Reviewing vibe-coded PRs and features has been utterly exhausting over the past few months.
I work on critical, mature software - a small change in behaviour can mean data loss or non-compliance with regulations for our customers. The biggest problem with AI PRs is the sheer amount of churn, extra code and lack of intent with the PRs it generates.
The only way I can describe the latter is that an AI-only PR feels to me like a painting where everything is high detail - and you have to comb over each part before you understand why it's there because so much is superfluous. A well written human PR on the other hand, is painted such that your eye naturally follows the thought process of the author so you can just nod along during the review, as if the solution was obvious.
Also when I'm _using_ the agent; at least 50 percent of my time is spent telling it to stop with it's approach so it doesn't go down a useless rabbit hole and waste tokens.
