WHY IT NEEDS A POLICY

Why password_generate_memorable needs a policy

This tool creates new password/secret material, which is a Write operation (creates data reversibly). Severity is high because misuse could generate weak or predictable passwords, or could lead to plaintext password exposure if the returned secret is logged or mishandled by an agent. The 'plaintext for immediate use' requirement elevates risk relative to a standard password generator.

From the tool's definition Tool name 'password_generate' and description 'Generate a memorable passphrase-like password and return it in plaintext' indicates creation of new secret material.
