WHY IT NEEDS A POLICY

Why create_conversation needs a policy

This tool creates a new conversational video session/interface via the Tavus API. It is a Write operation as it instantiates a new resource. Severity is medium because misuse could result in unauthorized API usage, resource consumption, or cost implications, but it does not directly move money or irreversibly destroy data.
