Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states this is a read operation ('확인합니다' - check/verify) which implies non-destructive behavior. However, it doesn't disclose important behavioral traits like whether this requires authentication, rate limits, what format the statistics are returned in, or whether it's real-time vs cached data. For a status tool with zero annotation coverage, this leaves significant gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
