# Industrial Product Design Make the product credible before making the drawing polished. Integrate user tasks, architecture, form, interfaces, motion, CMF, manufacturing, service, and safety into one revision-bound design. ## Portability Contract - Keep the workflow independent of Codex, Claude Code, a CAD vendor, and a specific MCP namespace. - Discover actual tools and capabilities before selecting a modeling route. Never invent a tool call or validation result. - Keep editable native CAD as the design authority. Treat STEP, GLB, STL, renders, PDF, and DXF as derived evidence. - Preserve source files and unrelated geometry. Use document IDs, revisions, configurations, and absolute paths to bind every mutation and output. - Mark missing inputs `TBD`, skipped checks `NOT_EVALUATED`, and assumptions explicitly. Do not turn missing evidence into a pass. ## Skill Boundary - Use this skill upstream for product intent, concept selection, architecture, proportion, interaction, form language, interfaces, configurations, motion, CMF, and design maturity. - Use `mechanical-drafting-gbt` downstream for GB/T views, dimensions, fits, GPS/GD&T, BOMs, manufacturing notes, DRC/DFM, plotting, exchange verification, and release packaging. - Do not duplicate drafting rules here. Do not start release drawings while the product-design gates for the claimed maturity are unresolved. ## Required Workflow 1. **Classify maturity.** Choose `discovery`, `concept`, `design-development`, `enginee
