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 names the checks performed and the trust-score output, which is helpful. However, it does not explicitly mention that the tool will make network requests to the supplied endpoints, nor does it describe failure/availability behavior or consequences of the check.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
