Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Since no annotations are present, the description carries the behavioral disclosure burden. It does state that the operation is a read/query ('조회한다') of a single detail, which implies it is not destructive and not a list operation. However, it does not describe response shape, error cases, or access implications.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
