Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It does state this is a read-only operation ('只读列出') and that it doesn't access websites, which provides useful safety-relevant behavioral disclosure. However, it doesn't describe what the returned data looks like, pagination, or error behavior. The read-only nature is the key behavioral trait and it is disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
