the gateway itself) load a redacted snapshot in which every `refresh` field has been replaced with `REMOTE_REFRESH_SENTINEL`; when an access token expires the client calls `POST /v1/credential/:id/refresh` and the broker performs the refresh server-side. `RemoteAuthCredentialStore` rejects any local code path that tries to write through it, with an error pointing at `gjc auth-broker login` / `gjc auth-broker logout`.\n\n## auth-broker\n\n### CLI\n\n```\ngjc auth-broker serve [--bind=host:port] # boot the broker\ngjc auth-broker token [--regenerate] [--json] # print or rotate the bearer token\ngjc auth-broker login [--via=user@host] [--dry-run]\ngjc auth-broker logout \ngjc auth-broker import [--provider=] [--include-disabled] [--dry-run] [--json]\ngjc auth-broker migrate --from-local [--dry-run] [--json]\ngjc auth-broker status [--json]\n```\n\n- `serve` opens the local SQLite store at `getAgentDbPath()` and binds an HTTP listener (default `127.0.0.1:8765`). On startup a token is ensured at `/auth-broker.token` (mode `0600`, `0700` parent dir). The background refresher refreshes any OAuth credential whose `expires - Date.now() < refreshSkewMs` (default 5 min) every `refreshIntervalMs` (default 60 s).\n- `token` prints the cached bearer or generates a new one. `--regenerate` rotates it.\n- `login ` runs the per-provider OAuth flow locally, or — with `--via=user@host` — `ssh -L :127.0.0.1: user@host gjc auth-broker login ` so the OAuth callback hits the local browser but the credential is written on the broker host. Built-in callback ports: `anthropic:54545`, `openai-code:1455`, `google-gemini-cli:8085`, `google-antigravity:51121`, `gitlab-duo:8080`.\n- `logout ` deletes every credential row for ``.\n- `import ` imports CLIProxyAPI-style JSON credentials into the local SQLite store. Maps `type` field → gjc provider (`anthropic-model → anthropic`, `openai-code → openai-code`, `gemini → google-gemini-cli`, `antigravity → google-antigravity`, `gemini-cli → google-gemini-cli`).\n- `migrate --from-local` walks the local SQLite store + env-derived credentials and idempotently uploads them to the configured broker (`POST /v1/credential`).\n- `status` health-pings the configured remote broker.\n\n### Endpoints\n\n| Method | Path | Auth | Purpose |\n| ------ | ---- | ---- | ------- |\n| `GET` | `/v1/healthz` | none | Liveness + version |\n| `GET` | `/v1/snapshot` | bearer | Redacted snapshot (refresh tokens replaced by sentinel) |\n| `POST` | `/v1/credential` | bearer | Upsert one OAuth or API-key credential |\n| `POST` | `/v1/credential/:id/refresh` | bearer | Force-refresh one OAuth credential |\n| `POST` | `/v1/credential/:id/disable` | bearer | Disable one credential with a recorded cause |\n| `GET` | `/v1/usage` | bearer | Aggregate `UsageReport[]` across credentials |\n\nRequests use `Authorization: Bearer `. The server compares against an in-memory token allow-list; the gateway’s implementation uses a timing-safe comparison.\n\n### Background refresher\n\n`AuthBrokerRefresher` iterates active OAuth credentials at `refreshIntervalMs` cadence and refreshes any within `refreshSkewMs` of expiry. Refreshes are single-flighted per credential id so a slow refresh cannot be retriggered. The refresher distinguishes:\n\n- **definitive failures** (`invalid_grant`, `invalid_token`, `revoked`, unauthorized refresh-token, 401/403 not from a network blip) — credentials are passed to `AuthStorage.disableCredentialById(id, cause)` so the next snapshot pull surfaces a clean delete on the client;\n- **transient failures** (timeout / ECONNREFUSED / fetch failed) — left in place for the next sweep.\n\n## auth-gateway\n\n### CLI\n\n```\ngjc auth-gateway serve [--bind=host:port] [--no-auth]\ngjc auth-gateway token [--regenerate] [--json]\ngjc auth-gateway status [--json]\n```\n\n- `serve` requires `GJC_AUTH_BROKER_URL` (or `auth.broker.url` in `config.yml`) — the gateway is itself a broker client. It calls `AuthBrokerClient.fetchSnapshot()`, wraps it in `RemoteAuthCredentialStore`, and constructs an `AuthStorage` that resolves access tokens through the broker. Default bind is `127.0.0.1:4000`. The gateway token is stored at `/auth-gateway.token` (`0600`); `--no-auth` disables the bearer check entirely (loopback-only use).\n- `token` / `status` mirror the broker’s equivalents.\n\n### Endpoints\n\n| Method | Path | Auth | Purpose |\n| ------ | ---- | ---- | ------- |\n| `GET` | `/healthz` | none | Liveness + version |\n| `GET` | `/v1/usage` | bearer | Aggregate `UsageReport[]` (proxied through `AuthStorage`) |\n| `GET` | `/v1/models` | bearer | Bundled-model catalog filtered to providers with credentials |\n| `POST` | `/v1/chat/completions` | bearer | OpenAI Chat Completions wire format |\n| `POST` | `/v1/messages` | bearer | Anthropic Messages wire format |\n| `POST` | `/v1/responses` | bearer | OpenAI Responses wire format |\n\nThe model id is read from the top-level `model` field. The gateway picks the first bundled `Model` matching that id and:\n\n- **Passthrough fast-path** — when the inbound wire format matches the model’s native API (`openai-chat → openai-completions`, `anthropic-messages → anthropic-messages`, `openai-responses → openai-responses`), the request body is forwarded byte-for-byte with the client `Authorization`/`x-api-key` stripped and replaced by `Authorization: Bearer `. Provider-specific fields (`cache_control`, `service_tier`, tool-choice extensions, …) flow through unmodified. Hop-by-hop headers (RFC 7230) plus `Content-Encoding`/`Content-Length` are stripped from the upstream response.\n- **Translate path** — when the inbound format and the resolved model’s API differ (e.g. `/v1/chat/completions` targeting an Anthropic model, or `/v1/responses` targeting `openai-code-responses` which runs over a websocket transport), the request is parsed against the wire schema, rebuilt into an gjc `Context`, dispatched through `streamSimple()`, and re-encoded back to the inbound format (SSE for streamed responses).\n\n`idleTimeout` on the underlying `Bun.serve` is set to `255 s` so long thinking-budget calls do not get killed by Bun’s default idle timeout.\n\n## Usage cache: server-side 5-min jitter + client-side 15 s single-flight\n\nTwo layers cache the aggregate provider-usage report. Both are intentional and stacked.\n\n### Server-side cache (broker `AuthStorage`)\n\n`AuthStorage` caches each credential’s `UsageReport` in the broker’s SQLite store at a **5-minute per-credential TTL with ±25 % jitter**. Anthropic and OpenAI rate-limit `/usage` aggressively per source IP, and a synchronized 5-credential fan-out trips 429s every cycle; the jitter decorrelates refresh times within a few cycles. On fetch failure the store keeps the **last-good** report for up to 24 h with a short jittered re-poll window — so a transient upstream blip never blanks out the widget.\n\nConstants: `USAGE_REPORT_TTL_MS = 5 * 60_000`, `USAGE_LAST_GOOD_RETENTION_MS = 24 * 60 * 60_000` (`packages/ai/src/auth-storage.ts`).\n\n### Client-side single-flight (`RemoteAuthCredentialStore`)\n\nWhen the gateway (or any other broker client) calls `fetchUsageReports()` / `getUsageReport(provider, credential)`, `RemoteAuthCredentialStore` coalesces concurrent calls into a single `GET /v1/usage` round-trip and caches the result for **15 s** in memory.\n\n- `USAGE_CACHE_TTL_MS = 15_000` (`packages/ai/src/auth-broker/remote-store.ts`).\n- A single `#usageInflight` promise is shared across all callers; a per-caller `AbortSignal` is **raced** against the shared promise, not threaded into it, so one caller’s abort never cascades into a peer’s in-flight request.\n- On fetch failure the rejected promise is logged and the awaited value is `null` — callers (`AuthStorage.fetchUsageReports`, `#getUsageReport`) treat a `null` report as \"no usage signal for this cycle\" and proceed without it. **This is the 15 s TTL fallback**: the client absorbs transient broker outages by suppressing the error, returning `null` to ranking, and re-attempting after the 15 s window.\n\nThe 15 s client window deliberately sits below the broker’s 5 min server cache, so almost every client poll is served from the broker’s already-cached value; the client cache exists to absorb the parallel fan-out generated by `AuthStorage.#rankOAuthSelections` into a single broker round-trip.\n\n## Operator opt-in\n\nThe broker is **off** unless `GJC_AUTH_BROKER_URL` (or `auth.broker.url` in `config.yml`) is set. When set, `discoverAuthStorage` in `packages/coding-agent/src/sdk/session.ts` swaps the local SQLite credential store for `RemoteAuthCredentialStore` and every API call resolves credentials through the broker.\n\n### Environment variables\n\n| Variable | Purpose | Required when |\n| -------- | ------- | ------------- |\n| `GJC_AUTH_BROKER_URL` | Base URL of the remote auth-broker (e.g. `https://broker.tailnet:8765`). Selecting this puts the client in broker mode — local SQLite is bypassed. | Any time the gjc client should resolve credentials through a broker (and required by `gjc auth-gateway serve`). |\n| `GJC_AUTH_BROKER_TOKEN` | Bearer token used for every broker endpoint except `/v1/healthz`. | When `GJC_AUTH_BROKER_URL` is set and no token is available from `auth.broker.token` or `/auth-broker.token`. |\n\nResolution order in `resolveAuthBrokerConfig()`:\n\n1. `GJC_AUTH_BROKER_URL` env (else `auth.broker.url` from `config.yml`, with `$ENV_NAME` resolution);\n2. `GJC_AUTH_BROKER_TOKEN` env (else `auth.broker.token` from `config.yml`, else `/auth-broker.token`);\n3. URL set but no token resolvable → hard error pointing at the token file path.\n\nThe gateway has no dedicated env vars — it inherits `GJC_AUTH_BROKER_*` because it is itself a broker client.\n\n### `config.yml` keys\n\n| Key | Default | Purpose |\n| --- | ------- | ------- |\n| `auth.broker.url` | unset | Same as `GJC_AUTH_BROKER_URL`; env wins. Hidden from the settings UI. |\n| `auth.broker.token` | unset | Same as `GJC_AUTH_BROKER_TOKEN`; env wins. Values may be the literal token or `$ENV_NAME` to indirect through env. |\n\n### Token files\n\n| Path | Owner | Mode |\n| ---- | ----- | ---- |\n| `/auth-broker.token` | `gjc auth-broker serve` (created at first start) | `0600` in a `0700` parent dir |\n| `/auth-gateway.token` | `gjc auth-gateway serve` (skipped under `--no-auth`) | `0600` in a `0700` parent dir |\n\n`` resolves to `~/.gjc/` (respecting `GJC_CONFIG_DIR`).\n\n## Interaction with the local API-key resolution order\n\nThe broker only owns OAuth credentials and provider-API-key credentials that were uploaded to it. The standard credential ladder in `models.md` (`Auth and API key resolution order`) is preserved, with one addition committed alongside the gateway:\n\n- `AuthStorage.setConfigApiKey / removeConfigApiKey / clearConfigApiKeys` let a `models.yml` `apiKey` beat a stored OAuth token **without** overriding an explicit `--api-key`. This is what allows a broker-resolved OAuth credential to be reliably shadowed by a per-environment `models.yml` config key when both are present.\n\n## See also\n\n- [`secrets.md`](./secrets.md) — secret obfuscation around tokens that *do* leak through (e.g. `GJC_AUTH_BROKER_TOKEN` in shell output).\n- [`models.md`](./models.md) — provider auth resolution order; the broker plugs in at layers 2–3 (stored credentials).\n- [`environment-variables.md`](./environment-variables.md) — full env reference including `GJC_AUTH_BROKER_URL` / `GJC_AUTH_BROKER_TOKEN`.\n", "bash-tool-runtime.md": "# Bash tool runtime\n\nThis document describes the **`bash` tool** runtime path used by agent tool calls, from command normalization to execution, truncation/artifacts, and rendering.\n\nIt also calls out where behavior diverges in interactive TUI, print mode, ACP, and user-initiated bang (`!`) shell execution.\n\n## Scope and runtime surfaces\n\nThere are two different bash execution surfaces in coding-agent:\n\n1. **Tool-call surface** (`toolName: \"bash\"`): used when the model calls the bash tool.\n - Entry point: `BashTool.execute()`.\n - Parameters include `command`, optional `env`, `timeout`, `cwd`, `head`, `tail`, `pty`, and, when `async.enabled` is true, `async`.\n2. **User bang-command surface** (`!cmd` from interactive input): session-level helper path.\n - Entry point: `AgentSession.executeBash()`.\n\nBoth eventually use `executeBash()` in `src/exec/bash-executor.ts` for non-PTY execution, but only the tool-call path runs normalization/interception, optional managed background-job handling, and tool renderer logic.\n\n## End-to-end tool-call pipeline\n\n## 1) Input handling and parameter merge\n\n`BashTool.execute()` currently handles input before execution as follows:\n\n- validates optional `env` names against shell-variable syntax,\n- extracts a leading `cd && ...` into `cwd` when `cwd` was not supplied,\n- rejects `async: true` when `async.enabled` is false,\n- uses only explicit `head`/`tail` tool args for post-run filtering.\n\n`normalizeBashCommand()` still exists in `src/tools/bash-normalize.ts`, but `BashTool.execute()` does not call it in the current source. Trailing shell pipes such as `| head -n 50` remain part of the shell command unless the caller uses the structured `head`/`tail` args.\n\n## 2) Optional interception (blocked-command path)\n\nIf `bashInterceptor.enabled` is true, `BashTool` loads rules from settings and runs `checkBashInterception()` against the normalized command.\n\nInterception behavior:\n\n- command is blocked **only** when:\n - regex rule matches, and\n - the suggested tool is present in `ctx.toolNames`.\n- invalid regex rules are silently skipped.\n- on block, `BashTool` throws `ToolError` with message:\n - `Blocked: ...`\n - original command included.\n\nDefault rule patterns (defined in code) target common misuses:\n\n- file readers (`cat`, `head`, `tail`, ...)\n- search tools (`grep`, `rg`, ...)\n- file finders (`find`, `fd`, ...)\n- in-place editors (`sed -i`, `perl -i`, `awk -i inplace`)\n- shell redirection writes (`echo ... > file`, heredoc redirection)\n\n### Caveat\n\n`InterceptionResult` includes `suggestedTool`, but `BashTool` currently surfaces only the message text (no structured suggested-tool field in `details`).\n\n## 3) CWD validation and timeout clamping\n\n`cwd` is resolved relative to session cwd (`resolveToCwd`), then validated via `stat`:\n\n- missing path -> `ToolError(\"Working directory does not exist: ...\")`\n- non-directory -> `ToolError(\"Working directory is not a directory: ...\")`\n\nTimeout is clamped to `[1, 3600]` seconds and converted to milliseconds.\n\n## 4) Artifact allocation\n\nBefore execution, the tool allocates an artifact path/id (best-effort) for truncated output storage.\n\n- artifact allocation failure is non-fatal (execution continues without artifact spill file),\n- artifact id/path are passed into execution path for full-output persistence on truncation.\n\n## 5) PTY vs non-PTY execution selection\n\n`BashTool` chooses PTY execution only when all are true:\n\n- tool input `pty === true`\n- `GJC_NO_PTY !== \"1\"`\n- tool context has UI (`ctx.hasUI === true` and `ctx.ui` set)\n\nOtherwise it uses non-interactive `executeBash()`.\n\nThat means print mode and non-UI tool contexts always use non-PTY.\n\n## Non-interactive execution engine (`executeBash`)\n\n## Shell session reuse model\n\n`executeBash()` caches native `Shell` instances in a process-global map keyed by:\n\n- shell path,\n- configured command prefix,\n- snapshot path,\n- serialized shell env,\n- optional agent session key.\n\nSession-level bang-command executions pass `sessionKey: this.sessionId`.\n\nTool-call executions pass `sessionKey: this.session.getSessionId?.()`, when available. In both surfaces, a session key isolates shell reuse per session; without one, reuse falls back to shell config/snapshot/env.\n\n## Shell config and snapshot behavior\n\nAt each call, executor loads settings shell config (`shell`, `env`, optional `prefix`).\n\nIf selected shell includes `bash`, it attempts `getOrCreateSnapshot()`:\n\n- snapshot captures aliases/functions/options from user rc,\n- snapshot creation is best-effort,\n- failure falls back to no snapshot.\n\nIf `prefix` is configured, command becomes:\n\n```text\n \n```\n\n## Streaming and cancellation\n\n`Shell.run()` streams chunks to `OutputSink` and optional `onChunk` callback.\n\nCancellation:\n\n- aborted signal triggers `shellSession.abort(...)`,\n- timeout from native result is mapped to `cancelled: true` + annotation text,\n- explicit cancellation similarly returns `cancelled: true` + annotation.\n\nNo exception is thrown inside executor for timeout/cancel; it returns structured `BashResult` and lets caller map error semantics.\n\n## Interactive PTY path (`runInteractiveBashPty`)\n\nWhen PTY is enabled, tool runs `runInteractiveBashPty()` which opens an overlay console component and drives a native `PtySession`.\n\nBehavior highlights:\n\n- xterm-headless virtual terminal renders viewport in overlay,\n- keyboard input is normalized (including Kitty sequences and application cursor mode handling),\n- `esc` while running kills the PTY session,\n- terminal resize propagates to PTY (`session.resize(cols, rows)`).\n\nEnvironment hardening defaults are injected for unattended runs:\n\n- pagers disabled (`PAGER=cat`, `GIT_PAGER=cat`, etc.),\n- editor prompts disabled (`GIT_EDITOR=true`, `EDITOR=true`, ...),\n- terminal/auth prompts reduced (`GIT_TERMINAL_PROMPT=0`, `SSH_ASKPASS=/usr/bin/false`, `CI=1`),\n- package-manager/tool automation flags for non-interactive behavior.\n\nPTY output is normalized (`CRLF`/`CR` to `LF`, `sanitizeText`) and written into `OutputSink`, including artifact spill support.\n\nOn PTY startup/runtime error, sink receives `PTY error: ...` line and command finalizes with undefined exit code.\n\n## Output handling: streaming, truncation, artifact spill\n\nBoth PTY and non-PTY paths use `OutputSink`.\n\n## OutputSink semantics\n\n- keeps an in-memory UTF-8-safe tail buffer (`DEFAULT_MAX_BYTES`, currently 50KB),\n- tracks total bytes/lines seen,\n- if artifact path exists and output overflows (or file already active), writes full stream to artifact file,\n- when memory threshold overflows, trims in-memory buffer to tail (UTF-8 boundary safe),\n- marks `truncated` when overflow/file spill occurs.\n\n`dump()` returns:\n\n- `output` (possibly annotated prefix),\n- `truncated`,\n- `totalLines/totalBytes`,\n- `outputLines/outputBytes`,\n- `artifactId` if artifact file was active.\n\n### Long-output caveat\n\nRuntime truncation is byte-threshold based in `OutputSink` (50KB default). It does not enforce a hard 2000-line cap in this code path.\n\n## Live tool updates and async jobs\n\nFor non-PTY foreground execution, `BashTool` uses a separate `TailBuffer` for partial updates and emits `onUpdate` snapshots while command is running.\n\nFor PTY execution, live rendering is handled by custom UI overlay, not by `onUpdate` text chunks.\n\nWhen `async.enabled` is true and the call passes `async: true`, `BashTool` starts a managed bash job, returns a running job result with a job id, and stores completion through the session managed-job path. Auto-backgrounding can also start this path after `bash.autoBackground.thresholdMs`.\n\n## Result shaping, metadata, and error mapping\n\nAfter execution:\n\n1. `cancelled` handling:\n - if abort signal is aborted -> throw `ToolAbortError` (abort semantics),\n - else -> throw `ToolError` (treated as tool failure).\n2. PTY `timedOut` -> throw `ToolError`.\n3. apply head/tail filters to final output text (`applyHeadTail`, head then tail).\n4. empty output becomes `(no output)`.\n5. attach truncation metadata via `toolResult(...).truncationFromSummary(result, { direction: \"tail\" })`.\n6. exit-code mapping:\n - missing exit code -> `ToolError(\"... missing exit status\")`\n - non-zero exit -> `ToolError(\"... Command exited with code N\")`\n - zero exit -> success result.\n\nSuccess payload structure:\n\n- `content`: text output,\n- `details.meta.truncation` when truncated, including:\n - `direction`, `truncatedBy`, total/output line+byte counts,\n - `shownRange`,\n - `artifactId` when available.\n\nBecause built-in tools are wrapped with `wrapToolWithMetaNotice()`, truncation notice text is appended to final text content automatically (for example: `Full: artifact://`).\n\n## Rendering paths\n\n## Tool-call renderer (`bashToolRenderer`)\n\n`bashToolRenderer` is used for tool-call messages (`toolCall` / `toolResult`):\n\n- collapsed mode shows visual-line-truncated preview,\n- expanded mode shows all currently available output text,\n- warning line includes truncation reason and `artifact://` when truncated,\n- timeout value (from args) is shown in footer metadata line.\n\n### Caveat: full artifact expansion\n\n`BashRenderContext` has `isFullOutput`, but current renderer context builder does not set it for bash tool results. Expanded view still uses the text already in result content (tail/truncated output) unless another caller provides full artifact content.\n\n## User bang-command component (`BashExecutionComponent`)\n\n`BashExecutionComponent` is for user `!` commands in interactive mode (not model tool calls):\n\n- streams chunks live,\n- collapsed preview keeps last 20 logical lines,\n- line clamp at 4000 chars per line,\n- shows truncation + artifact warnings when metadata is present,\n- marks cancelled/error/exit state separately.\n\nThis component is wired by `CommandController.handleBashCommand()` and fed from `AgentSession.executeBash()`.\n\n## Mode-specific behavior differences\n\n| Surface | Entry path | PTY eligible | Live output UX | Error surfacing |\n| ------------------------------ | ----------------------------------------------------- | -------------------------------------------------------------------- | ------------------------------------------------------------------------ | ------------------------------------------------ |\n| Interactive tool call | `BashTool.execute` | Yes, when `pty=true` and UI exists and `GJC_NO_PTY!=1` | PTY overlay (interactive) or streamed tail updates | Tool errors become `toolResult.isError` |\n| Print mode tool call | `BashTool.execute` | No (no UI context) | No TUI overlay; output appears in event stream/final assistant text flow | Same tool error mapping |\n| ACP tool call (agent tooling) | `BashTool.execute` | Usually no UI -> non-PTY | Structured protocol events/results | Same tool error mapping |\n| Interactive bang command (`!`) | `AgentSession.executeBash` + `BashExecutionComponent` | No (uses executor directly) | Dedicated bash execution component | Controller catches exceptions and shows UI error |\n\n## Operational caveats\n\n- Interceptor only blocks commands when suggested tool is currently available in context.\n- If artifact allocation fails, truncation still occurs but no `artifact://` back-reference is available.\n- Shell session cache has no explicit eviction in this module; lifetime is process-scoped.\n- PTY and non-PTY timeout surfaces differ:\n - PTY exposes explicit `timedOut` result field,\n - non-PTY maps timeout into `cancelled + annotation` summary.\n\n## Implementation files\n\n- [`src/tools/bash.ts`](../packages/coding-agent/src/tools/bash.ts) — tool entrypoint, input handling/interception, async and PTY/non-PTY selection, result/error mapping, bash tool renderer.\n- [`src/tools/bash-normalize.ts`](../packages/coding-agent/src/tools/bash-normalize.ts) — post-run head/tail filtering;

It scans existing `.md` files on initialization to continue from the next index on resume.\n\n## Persistence dataflow\n\n## 1) Session entry persistence rewrite path\n\nBefore session entries are written (`#rewriteFile` / incremental persist), `SessionManager` calls `prepareEntryForPersistence()` (via `truncateForPersistence`).\n\nKey behaviors:\n\n1. **Large string truncation**: oversized strings are cut and suffixed with `\"[Session persistence truncated large content]\"`; signature fields (`thinkingSignature`, `thoughtSignature`, `textSignature`) are cleared instead of truncated.\n2. **Transient field stripping**: `partialJson` and `jsonlEvents` are removed from persisted entries.\n3. **Image externalization to blobs**:\n - image blocks in `content` arrays are externalized when `data` is not already a blob ref and base64 length is at least threshold (`BLOB_EXTERNALIZE_THRESHOLD = 1024`),\n - provider-style `image_url` data URLs are externalized when they start with `data:image/` and contain `;base64,`,\n - image block `data` is stored as decoded binary bytes,\n - provider data URLs are stored as the original UTF-8 data URL string,\n - persisted values are replaced with `blob:sha256:`.\n\nThis keeps session JSONL compact while preserving recoverability.\n\n## 2) Session load rehydration path\n\nWhen opening a session (`setSessionFile`), after migrations, `SessionManager` runs `resolveBlobRefsInEntries()`.\n\nFor message/custom-message image blocks with `blob:sha256:` and for persisted provider `image_url` fields with blob refs:\n\n- reads blob bytes from blob store,\n- converts image-block bytes back to base64,\n- converts provider `image_url` blobs back to the original string,\n- mutates in-memory entry fields for runtime consumers.\n\nIf blob is missing:\n\n- `resolveImageData()` logs warning,\n- returns original ref string unchanged,\n- load continues (no hard crash).\n\n## 3) Tool output spill/truncation path\n\n`OutputSink` powers streaming output in bash/python/ssh and related executors.\n\nBehavior:\n\n1. Every chunk is sanitized and appended to in-memory tail buffer.\n2. When in-memory bytes exceed spill threshold (`DEFAULT_MAX_BYTES`, 50KB), sink marks output truncated.\n3. If an artifact path is available, sink opens a file writer and writes:\n - existing buffered content once,\n - all subsequent chunks.\n4. In-memory buffer is always trimmed to tail window for display.\n5. `dump()` returns summary including `artifactId` only when file sink was successfully created.\n\nPractical effect:\n\n- UI/tool return shows truncated tail,\n- full output is preserved in artifact file and referenced as `artifact://`.\n\nIf file sink creation fails (I/O error, missing path, etc.), sink silently falls back to in-memory truncation only; full output is not persisted.\n\n## URL access model\n\n## `blob:` references\n\n`blob:sha256:` is a persistence reference inside session entry payloads, not an internal URL scheme handled by the router. Resolution is done by `SessionManager` during session load.\n\n## `artifact://`\n\nHandled by `ArtifactProtocolHandler`:\n\n- requires active session artifact directory,\n- ID must be numeric,\n- resolves by matching filename prefix `.`,\n- returns raw text (`text/plain`) from the matched `.log` file,\n- when missing, error includes list of available artifact IDs.\n\nMissing directory behavior:\n\n- if artifacts directory does not exist, throws `No artifacts directory found`.\n\n## `agent://`\n\nHandled by `AgentProtocolHandler` over `/.md`:\n\n- plain form returns markdown text,\n- `/path` or `?q=` forms perform JSON extraction,\n- path and query extraction cannot be combined,\n- if extraction requested, file content must parse as JSON.\n\nMissing directory behavior:\n\n- throws `No artifacts directory found`.\n\nMissing output behavior:\n\n- throws `Not found: ` with available IDs from existing `.md` files.\n\nRead tool integration:\n\n- `read` supports offset/limit pagination for non-extraction internal URL reads,\n- rejects `offset/limit` when `agent://` extraction is used.\n\n## Resume, fork, and move semantics\n\n## Resume\n\n- `ArtifactManager` scans existing `{id}.*.log` files on first allocation and continues numbering.\n- `AgentOutputManager` scans existing `.md` output IDs and continues numbering.\n- `SessionManager` rehydrates blob refs to base64 on load.\n\n## Fork\n\n`SessionManager.fork()` creates a new session file with new session ID and `parentSession` link, then returns old/new file paths. Artifact copying is handled by `AgentSession.fork()`:\n\n- attempts recursive copy of old artifact directory to new artifact directory,\n- missing old directory is tolerated,\n- non-ENOENT copy errors are logged as warnings and fork still completes.\n\nID implications after fork:\n\n- if copy succeeded, artifact counters in new session continue after max copied ID,\n- if copy failed/skipped, new session artifact IDs start from `0`.\n\nBlob implications after fork:\n\n- blobs are global and content-addressed, so no blob directory copy is required.\n\n## Move to new cwd\n\n`SessionManager.moveTo()` renames both session file and artifact directory to the new default session directory, with rollback logic if a later step fails. This preserves artifact identity while relocating session scope.\n\n## Failure handling and fallback paths\n\n| Case | Behavior |\n| -------------------------------------------------------- | --------------------------------------------------------------------- |\n| Blob file missing during rehydration | Warn and keep `blob:sha256:` ref string in-memory |\n| Blob read ENOENT via `BlobStore.get` | Returns `null` |\n| Artifact directory missing (`ArtifactManager.listFiles`) | Returns empty list (allocation can start fresh) |\n| Artifact directory missing (`artifact://` / `agent://`) | Throws explicit `No artifacts directory found` |\n| Artifact ID not found | Throws with available IDs listing |\n| OutputSink artifact writer init fails | Continues with tail-only truncation (no full-output artifact) |\n| No session file (some task paths) | Task tool falls back to temp artifacts directory for subagent outputs |\n\n## Binary blob externalization vs text-output artifacts\n\n- **Blob externalization** is for image payloads inside persisted session entry content and provider image data URLs; it replaces inline payload strings in JSONL with stable content refs.\n- **Artifacts** are plain text files for execution output and subagent output; they are addressable by session-local IDs through internal URLs.\n\nThe two systems intersect only indirectly (both reduce session JSONL bloat) but have different identity, lifetime, and retrieval paths.\n\n## Implementation files\n\n- [`src/session/blob-store.ts`](../packages/coding-agent/src/session/blob-store.ts) — blob reference format, hashing, put/get, externalize/resolve helpers.\n- [`src/session/artifacts.ts`](../packages/coding-agent/src/session/artifacts.ts) — session artifact directory model and numeric artifact ID/path allocation.\n- [`src/session/streaming-output.ts`](../packages/coding-agent/src/session/streaming-output.ts) — `OutputSink` truncation/spill-to-file behavior and summary metadata.\n- [`src/session/session-manager.ts`](../packages/coding-agent/src/session/session-manager.ts) — persistence transforms, blob rehydration on load, session fork/move interactions.\n- [`src/session/agent-session.ts`](../packages/coding-agent/src/session/agent-session.ts) — artifact directory copy during interactive fork.\n- [`src/internal-urls/artifact-protocol.ts`](../packages/coding-agent/src/internal-urls/artifact-protocol.ts) — `artifact://` resolver.\n- [`src/internal-urls/agent-protocol.ts`](../packages/coding-agent/src/internal-urls/agent-protocol.ts) — `agent://` resolver + JSON extraction.\n- [`src/sdk/session.ts`](../packages/coding-agent/src/sdk/session.ts) — internal URL router wiring and artifacts-dir resolver.\n- [`src/task/output-manager.ts`](../packages/coding-agent/src/task/output-manager.ts) — session-scoped agent output ID allocation for `agent://`.\n- [`src/task/executor.ts`](../packages/coding-agent/src/task/executor.ts) — subagent output artifact writes (`.md`) and temp artifact directory fallback.\n", - "bot-integration.md": "# External controller integration guide\n\nThis guide is for authors of bots and orchestrators that want to drive Gajae-Code (`gjc`) without scraping terminal scrollback. Hermes, OpenClaw, GitHub bots, chatops bots, and custom schedulers are examples of external controllers; none of them need bespoke GJC behavior if they can speak the Coordinator MCP tools or the SDK WebSocket lifecycle below.\n\nGJC is an external runner. Your controller owns queueing, identity, policy, and credentials; GJC owns the coding-agent session, workflows, tools, artifacts, and evidence inside the selected repository or worktree.\n\n## Integration surfaces\n\nUse the smallest surface that fits your bot:\n\n| Surface | Best for | Command | Stability notes |\n| --- | --- | --- | --- |\n| Coordinator MCP | Any external controller that can discover SDK-backed sessions, send turns, answer questions, and read artifacts. | `gjc mcp-serve coordinator` | Preferred orchestration surface. `gjc mcp-serve hermes` is a compatibility alias, not a separate contract. |\n| Setup adapter | Rendering a portable MCP config and operator instructions for a controller profile. | `gjc setup hermes --root /path/to/repo` | Compatibility-oriented config renderer; does not call an LLM or validate provider credentials. |\n| SDK WebSocket | A controller that drives one live session directly: state queries, events, actions, and workflow-gate replies. | Connect to the session's loopback SDK endpoint (see [`docs/sdk.md`](./sdk.md)) | The canonical machine interface. `--mode rpc`, `--mode rpc-ui`, and `--mode bridge` have been removed. |\n| Daemon session CLI | Scripted control/queries against a live session with JSON output. | `gjc daemon session list\\|control\\|query\\|global` | A pure SDK client; honors the same protocol and dispositions. |\n\n## Recommended architecture\n\n```text\nexternal controller / bot\n ├─ chooses repo/worktree and task policy\n ├─ starts MCP server: gjc mcp-serve coordinator\n ├─ discovers or starts one SDK-backed GJC session\n ├─ sends one bounded turn at a time\n ├─ answers structured questions explicitly\n ├─ marks turn completion/failure with report_status\n └─ reads artifacts/reports from allowlisted roots\n```\n\nDo not infer completion from terminal output.

Its successful JSON payload retains `ok`, `server`, `readOnly`, and `tools`, and adds `catalog: { \"ready\": true, \"reason\": null }` plus `broker`. `broker.discovery_status` is `ready`, `unavailable`, or `error`; its reason is one of `absent_or_invalid`, `unsupported_state_version`, `discovery_access_denied`, or `discovery_read_failed` (or `null` when ready). `broker.operational_ready` is always `null`: this check observes canonical broker discovery but does not connect, ensure/bootstrap, write, repair, or delete. It reports `bootstrap_supported: true` and `bootstrap_attempted: false`, and never exposes broker paths, authority, endpoint, process, token, or raw error details. The human output remains the server/tools summary.

Failure diagnoses that setup; it must not fail CI or PR validation. | Start `gjc mcp-serve coordinator` with local env, dispatch a tiny task, then report/read evidence. |\n\nA public bot integration change should at least preserve the contract smoke and local-leak docs test. Live smokes are diagnostics, not mandatory gates.\n\n## MCP tool contract\n\nRead-only tools:\n\n- `gjc_coordinator_list_sessions`\n- `gjc_coordinator_read_status`\n- `gjc_coordinator_read_tail`\n- `gjc_coordinator_read_turn`\n- `gjc_coordinator_await_turn`\n- `gjc_coordinator_list_questions`\n- `gjc_coordinator_list_artifacts`\n- `gjc_coordinator_read_artifact`\n- `gjc_coordinator_read_coordination_status`\n- `gjc_coordinator_watch_events`\n\nMutating tools:\n\n- `gjc_coordinator_start_session`\n- `gjc_coordinator_register_session`\n- `gjc_coordinator_send_prompt`\n- `gjc_coordinator_submit_question_answer`\n- `gjc_coordinator_report_status`\n- `gjc_coordinator_stop_session`\n\n`gjc_coordinator_stop_session` closes a coordinator delegate-created (ephemeral) session through canonical SDK broker lifecycle control, then removes its coordinator metadata only after the broker reports success. It refuses sessions with an active turn. User-registered sessions require both `force: true` and the `GJC_COORDINATOR_MCP_FORCE_STOP` capability; the same SDK lifecycle path reaps abandoned ephemeral delegate sessions after the configured idle TTL.\n\nHigh-level delegation tools:\n\n- `gjc_delegate_plan`\n- `gjc_delegate_execute`\n- `gjc_delegate_team`\n\nThe `gjc_delegate_*` tools package common GJC workflows for hosts that want to delegate an entire planning, execution, or team turn without manually composing `start_session` and `send_prompt`. They use the same coordinator mutation gates and workdir allowlists as the lower-level session tools.\n\n### Start a managed GJC session\n\nCall `gjc_coordinator_start_session` with a canonical workdir inside `GJC_COORDINATOR_MCP_WORKDIR_ROOTS`:\n\n```json\n{\n \"cwd\": \"/path/to/repo\",\n \"prompt\": \"Optional first bounded task prompt\",\n \"idempotency_key\": \"start-gjc-demo-1\",\n \"allow_mutation\": true\n}\n```\n\nThe returned payload includes `session.session_id`, `session_state`, and, when a prompt is provided, `turn_id`, `active_turn_id`, `status`, `delivery`, `queued`, and `delivered`. The top-level `status`, `queued`, and `delivered` exactly mirror the nested durable turn; `active_turn_id` is the current active turn.\n\n### Register an SDK-discoverable session\n\nRegister an already-running GJC session only after its endpoint is discoverable from the selected workdir:\n\n```json\n{\n \"session_id\": \"visible-gjc-1\",\n \"cwd\": \"/path/to/repo\",\n \"idempotency_key\": \"register-visible-gjc-1\",\n \"allow_mutation\": true\n}\n```\n\n`gjc_coordinator_register_session` validates the session id and workdir allowlist, then verifies SDK endpoint discovery before writing coordinator state. Optional `tmux_session` and `tmux_target` fields are advisory process metadata only.\n\n### Send work as turns\n\nSend one bounded task prompt and persist the returned `turn_id`:\n\n```json\n{\n \"session_id\": \"gjc-demo\",\n \"prompt\": \"Use /skill:ralplan to build a plan for ...\",\n \"idempotency_key\": \"send-gjc-demo-1\",\n \"allow_mutation\": true\n}\n```\n\nA session may have one active turn by default. A second prompt returns `active_turn_exists` unless the bot passes:\n\n- `queue: true` to enqueue a durable follow-up turn, or\n- `force: true` to supersede the previous active turn and audit the supersession.\n\n### Wait or watch for completion\n\nUse `gjc_coordinator_read_turn` for polling or `gjc_coordinator_await_turn` for bounded waiting:\n\n```json\n{\n \"session_id\": \"gjc-demo\",\n \"turn_id\": \"turn-00000000-0000-0000-0000-000000000000\",\n \"timeout_ms\": 30000,\n \"poll_interval_ms\": 1000,\n \"lines\": 80\n}\n```\n\nTerminal turn statuses are `completed`, `failed`, `cancelled`, and `superseded`. Non-terminal statuses include `queued`, `delivering`, `active`, `waiting_for_answer`, and `completing`.\n\nWhen the work is done, your bot must call `gjc_coordinator_report_status` with the turn id. This writes the final response/error, evidence paths, and coordinator report that later reads consume:\n\n```json\n{\n \"session_id\": \"gjc-demo\",\n \"turn_id\": \"turn-00000000-0000-0000-0000-000000000000\",\n \"status\": \"completed\",\n \"summary\": \"Implemented the requested fix and ran focused tests.\",\n \"evidence_paths\": [\"/path/to/repo/test-output.txt\"],\n \"idempotency_key\": \"report-gjc-demo-1\",\n \"allow_mutation\": true\n}\n```\n\nUse `status: \"failed\"` plus `blocker` for provider failures, unrecoverable tool failures, missing credentials, policy denial, or task blockers.\nUse `status: \"cancelled\"` when the coordinator policy intentionally stops tracking an active turn, for example after an operator abort or a bot-side shutdown decision. This records the turn as terminal in coordinator state; it does not kill or control any tmux process. To supersede one active turn with replacement work, send the replacement prompt with `force: true` and preserve the superseded turn id in your audit trail.\n\n### Forward finish/stop lifecycle notifications\n\nDiscord, Hermes, Clawhip, and similar external notifiers should be opt-in and should forward only the public lifecycle surface. Use one of these supported paths:\n\n- Coordinator controllers: watch or poll turn state with `gjc_coordinator_watch_events`, `gjc_coordinator_await_turn`, or `gjc_coordinator_read_turn`, then notify from the terminal turn status your controller records with `gjc_coordinator_report_status`.\n- In-process extensions or hooks: subscribe to the public lifecycle events `turn_end` and `agent_end` from the shared hook/extension event contract.\n\nRecommended notification mapping:\n\n| Notification intent | Public surface | Safe meaning |\n| --- | --- | --- |\n| Turn finished | `turn_end` or terminal coordinator turn status `completed` | One LLM turn produced its final assistant message. |\n| Agent stopped / finished | `agent_end` | The agent loop ended for the submitted prompt. |\n| Waiting for user | Coordinator turn status `waiting_for_answer` | The agent is blocked on a structured question. |\n| Failed or blocked | Coordinator status `failed` with a public `blocker` summary | The controller recorded a terminal failure. |\n| Cancelled / superseded | Coordinator status `cancelled` or `superseded` | The controller intentionally stopped tracking or replaced the turn. |\n\nDo not forward raw prompts, transcripts, tool outputs, hidden instructions, private configs, host paths, channel ids, webhook URLs, or tokens. If your notifier needs a human-readable sentence, create a caller-supplied sanitized summary and keep provider/tool details out of the payload.\n\nExample public-safe extension event payloads:\n\n```json\n{ \"type\": \"turn_end\", \"turnIndex\": 2, \"summary\": \"Turn finished; review the local GJC session for details.\" }\n```\n\n```json\n{ \"type\": \"agent_end\", \"summary\": \"Agent loop ended; no raw transcript is included.\" }\n```\n\nExample opt-in forwarding policy:\n\n```json\n{\n \"enabled\": true,\n \"events\": [\"turn_end\", \"agent_end\"],\n \"destination\": \"external-notifier-profile\",\n \"redaction\": \"metadata-only\"\n}\n```\n\nGJC does not currently expose a structured stop-reason field on `agent_end`; integrators that need `waiting_for_answer`, `failed`, `cancelled`, or `superseded` should prefer the Coordinator MCP turn status because it is explicit, terminal-state oriented, and safe to relay after controller-side redaction.\n\n### Answer structured questions\n\nPull questions for one required session; every call reconciles durable pending `workflow.gates.list` rows before returning a bounded `questions`, `diagnostics`, and `reconciliation` snapshot. Filter `status: \"pending\"`; legacy `status: \"open\"` remains a compatibility alias for pending. A session can return multiple questions, so handle every pending row independently. The public rows include only the safe question shape and a per-pending-row `answer_binding`; they never expose private gate payloads or gate values.\n\n```json\n{ \"session_id\": \"gjc-demo\", \"status\": \"pending\" }\n```\n\nSubmit the exact identifiers and binding from one pending row. `answer` uses public option ids (`opt_0`, etc.), or the advertised `other`/`clarify` form:\n\n```json\n{\n \"session_id\": \"gjc-demo\",\n \"turn_id\": \"turn-00000000-0000-0000-0000-000000000000\",\n \"question_id\": \"question-1\",\n \"answer_binding\": \"\",\n \"answer\": { \"selected\": [\"opt_0\"] },\n \"idempotency_key\": \"answer-gjc-demo-1\",\n \"allow_mutation\": true\n}\n```\n\n`gjc_coordinator_submit_question_answer` requires `session_id`, `turn_id`, `question_id`, `answer_binding`, `answer`, `idempotency_key`, and `allow_mutation: true`; it resolves through `workflow.gate_answer`, never generic `ask.answer`. It revalidates against a complete fresh snapshot after restart and before resolution. Incomplete reconciliation returns `terminal_uncertain`; stale, terminal, absent, or ownership-mismatched rows are not answerable. Retry only an identical request with the same idempotency key: it replays the accepted result; reusing that key with conflicting arguments returns `idempotency_conflict`. Always answer the advertised shape; do not synthesize destructive approvals unless bot policy permits them.\n\nThis Coordinator MCP pull loop is separate from #2549/#2551 and unattended plain-CLI behavior; those paths do not gain coordinator gate access.\n\n### Read artifacts and reports\n\nUse `gjc_coordinator_list_artifacts` to inspect safe roots and `gjc_coordinator_read_artifact` to read a bounded artifact:\n\n```json\n{ \"path\": \"/path/to/repo/.gjc/ultragoal/ledger.jsonl\" }\n```\n\nArtifact paths are canonicalized, symlink escapes are rejected, and output is byte-capped. Use `gjc_coordinator_read_coordination_status` for status reports written through `gjc_coordinator_report_status`.\n\n## SDK WebSocket integration\n\nUse the SDK when your bot owns a single live session rather than an MCP coordinator. Each running session exposes a loopback WebSocket endpoint discovered via `.gjc/state/sdk/.json`; the wire protocol (state queries, control operations, event subscription and replay, workflow-gate replies, reverse host-tool leases) is documented in [`docs/sdk.md`](./sdk.md).\n\nKey SDK workflow-gate facts:\n- The discovery file carries the endpoint URL and per-session token; a wrong\n token is rejected at the WebSocket handshake. `server_hello` marks a\n connection ready, and `gjc daemon session control|query|global` uses the same\n protocol for shell scripts.\n\n- `action_needed.id` is an opaque, transient presentation ID. It is the only\n generic `reply.id` authority. Do not equate it with a durable workflow gate.\n- A durable workflow-gate presentation optionally includes additive SDK v3 `workflowGateId`. It correlates to Q12's durable `gate_id` only within `(sessionId, workflowGateId)` on the current authenticated endpoint; it never authorizes generic reply.\n- `workflow.gate_answer` and `workflow.plan_approve` use the durable `gate_id`. `expectedSessionId` omission remains accepted and audited for the entire SDK v3 line so deployed v3 clients continue to work, but new clients must send it. Mandatory enforcement or removal may occur no earlier than SDK v4 and only after at least one full published deprecation release/window with deployed-client notice. A supplied session mismatch is rejected before resolution.\n- One session has one active answerable presentation. Additional Q12 gates stay queued while Q12 exposes durable pending records and additive SDK v3 diagnostics. A same-server reconnect replays the active action ID; a process restart quarantines old records and a rebuilt workflow remints fresh gate and presentation IDs.\n- A native generic reply claim wins a direct-control race once acquired; a direct control wins only by atomically retiring the exact unclaimed active presentation. Terminal, stale, and reissued action IDs never regain authority. Do not use text, option/order, durable-ID, or history heuristics, and fail closed rather than guess when identity is unsafe or ambiguous. Do not persist private route/claim/receipt/epoch/generation state.\n- Rust/N-API compatibility is additive: legacy `ActionNeeded`, `register_ask`,\n and `registerAsk` stay uncorrelated; explicit workflow reader/registration\n APIs preserve correlation without exposing private arbitration state.\n- The `@gajae-code/coding-agent` runtime and `@gajae-code/natives` native addon ship from the same source release at exact matching package versions; the native loader version sentinel enforces the pair. Mixed native/runtime versions are unsupported and cannot claim SDK compatibility.\n\nThe prior documented invariant `action_needed.id == gate_id` is incorrect for\nv3 and must not be implemented by controllers. See [`docs/sdk.md`](./sdk.md)\nfor exact wire examples, Q12 tags/lifecycle diagnostics, and control payloads.\n\n`--mode rpc`, `--mode rpc-ui`, and `--mode bridge` have been removed along with their JSONL/HTTPS protocols and the former Python RPC client. There are no compatibility shims; migrate controllers to the SDK endpoint or Coordinator MCP.\n\n## Error handling playbook\n\n| Situation | Bot behavior |\n| --- | --- |\n| `coordinator_mutation_class_disabled:*` | Re-render setup with the required mutation class, or keep the bot in read-only mode. |\n| `coordinator_mutation_call_not_allowed:*` | Add `allow_mutation: true` only after policy approval for that specific call. |\n| `unknown_session` | Re-list sessions; start a new managed session or register a session after its SDK endpoint is discoverable. |\n| `active_turn_exists` | Poll the active turn, send with `queue: true`, or use `force: true` only when supersession is intentional. |\n| `timeout` from `await_turn` | Treat as non-terminal. Poll again or inspect `read_status`; do not mark failure solely from a bounded wait timeout. |\n| Coordinator cancellation | Use `gjc_coordinator_report_status` with `status: \"cancelled\"` for an intentionally stopped turn, or send replacement work with `force: true` when supersession is policy-approved. This is coordinator state, not process control. |\n| Stale session state | Check `read_status.session_state` and SDK endpoint discovery. Register a new discoverable session or report the turn failed with a recoverable blocker. |\n| Provider/auth failure | Capture the model/provider error in `report_status` with `status: \"failed\"`; do not retry forever without a policy budget. |\n| Artifact denied | Keep the artifact inside allowlisted roots and avoid symlink escapes. |\n| Malformed or invalid question answer | Re-read the question/gate schema and submit a value matching the advertised shape. |\n| Bot shutdown | Persist `session_id` and active `turn_id`; on restart use `read_turn` and `read_status` before sending more work. |\n\n## Controller examples\n\nGeneric MCP controller config:\n\n```json\n{\n \"mcp_servers\": {\n \"gjc_coordinator\": {\n \"command\": \"gjc\",\n \"args\": [\"mcp-serve\", \"coordinator\"],\n \"env\": {\n \"GJC_COORDINATOR_MCP_WORKDIR_ROOTS\": \"/home/bot/src/project:/home/bot/src/worktrees\",\n \"GJC_COORDINATOR_MCP_MUTATIONS\": \"sessions,questions,reports\",\n \"GJC_COORDINATOR_MCP_PROFILE\": \"controller-prod\",\n \"GJC_COORDINATOR_MCP_REPO\": \"project\",\n \"GJC_COORDINATOR_MCP_SESSION_COMMAND\": \"gjc --worktree\"\n },\n \"enabled\": true\n }\n }\n}\n```\n\nExample controller loop:\n\n```text\n1. Start `gjc mcp-serve coordinator` with repo/worktree roots allowlisted.\n2. Call `gjc_coordinator_start_session` for a GJC-managed worktree session.\n3. Send `/skill:deep-interview`, `/skill:ralplan`, or an approved `gjc ultragoal ...` task as one turn.\n4. Await the turn; answer `gjc_coordinator_list_questions` entries using bot policy.\n5. Report terminal status with evidence paths.\n6. Read artifacts/reports for the user-facing bot response.\n```\n\nHermes and OpenClaw can use the same MCP tool contract. Their names here are examples of controller products, not privileged integration modes.\n\n## Security and credential boundaries\n\n- Do not put provider API keys, GitHub tokens, or bot secrets in prompts.\n- Prefer host tools, host URI schemes, or bot-side sidecars for credentialed external writes.\n- Keep `GJC_COORDINATOR_MCP_WORKDIR_ROOTS` narrow; do not allow `/`, `/home`, or broad parent directories.\n- Use namespaces for multi-tenant bots.\n- Keep mutation classes minimal: read-only for dashboards, `sessions` for work dispatch, `questions` for answering questions, and `reports` for final state.\n- Treat `.gjc/` as local runtime state and evidence. Do not expose it wholesale to untrusted users.\n\n## Related references\n\n- [`docs/hermes-mcp-bridge.md`](./hermes-mcp-bridge.md) — coordinator MCP details and setup adapter behavior.\n- [`docs/sdk.md`](./sdk.md) — SDK wire protocol, event frames, workflow gates, host tools, and host URI schemes.\n- [`docs/external-control-readiness.md`](./external-control-readiness.md) — readiness classification of the supported external-control surfaces.\n", + "bot-integration.md": "# External controller integration guide\n\nThis guide is for authors of bots and orchestrators that want to drive Gajae-Code (`gjc`) without scraping terminal scrollback. Hermes, OpenClaw, GitHub bots, chatops bots, and custom schedulers are examples of external controllers; none of them need bespoke GJC behavior if they can speak the Coordinator MCP tools or the SDK WebSocket lifecycle below.\n\nGJC is an external runner. Your controller owns queueing, identity, policy, and credentials; GJC owns the coding-agent session, workflows, tools, artifacts, and evidence inside the selected repository or worktree.\n\n## Integration surfaces\n\nUse the smallest surface that fits your bot:\n\n| Surface | Best for | Command | Stability notes |\n| --- | --- | --- | --- |\n| Coordinator MCP | Any external controller that can discover SDK-backed sessions, send turns, answer questions, and read artifacts. | `gjc mcp-serve coordinator` | Preferred orchestration surface. `gjc mcp-serve hermes` is a compatibility alias, not a separate contract. |\n| Setup adapter | Rendering a portable MCP config and operator instructions for a controller profile. | `gjc setup hermes --root /path/to/repo` | Compatibility-oriented config renderer; does not call an LLM or validate provider credentials. |\n| SDK WebSocket | A controller that drives one live session directly: state queries, events, actions, and workflow-gate replies. | Connect to the session's loopback SDK endpoint (see [`docs/sdk.md`](./sdk.md)) | The canonical machine interface. `--mode rpc`, `--mode rpc-ui`, and `--mode bridge` have been removed. |\n| Daemon session CLI | Scripted control/queries against a live session with JSON output. | `gjc daemon session list\\|control\\|query\\|global` | A pure SDK client; honors the same protocol and dispositions. |\n\n## Recommended architecture\n\n```text\nexternal controller / bot\n ├─ chooses repo/worktree and task policy\n ├─ starts MCP server: gjc mcp-serve coordinator\n ├─ discovers or starts one SDK-backed GJC session\n ├─ sends one bounded turn at a time\n ├─ answers structured questions explicitly\n ├─ marks turn completion/failure with report_status\n └─ reads artifacts/reports from allowlisted roots\n```\n\nDo not infer completion from terminal output. Treat SDK-backed durable turn state as authoritative. Tmux identifiers, when present, are advisory process metadata only.\n\n## Coordinator MCP setup\n\nRender a non-mutating config preview:\n\n```sh\ngjc setup hermes --root /path/to/repo --profile my-bot --repo my-repo\n```\n\nInstall into a Hermes-compatible profile only when the target path is intentional:\n\n```sh\ngjc setup hermes \\\n --root /path/to/repo \\\n --profile my-bot \\\n --repo my-repo \\\n --mutation sessions,questions,reports \\\n --profile-dir /path/to/hermes/profile \\\n --install\n```\n\nRun provider-independent contract smokes before trying a live model:\n\n```sh\ngjc setup hermes --root /path/to/repo --smoke --json\ngjc mcp-serve coordinator --check --json\n```\n\n`gjc mcp-serve coordinator --check --json` (and the `hermes` compatibility alias) is a discovery-only, non-mutating catalog check. Its successful JSON payload retains `ok`, `server`, `readOnly`, and `tools`, and adds `catalog: { \"ready\": true, \"reason\": null }` plus `broker`. `broker.discovery_status` is `ready`, `unavailable`, or `error`; its reason is one of `absent_or_invalid`, `unsupported_state_version`, `discovery_access_denied`, or `discovery_read_failed` (or `null` when ready). `broker.operational_ready` is always `null`: this check observes canonical broker discovery but does not connect, ensure/bootstrap, write, repair, or delete. It reports `bootstrap_supported: true` and `bootstrap_attempted: false`, and never exposes broker paths, authority, endpoint, process, token, or raw error details. The human output remains the server/tools summary. SDK check behavior is separate and unchanged.\n\nThe generated config uses these environment variables:\n\n| Variable | Purpose |\n| --- | --- |\n| `GJC_COORDINATOR_MCP_WORKDIR_ROOTS` | Required allowlist for workdirs and artifact paths. |\n| `GJC_COORDINATOR_MCP_MUTATIONS` | Startup opt-in for mutation classes: `sessions`, `questions`, `reports`, or `all`. |\n| `GJC_COORDINATOR_MCP_SESSION_COMMAND` | Command used to start real GJC sessions, defaulting to `gjc --worktree` in generated setup. |\n| `GJC_COORDINATOR_MCP_PROFILE` | Optional profile namespace so one bot cannot enumerate another profile's state. |\n| `GJC_COORDINATOR_MCP_REPO` | Optional repo namespace so one repo cannot enumerate another repo's state. |\n| `GJC_COORDINATOR_MCP_STATE_ROOT` | Optional coordination state root; defaults under `.gjc/state/coordinator-mcp`. |\n| `GJC_COORDINATOR_MCP_ARTIFACT_BYTE_CAP` | Maximum bytes returned by artifact reads. |\n\nMutating calls require both startup opt-in, per-call `allow_mutation: true`, and the required caller-provided `idempotency_key`. Missing any one fails closed.\n\n## Generic smoke strategy\n\nUse three different smoke levels so CI does not depend on one operator's model, API key, or desktop:\n\n| Smoke | Required for CI | What it proves | Example |\n| --- | --- | --- | --- |\n| Contract smoke | Yes | MCP server metadata, tool discovery, exported tool names, input schemas, read-only default, and mutation-gate failures.

Live smokes are diagnostics, not mandatory gates.\n\n## MCP tool contract\n\nRead-only tools:\n\n- `gjc_coordinator_list_sessions`\n- `gjc_coordinator_read_status`\n- `gjc_coordinator_read_tail`\n- `gjc_coordinator_read_turn`\n- `gjc_coordinator_await_turn`\n- `gjc_coordinator_list_questions`\n- `gjc_coordinator_list_artifacts`\n- `gjc_coordinator_read_artifact`\n- `gjc_coordinator_read_coordination_status`\n- `gjc_coordinator_watch_events`\n- `gjc_coordinator_read_codex_handoff` — reads the Codex app-server resume bridge registration and durable wake state; endpoints are unix sockets or loopback TCP only, and token-file references only. Returned wake events expose lifecycle schema version 1 (`pending` → `requested`, `published` → `delivered`, `acked` → `acknowledged`, `failed` → `failed`); durable `attempts` and `last_error` are its failure/retry metadata. Heartbeats are unsupported (`automation_update_unavailable`), so delivery remains event-driven with startup drain.\n\nMutating tools:\n\n- `gjc_coordinator_start_session`\n- `gjc_coordinator_register_session`\n- `gjc_coordinator_send_prompt`\n- `gjc_coordinator_submit_question_answer`\n- `gjc_coordinator_report_status`\n- `gjc_coordinator_stop_session`\n- `gjc_coordinator_register_codex_handoff` — registers the Codex app-server resume bridge with a unix/loopback endpoint and token-file reference only.\n- `gjc_coordinator_ack_codex_handoff` — acknowledges a Codex resume wake by durable `wake_key`; wake prompts never include GJC final responses.\n\n`gjc_coordinator_stop_session` closes a coordinator delegate-created (ephemeral) session through canonical SDK broker lifecycle control, then removes its coordinator metadata only after the broker reports success. It refuses sessions with an active turn. User-registered sessions require both `force: true` and the `GJC_COORDINATOR_MCP_FORCE_STOP` capability; the same SDK lifecycle path reaps abandoned ephemeral delegate sessions after the configured idle TTL.\n\nHigh-level delegation tools:\n\n- `gjc_delegate_plan`\n- `gjc_delegate_execute`\n- `gjc_delegate_team`\n\nThe `gjc_delegate_*` tools package common GJC workflows for hosts that want to delegate an entire planning, execution, or team turn without manually composing `start_session` and `send_prompt`.

The top-level `status`, `queued`, and `delivered` exactly mirror the nested durable turn; `active_turn_id` is the current active turn.\n\n### Register an SDK-discoverable session\n\nRegister an already-running GJC session only after its endpoint is discoverable from the selected workdir:\n\n```json\n{\n \"session_id\": \"visible-gjc-1\",\n \"cwd\": \"/path/to/repo\",\n \"idempotency_key\": \"register-visible-gjc-1\",\n \"allow_mutation\": true\n}\n```\n\n`gjc_coordinator_register_session` validates the session id and workdir allowlist, then verifies SDK endpoint discovery before writing coordinator state.

A second prompt returns `active_turn_exists` unless the bot passes:\n\n- `queue: true` to enqueue a durable follow-up turn, or\n- `force: true` to supersede the previous active turn and audit the supersession.\n\n### Wait or watch for completion\n\nUse `gjc_coordinator_read_turn` for polling or `gjc_coordinator_await_turn` for bounded waiting:\n\n```json\n{\n \"session_id\": \"gjc-demo\",\n \"turn_id\": \"turn-00000000-0000-0000-0000-000000000000\",\n \"timeout_ms\": 30000,\n \"poll_interval_ms\": 1000,\n \"lines\": 80\n}\n```\n\nTerminal turn statuses are `completed`, `failed`, `cancelled`, and `superseded`. Non-terminal statuses include `queued`, `delivering`, `active`, `waiting_for_answer`, and `completing`.\n\nWhen the work is done, your bot must call `gjc_coordinator_report_status` with the turn id. This writes the final response/error, evidence paths, and coordinator report that later reads consume:\n\n```json\n{\n \"session_id\": \"gjc-demo\",\n \"turn_id\": \"turn-00000000-0000-0000-0000-000000000000\",\n \"status\": \"completed\",\n \"summary\": \"Implemented the requested fix and ran focused tests.\",\n \"evidence_paths\": [\"/path/to/repo/test-output.txt\"],\n \"idempotency_key\": \"report-gjc-demo-1\",\n \"allow_mutation\": true\n}\n```\n\nUse `status: \"failed\"` plus `blocker` for provider failures, unrecoverable tool failures, missing credentials, policy denial, or task blockers.\nUse `status: \"cancelled\"` when the coordinator policy intentionally stops tracking an active turn, for example after an operator abort or a bot-side shutdown decision. This records the turn as terminal in coordinator state; it does not kill or control any tmux process. To supersede one active turn with replacement work, send the replacement prompt with `force: true` and preserve the superseded turn id in your audit trail.\n\n### Forward finish/stop lifecycle notifications\n\nDiscord, Hermes, Clawhip, and similar external notifiers should be opt-in and should forward only the public lifecycle surface. Use one of these supported paths:\n\n- Coordinator controllers: watch or poll turn state with `gjc_coordinator_watch_events`, `gjc_coordinator_await_turn`, or `gjc_coordinator_read_turn`, then notify from the terminal turn status your controller records with `gjc_coordinator_report_status`.\n- In-process extensions or hooks: subscribe to the public lifecycle events `turn_end` and `agent_end` from the shared hook/extension event contract.\n\nRecommended notification mapping:\n\n| Notification intent | Public surface | Safe meaning |\n| --- | --- | --- |\n| Turn finished | `turn_end` or terminal coordinator turn status `completed` | One LLM turn produced its final assistant message. |\n| Agent stopped / finished | `agent_end` | The agent loop ended for the submitted prompt. |\n| Waiting for user | Coordinator turn status `waiting_for_answer` | The agent is blocked on a structured question. |\n| Failed or blocked | Coordinator status `failed` with a public `blocker` summary | The controller recorded a terminal failure. |\n| Cancelled / superseded | Coordinator status `cancelled` or `superseded` | The controller intentionally stopped tracking or replaced the turn. |\n\nDo not forward raw prompts, transcripts, tool outputs, hidden instructions, private configs, host paths, channel ids, webhook URLs, or tokens. If your notifier needs a human-readable sentence, create a caller-supplied sanitized summary and keep provider/tool details out of the payload.\n\nExample public-safe extension event payloads:\n\n```json\n{ \"type\": \"turn_end\", \"turnIndex\": 2, \"summary\": \"Turn finished; review the local GJC session for details.\" }\n```\n\n```json\n{ \"type\": \"agent_end\", \"summary\": \"Agent loop ended; no raw transcript is included.\" }\n```\n\nExample opt-in forwarding policy:\n\n```json\n{\n \"enabled\": true,\n \"events\": [\"turn_end\", \"agent_end\"],\n \"destination\": \"external-notifier-profile\",\n \"redaction\": \"metadata-only\"\n}\n```\n\nGJC does not currently expose a structured stop-reason field on `agent_end`; integrators that need `waiting_for_answer`, `failed`, `cancelled`, or `superseded` should prefer the Coordinator MCP turn status because it is explicit, terminal-state oriented, and safe to relay after controller-side redaction.\n\n### Answer structured questions\n\nPull questions for one required session; every call reconciles durable pending `workflow.gates.list` rows before returning a bounded `questions`, `diagnostics`, and `reconciliation` snapshot. Filter `status: \"pending\"`; legacy `status: \"open\"` remains a compatibility alias for pending. A session can return multiple questions, so handle every pending row independently. The public rows include only the safe question shape and a per-pending-row `answer_binding`; they never expose private gate payloads or gate values.\n\n```json\n{ \"session_id\": \"gjc-demo\", \"status\": \"pending\" }\n```\n\nSubmit the exact identifiers and binding from one pending row. `answer` uses public option ids (`opt_0`, etc.), or the advertised `other`/`clarify` form:\n\n```json\n{\n \"session_id\": \"gjc-demo\",\n \"turn_id\": \"turn-00000000-0000-0000-0000-000000000000\",\n \"question_id\": \"question-1\",\n \"answer_binding\": \"\",\n \"answer\": { \"selected\": [\"opt_0\"] },\n \"idempotency_key\": \"answer-gjc-demo-1\",\n \"allow_mutation\": true\n}\n```\n\n`gjc_coordinator_submit_question_answer` requires `session_id`, `turn_id`, `question_id`, `answer_binding`, `answer`, `idempotency_key`, and `allow_mutation: true`; it resolves through `workflow.gate_answer`, never generic `ask.answer`. It revalidates against a complete fresh snapshot after restart and before resolution. Incomplete reconciliation returns `terminal_uncertain`; stale, terminal, absent, or ownership-mismatched rows are not answerable. Retry only an identical request with the same idempotency key: it replays the accepted result; reusing that key with conflicting arguments returns `idempotency_conflict`. Always answer the advertised shape; do not synthesize destructive approvals unless bot policy permits them.\n\nThis Coordinator MCP pull loop is separate from #2549/#2551 and unattended plain-CLI behavior; those paths do not gain coordinator gate access.\n\n### Read artifacts and reports\n\nUse `gjc_coordinator_list_artifacts` to inspect safe roots and `gjc_coordinator_read_artifact` to read a bounded artifact:\n\n```json\n{ \"path\": \"/path/to/repo/.gjc/ultragoal/ledger.jsonl\" }\n```\n\nArtifact paths are canonicalized, symlink escapes are rejected, and output is byte-capped. Use `gjc_coordinator_read_coordination_status` for status reports written through `gjc_coordinator_report_status`.\n\n## SDK WebSocket integration\n\nUse the SDK when your bot owns a single live session rather than an MCP coordinator. Each running session exposes a loopback WebSocket endpoint discovered via `.gjc/state/sdk/.json`; the wire protocol (state queries, control operations, event subscription and replay, workflow-gate replies, reverse host-tool leases) is documented in [`docs/sdk.md`](./sdk.md).\n\nKey SDK workflow-gate facts:\n- The discovery file carries the endpoint URL and per-session token; a wrong\n token is rejected at the WebSocket handshake. `server_hello` marks a\n connection ready, and `gjc daemon session control|query|global` uses the same\n protocol for shell scripts.\n\n- `action_needed.id` is an opaque, transient presentation ID. It is the only\n generic `reply.id` authority. Do not equate it with a durable workflow gate.\n- A durable workflow-gate presentation optionally includes additive SDK v3 `workflowGateId`. It correlates to Q12's durable `gate_id` only within `(sessionId, workflowGateId)` on the current authenticated endpoint; it never authorizes generic reply.\n- `workflow.gate_answer` and `workflow.plan_approve` use the durable `gate_id`. `expectedSessionId` omission remains accepted and audited for the entire SDK v3 line so deployed v3 clients continue to work, but new clients must send it. Mandatory enforcement or removal may occur no earlier than SDK v4 and only after at least one full published deprecation release/window with deployed-client notice. A supplied session mismatch is rejected before resolution.\n- One session has one active answerable presentation. Additional Q12 gates stay queued while Q12 exposes durable pending records and additive SDK v3 diagnostics. A same-server reconnect replays the active action ID; a process restart quarantines old records and a rebuilt workflow remints fresh gate and presentation IDs.\n- A native generic reply claim wins a direct-control race once acquired; a direct control wins only by atomically retiring the exact unclaimed active presentation. Terminal, stale, and reissued action IDs never regain authority. Do not use text, option/order, durable-ID, or history heuristics, and fail closed rather than guess when identity is unsafe or ambiguous. Do not persist private route/claim/receipt/epoch/generation state.\n- Rust/N-API compatibility is additive: legacy `ActionNeeded`, `register_ask`,\n and `registerAsk` stay uncorrelated; explicit workflow reader/registration\n APIs preserve correlation without exposing private arbitration state.\n- The `@gajae-code/coding-agent` runtime and `@gajae-code/natives` native addon ship from the same source release at exact matching package versions; the native loader version sentinel enforces the pair. Mixed native/runtime versions are unsupported and cannot claim SDK compatibility.\n\nThe prior documented invariant `action_needed.id == gate_id` is incorrect for\nv3 and must not be implemented by controllers. See [`docs/sdk.md`](./sdk.md)\nfor exact wire examples, Q12 tags/lifecycle diagnostics, and control payloads.\n\n`--mode rpc`, `--mode rpc-ui`, and `--mode bridge` have been removed along with their JSONL/HTTPS protocols and the former Python RPC client. There are no compatibility shims; migrate controllers to the SDK endpoint or Coordinator MCP.\n\n## Error handling playbook\n\n| Situation | Bot behavior |\n| --- | --- |\n| `coordinator_mutation_class_disabled:*` | Re-render setup with the required mutation class, or keep the bot in read-only mode. |\n| `coordinator_mutation_call_not_allowed:*` | Add `allow_mutation: true` only after policy approval for that specific call. |\n| `unknown_session` | Re-list sessions; start a new managed session or register a session after its SDK endpoint is discoverable. |\n| `active_turn_exists` | Poll the active turn, send with `queue: true`, or use `force: true` only when supersession is intentional. |\n| `timeout` from `await_turn` | Treat as non-terminal. Poll again or inspect `read_status`; do not mark failure solely from a bounded wait timeout. |\n| Coordinator cancellation | Use `gjc_coordinator_report_status` with `status: \"cancelled\"` for an intentionally stopped turn, or send replacement work with `force: true` when supersession is policy-approved. This is coordinator state, not process control. |\n| Stale session state | Check `read_status.session_state` and SDK endpoint discovery. Register a new discoverable session or report the turn failed with a recoverable blocker. |\n| Provider/auth failure | Capture the model/provider error in `report_status` with `status: \"failed\"`; do not retry forever without a policy budget. |\n| Artifact denied | Keep the artifact inside allowlisted roots and avoid symlink escapes. |\n| Malformed or invalid question answer | Re-read the question/gate schema and submit a value matching the advertised shape. |\n| Bot shutdown | Persist `session_id` and active `turn_id`; on restart use `read_turn` and `read_status` before sending more work. |\n\n## Controller examples\n\nGeneric MCP controller config:\n\n```json\n{\n \"mcp_servers\": {\n \"gjc_coordinator\": {\n \"command\": \"gjc\",\n \"args\": [\"mcp-serve\", \"coordinator\"],\n \"env\": {\n \"GJC_COORDINATOR_MCP_WORKDIR_ROOTS\": \"/home/bot/src/project:/home/bot/src/worktrees\",\n \"GJC_COORDINATOR_MCP_MUTATIONS\": \"sessions,questions,reports\",\n \"GJC_COORDINATOR_MCP_PROFILE\": \"controller-prod\",\n \"GJC_COORDINATOR_MCP_REPO\": \"project\",\n \"GJC_COORDINATOR_MCP_SESSION_COMMAND\": \"gjc --worktree\"\n },\n \"enabled\": true\n }\n }\n}\n```\n\nExample controller loop:\n\n```text\n1. Start `gjc mcp-serve coordinator` with repo/worktree roots allowlisted.\n2. Call `gjc_coordinator_start_session` for a GJC-managed worktree session.\n3. Send `/skill:deep-interview`, `/skill:ralplan`, or an approved `gjc ultragoal ...` task as one turn.\n4. Await the turn; answer `gjc_coordinator_list_questions` entries using bot policy.\n5. Report terminal status with evidence paths.\n6. Read artifacts/reports for the user-facing bot response.\n```\n\nHermes and OpenClaw can use the same MCP tool contract. Their names here are examples of controller products, not privileged integration modes.\n\n## Security and credential boundaries\n\n- Do not put provider API keys, GitHub tokens, or bot secrets in prompts.\n- Prefer host tools, host URI schemes, or bot-side sidecars for credentialed external writes.\n- Keep `GJC_COORDINATOR_MCP_WORKDIR_ROOTS` narrow; do not allow `/`, `/home`, or broad parent directories.\n- Use namespaces for multi-tenant bots.\n- Keep mutation classes minimal: read-only for dashboards, `sessions` for work dispatch, `questions` for answering questions, and `reports` for final state.\n- Treat `.gjc/` as local runtime state and evidence. Do not expose it wholesale to untrusted users.\n\n## Related references\n\n- [`docs/hermes-mcp-bridge.md`](./hermes-mcp-bridge.md) — coordinator MCP details and setup adapter behavior.\n- [`docs/sdk.md`](./sdk.md) — SDK wire protocol, event frames, workflow gates, host tools, and host URI schemes.\n- [`docs/external-control-readiness.md`](./external-control-readiness.md) — readiness classification of the supported external-control surfaces.\n", "brand-assets.md": "# Brand assets\n\nGajae-Code uses the current GJC character and hero images in `assets/` for README and documentation surfaces.\n\n| Asset | Purpose |\n| --- | --- |\n| [`assets/logo-vertical.png`](../assets/logo-vertical.png) | Vertical README/docs logo lockup for Gajae-Code. |\n| [`assets/hero.png`](../assets/hero.png) | Wide README/docs hero image for Gajae-Code. |\n| [`assets/character.png`](../assets/character.png) | Standalone Gajae-Code character mascot. |\n| [`assets/rlm.png`](../assets/rlm.png) | Feature card for the `rlm` research/REPL mode (scientist mascot). |\n| [`assets/computer-use.png`](../assets/computer-use.png) | Feature card for the `computer-use` desktop-control surface (operator mascot). |\n| [`assets/telegram-mobile-hero.png`](../assets/telegram-mobile-hero.png) | Feature card for the Telegram/mobile notifications flow. |\n| [`assets/tool-image-fixture.webp`](../assets/tool-image-fixture.webp) | Minimal WebP fixture for terminal image rendering tests.

The root README stays intentionally small; this file is the architecture-oriented companion.\n\n## Product shape\n\nGajae-Code (`gjc`) is centered on `packages/coding-agent/`. The public workflow surface is intentionally fixed at four source-bundled skills and four public role subagents. Runtime state, specs, plans, goals, team state, and local overrides live under `.gjc/`.\n\nDefault workflow skills are embedded from:\n\n```text\npackages/coding-agent/src/defaults/gjc/skills//SKILL.md\n```\n\nPublic role subagent prompts are embedded from:\n\n```text\npackages/coding-agent/src/prompts/agents/.md\n```\n\nThe runtime can still discover project/user overrides, but the bundled defaults are loaded from source so a missing project `.gjc` directory does not remove the default workflow surface.\n\n## Packages\n\n### `packages/coding-agent/`\n\nMain `gjc` CLI and product runtime.\n\n- `packages/coding-agent/package.json` exposes the `gjc` binary at `src/cli.ts` and the SDK/barrel entrypoint at `src/index.ts`.\n- `packages/coding-agent/src/cli.ts` is the executable bootstrap. It registers CLI commands such as `setup`, `deep-interview`, `ralplan`, `ultragoal`, `team`, and the default launch path.\n- `packages/coding-agent/src/main.ts` adapts CLI options into session creation and dispatches interactive, print, and ACP modes; external machine clients use the SDK WebSocket interface.\n- `packages/coding-agent/src/sdk/session.ts` assembles settings, model registry, auth, workspace/context discovery, skills, rules, tools, system prompt, and the underlying `@gajae-code/agent-core` agent.\n- `packages/coding-agent/src/tools/index.ts` is the built-in tool registry for file/code/runtime tools such as read, bash, edit, AST tools, eval, find/search, LSP, browser, task/subagent, recipe, IRC, todo, web search, and write. Memory backends are private integrations, not public coding-harness tools.\n- `packages/coding-agent/src/defaults/gjc-defaults.ts` embeds and installs the default workflow skills.\n- `packages/coding-agent/src/task/agents.ts` embeds bundled task-agent prompts. The public contract is `executor`, `architect`, `planner`, and `critic`; other bundled prompts are internal/runtime utilities.\n- `packages/coding-agent/src/coordinator/contract.ts` defines the transport-neutral third-party coordinator contract used by `gjc mcp-serve coordinator`, `gjc coordinator`, and `gjc setup hermes`.\n- `packages/coding-agent/src/coordinator-mcp/server.ts` implements the outward MCP adapter for bot/coordinator integrations, including session start/register, turn state, question answering, status reports, and artifact reads.\n- `docs/external-control-readiness.md` classifies the public external-control surfaces: SDK WebSocket for live session control, Coordinator MCP for multi-session control planes, and ACP for editor/ACP clients. `docs/bot-integration.md` is the end-to-end guide for external controller authors.\n\n### `packages/ai/`\n\nProvider/model boundary for LLM access.\n\n- `packages/ai/src/index.ts` exports model registry/resolution, provider implementations, auth broker/gateway/storage, streaming, usage, retry/overflow utilities, OAuth, discovery, and validation helpers.\n- `packages/ai/src/types.ts` defines provider, model, context, message, tool, usage, reasoning, and stream-event contracts.\n- `packages/ai/src/stream.ts` dispatches model-driven streams to the right provider/API implementation and normalizes streaming events.\n- `packages/ai/src/model-manager.ts` merges static, cached, dynamic, and remote model sources.\n- `packages/ai/README.md` documents tool calling, partial streaming tool calls, thinking/reasoning, provider configuration, context handoff, and OAuth flows.\n\n### `packages/agent/`\n\nStateful agent runtime built on `@gajae-code/ai`.\n\n- `packages/agent/src/index.ts` exports the `Agent`, loop APIs, append-only context, compaction, telemetry, proxy utilities, thinking helpers, and shared types.\n- `packages/agent/src/agent-loop.ts` owns the turn loop: transform context, call the model stream, execute tool calls, append tool results, and emit lifecycle events.\n- `packages/agent/src/agent.ts` wraps the loop with mutable state, subscriptions, prompt/continue/abort APIs, queues, provider session state, telemetry, and state mutation helpers.\n- `packages/agent/src/types.ts` defines `AgentMessage`, `AgentTool`, loop config, event, and runtime state contracts.\n\n### `packages/tui/`\n\nTerminal UI framework used by the CLI.\n\n- `packages/tui/src/index.ts` exports components, keybindings, autocomplete, terminal abstractions, image support, TUI core, and utilities.\n- `packages/tui/src/tui.ts` manages component rendering, focus, overlays, terminal dimensions, diff state, and synchronized output.\n- `packages/tui/src/terminal.ts` abstracts terminal lifecycle, dimensions, cursor controls, title/progress, Kitty protocol state, and appearance notifications.\n- `packages/tui/README.md` documents the component model and built-in components such as text, input, editor, markdown, loaders, select/settings lists, spacer, image, box, and container.\n\n### `packages/natives/` and Rust crates\n\nNative helper layer exposed through N-API.\n\n- `packages/natives/package.json` exports `native/index.js` and generated TypeScript definitions.\n- `packages/natives/native/loader-state.js` resolves platform/CPU-specific native binaries and validates package/native version alignment.\n- `crates/pi-natives/src/lib.rs` is the N-API root for appearance, AST search/editing, clipboard, filesystem scan/cache, grep/glob, syntax highlighting, HTML-to-Markdown, keyboard parsing, process/PTY/shell support, SIXEL, code summarization, token counting, text measurement/wrapping/truncation, workspace scanning, power assertions, and isolation helpers.\n- `crates/pi-shell/src/lib.rs` exposes brush-based shell execution primitives used by the native shell adapter.\n- `crates/pi-shell/src/shell.rs` implements persistent and one-shot shell execution, streaming, environment handling, cancellation, and output minimizer telemetry.\n- `crates/pi-shell/src/fixup.rs` performs conservative AST-based bash command fixups.\n- `crates/pi-natives/src/pty.rs` implements interactive PTY sessions.\n\n### `packages/utils/`\n\nShared TypeScript utilities.\n\n- `packages/utils/src/index.ts` exports abortable/async helpers, color/env/dir utilities, fetch retry, formatting, frontmatter, glob helpers, JSON helpers, logging, MIME detection, prompt rendering, process-tree helpers, sanitization, streams, temp files, tab spacing, type guards, and executable lookup.\n- `packages/utils/src/ptree.ts` and `packages/utils/src/procmgr.ts` wrap native process helpers for ergonomic TypeScript use.\n\n### `packages/stats/`\n\nLocal observability dashboard for session and model usage.\n\n- `packages/stats/src/index.ts` exposes the `gjc-stats` CLI entrypoint and exports aggregation/server APIs.\n- `packages/stats/src/aggregator.ts` parses session-derived request metrics and writes aggregated data through SQLite.\n- `packages/stats/src/server.ts` serves local dashboard API routes and static SPA assets.\n- `packages/stats/src/types.ts` and `packages/stats/src/shared-types.ts` define dashboard and aggregate metric shapes.\n\n### `packages/typescript-edit-benchmark/`\n\nPrivate benchmark package for TypeScript edit tasks.\n\n- `packages/typescript-edit-benchmark/package.json` exposes `typescript-edit-benchmark` and depends on the coding-agent, agent-core, ai, tui, utils, diff, prettier, and Babel tooling.\n- `packages/typescript-edit-benchmark/src/index.ts` is the benchmark CLI: it resolves fixtures, loads tasks, runs edit attempts, records progress, and writes reports/conversation dumps under `runs/`.\n\n## Python packages\n\n### External machine interfaces\n\nExternal machine clients use the SDK WebSocket interface documented in `docs/sdk.md`. Coordinator MCP supplies multi-session orchestration, while ACP remains the stdio editor protocol. The former Python RPC client and bot integration paths were removed with the RPC ingress mode.\n\n## Runtime flow\n\nA normal CLI session starts in `packages/coding-agent/src/cli.ts`, routes through command handling, then reaches `packages/coding-agent/src/main.ts`. `main.ts` converts CLI/runtime settings into `CreateAgentSessionOptions` and calls `createAgentSession()` in `packages/coding-agent/src/sdk/session.ts`.\n\nThe SDK builds the session context, loads the default skills, creates built-in tools, resolves model/auth state through `@gajae-code/ai`, constructs the system prompt, and instantiates `@gajae-code/agent-core`. The agent loop streams model events, executes tools, records tool results, and hands state back to the selected interactive TUI, print, or ACP mode while exposing external control through the SDK WebSocket interface.\n\n## Verification and gates\n\nPackage-local checks are defined in each `package.json`. For workflow-definition or default-surface changes, the focused gates are:\n\n```sh\nbun scripts/check-visible-definitions.ts\nbun scripts/verify-g002-gates.ts\nbun scripts/rebrand-inventory.ts --strict\nbun test packages/coding-agent/test/default-gjc-definitions.test.ts\n```\n\nFor broader TypeScript verification, use the root script:\n\n```sh\nbun run check:ts\n```\n\nDo not use `tsc` or `npx tsc` directly in this repository.\n", "codegraph-custom-tool.md": "# CodeGraph as a custom tool\n\n[CodeGraph](https://github.com/colbymchenry/codegraph) is a local, language-agnostic\ncode knowledge graph for AI agents. It pre-indexes symbols, call edges, and\ndependencies in a project so an agent can answer structural questions (\"how does X\nwork\", \"who calls X\", \"what breaks if I change X\") in a few graph queries instead\nof crawling files with `search`/`read`.\n\nThis guide shows how to wire CodeGraph into GJC through the **custom-tool extension\npath** — no core changes, no built-in provider. GJC intentionally keeps third-party\nCLI integrations like this in the user/project extension layer rather than bundling\nthem, so you own the integration and its lifecycle.\n\n> CodeGraph integrates with other agents over MCP, but this guide wires it as a GJC\n> custom tool around CodeGraph's local **CLI** — it does not add an MCP server or a\n> built-in provider. For how GJC treats MCP servers in standalone sessions, see\n> [`standalone-mcp.md`](standalone-mcp.md).\n\n## 1. Install and index\n\n```bash\n# Install the CodeGraph CLI (or use the install script from CodeGraph's README).\nnpm i -g @colbymchenry/codegraph\n\n# Build the local index for a project.\ncd your-project\ncodegraph init\n```\n\n`codegraph init` creates a local `.codegraph/` directory. No data leaves your\nmachine — it is a local SQLite index.\n\n## 2. Add the custom tool\n\nGJC discovers custom tools from a `tools/` directory in its config dirs:\n\n- **Project-scoped**: `/.gjc/tools/`\n- **User-scoped (all projects)**: `~/.gjc/agent/tools/`\n\nA `*.ts` tool file's default export is a factory `(pi) => CustomTool`. The factory\nreceives an API (`pi`) with members such as `exec`, `cwd`, `zod`, and `logger` — so\nthe tool needs no imports from GJC internals.\n\nSave the following as `.gjc/tools/codegraph.ts` (project) or\n`~/.gjc/agent/tools/codegraph.ts` (user):\n\n```typescript\n/**\n * CodeGraph custom tool for gajae-code (GJC).\n *\n * Wraps the local CodeGraph CLI (https://github.com/colbymchenry/codegraph) so the\n * agent can query a project's code knowledge graph instead of crawling files.\n *\n * It only runs CodeGraph's query-style (read-only) subcommands and never edits your\n * source files.

It is erased at runtime, so the tool loads fine\nwithout it.\n\n## 3. Use it\n\nStart GJC in the project. The `codegraph` tool is now available to the model. Ask\na structural question and it will call the tool, for example:\n\n- `codegraph` with `{ \"op\": \"explore\", \"target\": \"how requests are routed\" }` can\n return relevant source plus graph context in one call.\n- `{ \"op\": \"callers\", \"target\": \"MyClass.handle\" }` lists callers.\n- `{ \"op\": \"impact\", \"target\": \"parseConfig\" }` shows what a change would affect.\n- `{ \"op\": \"status\" }` reports index health.\n\n## Operations\n\n| `op` | `target` | Description |\n| --- | --- | --- |\n| `explore` | natural-language query | Context query: relevant symbols' source plus graph context (CodeGraph's `explore`). `maxFiles` caps included source. |\n| `search` | query | Full-text symbol search (`limit`, default 10). |\n| `callers` | symbol | Functions/methods that call the symbol, including dynamic dispatch. |\n| `callees` | symbol | Functions/methods the symbol calls. |\n| `impact` | symbol | Blast radius of changing the symbol. |\n| `status` | — | Index health: file/node/edge counts, languages, pending sync. |\n\n## Notes\n\n- **Read-only with respect to your code.** The tool only runs CodeGraph's\n query-style subcommands; it never edits your files and does not run indexing or\n sync commands. CodeGraph maintains its own local `.codegraph/` index via its CLI.\n If results look stale or `status` reports pending changes, refresh the index with\n CodeGraph's CLI (e.g. `codegraph sync`) outside GJC.\n- **Safe argument handling.** The example spawns CodeGraph with argv arrays via\n `pi.exec` (no shell), `op` is constrained to a fixed enum, and numeric inputs are\n capped — there is no shell interpolation of model-provided values.\n- **Scope.** Use a project-scoped file to limit the tool to one repo, or a\n user-scoped file to make it available everywhere `codegraph init` has been run.\n- **Naming.** The tool registers as `codegraph`; rename it in the file if it\n collides with another tool in your setup.\n- **Fallback.** If the graph reports a symbol is missing, a file is flagged as\n pending sync, or you need a non-structural text search, refresh the CodeGraph\n index outside GJC or fall back to `read`/`search`.\n- For background on how GJC treats external tools and MCP servers in standalone\n sessions, see [`standalone-mcp.md`](standalone-mcp.md).\n", @@ -34,7 +34,7 @@ export const EMBEDDED_DOCS: Readonly> = { "gpt-5.6-codex-preset-benchmark.md": "# GPT-5.6 Codex preset benchmark\n\nThis report records descriptive local exact-edit evidence and the product judgments used to assign GPT-5.6 Sol, Terra, and Luna to GJC's built-in Codex-related model profiles.\n\n## Decision summary\n\nBuilt-in role assignments are product judgments.

Terra xhigh's reported totals were 72% fewer input tokens, 43% fewer output tokens, 28% less estimated list-price cost, and 29% less time than Luna xhigh.

Luna high remains the Eco executor as a product judgment for that preset's lower-priced-family-member trade-off; these local runs do not establish a capability ceiling or production behavior.\n\n### Terra high's product assignment\n\nTerra high recorded 6/11 verified edits after one transport/ghost failure in the selected-task sample. Its planning and lower-stakes critic assignments are product judgments; this edit benchmark does not measure those roles.\n\n### Sol medium's product assignment\n\nSol medium recorded 4/12 verified edits in the selected-task sample and was faster with fewer reported input tokens than the other listed xhigh setups. Its `codex-medium` default-agent assignment and the Sol-family architecture assignments are product judgments because the benchmark does not measure those broader roles.\n\n### Higher effort is not automatically cheaper\n\nThe selected-task data show that Luna xhigh used more reported tokens than Luna high in this local setup. They do not establish a general cost rule for thinking effort; effort selection remains a product decision informed by model tier and role shape.\n\n## Resulting built-in profiles\n\n| Profile | Default | Executor | Planner | Critic | Architect |\n|---|---|---|---|---|---|\n| `codex-eco` | `openai-codex/gpt-5.6-terra:low` | `openai-codex/gpt-5.6-luna:low` | `openai-codex/gpt-5.6-luna:high` | `openai-codex/gpt-5.6-terra:xhigh` | `openai-codex/gpt-5.6-terra:high` |\n| `codex-medium` | `openai-codex/gpt-5.6-sol:low` | `openai-codex/gpt-5.6-terra:low` | `openai-codex/gpt-5.6-terra:high` | `openai-codex/gpt-5.6-sol:xhigh` | `openai-codex/gpt-5.6-sol:high` |\n| `codex-pro` | `openai-codex/gpt-5.6-sol:medium` | `openai-codex/gpt-5.6-terra:medium` | `openai-codex/gpt-5.6-sol:high` | `openai-codex/gpt-5.6-sol:max` | `openai-codex/gpt-5.6-sol:xhigh` |\n| `opus-codex` | `anthropic/claude-opus-4-8:xhigh` | `openai-codex/gpt-5.6-terra:low` | `anthropic/claude-sonnet-5` | `openai-codex/gpt-5.6-sol:xhigh` | `openai-codex/gpt-5.6-sol:high` |\n| `codex-opencodego` | `openai-codex/gpt-5.6-sol:low` | `opencode-go/deepseek-v4-pro` | `opencode-go/kimi-k2.6` | `opencode-go/mimo-v2.5-pro` | `openai-codex/gpt-5.6-sol:high` |\n| `fable-opus-codex` | `anthropic/claude-fable-5:high` | `openai-codex/gpt-5.6-terra:medium` | `anthropic/claude-opus-4-8:medium` | `anthropic/claude-opus-4-8:high` | `openai-codex/gpt-5.6-sol:xhigh` |\n\n## Limitations\n\n- The benchmark measures four selected precise TypeScript source mutations in the repeated sample, not full-session planning, architecture, criticism, or default-agent quality.\n- The corpus is small and intentionally adversarial; the results are descriptive, not statistically significant or a proof of general superiority, production reliability, or stability.\n- Samples used a local OpenAI-compatible provider rather than OpenAI's production endpoint.\n- Terra high has 11 recorded runs because one of 12 scheduled samples ended in a transport/ghost failure.\n- Token accounting reflects the local transport and benchmark context construction.

This document intentionally does not add a bundled provider implementation. It records the product/API decisions that must be accepted before any Grok Build implementation PR should land.\n\nThis is not an authorization claim for xAI endpoints, not a final naming decision, not approval for a bundled-loading exception, and not trademark/display-name approval. Those items require explicit owner sign-off before implementation.\n\n## Required owner sign-off gates\n\nImplementation should remain blocked until the owner signs off on these gates:\n\n1. **Authorized use / ToS** — confirm that GJC may use `cli-chat-proxy.grok.com` and the xAI CLI OAuth public client from a third-party tool. A public OAuth client id is not proof that this use is authorized.\n2. **Bundled-loading trust boundary** — confirm whether a source-controlled bundled provider may load even when ordinary user extension discovery is disabled.\n3. **Public selector naming** — choose the stable provider selector prefix: `grok-cli`, `grok-build`, or another owner-selected id.\n4. **Trademark/display-name** — confirm whether GJC may present the provider/profile using `Grok Build` or should use a more neutral owner-approved label.\n\nIf gate 1 is not accepted, the Grok Build provider implementation should not ship against `cli-chat-proxy.grok.com`. The fallback direction would be a documented user-supplied xAI/API-key provider or a different officially authorized integration path.\n\n## Problem\n\nGJC can load third-party extensions, but the first-run interactive path needs a maintainer-owned decision before a bundled Grok Build provider can be accepted. The desired product flow is:\n\n```text\ngjc -> /login -> OAuth -> Grok Build -> browser xAI login -> /model -> /grok-composer-2.5-fast\n```\n\nThe previously proposed implementation touched bundled extension loading, OAuth registration, model profiles, vendor code, usage reporting, and tests in one PR. That is too much surface for review without first agreeing on the provider contract and the owner sign-off gates above.\n\n## Goals\n\n- Keep Grok Build, if accepted, as a bundled provider extension rather than a workflow skill.\n- Preserve the existing four bundled workflow skills and four role agents.\n- Define the `/login` OAuth contract for an owner-approved display name, with `Grok Build` only as a candidate label.\n- Define the `/model` contract for `grok-composer-2.5-fast` without committing to the final selector prefix before owner sign-off.\n- Define the guardrails for any bundled provider that loads while ordinary extension discovery is disabled.\n- Keep credentials in the existing auth storage path; no tokens or user env values are checked into the repo.\n- Keep implementation PRs small enough for independent review, rejection, or rollback.\n\n## Non-goals\n\n- No new workflow command or `/skill` surface.\n- No automatic installation from npm or remote code at runtime.\n- No direct `packages/ai/src/models.json` edits.\n- No broad model-profile reshuffle.\n- No provider-specific secrets in source.\n- No claim that xAI has authorized this endpoint/client usage without owner review.\n\n## Candidate provider contract\n\nThese are candidate values for owner review, not final commitments:\n\n| Field | Candidate value | Decision status | Notes |\n| --- | --- | --- | --- |\n| Public provider id | `grok-cli` or `grok-build` | **Owner decision required** | See naming section below. |\n| Display name | `Grok Build` or owner-selected label | **Owner decision required** | Name shown in `/login` and UI surfaces; see trademark/display-name section below. |\n| Default model id | `grok-composer-2.5-fast` | Proposed | Full selector depends on final provider id. |\n| Secondary model id | `grok-build` | Proposed | Candidate for executor/architect roles if a profile is accepted. |\n| Base URL | `https://cli-chat-proxy.grok.com/v1` | **Authorized-use sign-off required** | Undocumented/private-looking endpoint; do not ship without owner approval. |\n| OAuth issuer | `https://auth.x.ai` | **Authorized-use sign-off required** | OIDC discovery must validate xAI-owned HTTPS endpoints. |\n| OAuth callback | loopback `127.0.0.1` | Proposed | Uses PKCE + state validation. |\n| API adapter | `grok-cli-responses` | Proposed internal name | Provider-specific stream adapter; not a new generic API shape. |\n| Env bypass | `GROK_CLI_OAUTH_TOKEN` | Optional follow-up | Local bypass only; no refresh or discovery guarantees. |\n\n## Authorized-use and ToS caveat\n\n`cli-chat-proxy.grok.com` and the xAI CLI OAuth public client appear to be designed for xAI/Grok CLI traffic. Reusing them from GJC may be technically possible but still unauthorized or contrary to xAI terms.\n\nBefore implementation, the owner should explicitly decide one of:\n\n- **Accept** — proceed with this integration after reviewing the legal/product risk.\n- **Defer** — keep this design document only; no code ships until authorization is clarified.\n- **Reject** — do not integrate against `cli-chat-proxy.grok.com`; use only an official public API path.\n\nImplementation PRs must not describe the public client id as a secret, but they also must not present it as authorization. Tests should avoid real tokens and should not require an xAI account.\n\n## Trademark/display-name caveat\n\n`Grok` and `xAI` are third-party marks. `Grok Build` may also imply an official xAI/Grok product relationship even when the integration is third-party. Before implementation, the owner should explicitly choose one of:\n\n- **Use `Grok Build`** — acceptable as the user-facing provider/profile label after trademark/product-risk review.\n- **Use a neutral label** — for example `xAI Grok`, `Grok OAuth`, or another owner-selected name that avoids implying official endorsement.\n- **Avoid built-in branding** — keep any Grok-specific naming only in user-provided configuration until authorization/branding is clarified.\n\nImplementation PRs should avoid lock-in language such as \"official\" unless there is explicit authorization. UI labels, profile names, docs, tests, and screenshots must all use the owner-approved label consistently.\n\n## OAuth behavior\n\nIf authorized-use is accepted, the OAuth implementation should use the existing custom OAuth provider path:\n\n1. The chosen provider id registers an OAuth provider using the owner-approved display name.\n2. `/login` calls the existing auth storage login path for that provider.\n3. The provider opens an xAI authorization URL using OIDC discovery, PKCE, `state`, and a loopback callback.\n4. The callback exchanges the authorization code for access and refresh tokens.\n5. Credentials are stored by the existing auth storage code path.\n6. Refresh uses the stored refresh token and validates the token endpoint origin.\n\nSecurity constraints:\n\n- OIDC `authorization_endpoint` and `token_endpoint` must be HTTPS and under owner-approved xAI hosts.\n- The callback server binds to loopback by default.\n- The callback must reject state mismatches.\n- Access and refresh tokens must not be logged, rendered, committed, or included in tests.\n- Error messages may include status and provider error text, but not credential values.\n- Env overrides for base URL, scope, callback host, or client id must be treated as local developer/debug escape hatches, not default product behavior.\n\n## Bundled-loading trust boundary\n\nA bundled provider is different from ordinary user extension discovery, but loading it while `disableExtensionDiscovery: true` still expands the bootstrap trust boundary. Owner sign-off is required before implementation.\n\nMinimum guardrails if accepted:\n\n- Load only source-controlled, maintainer-reviewed bundled provider paths.\n- Use a static allowlist or exported enumerator; never scan arbitrary user directories for this path.\n- Do not install, fetch, or resolve remote package code at runtime.\n- Keep ordinary user extension discovery disabled when `disableExtensionDiscovery: true`; the exception is only for bundled provider defaults.\n- Add tests proving bundled providers load before model selection and caller-supplied `additionalExtensionPaths` still coexist.\n- Keep this bootstrap change separate from the Grok vendor implementation so it can be reviewed independently.\n\nAlternatives the owner may choose:\n\n- Do not load bundled providers when extension discovery is disabled; require explicit setup/defaults install.\n- Gate bundled provider loading behind a setting or compile-time default.\n- Allow bundled loading only in packaged builds, not arbitrary source checkouts.\n\n## Provider selector naming\n\nThe selector prefix is a stable user-facing contract and must be chosen before implementation.\n\n| Option | Example selector | Pros | Cons |\n| --- | --- | --- | --- |\n| `grok-cli` | `grok-cli/grok-composer-2.5-fast` | Matches the upstream CLI/proxy lineage and existing prototype. | User-facing name is less aligned with `Grok Build`; may expose implementation detail. |\n| `grok-build` | `grok-build/grok-composer-2.5-fast` | Matches UI label and requested product wording. | Diverges from existing prototype and env names; migration needed if prototypes used `grok-cli`. |\n| Owner-selected third id | `/grok-composer-2.5-fast` | Lets maintainers align with broader provider taxonomy. | Requires updating all docs/tests before implementation. |\n\nUntil this is decided, implementation docs and PRs should use `` when describing the public selector. Internal adapter names may still use `grok-cli-responses` if maintainers accept that as an implementation detail.\n\n## Model/profile behavior\n\nModel registration should be provider-owned. If accepted, the provider should register at least:\n\n- `grok-composer-2.5-fast`\n- `grok-build`\n\nA built-in profile is optional and should be reviewed separately. If accepted, a candidate profile is:\n\n```text\ngrok-pro.default -> /grok-composer-2.5-fast\ngrok-pro.planner -> /grok-composer-2.5-fast\ngrok-pro.critic -> /grok-composer-2.5-fast\ngrok-pro.executor -> /grok-build\ngrok-pro.architect -> /grok-build\n```\n\nIf maintainers prefer not to add a built-in profile, the provider can still satisfy the core `/login` and `/model` flow through direct model selection.\n\n## Usage reporting behavior\n\nUsage reporting should be an optional follow-up after login/model support lands:\n\n- Provider id: the owner-selected ``.\n- Fetches usage with the effective OAuth access token.\n- Returns `null` when no token is available.\n- Does not require the usage provider for chat/model selection to work.\n- Should be skipped entirely if the authorized-use gate is not accepted.\n\n## Staged PR plan\n\n### PR 1: this design document\n\nPurpose: agree on caveats, owner sign-off gates, provider id, OAuth contract, bundled-loading trust boundary, model selector, security boundaries, and implementation split.\n\n### PR 2: bundled provider bootstrap contract\n\nSmall core change only, after owner sign-off on the bundled-loading gate:\n\n- Add a maintainer-owned way to enumerate bundled provider extension paths.\n- Load those paths during session/bootstrap only under the accepted guardrails.\n- Add tests proving bundled providers and caller-supplied extension paths coexist.\n\nNo Grok vendor implementation in this PR.\n\n### PR 3: Grok Build provider extension\n\nProvider implementation only, after owner sign-off on authorized use, public selector naming, and trademark/display-name:\n\n- Add bundled Grok Build provider source.\n- Register the chosen provider id, OAuth provider, and models.\n- Include sanitize and provider-specific stream handling.\n- Test `/login` provider registration and `grok-composer-2.5-fast` model availability.\n\n### PR 4: profile and model defaults\n\nOptional product-surface PR:\n\n- Add `grok-pro` only if maintainers accept a built-in profile.\n- Add model profile catalog tests.\n\n### PR 5: usage reporting\n\nOptional observability PR:\n\n- Add usage provider for the owner-selected provider id.\n- Add focused usage tests.\n\n## Acceptance criteria for the implementation series\n\n- Owner sign-off is recorded for authorized use, bundled loading, selector naming, and trademark/display-name before implementation lands.\n- Fresh checkout test proves `createAgentSession` registers the bundled provider under the accepted bootstrap rules.\n- `/login` includes the owner-approved display name for the owner-selected provider id.\n- `/model` includes `/grok-composer-2.5-fast`.\n- A real OAuth URL redirects to the owner-approved xAI account login page.\n- Third-party extension paths still load alongside bundled providers when configured.\n- Token values never appear in tests, logs, checked-in docs, or git history.\n\n## Open maintainer decisions\n\n- Is using `cli-chat-proxy.grok.com` plus the xAI CLI OAuth client from GJC authorized and acceptable for this project?\n- Should bundled provider defaults load while `disableExtensionDiscovery: true`, and under which guardrails?\n- Should the final public provider id be `grok-cli`, `grok-build`, or another id?\n- May GJC use `Grok Build` as the display/profile name, or should the integration use a neutral owner-selected label?\n- Should `grok-pro` be a built-in profile or documented as a user profile?\n- Should usage reporting be included in the initial provider PR or kept as a separate follow-up?", "handoff-generation-pipeline.md": "# `/handoff` generation pipeline\n\nThis document describes how the coding-agent implements `/handoff`: trigger path, oneshot generation, session switch, context reinjection, persistence, and UI behavior.\n\n## Scope\n\nCovers:\n\n- Interactive `/handoff` command dispatch\n- `AgentSession.handoff()` lifecycle and state transitions\n- `generateHandoff(...)` request shape\n- How old/new sessions persist handoff data differently\n- UI behavior for success, cancel, and failure\n\nDoes not cover:\n\n- Generic tree navigation/branch internals\n- Non-handoff session commands (`/new`, `/fork`, `/resume`)\n\n## Implementation files\n\n- [`../src/modes/controllers/input-controller.ts`](../packages/coding-agent/src/modes/controllers/input-controller.ts)\n- [`../src/modes/controllers/command-controller.ts`](../packages/coding-agent/src/modes/controllers/command-controller.ts)\n- [`../src/session/agent-session.ts`](../packages/coding-agent/src/session/agent-session.ts)\n- [`packages/agent/src/compaction/compaction.ts`](../packages/agent/src/compaction/compaction.ts)\n- [`../src/session/session-manager.ts`](../packages/coding-agent/src/session/session-manager.ts)\n- [`../src/extensibility/slash-commands.ts`](../packages/coding-agent/src/extensibility/slash-commands.ts)\n\n## Trigger path\n\n1. `/handoff` is declared in builtin slash command metadata (`slash-commands.ts`) with optional inline hint: `[focus instructions]`.\n2. In interactive input handling (`InputController`), submit text matching `/handoff` or `/handoff ...` is intercepted before normal prompt submission.\n3. The editor is cleared and `handleHandoffCommand(customInstructions?)` is called.\n4. `CommandController.handleHandoffCommand` performs a preflight guard using current entries:\n - Counts `type === \"message\"` entries.\n - If `< 2`, it warns: `Nothing to hand off (no messages yet)` and returns.\n\nThe same minimum-content guard exists again inside `AgentSession.handoff()` and throws if violated. This duplicates safety at both UI and session layers.\n\n## End-to-end lifecycle\n\n### 1) Start handoff generation\n\n`AgentSession.handoff(customInstructions?)`:\n\n- Reads current branch entries (`sessionManager.getBranch()`).\n- Validates minimum message count (`>= 2`).\n- Creates `#handoffAbortController` and links any caller-provided abort signal to it.\n- Resolves the current model API key through `ModelRegistry`.\n- Calls `generateHandoff(...)` with:\n - live agent messages (`agent.state.messages`),\n - the current model and API key,\n - the base system prompt (`#baseSystemPrompt`),\n - the live tool array (`agent.state.tools`),\n - optional focus instructions,\n - coding-agent message conversion (`convertToLlm`),\n - provider metadata and `initiatorOverride: \"agent\"`.\n\n`generateHandoff(...)` lives in `packages/agent/src/compaction/compaction.ts` next to summarization. It renders `packages/agent/src/compaction/prompts/handoff-document.md` via `renderHandoffPrompt(...)` with optional `additionalFocus`.\n\n### 2) Generate and capture output\n\n`generateHandoff(...)` converts the existing `AgentMessage[]` history to real LLM `Message[]` history, then appends one trailing agent-attributed `user` message containing the rendered handoff prompt.\n\nThe request uses `completeSimple(...)` directly:\n\n```ts\nawait completeSimple(\n model,\n {\n systemPrompt,\n messages: requestMessages,\n tools,\n },\n {\n apiKey,\n signal,\n reasoning: Effort.High,\n toolChoice: \"none\",\n initiatorOverride,\n metadata,\n },\n);\n```\n\nImportant generation properties:\n\n- The request preserves the live provider cache prefix by reusing the same system prompt, tool definitions, and real message history shape as the active agent.\n- The handoff instruction is a trailing `user` message, not a developer message, so the cached prefix remains aligned with the prior turn.\n- `toolChoice: \"none\"` prevents intentional tool dispatch.\n- The returned assistant content is filtered to text blocks and joined with `\\n`; stray tool-call blocks are ignored if a provider does not honor `toolChoice: \"none\"`.\n- `stopReason === \"error\"` throws a generation error.\n\nNo agent-loop events are used for capture. The handoff path no longer waits for `agent_end` and no longer scans the latest assistant message.\n\n### 3) Cancellation checks\n\nCancellation throws `Error(\"Handoff cancelled\")`; a completed generation with no text returns `undefined`.\n\n- caller signal aborts `#handoffAbortController`\n- `completeSimple(...)` receives the abort signal\n- aborted handoff signal or provider `AbortError` is normalized to `Error(\"Handoff cancelled\")`\n- empty generated text returns `undefined`\n\n`AgentSession.handoff()` always clears `#handoffAbortController` in `finally`.\n\n### 4) New session creation\n\nIf text was generated and not aborted:\n\n1. Flush current session writer (`sessionManager.flush()`).\n2. Cancel session-owned async jobs.\n3. Start a brand-new session with `parentSession` pointing at the previous session file when one exists.\n4. Reset in-memory agent state (`agent.reset()`).\n5. Rebind `agent.sessionId` to the new session id.\n6. Rekey/reset hindsight state for the new session.\n7. Clear queued context arrays (`#steeringMessages`, `#followUpMessages`, `#pendingNextTurnMessages`) and any scheduled hidden next-turn generation.\n8. Reset todo reminder counter.\n\n### 5) Handoff-context injection\n\nThe generated handoff document is wrapped by coding-agent session glue and appended to the new session as a `custom_message` entry:\n\n```text\n\n...handoff text...\n\n\nThe above is a handoff document from a previous session. Use this context to continue the work seamlessly.\n```\n\nInsertion call:\n\n```ts\nthis.sessionManager.appendCustomMessageEntry(\"handoff\", handoffContent, true, undefined, \"agent\");\n```\n\nSemantics:\n\n- `customType`: `\"handoff\"`\n- `display`: `true` (visible in TUI rebuild)\n- attribution: `\"agent\"`\n- Entry type: `custom_message` (participates in LLM context)\n\n### 6) Rebuild active agent context\n\nAfter injection:\n\n1. `buildDisplaySessionContext()` resolves message list for current leaf.\n2. `agent.replaceMessages(sessionContext.messages)` makes the injected handoff message active context.\n3. Todo phases are synchronized from the new branch.\n4. Method returns `{ document: handoffText, savedPath? }`.\n\nAt this point, the active LLM context in the new session contains the injected handoff message, not the old transcript.\n\n## Persistence model: old session vs new session\n\n### Old session\n\nHandoff generation is a oneshot request, not a visible agent turn. The generated handoff text is not appended to the old session as an assistant message.\n\nResult: the original session keeps its prior transcript unchanged except for data already persisted before handoff began.\n\n### New session\n\nAfter session reset, handoff is persisted as `custom_message` with `customType: \"handoff\"`.\n\n`buildSessionContext()` converts this entry into a runtime custom/user-context message via `createCustomMessage(...)`, so it is included in future prompts from the new session.\n\nAuto-triggered handoffs can additionally write a timestamped `handoff-*.md` artifact under the session artifacts directory when `compaction.handoffSaveToDisk` is enabled. Manual `/handoff` does not write that artifact.\n\n## Controller/UI behavior\n\n`CommandController.handleHandoffCommand` behavior:\n\n- Shows a status loader: `Generating handoff… (esc to cancel)`.\n- Calls `await session.handoff(customInstructions)`.\n- If result is `undefined`: `showError(\"Handoff cancelled\")`.\n- On success:\n - `rebuildChatFromMessages()` (loads new session context, including injected handoff)\n - invalidates status line and editor top border\n - reloads todos\n - appends success chat line: `New session started with handoff context`\n- On exception:\n - if message is `\"Handoff cancelled\"` or error name is `AbortError`: `showError(\"Handoff cancelled\")`\n - otherwise: `showError(\"Handoff failed: \")`\n- Stops the loader, restores the previous Escape handler, and requests render at end.\n\nManual `/handoff` no longer streams the generated document into chat. A cancellable loader remains visible while the oneshot request runs, and the chat is rebuilt after generation completes.\n\n## Cancellation semantics\n\n### Session-level cancellation primitive\n\n`AgentSession` exposes:\n\n- `abortHandoff()` → aborts `#handoffAbortController`\n- `isGeneratingHandoff` → true while controller exists\n\nWhen this abort path is used, the abort signal is passed to `completeSimple(...)`; `handoff()` normalizes the cancellation to `Error(\"Handoff cancelled\")`, and command controller maps it to cancellation UI.\n\n### Interactive `/handoff` path\n\nThe command controller installs a temporary Escape handler for `/handoff` while the loader is visible. Pressing Escape calls `session.abortHandoff()`, which aborts the `completeSimple(...)` request through `#handoffAbortController`.\n\n## Aborted vs failed handoff\n\nCurrent UI classification:\n\n- **Aborted/cancelled**\n - `abortHandoff()` path triggers `\"Handoff cancelled\"`, or\n - thrown `AbortError`\n - UI shows `Handoff cancelled`\n- **Failed**\n - any other thrown error from `handoff()` / `generateHandoff()` / provider request path\n - UI shows `Handoff failed: ...`\n\nAdditional nuance: if generation completes but no text is returned, `handoff()` returns `undefined` and controller currently reports **cancelled**, not **failed**.\n\n## Short-session and minimum-content guardrails\n\nTwo guards prevent low-signal handoffs:\n\n- UI layer (`handleHandoffCommand`): warns and returns early for `< 2` message entries\n- Session layer (`handoff()`): throws the same condition as an error\n\nThis avoids creating a new session with empty/near-empty handoff context.\n\n## State transition summary\n\nHigh-level state flow:\n\n1. Interactive slash command intercepted.\n2. Preflight message-count guard.\n3. `#handoffAbortController` created (`isGeneratingHandoff = true`).\n4. `generateHandoff(...)` issues one `completeSimple(...)` request with live system prompt, tools, message history, and trailing handoff prompt.\n5. Assistant response text blocks are joined; tool-call blocks are discarded.\n6. If missing text → return `undefined`; if aborted → cancellation error path.\n7. If present:\n - flush old session\n - cancel async jobs\n - create new empty session with previous session as parent\n - reset runtime queues/counters\n - append `custom_message(handoff)`\n - optionally save an auto-triggered handoff document under the session artifacts directory when `compaction.handoffSaveToDisk` is enabled\n8. Controller rebuilds chat UI and announces success.\n9. `#handoffAbortController` cleared (`isGeneratingHandoff = false`).\n\n## Known assumptions and limitations\n\n- No structural validation checks that generated markdown follows the requested section format.\n- Missing generated text is reported as cancellation in controller UX.\n- Manual handoff has no streaming visibility; a cancellable loader is shown until the UI updates after generation completes.\n- Auto-triggered handoffs can write a timestamped `handoff-*.md` artifact when `compaction.handoffSaveToDisk` is enabled; write failure is logged and does not fail the handoff.\n", - "hermes-mcp-bridge.md": "# Coordinator MCP bridge\n\nGJC exposes a native outward MCP bridge for external coordinators:\n\n```bash\ngjc mcp-serve coordinator\n```\n\n`gjc mcp-serve hermes` is accepted as a compatibility alias for the same coordinator bridge.\n\nThe bridge is intentionally separate from GJC's client-side MCP runtime. It lets an external coordinator discover and control SDK-backed sessions, queue bounded follow-up prompts, read status/artifacts, handle structured questions, and write coordination reports without scraping terminal scrollback.\n\n## Core contract and adapters\n\nThe coordinator bridge is intentionally a core contract with multiple adapters, not an MCP-only or Hermes-only product direction. Hermes is one compatibility preset, not a privileged integration mode:\n\n- `packages/coding-agent/src/coordinator/contract.ts` owns transport-neutral server metadata and tool names.\n- `gjc mcp-serve coordinator` is the outward MCP adapter for external agents.\n- `gjc coordinator` is the read-only CLI/debug adapter for humans and scripts that need to inspect the same contract without starting MCP transport.\n- `gjc setup hermes` is the compatibility setup adapter that renders coordinator config and operator guidance.\n\nFuture session, turn, question, artifact, and report behavior should move toward shared coordinator core services that both MCP and CLI adapters call instead of duplicating transport-specific logic.\n\n## Coordinator setup adapter\n\nUse `gjc setup hermes` to render or install a portable MCP setup package for any controller that accepts Hermes-compatible MCP config:\n\n```bash\ngjc setup hermes --root /path/to/repo --profile my-bot --repo gajae-code\n```\n\nThe default mode is render-only and writes no files. To install into a Hermes profile:\n\n```bash\ngjc setup hermes \\\n --root /path/to/repo \\\n --profile my-bot \\\n --repo gajae-code \\\n --mutation sessions,questions,reports \\\n --profile-dir /path/to/hermes/profile \\\n --install\n```\n\nThe generated setup is model-agnostic and worktree-isolated. By default it renders `GJC_COORDINATOR_MCP_SESSION_COMMAND` as `gjc --worktree`, which is a typed selector for SDK lifecycle creation—not a shell command the bridge runs. Spawned sessions launch inside a GJC-managed sibling worktree while GJC retains the source repository as project identity. Users who need a stable named branch can set `--worktree-name`:\n\n```bash\ngjc setup hermes \\\n --root /path/to/repo \\\n --worktree-name hermes-gajae-code\n```\n\nThe runtime accepts only the literal selectors `gjc` and `gjc --worktree [name]`. It rejects local wrappers, shell syntax, tmux flags, and model/provider flags before creating a session. Existing setup configs that contain a legacy explicit `--session-command` must be changed to one of those selectors; provider and model resolution remains normal GJC configuration, not coordinator command injection.\n\nRun a non-mutating setup smoke check with:\n\n```bash\ngjc setup hermes --root /path/to/repo --smoke\n```\n\nSmoke verifies the MCP server/tool contract. It does not call a downstream LLM and does not validate provider credentials.\n\n\n## Safety model\n\nThe bridge is read-only and fail-closed by default.\n\nRequired root allowlist:\n\n```bash\nexport GJC_COORDINATOR_MCP_WORKDIR_ROOTS=\"/path/to/repo:/path/to/worktrees\"\n```\n\nMutating tools require both startup opt-in and per-call consent:\n\n```bash\nexport GJC_COORDINATOR_MCP_MUTATIONS=\"sessions,questions,reports\"\n```\n\nEvery mutating MCP call that requires a caller key must include `allow_mutation: true` and the required caller-provided `idempotency_key`. The bridge durably binds the key to the tool and canonical arguments, serializes concurrent duplicates, replays the original bounded public response, and rejects reuse with different arguments as `idempotency_conflict`.\n\n`gjc_coordinator_start_session` uses SDK lifecycle control with the configured typed GJC selector. `gjc setup hermes` writes `gjc --worktree` by default:\n\n```bash\nexport GJC_COORDINATOR_MCP_SESSION_COMMAND=\"gjc --worktree\"\n```\n\nThe only supported values are `gjc` and `gjc --worktree [name]`; this variable is never evaluated as a shell command. The coordinator binds registration, reuse, and control to the broker's exact canonical workspace and endpoint generation, then discovers the generation-bound SDK endpoint internally. Endpoint credentials are never persisted in coordinator records or returned by coordinator tools. `gjc_coordinator_read_coordination_status` returns a canonical polling snapshot for public session, state, turn, question, report, and bounded event data. Tmux identifiers, when supplied while registering an existing session, are advisory process metadata only; they do not provide control authority, machine viewing, startup, prompt injection, or determine turn completion.\n\nFor resume safety, prefer the generated GJC-native worktree selector over creating a git worktree in Hermes itself. GJC's launch path records the original repo as the project identity while running in the worktree, so session listing/resume can still group the session under the source project. If Hermes creates and later deletes an unmanaged worktree, a saved session may still exist but its cwd can be gone.\n\nArtifact reads are canonicalized, symlink escapes are rejected, and returned content is byte-capped by `GJC_COORDINATOR_MCP_ARTIFACT_BYTE_CAP`.\n\n`gjc setup hermes` renders `GJC_COORDINATOR_MCP_WORKDIR_ROOTS` with the host platform path delimiter (`:` on POSIX, `;` on Windows). Manual configs should prefer the same encoding.\n\n## Optional namespace\n\nUse namespace variables to prevent cross-profile or cross-repo enumeration:\n\n```bash\nexport GJC_COORDINATOR_MCP_PROFILE=\"team-a\"\nexport GJC_COORDINATOR_MCP_REPO=\"gajae-code\"\n```\n\nMissing namespace never widens into global session enumeration.\n\n## Tool surface\n\nRead tools:\n\n- `gjc_coordinator_list_sessions`\n- `gjc_coordinator_read_status`\n- `gjc_coordinator_read_tail`\n- `gjc_coordinator_list_questions`\n- `gjc_coordinator_list_artifacts`\n- `gjc_coordinator_read_artifact`\n- `gjc_coordinator_read_coordination_status`\n- `gjc_coordinator_read_turn`\n- `gjc_coordinator_await_turn`\n- `gjc_coordinator_watch_events`\n\n\nMutating tools:\n\n- `gjc_coordinator_start_session`\n- `gjc_coordinator_register_session`\n- `gjc_coordinator_send_prompt`\n- `gjc_coordinator_submit_question_answer`\n- `gjc_coordinator_report_status`\n- `gjc_delegate_plan`\n- `gjc_delegate_execute`\n- `gjc_delegate_team`\n\nThe `gjc_delegate_*` tools are high-level, session-level delegation: each starts (or reuses) an SDK-discovered session and sends one workflow-tagged turn for `/skill:ralplan`, `/skill:ultragoal`, or `/skill:team`, returning a durable `turn_id`, status, and artifact references. They use the same `sessions` mutation class and fail-closed workdir gating as `gjc_coordinator_start_session`, and emit a `delegation.started` event. Pass `await_completion: true` to use the durable bounded await/report path; `timeout_ms` and `poll_interval_ms` apply to that completion payload. Without it, the tool returns immediately after SDK acknowledgement. Pass `cwd` and `task`; set `allow_mutation: true` and a caller-provided `idempotency_key` only with startup mutation opt-in plus per-call consent. Optionally pass `mpreset` (same semantics as `gjc --mpreset `) to `gjc_coordinator_start_session` or a delegate tool to authoritatively activate a GJC model profile when starting a fresh session — it is resolved through the merged built-in/custom profile registry, applied from the first turn, and surfaced in status; unknown names are rejected with the available-profile listing, and reusing a session with a conflicting `mpreset` fails with `mpreset_conflict`. This is distinct from the advisory `model` prompt hint. Prefer these over manual `start_session` + `send_prompt` when delegating a whole workflow.\n\n`gjc_coordinator_register_session` registers an existing SDK-discoverable GJC session for coordinator control. It validates the workdir allowlist and session id, then verifies the broker's exact canonical workspace and endpoint generation before writing a credential-free session record. Optional tmux identifiers are retained only as advisory process metadata and are never machine-read.\n## Turn orchestration flow\n\nExternal coordinators should treat turns, not terminal scrollback, as the unit of work:\n\n1. Call `gjc_coordinator_start_session` with `allow_mutation: true` and `idempotency_key`.\n2. Call `gjc_coordinator_send_prompt` with `allow_mutation: true` and `idempotency_key`.\n3. Store the returned `turn_id`.\n4. Poll `gjc_coordinator_read_turn`, or call bounded `gjc_coordinator_await_turn`, until the turn is terminal.\n5. Pull `gjc_coordinator_list_questions` with the required `session_id`; it reconciles pending `workflow.gates.list` rows and returns bounded questions, diagnostics, and reconciliation state. Submit each pending row with `gjc_coordinator_submit_question_answer`.\n\n6. Use `gjc_coordinator_report_status` with `session_id` and `turn_id` to write explicit completion/failure evidence.\n Use `status: \"cancelled\"` for coordinator-policy cancellation, and `status: \"failed\"` plus `blocker` for provider/tool/task failures.\n\n`gjc_coordinator_send_prompt` returns versioned top-level routing fields that exactly mirror its nested durable `turn`: `status`, `queued`, and `delivered` equal `turn.status`, `turn.delivery.queued`, and `turn.delivery.delivered`; `active_turn_id` is the new turn id unless this response queued a follow-up, in which case it is the existing active turn id.\n\n```json\n{\n \"ok\": true,\n \"session_id\": \"gjc-coordinator-demo\",\n \"turn_id\": \"turn-00000000-0000-0000-0000-000000000000\",\n \"active_turn_id\": \"turn-00000000-0000-0000-0000-000000000000\",\n \"status\": \"active\",\n \"queued\": false,\n \"delivered\": true\n}\n```\n\nA session may have only one active turn by default. A second prompt is rejected with `active_turn_exists` unless the caller explicitly passes `queue: true` or `force: true`. Queued turns are durable and the next queued turn is promoted when the active turn reaches a terminal `gjc_coordinator_report_status`. Force supersedes the previous active turn and audits that state in the turn journal.\nCoordinator cancellation is recorded through `gjc_coordinator_report_status` with terminal `status: \"cancelled\"`; this updates durable turn state but does not control any process. If the correct policy is replacement work rather than cancellation, send the replacement prompt with `force: true` so the previous active turn is superseded and audited.\n\n`gjc_coordinator_read_turn` returns the authoritative durable turn and SDK-only advisory status. For the latest assistant output, use `gjc_coordinator_read_tail`; it queries `session.last_assistant` through the session SDK and returns only the requested bounded line suffix, never terminal output.\n\n```json\n{\n \"ok\": true,\n \"turn\": {\n \"schema_version\": 1,\n \"turn_id\": \"turn-00000000-0000-0000-0000-000000000000\",\n \"session_id\": \"gjc-coordinator-demo\",\n \"status\": \"completed\",\n \"final_response\": {\n \"text\": \"Done\",\n \"format\": \"markdown\",\n \"source\": \"report_status\",\n \"artifact_path\": null,\n \"truncated\": false\n },\n \"evidence\": [{ \"path\": \"artifact.txt\" }],\n \"error\": null\n },\n \"advisory_status\": {\n \"authority\": \"sdk\",\n \"live\": true,\n \"is_streaming\": false\n }\n}\n```\n\nThe coordinator MCP bridge is currently a durable polling/await surface. It does not expose a push subscription stream; external coordinators should poll `gjc_coordinator_read_coordination_status`, `gjc_coordinator_read_turn`, or bounded `gjc_coordinator_await_turn` instead of waiting for server-sent push events.\n\nExternal `session_id`, `turn_id`, and `question_id` values are validated before path use, and loaded records must match the requested session/turn owner.\n\n### Coordinator question pull loop\n\n`gjc_coordinator_list_questions` requires `session_id` and reconciles the session's pending `workflow.gates.list` rows on every call. Its bounded response contains public `questions`, `diagnostics`, and `reconciliation`; `status: \"pending\"` selects pending rows, while `status: \"open\"` remains a compatibility alias. More than one pending question may be returned. Public rows expose only the safe question shape, public option ids, and a fresh `answer_binding` for each pending row—never raw/private gate payloads or values.\n\n`gjc_coordinator_submit_question_answer` requires `session_id`, `turn_id`, `question_id`, `answer_binding`, `answer`, `idempotency_key`, and `allow_mutation: true`. Copy the identifiers and binding from the pending row and use the advertised answer shape. The bridge re-reconciles and revalidates ownership, pending state, and the binding before calling `workflow.gate_answer`; it never invokes generic `ask.answer`. An incomplete snapshot fails as `terminal_uncertain`; stale, terminal, missing, or ownership-mismatched rows are non-answerable. Restart can remint or quarantine gates, so re-list instead of reusing old rows. Identical idempotent replay returns the original accepted result; the same key with different arguments fails `idempotency_conflict`.\n\nThis pull-loop contract is independent of #2549/#2551 and unattended plain-CLI handling.\n\n## Coordinator event journal\n\nThe bridge persists a restart-safe event journal under the configured coordinator state namespace, for example:\n\n```text\n$GJC_COORDINATOR_MCP_STATE_ROOT///events/event-journal.jsonl\n```\n\nEach event is a bounded JSONL record with `schema_version`, monotonic namespace-local `seq`, stable `id`, `timestamp`, canonical `kind`, optional `session_id`/`turn_id`/`question_id`/`report_id`, short `summary`, optional `payload_ref`, and bounded scalar `metadata`. Full prompts, reports, final responses, and artifacts stay in their existing turn/report/artifact read paths; event records only point at them.\n\n`gjc_coordinator_watch_events` is a bounded long-poll MCP tool, not an unbounded stream. Inputs are `after_seq` (default `0`), optional `session_id`, optional `event_types`, `timeout_ms` capped at 30000, and `limit` capped at 100. If matching events already exist after `after_seq`, it returns immediately. Otherwise it waits for the event journal to change or for timeout. The response includes `events`, `latest_seq`, `timed_out`, and `transport: { \"mcp\": \"long_poll\", \"push_subscriptions\": false }`, so coordinators can persist `latest_seq` and resume safely after restart.\n\n`gjc_coordinator_read_coordination_status` keeps its existing report fields and now also includes `latest_event_seq` plus recent event summaries for snapshot-style consumers.\n\n## Generic controller config snippet\n\n```json\n{\n \"mcp_servers\": {\n \"gjc_coordinator\": {\n \"command\": \"gjc\",\n \"args\": [\"mcp-serve\", \"coordinator\"],\n \"env\": {\n \"GJC_COORDINATOR_MCP_WORKDIR_ROOTS\": \"/path/to/repo\",\n \"GJC_COORDINATOR_MCP_PROFILE\": \"team-a\",\n \"GJC_COORDINATOR_MCP_REPO\": \"project\",\n \"GJC_COORDINATOR_MCP_SESSION_COMMAND\": \"gjc --worktree\"\n },\n \"enabled\": true\n }\n }\n}\n```\n\n## Smoke check\n\n```bash\ngjc mcp-serve coordinator --check --json\n```\n\nExpected result includes `ok: true`, server name `gjc-coordinator-mcp`, and the GJC-named tool list. The JSON check is discovery-only and non-mutating: it retains those legacy fields and adds `catalog: { \"ready\": true, \"reason\": null }` and `broker`. `broker.discovery_status` is `ready`, `unavailable`, or `error`, with reason `null`, `absent_or_invalid`, `unsupported_state_version`, `discovery_access_denied`, or `discovery_read_failed`. `broker.operational_ready` is always `null`; the check does not connect, ensure/bootstrap, write, repair, or delete. `bootstrap_supported` is `true` and `bootstrap_attempted` is `false`. It does not expose broker authority, path, endpoint, process metadata, token, or raw error details. `gjc mcp-serve hermes --check --json` returns the identical coordinator check payload; its human output remains the server/tools summary.\n", + "hermes-mcp-bridge.md": "# Coordinator MCP bridge\n\nGJC exposes a native outward MCP bridge for external coordinators:\n\n```bash\ngjc mcp-serve coordinator\n```\n\n`gjc mcp-serve hermes` is accepted as a compatibility alias for the same coordinator bridge.\n\nThe bridge is intentionally separate from GJC's client-side MCP runtime. It lets an external coordinator discover and control SDK-backed sessions, queue bounded follow-up prompts, read status/artifacts, handle structured questions, and write coordination reports without scraping terminal scrollback.\n\n## Core contract and adapters\n\nThe coordinator bridge is intentionally a core contract with multiple adapters, not an MCP-only or Hermes-only product direction. Hermes is one compatibility preset, not a privileged integration mode:\n\n- `packages/coding-agent/src/coordinator/contract.ts` owns transport-neutral server metadata and tool names.\n- `gjc mcp-serve coordinator` is the outward MCP adapter for external agents.\n- `gjc coordinator` is the read-only CLI/debug adapter for humans and scripts that need to inspect the same contract without starting MCP transport.\n- `gjc setup hermes` is the compatibility setup adapter that renders coordinator config and operator guidance.\n\nFuture session, turn, question, artifact, and report behavior should move toward shared coordinator core services that both MCP and CLI adapters call instead of duplicating transport-specific logic.\n\n## Coordinator setup adapter\n\nUse `gjc setup hermes` to render or install a portable MCP setup package for any controller that accepts Hermes-compatible MCP config:\n\n```bash\ngjc setup hermes --root /path/to/repo --profile my-bot --repo gajae-code\n```\n\nThe default mode is render-only and writes no files. To install into a Hermes profile:\n\n```bash\ngjc setup hermes \\\n --root /path/to/repo \\\n --profile my-bot \\\n --repo gajae-code \\\n --mutation sessions,questions,reports \\\n --profile-dir /path/to/hermes/profile \\\n --install\n```\n\nThe generated setup is model-agnostic and worktree-isolated. By default it renders `GJC_COORDINATOR_MCP_SESSION_COMMAND` as `gjc --worktree`, which is a typed selector for SDK lifecycle creation—not a shell command the bridge runs. Spawned sessions launch inside a GJC-managed sibling worktree while GJC retains the source repository as project identity. Users who need a stable named branch can set `--worktree-name`:\n\n```bash\ngjc setup hermes \\\n --root /path/to/repo \\\n --worktree-name hermes-gajae-code\n```\n\nThe runtime accepts only the literal selectors `gjc` and `gjc --worktree [name]`. It rejects local wrappers, shell syntax, tmux flags, and model/provider flags before creating a session. Existing setup configs that contain a legacy explicit `--session-command` must be changed to one of those selectors; provider and model resolution remains normal GJC configuration, not coordinator command injection.\n\nRun a non-mutating setup smoke check with:\n\n```bash\ngjc setup hermes --root /path/to/repo --smoke\n```\n\nSmoke verifies the MCP server/tool contract. It does not call a downstream LLM and does not validate provider credentials.\n\n\n## Safety model\n\nThe bridge is read-only and fail-closed by default.\n\nRequired root allowlist:\n\n```bash\nexport GJC_COORDINATOR_MCP_WORKDIR_ROOTS=\"/path/to/repo:/path/to/worktrees\"\n```\n\nMutating tools require both startup opt-in and per-call consent:\n\n```bash\nexport GJC_COORDINATOR_MCP_MUTATIONS=\"sessions,questions,reports\"\n```\n\nEvery mutating MCP call that requires a caller key must include `allow_mutation: true` and the required caller-provided `idempotency_key`. The bridge durably binds the key to the tool and canonical arguments, serializes concurrent duplicates, replays the original bounded public response, and rejects reuse with different arguments as `idempotency_conflict`.\n\n`gjc_coordinator_start_session` uses SDK lifecycle control with the configured typed GJC selector. `gjc setup hermes` writes `gjc --worktree` by default:\n\n```bash\nexport GJC_COORDINATOR_MCP_SESSION_COMMAND=\"gjc --worktree\"\n```\n\nThe only supported values are `gjc` and `gjc --worktree [name]`; this variable is never evaluated as a shell command. The coordinator binds registration, reuse, and control to the broker's exact canonical workspace and endpoint generation, then discovers the generation-bound SDK endpoint internally. Endpoint credentials are never persisted in coordinator records or returned by coordinator tools. `gjc_coordinator_read_coordination_status` returns a canonical polling snapshot for public session, state, turn, question, report, and bounded event data. Tmux identifiers, when supplied while registering an existing session, are advisory process metadata only; they do not provide control authority, machine viewing, startup, prompt injection, or determine turn completion.\n\nFor resume safety, prefer the generated GJC-native worktree selector over creating a git worktree in Hermes itself. GJC's launch path records the original repo as the project identity while running in the worktree, so session listing/resume can still group the session under the source project. If Hermes creates and later deletes an unmanaged worktree, a saved session may still exist but its cwd can be gone.\n\nArtifact reads are canonicalized, symlink escapes are rejected, and returned content is byte-capped by `GJC_COORDINATOR_MCP_ARTIFACT_BYTE_CAP`.\n\n`gjc setup hermes` renders `GJC_COORDINATOR_MCP_WORKDIR_ROOTS` with the host platform path delimiter (`:` on POSIX, `;` on Windows). Manual configs should prefer the same encoding.\n\n## Optional namespace\n\nUse namespace variables to prevent cross-profile or cross-repo enumeration:\n\n```bash\nexport GJC_COORDINATOR_MCP_PROFILE=\"team-a\"\nexport GJC_COORDINATOR_MCP_REPO=\"gajae-code\"\n```\n\nMissing namespace never widens into global session enumeration.\n\n## Tool surface\n\nRead tools:\n\n- `gjc_coordinator_list_sessions`\n- `gjc_coordinator_read_status`\n- `gjc_coordinator_read_tail`\n- `gjc_coordinator_list_questions`\n- `gjc_coordinator_list_artifacts`\n- `gjc_coordinator_read_artifact`\n- `gjc_coordinator_read_coordination_status`\n- `gjc_coordinator_read_turn`\n- `gjc_coordinator_await_turn`\n- `gjc_coordinator_watch_events`\n- `gjc_coordinator_read_codex_handoff` — reads the Codex app-server resume bridge registration and durable wake state; endpoints are unix sockets or loopback TCP only, and token-file references only. Returned wake events expose lifecycle schema version 1 (`pending` → `requested`, `published` → `delivered`, `acked` → `acknowledged`, `failed` → `failed`); durable `attempts` and `last_error` are its failure/retry metadata. Heartbeats are unsupported (`automation_update_unavailable`), so delivery remains event-driven with startup drain.\n\n\nMutating tools:\n\n- `gjc_coordinator_start_session`\n- `gjc_coordinator_register_session`\n- `gjc_coordinator_send_prompt`\n- `gjc_coordinator_submit_question_answer`\n- `gjc_coordinator_report_status`\n- `gjc_coordinator_register_codex_handoff` — registers the Codex app-server resume bridge with a unix/loopback endpoint and token-file reference only.\n- `gjc_coordinator_ack_codex_handoff` — acknowledges a Codex resume wake by durable `wake_key`; wake prompts never include GJC final responses.\n- `gjc_delegate_plan`\n- `gjc_delegate_execute`\n- `gjc_delegate_team`\n\nThe `gjc_delegate_*` tools are high-level, session-level delegation: each starts (or reuses) an SDK-discovered session and sends one workflow-tagged turn for `/skill:ralplan`, `/skill:ultragoal`, or `/skill:team`, returning a durable `turn_id`, status, and artifact references. They use the same `sessions` mutation class and fail-closed workdir gating as `gjc_coordinator_start_session`, and emit a `delegation.started` event. Pass `await_completion: true` to use the durable bounded await/report path; `timeout_ms` and `poll_interval_ms` apply to that completion payload. Without it, the tool returns immediately after SDK acknowledgement. Pass `cwd` and `task`; set `allow_mutation: true` and a caller-provided `idempotency_key` only with startup mutation opt-in plus per-call consent. Optionally pass `mpreset` (same semantics as `gjc --mpreset `) to `gjc_coordinator_start_session` or a delegate tool to authoritatively activate a GJC model profile when starting a fresh session — it is resolved through the merged built-in/custom profile registry, applied from the first turn, and surfaced in status; unknown names are rejected with the available-profile listing, and reusing a session with a conflicting `mpreset` fails with `mpreset_conflict`. This is distinct from the advisory `model` prompt hint. Prefer these over manual `start_session` + `send_prompt` when delegating a whole workflow.\n\n`gjc_coordinator_register_session` registers an existing SDK-discoverable GJC session for coordinator control. It validates the workdir allowlist and session id, then verifies the broker's exact canonical workspace and endpoint generation before writing a credential-free session record. Optional tmux identifiers are retained only as advisory process metadata and are never machine-read.\n## Turn orchestration flow\n\nExternal coordinators should treat turns, not terminal scrollback, as the unit of work:\n\n1. Call `gjc_coordinator_start_session` with `allow_mutation: true` and `idempotency_key`.\n2. Call `gjc_coordinator_send_prompt` with `allow_mutation: true` and `idempotency_key`.\n3. Store the returned `turn_id`.\n4. Poll `gjc_coordinator_read_turn`, or call bounded `gjc_coordinator_await_turn`, until the turn is terminal.\n5. Pull `gjc_coordinator_list_questions` with the required `session_id`; it reconciles pending `workflow.gates.list` rows and returns bounded questions, diagnostics, and reconciliation state. Submit each pending row with `gjc_coordinator_submit_question_answer`.\n\n6. Use `gjc_coordinator_report_status` with `session_id` and `turn_id` to write explicit completion/failure evidence.\n Use `status: \"cancelled\"` for coordinator-policy cancellation, and `status: \"failed\"` plus `blocker` for provider/tool/task failures.\n\n`gjc_coordinator_send_prompt` returns versioned top-level routing fields that exactly mirror its nested durable `turn`: `status`, `queued`, and `delivered` equal `turn.status`, `turn.delivery.queued`, and `turn.delivery.delivered`; `active_turn_id` is the new turn id unless this response queued a follow-up, in which case it is the existing active turn id.\n\n```json\n{\n \"ok\": true,\n \"session_id\": \"gjc-coordinator-demo\",\n \"turn_id\": \"turn-00000000-0000-0000-0000-000000000000\",\n \"active_turn_id\": \"turn-00000000-0000-0000-0000-000000000000\",\n \"status\": \"active\",\n \"queued\": false,\n \"delivered\": true\n}\n```\n\nA session may have only one active turn by default. A second prompt is rejected with `active_turn_exists` unless the caller explicitly passes `queue: true` or `force: true`. Queued turns are durable and the next queued turn is promoted when the active turn reaches a terminal `gjc_coordinator_report_status`. Force supersedes the previous active turn and audits that state in the turn journal.\nCoordinator cancellation is recorded through `gjc_coordinator_report_status` with terminal `status: \"cancelled\"`; this updates durable turn state but does not control any process. If the correct policy is replacement work rather than cancellation, send the replacement prompt with `force: true` so the previous active turn is superseded and audited.\n\n`gjc_coordinator_read_turn` returns the authoritative durable turn and SDK-only advisory status. For the latest assistant output, use `gjc_coordinator_read_tail`; it queries `session.last_assistant` through the session SDK and returns only the requested bounded line suffix, never terminal output.\n\n```json\n{\n \"ok\": true,\n \"turn\": {\n \"schema_version\": 1,\n \"turn_id\": \"turn-00000000-0000-0000-0000-000000000000\",\n \"session_id\": \"gjc-coordinator-demo\",\n \"status\": \"completed\",\n \"final_response\": {\n \"text\": \"Done\",\n \"format\": \"markdown\",\n \"source\": \"report_status\",\n \"artifact_path\": null,\n \"truncated\": false\n },\n \"evidence\": [{ \"path\": \"artifact.txt\" }],\n \"error\": null\n },\n \"advisory_status\": {\n \"authority\": \"sdk\",\n \"live\": true,\n \"is_streaming\": false\n }\n}\n```\n\nThe coordinator MCP bridge is currently a durable polling/await surface. It does not expose a push subscription stream; external coordinators should poll `gjc_coordinator_read_coordination_status`, `gjc_coordinator_read_turn`, or bounded `gjc_coordinator_await_turn` instead of waiting for server-sent push events.\n\nExternal `session_id`, `turn_id`, and `question_id` values are validated before path use, and loaded records must match the requested session/turn owner.\n\n### Coordinator question pull loop\n\n`gjc_coordinator_list_questions` requires `session_id` and reconciles the session's pending `workflow.gates.list` rows on every call. Its bounded response contains public `questions`, `diagnostics`, and `reconciliation`; `status: \"pending\"` selects pending rows, while `status: \"open\"` remains a compatibility alias. More than one pending question may be returned. Public rows expose only the safe question shape, public option ids, and a fresh `answer_binding` for each pending row—never raw/private gate payloads or values.\n\n`gjc_coordinator_submit_question_answer` requires `session_id`, `turn_id`, `question_id`, `answer_binding`, `answer`, `idempotency_key`, and `allow_mutation: true`. Copy the identifiers and binding from the pending row and use the advertised answer shape. The bridge re-reconciles and revalidates ownership, pending state, and the binding before calling `workflow.gate_answer`; it never invokes generic `ask.answer`. An incomplete snapshot fails as `terminal_uncertain`; stale, terminal, missing, or ownership-mismatched rows are non-answerable. Restart can remint or quarantine gates, so re-list instead of reusing old rows. Identical idempotent replay returns the original accepted result; the same key with different arguments fails `idempotency_conflict`.\n\nThis pull-loop contract is independent of #2549/#2551 and unattended plain-CLI handling.\n\n## Coordinator event journal\n\nThe bridge persists a restart-safe event journal under the configured coordinator state namespace, for example:\n\n```text\n$GJC_COORDINATOR_MCP_STATE_ROOT///events/event-journal.jsonl\n```\n\nEach event is a bounded JSONL record with `schema_version`, monotonic namespace-local `seq`, stable `id`, `timestamp`, canonical `kind`, optional `session_id`/`turn_id`/`question_id`/`report_id`, short `summary`, optional `payload_ref`, and bounded scalar `metadata`. Full prompts, reports, final responses, and artifacts stay in their existing turn/report/artifact read paths; event records only point at them.\n\n`gjc_coordinator_watch_events` is a bounded long-poll MCP tool, not an unbounded stream. Inputs are `after_seq` (default `0`), optional `session_id`, optional `event_types`, `timeout_ms` capped at 30000, and `limit` capped at 100. If matching events already exist after `after_seq`, it returns immediately. Otherwise it waits for the event journal to change or for timeout. The response includes `events`, `latest_seq`, `timed_out`, and `transport: { \"mcp\": \"long_poll\", \"push_subscriptions\": false }`, so coordinators can persist `latest_seq` and resume safely after restart.\n\n`gjc_coordinator_read_coordination_status` keeps its existing report fields and now also includes `latest_event_seq` plus recent event summaries for snapshot-style consumers.\n\n## Generic controller config snippet\n\n```json\n{\n \"mcp_servers\": {\n \"gjc_coordinator\": {\n \"command\": \"gjc\",\n \"args\": [\"mcp-serve\", \"coordinator\"],\n \"env\": {\n \"GJC_COORDINATOR_MCP_WORKDIR_ROOTS\": \"/path/to/repo\",\n \"GJC_COORDINATOR_MCP_PROFILE\": \"team-a\",\n \"GJC_COORDINATOR_MCP_REPO\": \"project\",\n \"GJC_COORDINATOR_MCP_SESSION_COMMAND\": \"gjc --worktree\"\n },\n \"enabled\": true\n }\n }\n}\n```\n\n## Smoke check\n\n```bash\ngjc mcp-serve coordinator --check --json\n```\n\nExpected result includes `ok: true`, server name `gjc-coordinator-mcp`, and the GJC-named tool list. The JSON check is discovery-only and non-mutating: it retains those legacy fields and adds `catalog: { \"ready\": true, \"reason\": null }` and `broker`. `broker.discovery_status` is `ready`, `unavailable`, or `error`, with reason `null`, `absent_or_invalid`, `unsupported_state_version`, `discovery_access_denied`, or `discovery_read_failed`. `broker.operational_ready` is always `null`; the check does not connect, ensure/bootstrap, write, repair, or delete. `bootstrap_supported` is `true` and `bootstrap_attempted` is `false`. It does not expose broker authority, path, endpoint, process metadata, token, or raw error details. `gjc mcp-serve hermes --check --json` returns the identical coordinator check payload; its human output remains the server/tools summary.\n", "hotspot-map-successor.md": "# cpu-hotspot-map.json — successor pointer\n\n[`cpu-hotspot-map.json`](./cpu-hotspot-map.json) is **closed out**.

The file is a JSON object whose keys are keybinding action IDs and whose values are either one chord string or an array of chord strings. It is not read from `~/.gjc/agent/config.yml`, and there is no nested `keybindings` object.\n\n```json\n{\n \"app.commandPalette.open\": \"Ctrl+P\",\n \"app.model.cycleForward\": \"Alt+N\",\n \"app.model.selectTemporary\": \"Alt+P\",\n \"app.plan.toggle\": \"Alt+Shift+P\"\n}\n```\n\nChord names are case-insensitive and use the same notation shown in the UI, such as `Ctrl+P`, `Alt+N`, `Alt+Shift+P`, `Shift+Enter`, and `Ctrl+Backspace`.\n\nSet an action to an empty array to disable it:\n\n```json\n{\n \"app.stt.toggle\": []\n}\n```\n\n## Common action IDs\n\n| Action ID | Default | Meaning |\n| --- | --- | --- |\n| `app.commandPalette.open` | `Ctrl+P` | Open the command palette |\n| `app.model.cycleForward` | `Alt+N` | Cycle role models forward |\n| `app.model.cycleBackward` | `Alt+Shift+N` | Cycle role models backward |\n| `app.model.selectTemporary` | `Alt+P` | Pick a model temporarily for this session |\n| `app.model.select` | `Ctrl+L` | Open the model selector and set roles |\n| `app.plan.toggle` | `Alt+Shift+P` | Toggle plan mode |\n| `app.history.search` | `Ctrl+R` | Search prompt history |\n| `app.tools.expand` | `Ctrl+O` | Toggle tool-output expansion |\n| `app.thinking.toggle` | `Ctrl+T` | Toggle thinking-block visibility |\n| `app.thinking.cycle` | `Shift+Tab` | Cycle thinking level |\n| `app.editor.external` | `Ctrl+G` | Edit the draft in `$VISUAL` / `$EDITOR` |\n| `app.message.followUp` | _(none)_ | Optional remap for a follow-up message; `Ctrl+Enter` is reserved for editor newline |\n| `app.message.queue` | `Alt+Enter` (`Alt+Q` on darwin/win32) | Explicitly queue a message for the next turn |\n| `app.message.dequeue` | `Alt+Up` | Dequeue a queued message back into the editor |\n\n| `app.clipboard.copyLine` | `Alt+Shift+L` | Copy the current line |\n| `app.clipboard.copyPrompt` | `Alt+Shift+C` | Copy the whole prompt |\n| `app.stt.toggle` | `Alt+H` | Toggle speech-to-text recording |\n| `app.irc.sidebar.toggle` | `Alt+I` | Toggle IRC sidebar |\n\nOlder unqualified action names are migrated when `keybindings.json` is loaded, but new docs and new configs should use the namespaced action IDs above.\n\nOn macOS and native Windows terminals, GJC defaults `app.message.queue` to `Alt+Q`; Windows Terminal and PowerShell commonly reserve `Alt+Enter` for fullscreen before GJC can receive it.

For example `Enter` maps to both input submit and selection confirm, and `Ctrl+C` maps to both input copy and selection cancel. These are not conflicts — only one context is active at a time.\n\nTo audit the registry for keys whose default binding is claimed by more than one action, use `detectDefaultKeyCollisions(definitions)` from `@gajae-code/tui/keybindings`. It returns one entry per colliding key with the list of claiming action IDs, which is useful when adding new defaults or reviewing the surface.

The project directory contains at least one of the server's `rootMarkers`.\n2. The server binary is a trusted external executable. Project-local binaries, including paths reached through symlinks, are rejected.\n\nNo configuration is required for common setups. The built-in server list covers most popular languages; see [`defaults.json`](../packages/coding-agent/src/lsp/defaults.json) for the full set.\n\n## Config file locations\n\nGJC merges LSP config from multiple files, lowest to highest priority:\n\n| Priority | Location |\n|----------|----------|\n| 5 (lowest) | `~/lsp.json`, `~/.lsp.json`, `~/lsp.yaml`, `~/.lsp.yaml` |\n| 4 | Preloaded trusted external plugin LSP config outside the project (internal loader support; no current CLI/startup producer) |\n| 3 | `~/.gjc/agent/lsp.json`, `~/.gjc/agent/lsp.yaml`, `~/.gemini/lsp.*` |\n| 2 | `/.gjc/lsp.json`, `/.gjc/lsp.yaml`, `/.gemini/lsp.*` |\n| 1 (highest) | `/lsp.json`, `/.lsp.json`, `/lsp.yaml` |\n\nEach location accepts both `.json` and `.yaml` / `.yml` variants, as well as hidden-file versions (`.lsp.json`, `.lsp.yaml`). Configuration is merged in order, but project-controlled files can only control declarative server matching, activation, and capabilities. They cannot define or override a server's `command`, `args`, executable, client factory, `initOptions` / `initializationOptions`, or `settings`; opaque options that can instruct a trusted server belong to trusted user configuration.\n\nThe recommended trusted user configuration is `~/.gjc/agent/lsp.json` (or YAML equivalent). Legacy user-wide `~/.gemini/lsp.*` and home-root `~/lsp.*` / `~/.lsp.*` files are also outside the project and may define launch settings and opaque server options, including custom servers. Project files may refine declarative matching and activation fields of built-in or user-defined servers.\n\n**Recommended locations:**\n\n- Trusted user launch settings, `initOptions`, and `settings` → `~/.gjc/agent/lsp.json`\n- Project-specific matching and activation → `/.gjc/lsp.json`\n\n> **Note:** The presence of any LSP config file disables auto-detection. When at least one file is found, GJC skips the binary-scan phase and loads matching, available, non-disabled servers using trusted launch definitions.\n\n## File shape\n\nBoth JSON and YAML are accepted. The top-level object can use either a `servers` wrapper key or a flat map directly:\n\n```json\n{\n \"servers\": {\n \"server-name\": { ... }\n },\n \"idleTimeoutMs\": 300000\n}\n```\n\nor (flat, without the `servers` wrapper):\n\n```json\n{\n \"server-name\": { ... },\n \"idleTimeoutMs\": 300000\n}\n```\n\nTop-level keys:\n\n- `servers` — map of server name to `ServerConfig` (optional wrapper; flat form is equivalent)\n- `idleTimeoutMs` — shut down idle language servers after this many milliseconds; disabled by default\n\n## ServerConfig fields\n\n| Field | Type | Required | Description |\n|-------|------|----------|-------------|\n| `command` | `string` | trusted user config only | Server executable name or absolute path; project configuration cannot set or override it |\n| `args` | `string[]` | no | Launch arguments; trusted user config only |\n| `fileTypes` | `string[]` | yes | File extensions this server handles, e.g. `[\".ts\", \".tsx\"]` |\n| `rootMarkers` | `string[]` | yes | Files/dirs that indicate a project root; glob patterns (e.g. `*.cabal`) are supported |\n| `initOptions` | `object` | trusted user config only | Sent as `initializationOptions` during LSP handshake |\n| `settings` | `object` | trusted user config only | Workspace settings pushed via `workspace/didChangeConfiguration` |\n| `disabled` | `boolean` | no | Set to `true` to disable this server entirely |\n| `warmupTimeoutMs` | `number` | no | Startup timeout in ms for this server (overrides the global default) |\n| `isLinter` | `boolean` | no | Mark server as linter/formatter only; excluded from type-intelligence operations (hover, go-to-definition, etc.) |\n| `capabilities` | `object` | no | Opt-in server-specific features; see [Capabilities](#capabilities) |\n\n`resolvedCommand` is populated automatically at runtime — do not set it manually.\n\n### Capabilities\n\nThe `capabilities` object enables optional server-specific features that GJC supports on a per-server basis:\n\n```json\n{\n \"capabilities\": {\n \"flycheck\": true,\n \"ssr\": true,\n \"expandMacro\": true,\n \"runnables\": true,\n \"relatedTests\": true\n }\n}\n```\n\nAll fields are boolean and optional. They are currently used by `rust-analyzer`.\n\n## Common recipes\n\n### Override a built-in server's settings from trusted user configuration\n\nOpaque server settings may contain process-affecting instructions, so place these partial overrides in trusted user configuration such as `~/.gjc/agent/lsp.json`:\n\n```json\n{\n \"servers\": {\n \"typescript-language-server\": {\n \"settings\": {\n \"typescript\": {\n \"preferences\": {\n \"quoteStyle\": \"single\"\n }\n }\n }\n }\n }\n}\n```\n\n```yaml\nservers:\n gopls:\n settings:\n gopls:\n gofumpt: false\n staticcheck: false\n```\n\n### Disable a built-in server\n\n```json\n{\n \"servers\": {\n \"eslint\": {\n \"disabled\": true\n }\n }\n}\n```\n\n### Register a custom server\n\nRegister custom servers in the canonical trusted user configuration, `~/.gjc/agent/lsp.json`. New servers require `command`, `fileTypes`, and `rootMarkers`; `args` is optional. Project configuration cannot register a launch definition or override a server's command, arguments, executable, or client factory.\n\n```json\n{\n \"servers\": {\n \"my-lsp\": {\n \"command\": \"my-lsp-server\",\n \"args\": [\"--stdio\"],\n \"fileTypes\": [\".xyz\"],\n \"rootMarkers\": [\".xyz-project\", \".git\"]\n }\n }\n}\n```\n\n### Set a global idle timeout\n\nShut down language servers that have been inactive for more than five minutes:\n\n```json\n{\n \"idleTimeoutMs\": 300000\n}\n```\n\n### Disable a server for one project, keep it globally\n\nPlace the override in `/.gjc/lsp.json`:\n\n```json\n{\n \"servers\": {\n \"pylsp\": {\n \"disabled\": true\n }\n }\n}\n```\n\nThe user-level config in `~/.gjc/agent/lsp.json` is unaffected; pylsp is only suppressed in this project.\n\nWhen multiple built-in primary servers support the same file, a default server can list lower-precedence servers in `supersedes`. For example, `csharp-ls` supersedes `omnisharp` only when both C# servers are installed and detected; if `csharp-ls` is unavailable, `omnisharp` remains the fallback.\n\n## lspmux\n\n`GJC_DISABLE_LSPMUX=1` is the canonical opt-out. `PI_DISABLE_LSPMUX=1` is a supported compatibility alias. A truthy value for either variable disables lspmux probing and wrapping.\n\n## Built-in server list\n\nThe following servers ship in `defaults.json` and are eligible for auto-detection:\n\n| Server key | Language(s) | Binary |\n|---|---|---|\n| `rust-analyzer` | Rust | `rust-analyzer` |\n| `clangd` | C, C++, ObjC | `clangd` |\n| `zls` | Zig | `zls` |\n| `gopls` | Go | `gopls` |\n| `typescript-language-server` | TypeScript, JavaScript | `typescript-language-server` |\n| `denols` | TypeScript, JavaScript (Deno) | `deno` |\n| `biome` | TS/JS/JSON (linter) | `biome` |\n| `eslint` | TS/JS/Vue/Svelte (linter) | `vscode-eslint-language-server` |\n| `vscode-html-language-server` | HTML | `vscode-html-language-server` |\n| `vscode-css-language-server` | CSS, SCSS, Less | `vscode-css-language-server` |\n| `vscode-json-language-server` | JSON | `vscode-json-language-server` |\n| `tailwindcss` | HTML, CSS, TS/JS | `tailwindcss-language-server` |\n| `svelte` | Svelte | `svelteserver` |\n| `vue-language-server` | Vue | `vue-language-server` |\n| `astro` | Astro | `astro-ls` |\n| `pyright` | Python | `pyright-langserver` |\n| `basedpyright` | Python | `basedpyright-langserver` |\n| `pylsp` | Python | `pylsp` |\n| `ruff` | Python (linter) | `ruff` |\n| `jdtls` | Java | `jdtls` |\n| `kotlin-lsp` | Kotlin | `kotlin-lsp` |\n| `metals` | Scala | `metals` |\n| `hls` | Haskell | `haskell-language-server-wrapper` |\n| `ocamllsp` | OCaml | `ocamllsp` |\n| `elixirls` | Elixir | `elixir-ls` |\n| `erlangls` | Erlang | `erlang_ls` |\n| `gleam` | Gleam | `gleam` |\n| `solargraph` | Ruby | `solargraph` |\n| `ruby-lsp` | Ruby | `ruby-lsp` |\n| `rubocop` | Ruby (linter) | `rubocop` |\n| `bashls` | Bash, Zsh | `bash-language-server` |\n| `lua-language-server` | Lua | `lua-language-server` |\n| `intelephense` | PHP | `intelephense` |\n| `phpactor` | PHP | `phpactor` |\n| `csharp-ls` | C# | `csharp-ls` |\n| `omnisharp` | C# | `omnisharp` |\n| `yamlls` | YAML | `yaml-language-server` |\n| `terraformls` | Terraform | `terraform-ls` |\n| `dockerls` | Dockerfile | `docker-langserver` |\n| `helm-ls` | Helm | `helm_ls` |\n| `nixd` | Nix | `nixd` |\n| `nil` | Nix | `nil` |\n| `ols` | Odin | `ols` |\n| `dartls` | Dart | `dart` |\n| `marksman` | Markdown | `marksman` |\n| `texlab` | LaTeX | `texlab` |\n| `graphql` | GraphQL | `graphql-lsp` |\n| `prismals` | Prisma | `prisma-language-server` |\n| `vimls` | Vim script | `vim-language-server` |\n| `emmet-language-server` | HTML, CSS, JSX | `emmet-language-server` |\n| `sourcekit-lsp` | Swift | `sourcekit-lsp` |\n| `swiftlint` | Swift (linter) | `swiftlint` |\n| `tlaplus` | TLA+ | `tlapm_lsp` |\n", diff --git a/packages/coding-agent/src/modes/acp/acp-agent.ts b/packages/coding-agent/src/modes/acp/acp-agent.ts index 8c03ab67f3..466c48d7b8 100644 --- a/packages/coding-agent/src/modes/acp/acp-agent.ts +++ b/packages/coding-agent/src/modes/acp/acp-agent.ts @@ -778,10 +778,14 @@ export class AcpAgent implements Agent { async setSessionMode(params: SetSessionModeRequest): Promise { if (params.modeId !== ACP_DEFAULT_MODE_ID && params.modeId !== ACP_PLAN_MODE_ID) throw new Error(`Unsupported ACP mode: ${params.modeId}`);
