Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate read-only, idempotent, and non-destructive behavior, so the description does not need to repeat these. However, it adds value by specifying the types of scene information retrieved (e.g., design name, camera info), which provides useful context beyond the annotations. No contradictions with annotations are present.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
