SolidworksMCP-python: Skill for Claude Code

Feature-Tree Reconstruction

Use this skill when the original model is available and appearance-first guessing would be risky.

Objective

Produce a safe, evidence-backed reconstruction workflow that starts from model inspection and only executes after the family and first-feature strategy are approved.

Workflow

1. Inspect before planning:
   • open_model
   • get_model_info
   • list_features(include_suppressed=True)
   • get_mass_properties
   • classify_feature_tree
2. Classify feature family and confidence:
   • revolve, extrude, sheet_metal, advanced_solid, assembly, drawing, unknown
3. Delegate by family:
   • sheet_metal and unsupported advanced families: VBA-aware reconstruction path
   • simple part families: direct MCP checkpoint plan
   • assembly: component-first decomposition, part-level reconstruction per component
4. Retrieve supporting evidence before execution:
   • local worked examples
   • tool-catalog pages
   • recent error/remediation history
5. Execute conservatively:
   • propose 3-6 checkpoint steps only
   • require human approval before each irreversible step
6. Verify and store:
   • capture resulting feature-family alignment
   • compare mass properties and key dimensions
   • log failures and remediation for future runs

Output Contract

Always return:

• family
• confidence (high/medium/low)
• evidence (top items used)
• warnings (contradictions, missing evidence)
• recommended_workflow
• checkpoint_plan (3-6 steps)
• requires_human_confirmation (true/false)

Guardrails

• Never reconstruct from silhouette only when the source model is available.
• Never produce a monolithic 20-step build plan before family acceptance.
• Do not continue execution when confidence is low and contradictory evidence exists.
• If family is unknown, force additional inspection and user clarification before build.
• For sheet metal and unsupported operations, route to VBA-aware planning instead of guessing direct tool calls.
