Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotation readOnlyHint=true already signals a read operation, and the description's 'List' is consistent with that, so there is no contradiction. However, the description adds no behavioral detail beyond the annotation—it does not mention pagination, filtering, or the structure of the returned list, which would be valuable context for a tool with minimal annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
