I've found that the thing that made is really click for me was having reusable rules (each agent accepts these differently) that help tell it patterns and structure you want.

I have ones that describe what kinds of functions get unit vs integration tests, how to structure them, and the general kinds of test cases to check for (they love writing way too many tests IME). It has reduced the back and forth I have with the LLM telling it to correct something.

Usually the first time it does something I don't like, I have it correct it. Once it's in a satisfactory state, I tell it to write a Cursor rule describing the situation BRIEFLY (it gets way to verbose by default) and how to structure things.

That has made writing LLM code so much more enjoyable for me.
