Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden and does so: it discloses that the operation is irreversible, requires confirm=true, affects the single account-level draft, and has elevated risk for EDIT drafts. This is exactly the destructive-operation context an agent needs before calling.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
