Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It does disclose return behavior (JSON string containing meeting info) and error behavior (Chinese error messages). However, it lacks context about permissions, rate limits, or the relationship between comt_cd and the committee list, which would be useful for an agent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
