Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the behavioral burden. It signals a read-only status probe and zero params, but it does not disclose response format, timeout behavior, or how health is determined. For a simple health check, this is minimally adequate but lacks richer behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
