Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true, openWorldHint=true, idempotentHint=false, and readOnlyHint=false, so the safety profile is covered. However the description adds nothing beyond that: it does not say the body fields are required, what auth or permissions are needed, or that creation is non-idempotent and will produce duplicates if retried.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
