Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true, indicating a safe, repeatable read operation. The description adds minimal value by implying a GET request, which aligns with the annotations but doesn't provide additional behavioral context (e.g., what 'count' entails, format of the count, or any limitations). No contradiction with annotations exists, but the description doesn't enrich understanding beyond what annotations provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
