CadQuery Code-CAD

Installation

1. 1
   Make sure Claude is on your device and in your terminal.

   Skills load from ~/.claude/skills/ when Claude Code starts up — so you need it on your machine first. If you don't have it yet, install it once with the command below, then run claude in any terminal to verify.

   One-time setup

   Copy

   npm i -g @anthropic-ai/claude-code

   Already have it? Skip ahead.

2. 2
   Paste into Claude Code or into your terminal.

   This downloads the skill into ~/.claude/skills/cad-cadquery-python/SKILL.md.

3. 3
   Restart Claude Code.

   Quit and reopen Claude Code (or any other agent that loads from ~/.claude/skills/). New skills are picked up on startup.

4. 4
   Just ask Claude.

   Skills auto-activate when your request matches the skill's description — no slash command needed. Trigger phrases live in the skill's own frontmatter; you can read them in the “What this skill does” section above.

When Claude uses it

Write parametric 3D models in Python using CadQuery 2.x. Use when the user wants a CAD model defined in Python, code-CAD, programmable parts, brep/STEP output, or a part they can drop into a build script or generative pipeline. Produces solids that export cleanly to STEP, STL, and 3MF — and snaps onto fasteners, sweeps, lofts, and shells you'd struggle to do in OpenSCAD.
