cad-suite

A Claude Code plugin that bundles three skills for parametric CAD, robot-description, and robot-motion work, plus the CAD Explorer viewer.

The skills come from text-to-cad; this repository repackages them as an installable Claude Code plugin so they can be used in any project without cloning the harness.

What's inside

Skill	Purpose
cad	STEP-first build123d/Python CAD generation, inspection, and @cad[...] references
urdf	URDF generation, joint/link validation, mesh references
robot-motion	ROS 2 / MoveIt 2 inverse kinematics, path planning, motion server tooling

The CAD skill ships with the CAD Explorer Vite/React viewer under skills/cad/explorer/ for browsing generated geometry.

Install

Add the marketplace once:

/plugin marketplace add https://github.com/algoryn-nl/cad-suite

Then install the plugin:

/plugin install cad-suite

First-run setup

After installing, run the bundled setup command from inside the project where you want to author CAD:

/cad-suite:setup

This creates .venv/ in your project, installs the Python CAD dependencies, optionally installs URDF dependencies, and runs npm install for the CAD Explorer. Robot-motion (ROS 2 / MoveIt) is not auto-installed — see skills/robot-motion/SKILL.md.

Manual setup

If you'd rather install dependencies by hand:

# Python deps (CAD)
python3.11 -m venv .venv
./.venv/bin/pip install --upgrade pip
./.venv/bin/pip install -r ${CLAUDE_PLUGIN_ROOT}/skills/cad/requirements.txt

# Optional: URDF
./.venv/bin/pip install -r ${CLAUDE_PLUGIN_ROOT}/skills/urdf/requirements.txt

# CAD Explorer (Node)
npm --prefix ${CLAUDE_PLUGIN_ROOT}/skills/cad/explorer install

Launch CAD Explorer

npm --prefix ${CLAUDE_PLUGIN_ROOT}/skills/cad/explorer run dev

Then open http://localhost:4178.

For multi-project workflows that share a single Explorer:

npm --prefix ${CLAUDE_PLUGIN_ROOT}/skills/cad/explorer run dev:ensure -- \
  --file STEP/sample_part.step
