Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses the irreversible nature, the effect on new sales, the requirement for user confirmation, and the outcome for prior purchasers. This is comprehensive behavioral disclosure for a destructive operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
