Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, destructiveHint, and idempotentHint, so the safety profile is clear. The description adds no extra behavioral context (e.g., pagination, limit behavior, response structure). It meets the minimal bar but does not leverage the opportunity to add value.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
