WHY IT NEEDS A POLICY

Why jenkins_create_credential needs a policy

Creating credentials (API keys, tokens, certificates) in Jenkins constitutes a Write operation—it creates new authentication material that can be stored and potentially exploited. While not immediately destructive, credential creation is a high-severity action because compromised credentials enable unauthorized access to downstream systems (Firebase, AdMob, Google Play, App Store, as suggested by sibling tools).

From the tool's definition Tool name 'jenkins_create_credential' indicates creation of credentials in Jenkins, a CI/CD automation platform. The 'create' verb and 'credential' object suggest reversible data creation. Description is empty, limiting confidence.
