Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure, and it fails completely. It merely states 'Delete Entity' without mentioning that deletion is destructive, whether it is reversible, what permissions are required, or what side effects may occur.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
