*Talking to github AI (Claude Opus 4.5) with VS Code plugin.
**Created first draft of LifeTrac v25 machine design using purely AI prompts for OpenSCAD.
**Process is render openscad, look for errors, tell AI about errors, apply changes, re-render and repeat.
**Claud 4.5 seems to be a bit better than GPT 5.1 Codex Max in understanding physical world of openscad
