WHAT IT DOES

What create_certificate does on Domain Suite

WHY IT NEEDS A POLICY

Why create_certificate needs a policy

This tool creates/provisions SSL certificates, which is a reversible write operation that modifies the certificate infrastructure. While it doesn't delete or execute arbitrary code, it creates new cryptographic assets that could be misused to impersonate a domain or intercept traffic if provisioned maliciously.

From the tool's definition Tool name 'create_certificate' and description 'Provision SSL certificate' indicate creation of a new SSL certificate resource.
