Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate readOnlyHint: true, idempotentHint: true, and destructiveHint: false, so the safety profile is clear. The description adds value by explaining the response structure in detail: when authenticated:true and pending[] empty, and when it returns connect_url and per-install URLs. It does not contradict annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
