opus-js-animations is a Claude Code skill and plugin that directs a film before writing it: it asks for the sound source, analyses the audio, asks about look and pacing, and pitches a timed treatment. After approval it writes the film in Canvas 2D or Three.js and renders it frame-exact in headless Chrome for Reels, TikTok, Shorts or YouTube. Install through the plugin marketplace or copy the skill.
