Response:

{ branded: true, needs_activation: true,
  product_name: "JohnAI" }                     → license key required
{ branded: true, needs_activation: false,
  product_name: "JohnAI", warning: "..." }     → activated, possible warning

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.

#api_tool_browser(req, res) ⇒ Object

GET /api/channels Returns current config and running status for all supported platforms. POST /api/tool/browser Executes a browser tool action via the shared BrowserManager daemon. Used by skill scripts (e.g. feishu_setup.rb) to reuse the server’s existing Chrome connection without spawning a second MCP daemon.

Request body: JSON with same params as the browser tool

{ "action": "snapshot", "interactive": true, ... }

Response: JSON result from the browser tool

Parameters:

  • name (String) —

  • working_dir (String) —

    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.
