How to add the skill
From the original GitHub repository, download the source ZIP and extract the whole repository folder with its supporting files.
For Claude Code, place the folder in .claude/skills/anatomy/. For Codex, use .agents/skills/ in your project. Open your project and ask your assistant to use anatomy with your own request.
Output
How it was made
Example input
Use the anatomy skill to build a music box with glass sides: a pinned cylinder plucks an 18-tooth steel comb, a key winds the spring, and a fan governor keeps the tempo. Light theme, vertical 1080 × 1920. Open the lid, wind the key, play an original waltz with each note synced to its pin, explode the parts, reassemble, and loop. Export an MP4 with sound.
Test notes
A 26-second vertical MP4 with synced sound: the lid opens, the key winds, an original waltz plays pin by pin, and the parts come apart and back together in a seamless loop.
- Built the music box with the skill’s kit and rendered 780 frames in headless Chrome.
- Checked key frames, close-ups, and the exploded view for depth order by eye.
- Drove the pins, comb, and synthesized audio from one shared model so each note lands on its pluck.
Wrote the timeline, camera moves, captions, original melody, and audio synthesis as project code around the skill, then exported the MP4 with ffmpeg.
One example generated in a Claude Code session using Opus 5.5. The skill’s geometry audit and line-end check were not run. The audio is synthesized in code. No skill-free comparison or independent security audit.
