Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the core check but does not mention that it is a read-only operation, what the return value looks like (e.g., boolean), or how errors are handled (e.g., invalid chain). For a simple status check, this is a minimal but incomplete disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
