I just added a chapter which touches on that: https://simonwillison.net/guides/agentic-engineering-pattern...

Yeah, I think that's one of the biggest anti-patterns right now: dumping thousands of lines of agent-generated code on your team to review, which effectively delegates the real work to other people.

> Code review should be mandatory and reviewers should ask big PRs to be broken up

Always, even before all this madness. It sounds more like a function of these teams CR process rather than agents writing the code. Sometimes super large prs are necessary and I've always requested a 30 minute meeting to discuss.

I don't see this as an issue, just noise. Reduce the PR footprint. If not possible meet with the engineer(s)
