alchaincyf has open-sourced huashu-motion on GitHub, an Agent Skills protocol-compliant skill that enables agents like Claude Code and Codex to create animated promotional videos with auto-generated music based on product info. The project gained 914 stars in two days. Unlike video generation models, the output is an index.html file rendered via GSAP and Canvas code. Music is generated locally using ABC notation and instrument samples without paid APIs. Users can direct agents to modify specific areas by clicking on frames within a browser editor. It requires Node 22, Chrome, and FFmpeg, and has been tested on macOS. The author also demonstrated low-cost production using DeepSeek V4.1 Flash, costing approximately 1.95 RMB in under half an hour.
This open-source agent skill allows intelligent agents like Claude Code to directly produce promotional videos with music and enables targeted modifications by clicking on frames. The methods and examples are complete and reproducible.
