WHY IT NEEDS A POLICY

Why create_label needs a policy

This tool creates new data (a label) in a reversible manner. It does not execute code, delete data irreversibly, move money, or retrieve existing data. The blast radius is minimal—a mislabeled label can be easily deleted or modified. Severity is low because label creation has no cascading effects on tasks or critical system state.

From the tool's definition Tool name is 'create_label' and description states 'Create a new label with a name and optional color.' The verb 'create' and the operation of adding a new label to the system indicates a write operation.
