Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full behavioral burden. It only conveys a daily time grain and gives no information about return shape, read-only behavior, pagination, or limitations. The agent is left to infer even that this is a retrieval operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
