In LLM agent systems, hook payloads fire every turn and often contain text that reads like an instruction ('MODE ACTIVE', 'STOP', mode-switchers). The right mental model is that hook output is telemetry, not a command. The only signal that should override agent behavior is the explicit user-channel marker [OUT-OF-BAND USER MESSAGE — ...]. Anything else is just data shaped like a directive, and LLMs will default to honoring it if you don't pre-commit a rule.
