OpenAI Codex plugin for HyperFrames — an open-source video rendering framework where HTML is the source of truth for video.

Five skills for authoring and rendering video:

• hyperframes — composition authoring (HTML + CSS + GSAP), visual styles, palettes, house style, motion principles, transitions, captions, audio-reactive visuals
• hyperframes-cli — hyperframes init / lint / preview / render / transcribe / tts / doctor / browser
• hyperframes-registry — hyperframes add to install reusable blocks and components (social overlays, shader transitions, data viz, effects)
• gsap — tweens, timelines, easing, stagger, performance
• website-to-hyperframes — 7-step pipeline that captures a URL and produces a finished video

The skills invoke the hyperframes CLI via npx hyperframes, which needs:

• Node.js ≥ 22
• FFmpeg on PATH

See hyperframes.heygen.com/quickstart for full setup.

The skills are authored in heygen-com/hyperframes (under skills/ at the repo root) and mirrored here. File issues about skill content on that repo.
