What remove_matter_tags does on Smokeball

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

WHY IT NEEDS A POLICY

Why remove_matter_tags needs a policy

Removing a tag from a matter modifies the matter's metadata but is reversible since the tag can be added back. This fits the Write category rather than Destructive, as the tag itself is not deleted and the association can be restored. Misuse could cause organizational/classification issues in matter management.

From the tool's definition 'Remove a tag from a matter' - removing a tag is a reversible modification (tags can be re-added)
