Every company runs on a culture that tells people how things are done here, and almost none of it is written down because humans absorb it by being around. Your AI absorbs nothing by being around, so the culture has to become a file. - One place to go back to - the way this project runs and why, written where future-you can re-read it. - Readable at session start - the AI opens already knowing how things are done here, not learning it by being corrected. - Queryable across projects - different projects legitimately run differently, and the norms files are where the differences and their reasons live. Mine is a NORMS.md at the root of each workspace. Short lines, each one a way the place works: records are append-only and never edited after the fact, generated files are never hand-touched, every job closes by writing its own record before it ends. Nothing clever. The value is that it is stated once, in one file, instead of living in my head and leaking out one correction at a time. The cross-project part is the bit I did not expect to matter. My YouTube workspace and my drafting system run on different infrastructure and orchestration combinations, each for a reason that was obvious at the time and is forgettable six months later. The norms file is where that reason survives, and because every project has one in the same place, I can ask across all of them how a thing is handled and get the honest spread rather than my memory of it. It grows by being added to, not by being managed. When something goes wrong the same way twice, or I catch myself explaining the same preference again, that becomes a line. I do not gatekeep it or polish it, because a culture file that is a chore to update stops being updated, and then the culture goes back to living in my head. What would the first three lines of yours say?
