Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided. The description mentions return type (JSON string) and error handling (Chinese error messages), but does not disclose read-only nature, idempotency, or potential side effects. For a listing tool with no annotations, more behavioral context is expected.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
