Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations are entirely absent, so the description carries the full behavioral disclosure burden. The verb '조회' (retrieve) implies a read-only operation, and the description explicitly says it returns aggregated counts, giving some transparency. However, it does not disclose any other behavioral traits such as response format, pagination behavior beyond the parameter default, or resource intensity. For a simple read tool, this is adequate but not rich, hence a mid-level score.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
