Watch a tutorial or lecture video (URL or local path) and produce structured study notes. Downloads with yt-dlp, detects scene changes with ffmpeg, pulls a timestamped transcript (captions or Whisper API fallback), and writes a section-by-section markdown notes file with embedded screenshots to ~/claude-watch/library/<slug>/.

Add hand-gesture cursor control to any existing website. Replaces or augments the mouse cursor with MediaPipe Hand Landmarker tracking via webcam. Index finger controls cursor, fist gesture clicks, edge-zone scrolling. Works with any framework (React, Vue, Svelte, Next.js, vanilla HTML, etc.). TRIGGER: user wants hand tracking, gesture control, webcam cursor, or touchless navigation on their website.

Use when the user asks for UI screen generation, mockups, or design work powered by Google Stitch. Activates the Stitch MCP tools (generate_screen_from_text, edit_screens, get_screen, create_project) to produce high-fidelity HTML screens and screenshots from text prompts. Also handles prompt enhancement and design-system consistency via the bundled stitch-design workflow.
