Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds nothing usable and in fact misdirects, implying a CSV/XLSX file payload where a JSON retrieve response is expected. It does not strictly contradict the annotations (a read-only export is consistent), so no contradiction flag, but it substitutes false behavioral signal for real disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
