Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description conveys a read-only operation and adds the behavioral detail that statistics are broken down per state, which goes beyond the tool's name. However, it does not explain what states are included, whether the instruction must be in a particular status, or what the response structure looks like. With no annotations available, the description carries the full burden and leaves these gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
