Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full responsibility for behavioral disclosure. It mentions 'connected brokers' but does not explain what happens if none are connected, the meaning of the default 'all', or any limitations. The non-mutating nature is implied by 'Fetch' but never explicitly stated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
