Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It discloses the soft-delete nature and the 404 behavior, which are key behavioral traits. It does not mention reversibility, authorization, or side effects on analytics, but it provides meaningful context beyond the name.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
