WHY IT NEEDS A POLICY

Why manage_topics needs a policy

This tool modifies user preferences reversibly—topic preferences can be updated, added, or removed without permanent data loss or external side effects. It does not delete data irreversibly (would be Destructive), execute code (Execute), or move funds (Financial). The Write category is most appropriate as it creates or modifies data in a reversible manner.

From the tool's definition Tool name 'manage_topics' combined with description 'Manage research topic preferences' indicates creation or modification of user preferences/configuration data. The verb 'manage' in this context implies both read and write operations on topic settings.
