Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It implicitly conveys a read-only operation via 'Get' and notes 'real-time' plus network-wide scope, but it does not state explicit safety (e.g., read-only) or potential caveats like caching or authentication. This is adequate for a simple analytics fetch but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
