What are your organization's expectations or policies regarding PR size and acceptable AI usage? Even if your organization hasn't set any expectations, what are yours—and have you communicated them to the author?
If expectations have been shared and these changes contradict them, you can quickly close the PR, explain why it's not acceptable, and ask them to redo it.
If you don't have clear guidelines on AI usage or haven't shared your expectations, you'll need to review the PR more carefully. First, verify whether your assumption that it’s a simple service is accurate (although from your description, it sounds like it is). If it is, talk to the author and point out that it's more complicated than necessary. You can also ask if they used AI and warn them about the complexities it can introduce.
