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. While 'Delete' implies a destructive mutation, the description doesn't mention critical aspects like 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, this represents significant gaps in behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
