WHY IT NEEDS A POLICY

Why create_contact_address needs a policy

This tool creates new address records for contacts in an accounting system. While it modifies data, the operation is reversible (addresses can be deleted or updated). The blast radius is medium because incorrect address creation could affect billing, shipping, and communication workflows, but the impact is localized to a single contact's address record and can be corrected.

From the tool's definition Tool name 'create_contact_address' and description 'Create a new address for a contact' indicate a create operation that adds a new data record.
