Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate destructiveHint=true and idempotentHint=true, so the description's 'Revoke' aligns with these. However, the description does not add additional behavioral context such as immediate invalidation of the session or effects on the user. With annotations present, a score of 3 is appropriate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
