WHY IT NEEDS A POLICY

Why ssl_generate_certificate needs a policy

This tool creates and generates a certificate (a new artifact), which is a reversible write operation. It does not execute arbitrary code, delete data, or move money. However, severity is elevated to 'medium' because misconfigured or fraudulent certificates could enable man-in-the-middle attacks if deployed to intercept HTTPS traffic intended for legitimate domains.

From the tool's definition Tool description states 'Generate server certificate for specific domain' - this creates a new certificate artifact that will be stored/deployed, modifying the proxy's security configuration.
