alt Hacker News>> He catches stuff in code review that I didn’t catch, and claude/copilot didn’t catch.
This, I find completely unbelievable. Because we had (emphasis on had) seasoned engineers on the team who similarly eschewed AI tools and insisted on doing everything by hand in the manner you describe, well after the rest of the team adopted AI. Yet when it came to code reviews, even in parts of the codebase they were familiar with, the bugs they found often came down to nits, bike-shedding and opinion-based feedback (that they usually tried to frame as objective fact). They would also disagree with almost every AI finding, arguing that it was an unrealistic scenario or an edge case not worth worrying about.
Fundamentally, I don't think humans are going to be capable of providing high quality feedback on PRs authored by AI agents unless those PRs are fairly small in lines of code and volume. It's just way too much information and context for one person to keep in their head. I read a statistic that said the average lines of code a senior engineer can read and provide good feedback on is about 400 per hour, and that number goes down the more time they spend doing code reviews. So, to anyone who insists on trying to keep up with AI, I say: good luck.

You both have anecdotes. Anecdotes don’t “cancel” each other out.
Here’s a third one. In some of the code reviews I’ve encountered that AI gives a lot of feedback, it’s just providing noise. Things that should be ignored or when following the feedback causes more harm which requires more token to “fix” later on. That can also happen. Sometimes the thing it spits out goes against the common sense, and sometimes it works very well.

This I agree with, for a different reason. It’s like trying to swim in a sea of honey and trash mix. It’s exhausting.
Claude's code review skill, in particular, can find some good stuff. But it has some big blind spots around certain types of code. And it likes to come up with a lot of nits too—I think it's really really trained to try to always find between 2 and 8 things or somesuch. Good news is that it is very receptive to "nah" on the bikeshed ones and doesn't stick with them, but will stick with big issues. It'll probably bring up a few more nits though that it didn't bring up the first time!
But I can completely believe that someone who knows the code by heart would have a better signal to noise ratio on their reviews.
I'm trying to find the sweet spot because I've found some NASTY bugs Claude missed, and also had Claude find some nasty ones for me. And this is in codebases with tens-of-thousands of AI-generated lines of code + AI-driven reviews. So I want to bring both to the table.
The existence of some of these major "oh man that changes a lot of our assumptions" bugs that were only found because someone poked on the agent and said "I don't think you're paying enough attention to this" justifies that, IME.
And the better you are at pointing the agent at the truly-important parts, the better the agent's gonna be at finding shit you missed.
