It usually builds throw away tooling. It’s not polished or user friendly. If you give it a directive to preserve and document tooling it will reuse it later and potentially improve it.

Mine's never said such a thing, that's a good idea though.

I notice with mine that it only matches my level, by default it's a dump slop generator, then if I start asking, "shouldn't you test this, shouldn't you refactor that" suddenly it 'remembers' all kinds of software engineering knowledge.
