Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It mentions it retrieves '所有附件列表' (all attachments list) but doesn't disclose behavioral traits like: whether this is paginated (though limit parameter suggests it might be), what format attachments are returned in, whether it requires specific permissions, error conditions, or rate limits. For a retrieval tool with zero annotation coverage, this is inadequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
