Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, conveying a safe read operation. The description adds value by specifying that the tool returns a count and total, which provides some behavioral context. However, no additional disclosures about side effects, auth requirements, or response behavior are made. The description does not contradict annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
