WHY IT NEEDS A POLICY

Why create_signature_request needs a policy

This tool creates (writes) a new signature request artifact for a contract. While this initiates a legal process, the action itself is reversible (the request can be cancelled or modified before signing is complete), distinguishing it from Destructive or Financial categories. It modifies system state by adding a new record, making it a Write operation.

From the tool's definition Tool name is 'create_signature_request' and description states 'Create a new signature request for a contract'. The verb 'create' indicates a reversible write operation that generates a new contract signature request in the AdButler system.
