Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions reading three inputs and 'generating' a lock prompt, but does not disclose whether this mutates state, what the returned prompt structure looks like, whether it consumes credits, or whether it is a safe read-only operation. The cryptic phrase '文本步后付不欠费' is ambiguous and does not meaningfully clarify behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
