Imo slop debt stops at the source. Sure when you finally get everything working it's a huge pain and the last thing you want to do, but you have to continue working until that pull request is crisp, minimal, and has razor sharp clarity.

Ultimately it has to be well-written, well-engineered code, and LLMs are good at working with you on getting to that state. But when you finally get all the cases working, you have another significant step in getting it to a reviewable, acceptable request. And this means you need to have a quick, understandable, effective test suite.

Any other way and you're going to throw your codebase, product, and culture in the trash bin.
