Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It mentions 'full access' which hints at security implications, but it doesn't disclose the sensitive nature of creating an access credential, potential permission requirements, or how the token is returned/stored. This is a significant gap for a mutating tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
