Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must fully disclose behavioral traits. It mentions that the result includes '全文摘要和详细元数据' (full-text abstract and detailed metadata), but it doesn't clarify read-only nature, error handling, rate limits, or the exact effect of include_full_text. The phrase '全文摘要' is ambiguous, adding to the lack of transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
