Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate a non-read-only, non-open-world operation, and the description adds that it hides the Google News RSS adapter behind a durable product type, which is useful abstraction context. However, it does not disclose side effects such as duplicate handling or whether the query becomes immediately available, leaving some behavioral gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
