Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare non-readonly, non-destructive, non-idempotent, but do not convey the crucial trait that the output is an unpublished draft. The description supplies that state and the intended review-then-publish lifecycle, adding real behavioral value beyond the annotations, though it omits permission/auth or uniqueness requirements.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
