A free, fully local agent skill for Claude Code, Codex, or Cursor that turns a topic into an animated narrated explainer: the agent writes an HTML/GSAP animation and script, Edge's free neural TTS voices it, headless Chromium records the page timed to the audio, and FFmpeg muxes in sound. No API keys, subscriptions, or watermarks.
