Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It discloses return type (JSON string) and error handling (Chinese error messages), but does not mention any side effects, authorization needs, rate limits, or pagination behavior beyond parameter defaults. Adequate but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
