Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It does disclose that this is a '공개 조회' (public query/read-only) operation, which is useful. However, it does not explicitly state that there are no side effects, nor does it clarify ambiguity about whether it is restricted to the calling agent. The return summary is mentioned, adding some transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
