Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden. 'Revoke' implies the token is invalidated, but the description does not disclose whether authentication is required, whether the action is irreversible, whether it takes effect immediately, or what happens on repeated calls. For a destructive operation, this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
