Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description carries full burden. It discloses read-only behavior, empty response if no annotation, and contextual background about grandMA2 Info keyword. Could mention error cases like non-existent group, but overall transparent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
