ldraw-nova
Agent tooling that designs buildable LEGO models as LDraw files from a prompt
It is a working example of getting an agent to emit a strict, checkable format and correct its own spatial mistakes, beyond being a fun toy.
ldraw-nova gives a coding agent the specs, part search and rendering tools it needs to design LEGO models in LDraw, the plain-text format fans use for brick CAD. You describe a model and steer it; the agent plans, writes Python that generates the LDraw source, renders, checks collisions and connectors, and revises. Output includes the LDraw file, 3D views, a glTF for Blender and a VR view for Quest 3. Runs in Docker; complex Technic builds cost a few dollars in tokens. AGPL-3.0, by Carlos Antelo.
