I've been making Rapidcam.app. The file schema is open source and json format designed for AI to be able to write directly. The format is also designed for version control. The focus is 2.5D parametric mostly for 3 or 4 axis CNC.

Interesting. I think if AI is useful at all it will be useful in a partly-GUI context, so I am encouraged.

At a glance, not sure how you're approaching constraints, and what luck you've had with getting language models to be able to juggle them?
