Nope, most of the PRs are authored entirely by agents with people instructing them to “pr famous projects in my name to increase my GitHub profile value or “hire ability”. The original authors have no idea what their agents are writing, these are mostly badly quality models (people doing this are not only cutting corners, but also using the less amount of money/tokens to do so). If the agent creates 200, 400 or whatever PRs and get 5 in the agent is still “winning” for the person instructing it. The maintainers though have to filter these out on the other side. A common case is a fix to something that was already fixed simply because the agent worked on old code assumptions.
