Overview

HttpServer runs an embedded WEBrick HTTP server with WebSocket support.

Routes:

GET  /ws                     → WebSocket upgrade (all real-time communication)
*    /api/*                  → JSON REST API (sessions, tasks, schedules)
GET  /**                     → static files served from lib/clacky/web/ directory

Defined Under Namespace

BRAND_HEARTBEAT_MUTEX =

Process-wide mutex guarding heartbeat trigger state. Used by #trigger_async_heartbeat! to ensure only one heartbeat Thread is in flight at a time, no matter how many concurrent /api/brand/status requests arrive from the Web UI poller.

Mutex.new
BRAND_DIST_REFRESH_MUTEX =

Mutex + inflight flag for async distribution refresh. Mirrors the heartbeat pattern above so the same guarantees hold: at most one refresh thread per process regardless of how many concurrent /api/brand/status polls arrive from the Web UI.

Mutex.new
IGNORED_FILE_ENTRIES =

Lists one directory level inside the session's working_dir (lazy, per-layer). Path traversal outside working_dir is rejected. Noisy dirs are hidden.

%w[.git .svn .hg node_modules .DS_Store .bundle vendor/bundle tmp .sass-cache].freeze
PROFILE_USER_AGENTS_DIR =

── Profile API (USER.md / SOUL.md) ──────────────────────────────

User can override the built-in defaults by writing their own ~/.clacky/agents/USER.md and ~/.clacky/agents/SOUL.md. These endpoints let the Web UI read and edit those files.

File.expand_path("~/.clacky/agents").freeze
PROFILE_MAX_BYTES =

Hard limit; prevents runaway content.

50_000
MEMORIES_DIR =

── Memories API (~/.clacky/memories/*.md) ───────────────────────

Long-term memories are plain Markdown files with YAML frontmatter stored under ~/.clacky/memories/. These endpoints let the user inspect, edit, create, and delete them from the Web UI.

File.expand_path("~/.clacky/memories").freeze
MEMORY_MAX_BYTES =

#api_benchmark_session_models(session_id, _req, res) ⇒ Object

POST /api/sessions/:id/benchmark

Speed-test every configured model in one shot so the user can pick the fastest available model for this session. We send a minimal one-token request to each model in parallel (one thread per model) and measure total HTTP duration — for non-streaming calls this equals the user's perceived time-to-first-token, so the field is named ttft_ms for forward-compatibility with a future streaming implementation.

Cost note: each request is max_tokens: 1 + a 2-byte prompt, so the total cost across a dozen models is well under one cent.

Response shape:

{
ok: true,
results: [
  { model_id: "...", model: "...", ttft_ms: 812, ok: true },
  { model_id: "...", model: "...", ok: false, error: "timeout" },
  ...
]
}

Useful for debugging — user clicks "download" in the WebUI status bar and we can ask them to attach the zip to a bug report.

POST /api/internal/ocr-image Internal endpoint used by parser scripts (e.g. pdf_parser_vlm.py) to transcribe a single image via the configured OCR sidecar. Localhost- only by virtue of the standard auth path: when the server binds to 127.0.0.1 (@localhost_only), check_access_key returns true without requiring a token, so parsers running on the same host can call this endpoint with no extra wiring.

Request: multipart/form-data with field "image" (binary), optional "prompt" OR JSON body { "data_url": "data:image/png;base64,...", "prompt": "..." } Response: { ok: true, text: "..." } or { ok: false, message: "..." }

#api_mcp_call(name, req, res) ⇒ Object

POST /api/mcp/:name/call body: { tool: "...", arguments: ... } Forwards a tools/call to the configured MCP server and returns its raw result. Subagents call this from their shell tool via curl — there is no Ruby-side bridge tool anymore.

POST /api/channels/:platform/send Proactively send a message to a user via the given IM platform.

Body:

{ "message": "hello",            # required
"user_id": "some_user_id" }    # optional — defaults to most-recently active user

Response:

200 { ok: true }
400 { ok: false, error: "..." }  — missing/invalid params or platform not running
503 { ok: false, error: "..." }  — no known users (nobody has messaged the bot yet)

Constraints:

- The platform adapter must be running (channel must be enabled + connected).
- For Weixin (iLink protocol), a context_token is required per message. This is
automatically looked up from the in-memory cache populated by inbound messages.
If no token exists for the target user (i.e. the user has never messaged the bot
in this server session), the message cannot be delivered.

#api_store_skills(res) ⇒ Object

GET /api/brand/skills Fetches the brand skills list from the cloud, enriched with local installed version. Returns 200 with skill list, or 403 when license is not activated. If the remote API call fails, falls back to locally installed skills with a warning. GET /api/store/skills Returns the public skill store catalog from the OpenClacky Cloud API. Requires an activated license — uses HMAC auth with scope: "store" to fetch platform-wide published public skills (not filtered by the user's own skills). Falls back to the hardcoded catalog when license is not activated or API is unavailable.

PATCH /api/config/models/:id Body: any subset of { model, base_url, api_key, anthropic_format, type } Rules (the whole reason we moved off bulk save):

- Missing key  → field untouched
- api_key with "****" (masked display value) → IGNORED (never overwrites)
- api_key empty string → IGNORED (defensive; treat as "not changed")
- api_key real non-masked value → stored
- type="default" transparently clears the marker on other models
- Unknown id → 404

    working directory for the agent

  • permission_mode (Symbol) (defaults to: :confirm_all) —

    :confirm_all (default, human present) or :auto_approve (unattended — suppresses request_user_feedback waits)

#create_default_session ⇒ Object

Auto-restore persisted sessions (or create a fresh default) when the server starts. Skipped when no API key is configured (onboard flow will handle it).

Strategy: load the most recent sessions from ~/.clacky/sessions/ for the current working directory and restore them into @registry so their IDs are stable across restarts (frontend hash stays valid). If no persisted sessions exist, fall back to creating a brand-new default session.

#interrupt_session(session_id) ⇒ Object

Interrupt a running agent session.

Thread#raise is best-effort: it unblocks most pure-Ruby waits and Faraday reads, but can't reach a thread stuck in a C-extension syscall until that syscall returns. We raise once and return immediately.

Correctness of the takeover does not depend on the old thread dying promptly: each new task claims a fresh epoch (see run_agent_task), and any status write or UI broadcast from a superseded thread is fenced off by that epoch. A stale thread that lingers in a syscall is harmless — it self-terminates at the next check_stale! checkpoint, or when the syscall returns; either way it can no longer touch the live session.

#mask_api_key(key) ⇒ Object

Mask API key for display: show first 8 + last 4 chars, middle replaced with **** Mask an api_key for safe display / transport to the browser.

Contract: the returned string MUST contain "****" so callers (incl. the frontend) can reliably detect "this is a display placeholder, not a real key" and refuse to treat it as input. The old behaviour of returning the raw value for short keys was a correctness bug — it leaked short keys in plaintext to GET /api/config, and it let short masked values slip past the frontend's mask-detection.

#trigger_async_distribution_refresh! ⇒ Object

Fire a public-distribution refresh in a background Thread.

Used for installs that have a package_name configured via install.sh but haven't activated a license yet — they would otherwise never see the brand logo / theme / homepage_url until activation. See BrandConfig#refresh_distribution! for the end-to-end flow.

Contract mirrors #trigger_async_heartbeat!:

* At most one refresh Thread in flight process-wide.
* Caller never waits — Web UI first paint is not blocked on network.
* All exceptions are swallowed; a refresh failure must not crash the
server or leak through the web stack.

#trigger_async_heartbeat! ⇒ Object

Fire a heartbeat in a background Thread without blocking the caller.

Contract:

* Only one heartbeat Thread may be running at any moment across the
whole process. If one is already in flight, this call is a no-op.
* The caller never waits: it returns immediately after (at most)
spawning the Thread.
* The Thread rescues everything so a network failure cannot kill the
server or leak an exception through the web stack.
