Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It does state the return fields, which is useful, but it does not disclose whether the operation is read-only, whether there are any side effects, authentication requirements, or pagination behavior. The mention of '캐시 보유 여부 반환' (returns cache availability) adds a minor behavioral detail, but overall the description is sparse.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
