Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but offers minimal behavioral insight. It confirms this is a deletion operation (destructive), but doesn't address critical aspects like permissions needed, whether deletions are permanent/reversible, rate limits, error handling for partial failures, or what happens to associated data. For a batch destructive tool, this is inadequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
