+`ai/_AGENTS.md` owns the jj rules; reach for the `jj` skill before free-handing commands. Its commit-granularity rules are looser here — there's nothing to build and no test suite to bisect, so related config changes can share a commit rather than being split into one logical unit each. Still split changes that have nothing to do with each other.
