Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already establish read-only, idempotent, non-destructive, closed-world behavior, so the safety profile is covered. The description adds useful content scope (published bilingual, full bodies, source/review dates, weekly cutoff) and clarifies that editorial interpretation is not product execution, though it omits auth/rate-limit/pagination behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
