TDQS

D1.9/5.0
Behavior1/5

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

没有提供任何行为信息，如返回相似度分数、是否需要检测到人脸、图像要求等，且没有注释来补充。

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

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

内容非常简短，包含类别和定价，但缺乏核心功能描述，过于省略，没有有效传达工具用途。

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

Completeness1/5

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

对于一个人脸比较工具，没有输出schema，且描述完全未提及输出结果、行为或限制，无法帮助智能体理解其完整功能。

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

Parameters3/5

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

参数schema覆盖100%，描述了图片URL，但描述没有在schema基础上增加额外含义，只提供了无关的定价信息。

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

Purpose3/5

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

描述中包含类别标签[Face]和中文名称'人脸对比'，暗示了比较人脸的功能，但未明确说明是比对两张人脸图像，且与兄弟工具如baidu_face_detect没有区分。

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

Usage Guidelines1/5

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

描述只提供了定价信息，没有说明何时使用该工具、前提条件或替代方案，缺乏使用指导。

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