Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without any annotations, the description must disclose behavioral traits. It only says 'Delete', which implies destructiveness, but does not mention whether deletion is permanent, whether confirmation is needed, or any side effects like cascading removal of associated data. This is insufficient 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.
