Mechanical-AI-Skill

Mechanical-AI-Skill is an AI mechanical engineering review skill, not a CAD copilot or a geometry generator. It is a structured engineering-review layer that lets an AI agent, such as Claude Code, Codex or Cursor, reason about a mechanical assembly: upload a STEP assembly, understand the design, review the engineering risks, and generate a report.

On a STEP file alone, with no SolidWorks and no geometry kernel, the Community Edition reads structure and runs approximate geometry checks: an executive review with a risk score, a name-level BOM with true quantities from assembly instance counts, assembly structure, interference, DFM and DFA checks, and mechanical diagnostics. With SolidWorks it runs the production checks. Reports come out as PDF or HTML.

The README's worked example is a real 39 MB SolidWorks-exported STEP of a dual-station robotic welding cell: 142 unique parts, 357 instances, assembly depth 4, with detected mechanisms, vendors and categories, a risk score of 88 out of 100, and four findings. The README states every figure in that example is the actual output and nothing is invented.
