Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the behavioral disclosure burden. It clearly implies a read-only analytics operation and transparently discloses the 500-row limit with a pagination alternative. However, it does not mention potential rate limits, exact-match requirements, or behavior when no data exists for a page, which would be useful completeness.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
