Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate destructiveHint=true and idempotentHint=true, which the description aligns with by implying session removal. The description adds value by specifying it can target 'current or a specific saved' session, clarifying scope beyond what annotations provide. However, it doesn't detail effects like authentication loss or rate limits, leaving some behavioral aspects uncovered.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
