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. The word 'permanently' clearly communicates irreversibility, which is a critical behavioral trait for a delete operation. However, it does not disclose potential side effects, required permissions, error behavior, or what happens to associated entities; it only states the core destructive nature.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
