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 action ('Check') but doesn't describe what 'health' entails (e.g., uptime, performance metrics, error rates), how the check is performed, whether it requires authentication, or what the response format might be. This leaves significant gaps for a tool with zero annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
