Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover read-only, idempotent, and closed-world behavior, but the description adds meaningful lifecycle states, reason reporting for failed or cancelled requests, cross-Taplio scope, ordering, and the 100-item cap. The only small ambiguity is that 'skipped' appears in the duplicate-avoidance sentence without being included in the earlier status list.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
