Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description claims to 'Schedule a new backup', suggesting each call creates a new backup. This contradicts the idempotentHint: true annotation, which implies repeated calls have the same effect. Additionally, the description adds 'runs in the background' but doesn't clarify idempotency behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
