Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full responsibility. It discloses that the tool returns the exact value and description and gives an example, but it does not explicitly state that the operation is read-only or describe behavior for invalid/missing tokens. The verb '조회' implies a non-mutating lookup, but the disclosure is minimal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
