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 '实时数据/搜狗热榜' only mentions the type of data (real-time, hot list) but doesn't describe any behavioral traits such as whether it's a read-only operation, potential rate limits, authentication needs, or what the output looks like. For a tool with no annotations, this is a significant gap in transparency.

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 '实时数据/搜狗热榜' is very concise (two Chinese phrases), but it's under-specified rather than efficiently informative. It lacks a clear verb or action, making it feel incomplete rather than well-structured. While brief, it doesn't front-load key information effectively, earning a mediocre score.

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 complexity (a news-fetching tool with no parameters but likely returning data), the description is incomplete. No annotations are provided, and there's no output schema, so the description should explain more about what the tool returns (e.g., list of headlines, timestamps, links). The phrase '实时数据/搜狗热榜' is too vague to provide adequate context for an agent to understand the tool's full scope.

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, and schema description coverage is 100%, so there's no need for the description to explain parameters. The baseline for 0 parameters is 4, as the description doesn't need to compensate for any missing param info. The description doesn't add parameter semantics, but that's acceptable given the lack of parameters.

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 '实时数据/搜狗热榜' translates to 'real-time data/Sogou hot list' which restates the tool name 'sougou_news' rather than specifying what the tool does. It doesn't clearly state a verb+resource action like 'retrieve' or 'fetch', and while it hints at providing hot news from Sogou, it's vague about the actual function. This is essentially a tautology that doesn't distinguish from sibling tools beyond the source name.

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 alternatives. With 16 sibling tools (e.g., baidu_news, weibo_news, zhihu_news) that likely serve similar news-fetching purposes, there's no indication of when Sogou news is preferred, what context it applies to, or any exclusions. This leaves the agent with no usage direction.

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