Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses that counts are 'approximate', which hints at estimation or caching, but it does not mention permissions, rate limits, or error behavior. This adds some value beyond the tool name but 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.
