free_file_search

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

No annotations are provided, and the description lacks behavioral details such as search scope, limitations, or how results are obtained. The return type is vaguely described as 'text content', which is insufficient for a search tool.

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 relatively concise but unstructured, with a blank line and informal 'Args:' section. It front-loads the tool name but could be more streamlined.

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 the presence of many sibling search tools and an output schema (not detailed), the description should clarify what makes file search distinct. It lacks behavior context and does not specify the nature of returned text, making it incomplete for effective selection.

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?

The description provides Chinese explanations for each parameter (e.g., '搜索查询' for query, '搜索语言，默认中文' for language), which adds meaning beyond the schema's type-only definitions. Although allowed values are not specified, the descriptions cover all 5 parameters effectively.

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 explicitly states '文件搜索' (file search) and lists parameters that indicate a search operation. This clearly conveys the tool's purpose and distinguishes it from siblings like free_image_search or free_news_search.

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?

No guidance is provided on when to use this tool versus its siblings. There are no explicit context cues or conditions for use, leaving the AI agent to infer based on the tool name alone.

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