Moreover this policy is strictly unenforceable because good AI use is indistinguishable from good manual coding. And sometimes even the reverse. I don't believe in coding policies where maintainers need to spot if AI is used or not. I believe in experienced maintainers that are able to tell if a change looks sensible or not.
There's some sensible, easily-judged-by-a-human rules in here. I like the spirit of it and it's well written (I assume by Mitchell, not Claude, given the brevity).
