WHAT IT DOES

WHY IT NEEDS A POLICY

Why add_tag_to_task needs a policy

This tool creates or modifies task metadata by attaching a tag, which is a reversible write operation. It does not delete data (not Destructive), does not execute arbitrary code (not Execute), does not move money (not Financial), and does not retrieve-only (not Read).

From the tool's definition Tool name 'add_tag_to_task' and description 'Adds existing tag to task' indicates a modification operation. The verb 'Adds' explicitly shows data is being changed/created (a tag association), and this is reversible (the tag can be removed).
