alchaincyf · Agent launch-film skill

huashu-motion

huashu-motion is an Agent Skills-standard skill from alchaincyf that lets a coding agent such as Claude Code or Codex make a product launch film from a one-line request. The agent reads the product, offers three directions, writes the film and composes the soundtrack as ABC notation, which is played with instrument samples or synthesised sounds. It then opens a browser editor where the user clicks a frame and types a comment, and the agent changes only that element. Each film is a single index.html built with GSAP, Canvas, Three.js or SVG, with no video generation model involved. The author reports a 22-second film made with DeepSeek V4.1 Flash in under half an hour, and a 53-second launch film for the project itself. It is MIT-licensed, has 2,489 stars and reached v0.3.1 on 22 October 2026. It needs Node 22 or later, Chrome and FFmpeg, and has only been tested on macOS.
