WHY IT NEEDS A POLICY

Why addTagToNote needs a policy

This tool creates a relationship between a tag and a note, modifying the note's metadata. It is reversible (tags can be removed via complementary operations like deleteTag or by updating the note), making it a Write rather than Destructive action.

From the tool's definition Tool name 'addTagToNote' and description 'Add tag to note' indicate a modification operation that associates a tag with an existing note, which is a reversible write operation.
