Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint, so the safety profile is fully covered structurally. The description adds nothing beyond that – it does not mention 404 handling for unknown ids, auth requirements, or what a status label record contains, making it a restatement of the title.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
