Anatomy skill: what it does and how to install it

What it does. Turns a concept into a physical object whose working is the explanation, such as a dial gauge, a lock or a test rig, drawn as an isometric SVG from dozens of small shaded parts in a framed card with a title, hint and live readout. It ships a drawing kit, eight complete examples, an audit that checks depth order and that no pipe passes through anything, and headless Chrome scripts for screenshots. Figures can add WebGL shaders for fire, water or lamp light, or turn in an optional 3D mode.

When to use it. When you want an explanatory figure for docs, a blog post or a landing page, as standalone HTML or in React and Next.js. It needs Node.js 20.10 or later and Chrome for the checks, and it sizes the job first: a single figure often takes under an hour, a dense hero figure a few hours.
