After receiving the first LLM-generated pull requests, I have decided to blanket no longer look at those. When studying a PR, I take into account who made it, and if they've previously been careful developers. LLM-generated code I have no idea about, and the amount of scrutiny required is just too much. Because I have to assume you have no idea what you are doing.
@bert_hubert I think mastodon's LLM policy is a good one, iiuc: when you submit a PR you are responsible for it.
If you produce good code with an LLM and review it, that's fine. If you submit LLM generated slop you get ignored.
A good LLM-generated PR should be indistinguishable from a good human one.
