Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the behavioral burden. 'List' reasonably implies a read-only operation, and the description reveals that results include use cases and one-time-purchase links. However, it does not mention pagination, data freshness, or any side effects, leaving some behavioral detail undisclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
