Open source agent harness letting Codex or Claude Code generate source-controlled CAD models exportable as STEP, STL, 3MF, DXF, GLB, and URDF.
Key Takeaways
Bundles four skill sets: CAD, URDF robot description, Robot Motion (ROS 2/MoveIt), and manufacturing preflight, each usable standalone.
Exports cover mechanical formats (STEP, STL, 3MF, DXF) and robotics formats (URDF, GLB with topology data), making it useful across hardware and robotics workflows.
@cad[...] geometry references give agents stable handles for precise follow-up edits without re-describing geometry from scratch.
CAD Explorer runs fully local on port 4178 with no hosted backend; requires Python 3.11 venv and Node.
Workflow is commit-friendly: source files are edited first, artifacts regenerated explicitly, then committed together for reproducible history.
Hacker News Comment Review
Commenters flag that LLMs remain weak at spatial reasoning versus diffusion models, limiting CAD generation quality regardless of harness quality; zoo.dev cited as a deeper prior effort on the same problem.
No substantive technical discussion of the repo itself in the thread yet.
