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 mentions 'move to trash', which implies the deletion might be reversible, but doesn't clarify if this requires admin permissions, has confirmation prompts, affects related data, or what the response looks like. For a destructive operation, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
