Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. It fails to disclose any behavioral traits such as authentication requirements, irreversibility, side effects (e.g., cascading deletes), or rate limits. 'Delete One' offers no behavioral insight beyond the action name.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
