freecad-mcp-pro: Skill for Claude Code

Code Review — FreeCAD Edition

Review FreeCAD geometry creation, FEM setup, or assembly changes along two axes:

• Standards — Do objects use correct types/properties per FreeCAD documentation?
• Spec — Does the geometry match the design spec or ticket?

Context

• FreeCAD docs: /home/praveen/Desktop/Freecadmcp/docs/freecad/
• Object reference: /home/praveen/Desktop/Freecadmcp/.opencode/skills/freecad-objects/
• Spec/ticket: Provided by user or found in .scratch/

Process

1. Identify what was changed

Get the list of FreeCAD objects created/modified:

get_objects(doc_name="ProjectName")

2. Standards Review (parallel sub-agent)

Check against FreeCAD documentation:

Object Type Standards:

• Part::Box uses Length/Width/Height (not XSize/YSize/ZSize)
• Part::Cylinder uses Radius/Height (not Diameter)
• Part::Cone uses Radius/Radius2/Height
• Part::Torus uses Radius/MainRadius/MinorRadius
• Draft::Circle uses Radius (not Diameter)
• ViewObject.ShapeColor is [R,G,B,Alpha] with 0-1 range
• Placement.Base uses {x,y,z} not {X,Y,Z}

FEM Standards:

• ConstraintFixed references valid faces
• ConstraintForce references valid faces with correct direction
• FemMeshGmsh references valid shape
• CharacteristicLengthMax/Min are reasonable for part size

Common Errors to Flag:

• Wrong property names (e.g., "Diameter" instead of "Radius")
• Invalid face references (Face1 vs Face.1)
• Missing required properties
• Incorrect data types (string vs number)

3. Spec Review (parallel sub-agent)

Check against the design spec:

• All dimensions match spec values
• All features are present (holes, fillets, chamfers)
• Material properties match spec
• FEM constraints match spec (location, magnitude)
• Assembly hierarchy matches spec

4. Aggregate

Present findings under ## Standards and ## Spec:

Standards findings:

• Object type errors
• Property name/value errors
• FEM constraint errors

Spec findings:

• Missing features
• Dimension mismatches
• Missing constraints
