Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already establish readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is covered. The description adds useful ordering behavior ('newest first') and recency framing ('Recently disclosed'), but it does not elaborate on pagination, data freshness limits, or any other operational nuances beyond what annotations and schema already convey.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
