It's not for everyone, but I write all the code and then I ask the LLM for a review. It catches something minor thing every single time (out-of-date comments on a function or method, typo, etc.), something that's clear a mistake maybe a third of the time and, occasionally, points out something that looked fine to me but actually won't work because of some other code that I forgot about. I'm a person, I can't remember everything I guess!

I have to say on those occasional times where it finds something that I totally missed or misunderstood, those are for sure the most productive sessions. I find I'm actually working with the model, while I read the code it's pointing me at, and getting a good solution together. Often the model suggest something that's maybe too simple or, weirdly way way too complicated but it's definitely helps me zero in on a decent solution.
