Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden but adds no behavioral context beyond the basic purpose. It does not disclose whether the count is approximate, how large result sets are handled, whether the operation requires specific permissions, or any other operational traits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
