Milkdomeda/ai-mechanical-3dcad-design-agent ? reverse-engineered prompt

Build me a Python tool for mechanical CAD work that helps organize and validate design jobs in a repeatable way. I want a command line app and an MCP server that let me create a workspace, start a new product family, open or resume a design job, and keep all the files, notes, and validation evidence together in the right place. It should support deterministic workflows for mechanical design, include checks for FreeCAD models and standard parts, and store design knowledge in a way that can be learned from later. Please make it work without bundling any language model, but keep it ready for use by a coding agent or another MCP client. Use a local database for structured data, add clear initialization and migration flows for existing workspaces, and make the outputs and diagnostics easy to follow. If you need to, look up the current docs for any FreeCAD or MCP details before wiring it up.
