Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It discloses the return fields and the ordering (newest first), which is useful. However, it does not mention any limitations, error behavior, or whether the operation is read-only (though implied). Missing details like rate limits, result structure, or handling of empty results reduce transparency, but the basic behavior is described.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
