Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It reveals that the tool ranks agents by score and provides a reviewer quality summary, which is useful. However, it does not explicitly state that this is a read-only operation, how the threshold parameter affects behavior, or any error/edge-case traits such as handling invalid chain:id pairs.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
