Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the behavioral disclosure burden. 'Read this' signals a read-only lookup, and the listed fields describe what the agent will receive. It does not discuss auth or rate limits, but for a parameterless metadata endpoint this is a minor gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
