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 the content categories (时政要闻, 财经动态, etc.) which gives some behavioral context about what types of news to expect, but doesn't disclose important traits like whether this is a read-only operation, rate limits, authentication needs, response format, or freshness of data.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
