Standing instructions belong on disk, not in your re-briefing every morning.
I was re-explaining the same project context at the start of every session — the stack, the conventions, the do-nots. The fix was a memory file (CLAUDE.md): the standing instructions written down once, that the AI reads on arrival. It's the constitution, not the daily standup.
I tested writing the project's real rules into a CLAUDE.md and watching the AI pick them up cold, without me saying a word.
The on-disk constitution. The AI arrived already knowing the stack and the conventions.
Re-briefing from scratch each session — and note: a written rule still needs a hook to ENFORCE it (that scar got its own field note).
Say it once, to the file. The constitution loads on arrival; you stop being the briefing.
