baidu_gesture

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

No annotations are provided, and the description only mentions pricing. It does not disclose behavioral traits such as whether the tool is read-only, any side effects, or what permissions are needed. The agent lacks information about the tool's operational behavior.

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 extremely concise: a single line with category tag, name, and pricing. It is front-loaded and efficient, but the brevity comes at the expense of essential details, which is acceptable given the simplicity of the tool.

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?

With only one parameter, no output schema, and no annotations, the description should provide more context about what the tool returns or how to interpret results. The current description is incomplete for an agent to confidently use the tool without additional assumptions.

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 schema has 100% coverage for the single parameter 'image', describing it as '手势图片URL'. The tool description adds no additional meaning beyond this, so the score is at baseline.

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 states '手势识别' (gesture recognition) and the input schema expects an image URL, making it clear the tool recognizes gestures from images. However, it lacks a verb like 'Recognize' and does not specify what output to expect, which could reduce clarity about the specific task.

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 provides no guidance on when to use this tool versus sibling tools like baidu_object_detect or baidu_face_detect. It only includes pricing information, which does not help the agent decide contextually.

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