WHY IT NEEDS A POLICY

Why register_secure_prompt needs a policy

This tool creates a new security verification record by registering a prompt. It is a Write operation because it creates new data in the system. Severity is low because registration itself has minimal blast radius—it stores metadata for security scanning without modifying sensitive data, deleting content, executing code, or moving money.
