The skill wraps JianYing, the Chinese edition of CapCut, in a Python API called JyWrapper, so an agent can generate drafts, import media, add subtitles, text and keyframe animations, apply filters, effects and transitions, record the screen with smart zoom, add TTS voiceover and background music, compose web-based effects and export projects. It works on macOS, on Apple Silicon and Intel, and on Windows, and supports draft_info.json drafts from version 5.9 onward.
Rule files describe the mandatory setup code, core save and export operations, CLI conventions, media import including a 30m/360p profile for AI video analysis, text, keyframes, effects, recording, web VFX, generative editing and audio. A draft inspector script lists drafts and shows summaries. Editing scripts belong in the user's own project, not inside the skill folder, and starting JyProject with overwrite=True can repair a corrupted draft. The SKILL.md mixes Chinese and English.
