Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It mentions it's a GET request, which implies read-only and safe behavior, but it doesn't explicitly state that it has no side effects or that it returns a simple list. For a basic listing operation, the endpoint hint is somewhat informative, but more explicit behavioral disclosure (e.g., 'read-only', 'returns a list of model names') would improve it.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
