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. While 'Delete' clearly indicates a destructive operation, the description lacks critical details: whether deletions are permanent or reversible, what permissions are required, rate limits, error handling for partial failures, or what happens to associated data. For a destructive batch operation with zero annotation coverage, 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.
