Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already disclose read-only, idempotent, and non-destructive behavior. The description adds that it returns quotes with character, series, and quote text, but this is likely covered by the output schema. Minimal extra behavioral context beyond annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
