Anatomy SkillThe open-source Anatomy skill, run for you
Write a technical concept. The Anatomy skill invents a machine whose working is the concept, builds it from dozens of small shaded parts, checks every joint, and you download a 1080p video and an interactive HTML figure about an hour later.

A REAL FIGURE
Built by this service from the idea “explain how a token bucket rate limiter works”. The metering wheel drops one coin into the tube per turn, two turns a second; every request pulls the slide and takes the bottom coin; once the tube is empty the pull takes nothing and the request is rejected. Hover the figure to raise the request rate.
This figure took the skill 21 minutes, three rounds of its own checks and one geometry fix (a spring that ran through the tube). It is one actual output; every figure is designed fresh for its idea.
Brief your own ideaHOW IT WORKS
One or two sentences about the technical concept. Within seconds you see two machines the skill could build for it, with what moves and what the motion means.
Choose the metaphor you like, the theme (light or paper-dark) and the aspect ratio, and confirm one credit. The build is queued at once.
The skill builds the parts, checks its own work, records the tour and emails you. Download the MP4, the HTML figure, the cover image and the embed code.
WHAT IS THE ANATOMY SKILL
The Anatomy skill is an open-source Claude Code skill by @wheresryan22 that explains a technical idea by building a real, working machine out of dozens of small, shaded isometric parts. anatomyskill.org runs that skill for you: write the idea, approve the machine, and about an hour later download a 1080p video and an interactive HTML figure you can embed.
The skill is free to install from GitHub and run in your own agent. This site exists for the people who want the figure without the hour at the terminal: the same skill, pinned to a tested version, with the checks, the recording and the delivery done for them. The skill on GitHub
WHY A FIGURE, NOT A CLIP
The Anatomy skill does not draw boxes and arrows. It invents a machine whose working is the concept: a token bucket becomes a coin dispenser, a cache key becomes a pin-tumbler lock. People understand it because they recognise the machine.
Base plate on feet, posts, rails, springs, knurled knobs, a dial that reads a true number. Each figure has 40 to 80 shaded parts, and every readout comes from the same small model that moves them.
Each build runs the skill’s own checks: every line ends on something, nothing passes through anything, and the figure is reviewed at 4× in both themes. A figure that fails twice is not delivered and costs nothing.
You get a 1080p MP4 of the idle tour for landing pages and talks, plus the standalone HTML figure that moves under the pointer, for docs and blog posts. Embed code is included.
WRITING A GOOD IDEA
Anatomy is an open-source skill for Claude Code (and Codex, OpenCode, Antigravity) by @wheresryan22, released under the MIT license. Given a technical idea it builds an interactive isometric figure: a real machine made of many small shaded parts whose working explains the concept. anatomyskill.org is an independent hosted service that runs that skill for you; it is not affiliated with the author.
One figure: a 1080p MP4 of its idle tour (about 15 to 30 seconds), the standalone interactive HTML page in the theme you chose, a cover image and an embed snippet. Everything is yours to use commercially.
About an hour. The skill writes a parts list, builds the geometry, checks it, fixes what the checks find and records the video. You get an email when it is ready, and the progress page shows each step.
Anything with a mechanism: algorithms, data structures, protocols, systems, physical processes. The skill draws machines, instruments, tools and furniture, not people, maps or marketing slogans. The brief step tells you at once if an idea has no mechanism to build, and it costs nothing.
You would not need to if you already run Claude Code and have an hour to spend per figure. The hosted service is for people who want the result without installing anything, keeping an agent session open, recording the video and checking the output themselves.
Every figure passes the skill’s own geometry and line checks before delivery; one that fails twice is not delivered and the credit comes back. If a delivered figure is not what you wanted, you can rebuild it once with the other machine at no charge.
Yes. The HTML page is self-contained (no external requests) and the embed snippet is an iframe with the figure hosted here. You can also download the HTML and host it yourself.
One idea, one credit, and the Anatomy skill builds the figure for you.
