WHY IT NEEDS A POLICY

Why record_turn needs a policy

This tool writes/stores conversation data (user prompt and LLM response) into a session context. It creates or modifies session records reversibly and has no execution, destructive, or financial implications. Misuse is limited to storing incorrect or unwanted conversation data, making severity low.

Verdict

record_turn Rate-limited

record_turn stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
