I use a few strategies, but it's mostly the same as if I was mentoring a junior. A lot of my job already involved breaking up big features into small tickets. If the tasks are small enough, juniors and LLMs have an easier time implementing things and I have an easier time reviewing. If there's something I'm really unfamiliar with, it should be in a dedicated function backed by enough tests that my understanding of the implementation isn't required. In fact, LLMs do great with TDD!

If you can't scan the code and see that it's reasonable, that's a smell. The task was too big or its implemented the wrong way. You'd feel bad telling a real person to go back and rewrite it a different way but the LLM has no ego to bruise.

I may have a different perspective because I already do a lot of review, but I think using LLMs means you have to do more of it. What's the excuse for merging code that is "off" in any way? The LLM did it? It takes a short time to review your code, give your feedback to the LLM and put up something actually production ready.

That's why your code needs tests. More tests. If you can't test it, it's wrong and needs to be rewritten.
