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 mentions the output includes overall stats, top stale nodes, and data source freshness, but does not specify side effects, idempotency, or access requirements. The presence of an output schema partially compensates, making this minimal but adequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
