Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, readOnlyHint=false, and idempotentHint=false, so the safety profile is covered structurally. The description adds nothing beyond that: it does not say the deletion is irreversible, whether documents/numbering are released, or what happens if the invoice is confirmed. For a destructive, non-idempotent mutation with zero description-side context, this is a notable gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
