baidu_search_tool

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description must fully disclose behavior. It mentions '实时信息' (real-time info) but lacks details on pagination, rate limits, result format, or any destructive/read-only nature. The behavioral description 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.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is brief (two sentences), front-loaded with the action. It could include more detail without becoming verbose, but it is well-structured and avoids redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no annotations, no parameter explanations, and unknown output schema details (though output schema exists), the description is incomplete. Missing behavioral traits, parameter guidance, and result handling information.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema has 2 parameters (query, max_results) with no descriptions (0% coverage). The description does not explain parameter usage, defaults, or constraints. It should compensate but does not, leaving the agent to infer.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb '搜索' (search) and resource '百度网页' (Baidu web pages), with purpose '获取中文互联网的实时信息' (get real-time info from Chinese internet). It distinguishes from siblings: bilibili_search_tool (video) and extract_chinese_page_tool (page extraction).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description lists suitable use cases: '适合查找中文网站、新闻、百科、技术文章等' (suitable for finding Chinese websites, news, encyclopedia, tech articles), providing context on when to use. However, it does not explicitly state when not to use or offer alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
