Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, destructiveHint=false, and openWorldHint=false, so safety is covered. The description adds useful behavioral context about output URL forms: interactiveUrl for human links, recordUrl as a permanent 301 provenance alias, apiUrl/JSONL for JSON, and derivative URL fields. It does not discuss authentication or rate limits, but for this read-only retrieval tool the added URL semantics are substantive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
