Anything in your working directory or shell can end up in a coding agent's transcript, and transcripts get synced and shared. Make what the agent reads useless to anyone else.

An AGENTS.md file has a reader that acts on what it says. That changes what belongs in it: commands that work, the traps, what never to touch, and very little else.

AI makes you faster at what you already understand. The judgment you use to steer it and check its work comes from doing hard things yourself, so keep a few of them on purpose.

AI made tools cheap to build. It didn't make them cheap to own, and owning is where the cost always was.

Writing code isn't the slow part anymore. Keeping the repo straight and cleaning up for review is, and that's why I switched to Jujutsu (jj).
