Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It mentions the return format ('Markdown格式的搜索结果') but lacks critical behavioral details: whether this is a read-only operation, if it requires authentication, rate limits, error handling, or how results are structured (e.g., pagination). For a search tool with zero annotation coverage, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
