Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotation readOnlyHint=true already establishes the safe read-only nature. The description adds no additional behavioral context, such as whether all import lists are returned, performance considerations, or response structure. With no parameters, there isn't much to disclose, but the description still fails to clarify scope.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
