Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full responsibility. It describes the return format (JSON), error handling (Chinese error messages), and possible empty responses with reasons. It does not explicitly state read-only behavior or side effects, but the description implies a safe read operation. This meets basic transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
