实时数据/IT资讯热榜

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. The description provides zero information about what this tool actually does - whether it retrieves, creates, modifies, or deletes data; what permissions are required; rate limits; or any other behavioral characteristics. This leaves the agent completely in the dark about how to interact with this 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?

While technically concise (only 7 characters), this description represents under-specification rather than effective conciseness. The single phrase '实时数据/IT资讯热榜' fails to provide any meaningful information about the tool's purpose or usage. True conciseness requires conveying essential information efficiently, not simply being brief.

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 context of 16 similar sibling tools and no annotations or output schema, the description is completely inadequate. It fails to explain what 'IT资讯热榜' means, what data it provides, how it differs from other hot list tools, or what the agent can expect when using it. For a tool that presumably retrieves hot lists from IT information sources, this description provides no useful context.

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 tool has 0 parameters with 100% schema description coverage, so there are no parameters to document. The description doesn't need to compensate for any parameter documentation gaps. While the description doesn't add any parameter information (because there are none), the baseline for a zero-parameter tool with complete schema coverage is appropriately set at 4.

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?

Tautological: description restates name/title.

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 absolutely no guidance about when to use this tool versus its many alternatives. With 16 sibling tools that all appear to be different '热榜' (hot list) tools for various platforms, the description fails to explain what makes 'IT资讯热榜' distinct or when an agent should choose it over similar tools like '知乎热榜' or '微博热搜'.

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