Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide read-only, idempotent, open-world, and non-destructive hints. The description adds value by specifying the data source (Launch Library 2), default result count, and the exact fields returned, going beyond the annotations. No contradictions found.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
