I use openscad vibe coding quite a bit. It tends to fall down beyond extremely simple examples, though. Error categories I've encountered if you want to build better rails: (1) forgetting axis orientations after multiple layers of rotate() (2) center=true presence ignored resulting in mistaken geometry (3) inconsistent naming (4) insufficiently verbose naming (5) 3D printing tolerances (6) lack of validation (7) shared faces causing rendering issues

I would suggest that every stage has the following basic checks: (A) If it's a 'substract' type operation, ensure the resulting shape has less volume than the original shape (B) Ensure no 'subtract' results in zero volume shape (C) Ensure no 'shared faces' exist (D) Ensure output is consistent with requisite axes (eg. render an elevation in orthographic and know which way is up/down in profile so that relative terms can be quantitatively verified in the rendering) (E) Name everything with a semantic tree that is updated properly instead of hacked upon until it becomes illogical and incoherent

This would go a huge way to fixing the main issues encountered so far.
