Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already mark this as read-only and idempotent, but the description adds behavioral detail beyond those hints: it explains the `authenticated:true` and `pending[]` condition, and the `connect_url` returned when credentials are missing. This is useful context not inferable from annotations alone.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
