Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the burden of behavioral disclosure. It only states 'Delete a backup', implying destruction but without clarifying irreversibility, required permissions, or potential side effects. The presence of an output schema is not mentioned, and the description falls short of informing the agent of the permanent nature of the action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
