The purpose of this repo (harness and skills) is really to just give the models more direct tools to generate and inspect STEP files. It basically generates a topology sidecar for every STEP file that can be used to quickly read the BREP (faces/edges/vertexes) without loading in the full STEP.
There's also a bunch of work going into the SKILL.md to plan for more complex parts (this is mostly a stop gap while the models don't have amazing spatial reasoning).
I appreciate that effort, seeing Claude start to prototype physical objects that can get mass-produced is unbelievable but wow it uses up tokens like crazy.
I'm using Opus 4.7 w/ the 1M context option on the vibrating mesh nebulizer repo and have hit compacting pretty often which is a restart-the-conversation flag for me on relatively small OpenSCAD files like the adapters and enclosures here which are like 10-40kb: https://github.com/dmchaledev/VibratingMeshNebulizerControll...
