Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses the readonly nature via '[tier: readonly-owner]', the batch limit of 1000, and the underlying POST endpoint. However, it does not mention error handling for invalid IDs, partial results, or response format, which are relevant behavioral aspects.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
