Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden. It implies a read-only aggregate but says nothing about authentication requirements, whether values are live or cached, or what scope (user/workspace) the aggregates cover. For a dashboard endpoint with zero annotation coverage this is thin.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
