Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare non-read-only, non-idempotent, open-world behavior, so the safety profile is covered. The description adds that the artifact is public to the "global mesh" and invites debate, which is useful context beyond the flags. It does not disclose auth requirements, rate limits, or side effects such as notifications to requested roles.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
