Not my experience. Most Claude reviews are horrible and if I catch you replying with Claude (any AI really) under your own name you are gonna get two earfulls. Don't get me wrong, if you have an AI bot that I can have a convo with on the PR, sure. But you passing their stuff off as you: do that twice and you're dead to me.
Now, I use it as well to review, just like you mention it pulls it via gh, has all the source to reference and then tells me what it thinks. But it can't be left alone.
Similarly people have been trying to pass root cause analyses off as true and they sound confident but have holes like a good Swiss cheese.
