Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already establish that this is a read-only, idempotent, non-destructive, closed-world operation. The description adds meaningful state context beyond that: the draft is saved, shown at its current revision, intended for interactive review, and research has not started.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
