I use AI heavily to review the code too, and it makes it far simpler.
E.g. "show me why <this assumption that is necessary for the code I'm currently staring at> holds" makes it far more pleasant to do reviews. AI code review tooling works well to reduce that burden. Even more so when you have that AI cod review tooling running as part of your agent loop first before you even look at a delivery.
"prove X" is another one - if it can't find a test case that already proves X and resorts to writing code to prove X, you probably need more tests, and now you have one,.
