What remember_deny does on Remember

AI agents use remember_deny to create or update resources in Remember — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Remember environment.

WHY IT NEEDS A POLICY

Why remember_deny needs a policy

This tool modifies the state of a pending action (marking it as denied) and invalidates a token — a reversible write-type operation on workflow/request state. It does not delete data, execute code, or move money.

From the tool's definition Deny a pending action. The request will be marked as denied and the token invalidated.
