Create, edit, or debug parametric 3D CAD parts in CadQuery (Python) that export to STEP for SolidWorks. Use when the request involves CadQuery, .step/.stl export, or modelling a physical part — enclosure, bracket, PCB, motor mount, cam, gear. Also use when a STEP will not open in CAD, or geometry looks correct in STL but is invalid as a solid. Applies a verification discipline before export and documented OCC pitfalls.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# CadQuery Modeling for Manufacturable CAD This skill turns natural-language part requests into clean, verified, parametric CadQuery code whose STEP output reliably opens in SolidWorks. It encodes hard-won rules from real multi-part product design. ## Core philosophy 1. **Parametric first** — every dimension is a named variable at the top of the file. 2. **Verify before trusting** — a script that printed `[OK]` is NOT proof of success. Always check geometry validity and solid count before declaring done. 3. **Avoid OCC fragility** — prefer simple primitives + boolean operations over fragile chained features. See `references/occ_pitfalls.md`. 4. **One part, one file** — each part is its own `.py` producing its own STEP/STL. Assemblies are done in SolidWorks, not baked into a single STEP. ## Before creating anything: confirm where Files land in whatever directory Claude Code was started in — that is the single thing that determines whether the user finds their STEP later. Before creating a project or the first part, **state the absolute path you are about to write to**, and stop to confirm if it looks wrong: …

How to install
mdr add 0okevino0/claude-cad/cadquery-modeling@sha256:f2cd324f3d144defThe line at the top of this page pins the label git:20260807.73dbe9c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
