Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description carries the full burden for behavioral disclosure. It states what is checked (health and version), but does not mention response format, potential errors, or whether any state is changed. Since it's likely a read-only health check, the description is adequate but lacks depth.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
