AutoCAD-skills

AutoCAD-skills is a production-minded mechanical CAD skill set for Codex, Claude Code and compatible Agent Skills runners, aligned with GB/T drafting standards. Its premise is that AI-generated CAD can look convincing while still being wrong, so the skill turns common failure modes into explicit gates: parameter authority, requested-versus-actual readback, semantic topology, cross-view proof, physical plausibility boundaries, plot-scale truth and human release authority.

Coverage in the current package, mechanical-drafting-gbt, spans GB/T mechanical drafting with first-angle projection, line hierarchy, dimensions, views and sections, threads, gears, splines, springs and bearings; AutoCAD and MCP use with strict typed requests, atomic staging and handle readback; 2D and 3D parametric parts, assemblies and mechanisms; semantic DRC and DFM; consumer product concepts with safety architecture; and product definition with GPS, GD and T, tolerance stacks, inspection planning and release manifests.

The README states what the repository does not bundle: AutoCAD itself, an MCP server, a CAD kernel, electrical certification or automatic manufacturing approval. Agent-generated manufacturing artifacts remain candidates after human review until an authorized external process approves them.
