I vibe-slopped a small and local forms application for my family. I explicitly mentioned that fact to the LLM.

Yet, I removed 2/3s of the code, because it triple-checked that every file really existed and was valid, that the input form was less than a million bytes in size, that there were propper HTTP status codes for everything, that every possible error from reading data was eagerly checked and caught, and so on.

Like come on, three people will ever look at it. So keep it small and tidy so I can understand it better!
