What it does
Anima turns a request such as "show how cocaine and amphetamine act differently at the dopamine transporter" into a standalone HTML page with an isometric figure. It shows real structures instead of generic icons: receptors, transporters, vesicles, brain regions and skeletal formulas. The mechanism toggles with buttons: block a receptor, change glucose, switch the substance. One small model drives the readout beside it. The skill first sizes the job (Figure, Hero or Epic), collects sources before drawing, then builds the page and checks it the way a reviewer would: zoomed in, in both light and dark themes and at phone width. Every number on screen carries a source with its conditions, and what could not be verified is left out. Figures separate established facts from one leading model, and rodent data from human data. Drugs are explained by mechanism only, with no doses, routes or advice. The examples folder holds seven ready figures built with `node examples/<name>/build.mjs`.
Who it is for. Biology teachers, science writers and students who need a clear mechanism figure with citations.
Good fit when
- A lecture needs to show how D1 and D2 receptors change cAMP differently in a neuron
- An article has to explain how semaglutide acts on a pancreatic beta cell, with figures from the drug label
- You want a live page on the brain reward pathway with a note that it is one model
- You want to walk through how CRISPR-Cas9 finds and cuts a target, with a guide-mismatch toggle
Not a fit when
- You need a medical decision or dosing advice: the figures explain mechanism only
- You need a figure outside biology: the skill is built for anatomy, cells and molecules
- You need a static picture for print: the result is an interactive page
Example request
/anima visualize semaglutide acting on a pancreatic beta cell, with glucose-dependent insulin release, cited label numbers and an educational-use noteLimitations
Claude Code and Node.js 20.10 or newer are required. Chrome or Chromium is needed only for the capture and verification scripts. The agent looks up sources itself, so check the citations and numbers in a finished figure against the originals, especially on medical topics. Figures do not replace a textbook and are no treatment guide. The latest changes in the repository are from October 2026, with no versions or releases. WebGL in figures is optional; the base drawing is built from SVG.
How to disable. Remove the skill folder from the Claude Code skills directory. Built HTML pages stay wherever you saved them.
FAQ
How do I invoke Anima?
In Claude Code type `/anima` and describe the subject, mechanism, audience and format, for example a standalone HTML page. The skill sizes the job itself: Figure, Hero or Epic.
Where do the numbers on the figure come from?
The agent collects sources before drawing, and each number is labelled with its source and measurement conditions. A number that could not be verified is not shown.
Can I open the examples without installing?
Yes, the author hosts all the figures at anima.arcumet.com. From a clone you can open them from the examples folder.
Does the skill discuss drug doses?
No, by the skill's rules drug figures explain mechanism only: no doses, routes, schedules or recommendations.
Is the light theme built separately?
Each figure builds in both dark and light themes. Add `--light` to the build command for the light one.

README in short
The project description explains why the skill exists: science graphics are usually either static or animated without sources. Five principles follow (real structures, a source for every number, honest confidence, motion with a reason, education only), then installation, example prompts and a gallery of live figures.
