Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description contributes nothing further — no indication of what the dashboard payload contains, whether results are user-scoped or permission-filtered, or whether the call is expensive. It does not contradict the annotations, but it adds zero behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
