That scenario would be annoying but it's not what we have. The agent joins the PR leaves a few comments and responds (with mixed success) to comments. Personally I'd go back to 2020 and never see an LLM again quite happily but that genie is out of the bottle.

Unfortunately, the results speak for themselves and I could probably find dozens of edge cases which the AI code review caught which would have otherwise been missed, probably until production.
