Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate destructiveHint=true and readOnlyHint=false, so the description doesn't need to reiterate that this is a write operation. However, it adds only 'Per-row Status is one of: Accepted, Declined, Exists' and '[DEMO]'—neither of which discloses side effects, idempotency, or failure modes. This is minimal value beyond the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
