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

With no annotations provided, the description carries the full burden of behavioral disclosure. While '实时数据' implies fresh, current data, it doesn't specify update frequency, rate limits, authentication requirements, or what format the data returns. For a news tool with zero annotation coverage, this leaves significant behavioral gaps.

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 with just two Chinese terms separated by a slash, making it front-loaded and efficient. Every element ('实时数据' and 'B站热榜') earns its place by specifying both the data type and source.

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 lack of annotations and output schema, the description should provide more context about what data is returned, format, limitations, or typical use cases. As a news tool among many alternatives, it needs more differentiation and behavioral context to be complete enough for effective agent use.

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 zero parameters with 100% schema description coverage, so the baseline is 4. The description appropriately doesn't discuss parameters since none exist, and the schema already fully documents this.

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/B站热榜' clearly states the tool provides real-time data from Bilibili's hot list, specifying both the resource (Bilibili hot list) and the data type (real-time). However, it doesn't explicitly distinguish this tool from its many sibling news tools beyond mentioning Bilibili specifically.

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 the 15 other news tools on the server. It doesn't mention alternatives, prerequisites, or specific use cases for Bilibili hot list data versus other news sources.

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