Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry behavioral context. It does disclose pagination behavior and parameter range constraints, which is useful. However, it does not explicitly state that this is a read-only operation or describe potential errors or authentication needs, leaving gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
