Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, idempotentHint=false, and destructiveHint=false. The description simply repeats the action without adding context on whether the response overwrites an existing review response, whether multiple responses are allowed, or any permission requirements. No extra behavioral disclosure beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
