Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the full safety and behavior disclosure. The search-by-value phrasing implies a read-only operation, and 'Returns matching indicator IDs' clarifies the output. However, it lacks details on pagination, rate limits, or behavior when no matches are found. It is minimal but not misleading.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
