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. It explains the trash/permanent deletion behavior, which is valuable. However, it lacks critical information such as required permissions, whether deletion is reversible (especially for permanent=true), what happens to linked resources, or error responses. For a destructive operation, this is a significant gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
