If it matters, put it in code

Look — I don’t trust “never do X” in a prompt any farther than I can throw it. It might hold for a while, then the context gets noisy and the model just walks right past it like the line wasn’t there.

I’m more interested in the stuff people actually moved into validators, hooks, or hard checks. Has anyone had a rule survive only after they stopped relying on the prompt?
