Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description alone must disclose behavioral traits. It indicates a mutating action ('Archive') but does not explain side effects (e.g., impact on issues, reversibility), required permissions, idempotency, or return value. The endpoint reference adds little 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.
