WHY IT NEEDS A POLICY

Why mindmap_persona_set needs a policy

This tool creates or modifies user preferences durably in persistent storage. While reversible (preferences can be changed or deleted), it writes configuration state that affects future AI agent behavior. The incomplete description suggests it sets persona/preference data. Severity is medium because misuse could cause inconvenient behavior changes across sessions, but no data loss or external effects occur.

From the tool's definition Tool name 'mindmap_persona_set' and description 'Save a durable preference' indicate creation or modification of user preference data that persists across sessions.
