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

No annotations are provided, so the description carries the full burden. It mentions 'real-time data' which implies freshness but doesn't disclose behavioral traits like rate limits, authentication needs, data format, or whether it's read-only. For a tool with zero annotation coverage, this leaves significant gaps in understanding how it behaves.

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 very short ('实时数据/搜狗热榜A'), which is concise but under-specified rather than efficiently informative. It's front-loaded but lacks substance, making it more of a label than a helpful description, so it doesn't fully earn its place as a standalone tool explanation.

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 of news data tools and no annotations or output schema, the description is incomplete. It doesn't explain what 'hot list A' entails, the return format, data scope, or how it differs from other tools. For a tool in a crowded sibling set with no structured support, more context is needed to be adequately complete.

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 no parameter information is needed. The description doesn't add any parameter details, which is appropriate here. Baseline is 4 since no parameters exist, and the description doesn't need to compensate for any schema gaps.

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A' states it provides real-time data from Sogou's hot list A, which gives a basic purpose but is vague about what 'hot list A' specifically means. It doesn't clearly distinguish from sibling tools like 'sougou_news' (no suffix) or other news tools, making it a tautology that mostly restates the tool name with minimal added clarity.

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 alternatives. With 16 sibling tools including 'sougou_news' and various other news sources, the description lacks any context about why to choose Sogou's hot list A over other news tools or what specific scenarios it's suited for, offering no usage differentiation.

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