Skill: autogame-17/feishu-evolver-wrapper (version 1.8.0)

--- name: feishu-evolver-wrapper description: Feishu-integrated wrapper for the capability-evolver. Manages the evolution loop lifecycle (start/stop/ensure), sends rich Feishu card reports, and provides dashboard visualization. Use when running evolver with Feishu reporting or when managing the evolution daemon. --- # Feishu Evolver Wrapper A lightweight wrapper for the `capability-evolver` skill. It injects the Feishu reporting environment variables (`EVOLVE_REPORT_TOOL`) to enable rich card reporting in the Master's environment. ## Usage ```bash # Run the evolution loop node skills/feishu-evolver-wrapper/index.js # Generate Evolution Dashboard (Markdown) node skills/feishu-evolver-wrapper/visualize_dashboard.js # Lifecycle Management (Start/Stop/Status/Ensure) node skills/feishu-evolver-wrapper/lifecycle.js status ``` ## Architecture - **Evolution Loop**: Runs the GEP evolution cycle with Feishu reporting. - **Dashboard**: Visualizing metrics and history from `assets/gep/events.jsonl`. - **Export History**: Exports raw history to Feishu Docs. - **Watchdog**: Managed via OpenClaw Cron job `evolver_watchdog_robust` (runs `lifecycle.js ensure` every 10 min). - Replaces fragile system crontab logic. - Ensures the loop restarts if it crashes or hangs.
