Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It mentions 'fetches', implying a read operation, but offers no details on side effects, permissions, idempotency, or error behavior. It does not disclose whether the operation is safe or what it might affect. The presence of an output schema partially mitigates return-format expectations but not behavioral traits.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
