An AGENTS.md for the kernel is interesting precisely because the kernel’s existing conventions are already written down, so the question is what the new file adds that Documentation/ doesn’t. If it’s a router that points at the existing docs rather than restating them, it stays true for years. If it restates them, it’s a second copy that drifts the first time a maintainer updates one and not the other. So what goes in it that isn’t already in Documentation/process?
