huashu-motion

Introduction

huashu-motion is an AI skill pack following the Agent Skills protocol that lets coding agents like Claude Code and Codex directly produce commercial-grade product promo animations. Just provide a one-line brief or a product URL, and the agent handles everything from planning and production to scoring.

Problem Solved

Traditional product videos require design, motion graphics, editing, and scoring. huashu-motion hands these tasks to the agent, lowering the barrier to video production. A built-in editor also lets you point directly at the canvas to mark changes for precise iteration.

Key Capabilities

• Automated production pipeline: The agent reads product info, offers three keyframe directions to choose from, then writes a timing sheet, generates the animation, and composes the score automatically.
• Point-and-edit: In the browser editor, press C and click anywhere on the canvas to leave feedback. Comments carry timestamp, scene, element, and source code location data. The agent edits only the specified area, previews refresh in place, and undo is supported.
• Composer mode scoring: Uses ABC notation to generate plain-text scores aligned to each scene, performed with grand piano, strings, and drum kit samples. Music is generated locally—no paid APIs required.
• Data narration & voiceover support: Converts CSV data into explainer videos; import recordings for word-level alignment so visuals switch with speech, subtitles are auto-generated, and the score ducks under vocals.
• Multi-format export: Export MP4, MOV (with alpha channel), WebM, GIF, or generate a shareable Web page with a player and source code.
• Experience memory: Reads past preferences before starting and collects your feedback afterward to build experience.

Who It's For

Ideal for developers and creators who use coding agents (like Claude Code or Codex) and want to quickly produce launch videos, data explainers, or motion demos for their products. Currently tested only on macOS.
