WHY IT NEEDS A POLICY

Why manage_traffic_rule needs a policy

While the tool includes 'delete' operations, the primary context is managing traffic matching lists—configuration rules rather than irreversible system data. The tool is primarily a Write operation (create/update) with some Destructive potential (delete rules). However, deleting traffic rules is generally reversible through recreation and lacks the finality of destroying critical data or user content.

From the tool's definition Tool description states 'create, update, or delete traffic matching lists' indicating reversible modification and deletion capabilities on network traffic rules.
