On some of those PRs the AI agent (?) did not really pressure - it reacted promptly with changes and more plausible (hallucinated ?) technobabble why the PR is needed.

It can be quite hard to discern this behavior from a new contributor to the project that might be a domain expert on something you are not. Possibly with the exception of reacting far too quickly & enthusiastically compared to real people that might have a life.
