Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the transparency burden. It discloses the external network source and the 7-day cache policy, adding useful behavioral context. However, it does not mention potential latency, failure modes, or the effect on the local dataset, leaving some behavioral ambiguity.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
