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. However, the description offers no information about what the tool does (e.g., whether it retrieves, updates, or monitors data), its operational characteristics (e.g., rate limits, authentication needs), or expected outcomes. This leaves the agent completely in the dark about the tool's 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?

While the description is extremely brief ('实时数据/36氪热榜'), this is not true conciseness but rather under-specification. It fails to convey essential information about the tool's function and usage, making it inefficient rather than succinct. The structure doesn't front-load critical details, as it provides no actionable content.

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 is severely incomplete. It doesn't explain what the tool returns (e.g., a list of trending topics from 36Kr), how it behaves, or when to use it. For a tool in a family of similar '热榜' tools, this minimal description fails to provide the necessary context 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 0 parameters with 100% schema description coverage, meaning the schema fully documents the lack of inputs. The description doesn't add any parameter information, which is appropriate since there are no parameters to explain. This meets the baseline expectation for a parameterless tool.

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 no guidance on when to use this tool versus alternatives. It doesn't mention any specific context, prerequisites, or differences from sibling tools like '实时数据/微博热搜' or '实时数据/知乎热榜'. Without any usage instructions, the agent has no basis for selecting this tool over others in the same category.

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

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 behaviorally - whether it fetches, displays, filters, or processes the Bilibili hot list data. It doesn't indicate if this is a read operation, whether it requires authentication, what format the data comes in, or any other behavioral characteristics.

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 (just the tool name repeated), this is under-specification rather than effective conciseness. The description doesn't communicate any useful information in its minimal form. A truly concise description would still convey the tool's purpose and basic operation, which this completely fails to do.

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 tool's apparent purpose (fetching Bilibili hot list data), the lack of annotations, no output schema, and the presence of many similar sibling tools, this description is completely inadequate. It provides no information about what the tool returns, how it behaves, or how it differs from alternatives. For a data-fetching tool in a crowded namespace, this minimal description fails to provide the necessary 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 zero parameters, and the schema description coverage is 100% (though with no parameters, this is trivial). The description doesn't need to explain parameters since there are none. However, it also doesn't mention that this is a parameterless tool, which could be slightly helpful context. Given the zero-parameter baseline, this earns a 4 rather than a perfect 5.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

The tool has 0 parameters, and schema description coverage is 100%, so there are no parameters to document. The description doesn't need to compensate for any parameter gaps, and it appropriately avoids unnecessary parameter details. A baseline score of 4 is applied since no parameter information is required, and the description doesn't misleadingly imply 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?

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 no guidance on when to use this tool versus alternatives. It doesn't mention any context, prerequisites, or differences from sibling tools like '实时数据/知乎热榜' or '实时数据/微博热搜', leaving the agent with no information about selection criteria or appropriate use cases.

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

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. It only states the source ('腾讯新闻热榜'), without describing what the tool does (e.g., returns a list, fetches data), any constraints (e.g., rate limits, authentication needs), or output behavior. This is inadequate for a tool with zero annotation coverage, as it leaves critical behavioral traits unspecified.

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—just the tool name repeated—which could be seen as efficient but results in under-specification. It's front-loaded with the source, but every sentence (in this case, the single phrase) doesn't earn its place by adding value beyond the name. It's brief but lacks substance, making it more sparse than optimally structured.

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 data-fetching tool likely returning hot list items), lack of annotations, and no output schema, the description is incomplete. It doesn't explain what the tool returns (e.g., list of articles, rankings), any behavioral aspects, or usage context. For a tool with siblings and potential data-rich output, this minimal description fails to provide enough information 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 0 parameters, and schema description coverage is 100%, so there's no need for parameter information in the description. The description doesn't add meaning beyond the schema, but with no parameters, the baseline is 4. It appropriately avoids unnecessary parameter details, though it could hint at implicit context if relevant.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

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 no guidance on when to use this tool versus alternatives. Given the sibling tools include other hot lists (e.g., '实时数据/微博热搜' for Weibo, '实时数据/知乎热榜' for Zhihu), there's an implied context of fetching hot lists from different platforms, but no explicit when/when-not instructions or named alternatives are mentioned. This leaves usage unclear beyond the source name.

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

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 but offers none. It doesn't indicate whether this is a read-only operation, if it requires authentication, has rate limits, or what the output might look like. The description is too vague to infer any behavioral traits, failing to compensate for the lack of annotations.

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 a single phrase that restates the tool name, which is overly concise to the point of under-specification. While it lacks wasted words, it fails to provide any meaningful content, making it inefficient in conveying necessary information. Conciseness should not come at the cost of clarity, so this scores low for being too brief without substance.

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 implied by the tool name (likely fetching trending data from a specific source) and the lack of annotations and output schema, the description is severely incomplete. It doesn't explain what the tool does, how to use it, or what to expect in return. For a tool with no parameters but potential behavioral nuances, this description fails to provide the necessary context for effective 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 0 parameters, and the schema description coverage is 100%, meaning there are no parameters to document. The description doesn't need to add parameter semantics in this case. A baseline score of 4 is appropriate as the absence of parameters is adequately handled by the schema, and the description doesn't introduce confusion or unnecessary details.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

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 no guidance on when to use this tool versus its siblings, such as '实时数据/36氪热榜' or '实时数据/知乎热榜'. There is no mention of context, alternatives, or exclusions. This leaves the agent with no information to distinguish between similar tools, making it impossible to make an informed choice based on the description alone.

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

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

With no annotations provided, the description carries full responsibility for behavioral disclosure, but it provides none. It doesn't indicate whether this is a read or write operation, what data format is returned, whether there are rate limits, authentication requirements, or any other behavioral characteristics. The description is completely silent on all operational aspects.

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 (it's just the tool name repeated), this represents under-specification rather than effective brevity. The description fails to provide any useful information that would help an AI agent understand or use the tool. Every sentence should earn its place, but here there's essentially no content to evaluate for structural effectiveness.

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 that this is a data retrieval tool (implied by '实时数据' and '热榜') with no annotations, no output schema, and a completely unhelpful description, the description is severely incomplete. The agent cannot understand what the tool returns, how to interpret results, or how it differs from similar tools. For a tool in a crowded sibling space with no structured metadata, this description provides inadequate 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 zero parameters (schema description coverage is 100%), so there are no parameters requiring semantic explanation. The description doesn't need to compensate for any parameter documentation gaps. A baseline score of 4 is appropriate since the absence of parameters means there's no parameter semantics burden on the description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

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 on when to use this tool versus its many siblings (e.g., 实时数据/微博热搜, 实时数据/知乎热榜). There's no indication of what makes '虎扑步行街热榜' distinct from other hot list tools, nor any context about when this specific platform's data would be needed. The agent receives zero usage direction.

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

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 reveals nothing about what the tool actually does behaviorally—whether it fetches data, subscribes to updates, requires authentication, has rate limits, returns structured data, or has any side effects. It's completely inadequate for understanding the tool's operation.

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 the description is extremely concise (just the tool name repeated), this is under-specification rather than effective conciseness. It doesn't front-load essential information about the tool's purpose or behavior. The single phrase doesn't earn its place by adding value beyond the name itself, making it inefficient for helping an AI agent understand 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?

Given the complexity implied by real-time data fetching (typically involving network calls, potential authentication, and dynamic outputs) and the absence of both annotations and an output schema, the description is severely incomplete. It fails to explain what the tool returns, how it behaves, or any operational constraints, leaving critical gaps for an AI agent to use it correctly.

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 (schema coverage is 100% with an empty object), so there are no parameters to document. The description doesn't need to compensate for any parameter gaps. A baseline score of 4 is appropriate since the schema fully covers the parameter situation (none exist), and the description doesn't contradict or add unnecessary information about parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

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. It doesn't mention any specific context, prerequisites, or differences from sibling tools like '实时数据/虎扑步行街热榜' (which appears to be a similar tool without the 'A' suffix). There's no indication of when this tool is appropriate or when other tools should be used instead.

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