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 only states the check but does not describe what the tool returns (e.g., boolean, status object), whether it is read-only, or how it behaves on failure or timeout. This is a significant gap for a diagnostic tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
