Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare this as a non-readonly, non-idempotent, non-destructive, open-world write, so the safety profile is covered. The description adds nothing at all — it does not say what a created preset contains, whether it starts as a draft, whether a body is required, or what happens on repeat calls despite idempotentHint=false.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
