Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description bears full responsibility. It states the tool returns a JSON string and raises exceptions with Chinese error messages, and mentions pagination and custom output fields. However, it does not disclose whether the operation is read-only (though likely safe) or any side effects. This is adequate but leaves some transparency gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
