"CLAUDE.md is a 'request' to the model, but a hook is a script executed before every tool call. If it returns exit 2, that tool call is physically blocked. No matter how much the model wants to execute it, it cannot move. It's the difference between a 'sign' and a 'wall'. A sign can be ignored, but a wall cannot be passed."
