• quake_searchC
  2/5.0
  Behavior1/5

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

  No annotations provided, and the description offers zero behavioral details (e.g., side effects, permissions, limitations). The agent gets no insight beyond the alias indication.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness2/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  Extremely concise (one short sentence) but lacks substance. Every sentence should earn its place; this one provides minimal information, making it under-specified rather than efficiently concise.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness2/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given 9 parameters and an output schema exists, the description fails to explain the tool's overall behavior or how to use it effectively. It is incomplete for a tool with such complexity.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters3/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema has 100% coverage with descriptions for all 9 parameters, so description need not add more. However, it could add context like parameter interplay or defaults, but missing that is acceptable.

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

  Purpose2/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description only states it's a backward-compatible alias for 'quake_service_scroll', but does not explicitly define what the tool does. It relies on the user knowing the other tool's purpose, making it vague.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines2/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  Provides no guidance on when to use this tool versus siblings. Mentioning it's an alias implies it's for backward compatibility, but no explicit usage context or alternatives are given.

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

• quake_service_aggregationC
  2.8/5.0
  Behavior2/5

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

  With no annotations provided, the description carries full burden. It only states the action without disclosing side effects, authentication needs, or data behavior (e.g., whether data is cached or time-bound).

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness3/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is a single sentence, which is concise but lacks structure. It does front-load the action but omits any useful detail.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness2/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  For a tool with 9 parameters and an output schema, the description fails to explain return values, when to use aggregation vs. other searches, or how to interpret results. It is notably incomplete for a complex tool.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters3/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema coverage is 100%, so the schema already documents all parameters. The description adds no additional meaning beyond the tool name and endpoint.

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

  Purpose4/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description clearly states the tool runs a Quake service aggregation query and includes the API endpoint. However, it does not differentiate it from sibling tools like quake_search or quake_aggregation_fields.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines2/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  No guidance on when to use this tool versus alternatives such as quake_search or quake_service_scroll. No context about prerequisites or exclusions.

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

• hunter_enterprise_searchC
  2.9/5.0
  Behavior2/5

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

  With no annotations, the description must fully disclose behavior. It mentions the API endpoint and enterprise scope but omits critical traits like read-only nature, rate limits, or authentication requirements. The description implies a read operation but lacks explicit safety guarantees.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness4/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  Description is concise with one sentence and a field list. It is front-loaded with the action but the list is long and could be formatted more cleanly. Still, it avoids unnecessary verbosity.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness2/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given 9 parameters and no output schema or annotations, the description is too sparse. It does not explain pagination, return format, or behavior of parameters like 'exact_search'. The field list alone is insufficient for an agent to fully understand tool usage.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters3/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema coverage is 100%, so the description adds minimal value beyond the schema. The list of enterprise fields provides context for the 'fields' parameter but is not explained. Baseline is 3 since schema covers parameters.

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

  Purpose4/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  Description clearly states it's a search tool for the Hunter enterprise API and lists enterprise-specific fields, distinguishing it from personal search tools. However, it does not explicitly state the return type or differentiate from other search tools beyond the field list.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines2/5

  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 such as hunter_personal_search or other sibling search tools. The description lacks explicit context for selection.

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

• hunter_personal_batch_createC
  2.9/5.0
  Behavior2/5

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

  No annotations provided, and the description does not disclose behavioral traits such as async nature, rate limits, or what happens after creation (e.g., returns a task ID). It only says 'create' with no further context.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness4/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  A single concise sentence that front-loads the action, though it could benefit from a bit more detail without being verbose.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness2/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given 10 parameters, no output schema, and no annotations, the description is too brief. It fails to explain return values, async behavior, or related tools like hunter_personal_batch_status.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters3/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema coverage is 100%, so parameters are already described. The description adds 'with query or CSV file upload', hinting at two modes, but does not add specific parameter semantics beyond the schema.

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

  Purpose4/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description clearly states it creates a batch search task, distinguishing it from the personal search tool (hunter_personal_search) which likely does single searches, but it does not explicitly contrast with siblings.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines2/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  No guidance on when to use batch vs search, no prerequisites, no mention of when to use query vs file upload, and no alternatives listed.

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

• hunter_personal_batch_statusC
  2.9/5.0
  Behavior2/5

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

  No annotations are provided, so the description must inform about behavioral traits. It only says 'Get ... progress' and does not disclose read-only nature, auth requirements, rate limits, or error handling for invalid task IDs.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness4/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is a single sentence, front-loaded with the action and resource. It is concise with no wasted words, though a bit too brief for a complete understanding.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness2/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given the tool's simplicity and lack of output schema, the description should mention that it is a polling endpoint for progress tracking. It omits return values, expected polling behavior, and error conditions, leaving the agent underinformed.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters3/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema coverage is 100% with one parameter well-described in the schema as 'Task ID returned by hunter_personal_batch_create.' The description adds no extra meaning beyond the schema, meeting the baseline for high coverage but not compensating for any gaps.

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

  Purpose4/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description clearly states the verb 'Get' and the resource 'Hunter personal batch task progress,' making the tool's purpose evident. However, it does not explicitly differentiate from siblings like hunter_enterprise_batch_status, but the name and parameter hint at personal account usage.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines2/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  No guidance on when to use this tool versus alternatives (e.g., enterprise batch status or batch create). The description does not mention polling prerequisites or that the task_id must come from hunter_personal_batch_create, though this is implied by the schema.

• hunter_personal_searchC
  2.9/5.0
  Behavior2/5

  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 does not disclose behavioral traits such as authentication requirements, rate limits, pagination behavior, or whether the operation is read-only. The list of fields is helpful but not behavioral.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness4/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is concise: one sentence stating the action and a list of fields. The structure is clear and front-loaded. The field list is long but relevant.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness2/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given the number of parameters (9), the presence of many sibling tools, and no output schema, the description is minimal. It lacks information on how to construct queries, result format, or error scenarios. It covers only the basic purpose and available fields.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters3/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Parameter schema coverage is 100%, so each parameter already has a description. The tool description lists additional personal fields specific to this API, which adds context beyond the schema, but does not significantly enhance understanding of parameter usage.

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

  Purpose4/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description clearly states the tool performs a search on the Hunter personal API, and lists many personal fields. However, it does not differentiate from sibling tools like hunter_enterprise_search or fofa_search, which also have similar search functionality.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines2/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Tool is simple with no parameters and output schema exists. Description covers basic purpose but lacks depth in behavioral context (e.g., auth requirements).

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters4/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Zero parameters, so baseline is 4. Description adds value by listing what is returned (details, quota, token, role) beyond the empty schema.

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

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  Description clearly states the verb 'Get' and the resource 'Quake user details, quota, token, and role information'. It distinguishes from sibling search tools and other platform user info tools.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines2/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  No explicit guidance on when to use this tool versus alternatives. For a simple info retrieval, usage is implied but could be improved by mentioning it's for account-related queries.

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

• hunter_enterprise_batch_downloadA
  3.6/5.0
  Behavior2/5

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

  No annotations are present, so the description must carry the full burden of behavioral disclosure. It only states a download operation without discussing side effects, overwriting behavior, permissions required, or error conditions. This is insufficient for a complete behavioral profile.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness5/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  A single sentence of 9 words, front-loaded with the action and resource. Every word is necessary; no filler or repetition. Highly efficient.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness4/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  For a simple download tool with two parameters and no output schema, the description covers the essentials. It could mention file format explicitly, but the parameter description implies CSV. The context of being the final step in a batch process is clear enough from the sibling tools.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters3/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema coverage is 100% with descriptions for both parameters. The description adds marginal value by indicating the source of task_id ('returned by hunter_enterprise_batch_create') and clarifying that output_path is local. However, this does not significantly extend beyond schema information.

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

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description clearly states the action ('Download') and the resource ('Hunter enterprise batch task export file') and specifies the target ('to output_path'). It effectively distinguishes from sibling tools like hunter_enterprise_batch_create and hunter_enterprise_batch_status, which handle other lifecycle stages.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines3/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description implies usage after a batch task is created (via 'task_id'), but does not explicitly state when to use this tool over alternatives or exclude inappropriate contexts. No when-not or alternative tool guidance is provided.

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

• hunter_enterprise_user_infoA
  3.6/5.0
  Behavior2/5

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

  No annotations are present, and the description does not disclose behavioral traits beyond the basic function. There is no mention of rate limits, authentication requirements, or data volume. For a read-only tool with no parameters, minimal transparency is acceptable, but some additional context would be beneficial.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness5/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is a single sentence of 10 words, containing no waste. It is front-loaded with the action and resource.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness4/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given no parameters, no output schema, and no annotations, the description adequately communicates the tool's purpose. However, it could be slightly more detailed about what 'account information' includes, but overall it is complete for the tool's simplicity.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters4/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  The tool has no parameters, and the schema description coverage is 100% (empty schema). According to the rubric, 0 parameters yields a baseline of 4. The description does not need to add parameter information.

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

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description clearly states 'Get Hunter enterprise or sub-account quota and account information.' It uses a specific verb ('Get') and identifies the resource ('enterprise or sub-account quota and account information'), which distinguishes it from sibling tools like hunter_personal_user_info.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines2/5

  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, such as hunter_personal_user_info for personal accounts. The description does not specify context or exclusions.

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

• quake_service_scrollA
  3.6/5.0
  Behavior2/5

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

  No annotations are provided. The description mentions pagination_id usage but omits key behavioral details like the 5-minute expiration (only present in parameter description), rate limits, or any side effects. For a tool with no annotations, this is insufficient.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness5/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  Two sentences, zero fluff. Every word adds value—action, resource, and pagination workflow in a compact form.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness4/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given an output schema exists and the schema covers parameters, the description's emphasis on the pagination flow is appropriate. However, it could mention that this tool is for iterating large result sets requiring multiple requests.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters3/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema coverage is 100%, so parameters are already well-described. The tool description adds no additional meaning beyond what the schema provides, meeting the baseline expectation.

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

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description clearly states the action is 'deep-pagination Quake service search' and specifies the REST endpoint. This distinguishes it from sibling tools like quake_service_search, which likely handles single-page results.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines3/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description explains how to paginate (using pagination_id from response) but does not explicitly state when to use this tool over alternatives like quake_service_search. It assumes the agent understands 'deep-pagination' context.

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

• fofa_search_statsA
  3.7/5.0
  Behavior2/5

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

  With no annotations provided, the description bears full responsibility for behavioral disclosure. It only mentions a rate limit (throttling) but does not state if the tool is read-only, idempotent, or requires specific authentication. Significant gaps remain.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness5/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is two concise sentences: first states the purpose, second provides critical usage info (throttling) and supported fields. Front-loaded with essential information, no redundancy.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness3/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given that an output schema exists (context indicates true), the description need not detail return values. However, it could better explain that the tool provides aggregated statistics or counts per field. The listed fields are helpful, but the aggregation nature is only hinted at.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters4/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema description coverage is 100%, so baseline is 3. The description adds value by listing the full set of supported aggregation fields (protocol, domain, port, etc.), which goes beyond the schema's default value and clarifies what fields are valid.

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

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description clearly states the tool aggregates FOFA search results using the /api/v1/search/stats endpoint, with a specific verb and resource. It also lists supported fields, distinguishing it from sibling search tools that return raw results or paginate.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines3/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description mentions throttling but does not explicitly state when to use this tool versus alternatives like fofa_search or other aggregation tools. Usage context is implied through the term 'aggregate' but no direct guidance is given.

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

• quake_aggregation_fieldsA
  3.7/5.0
  Behavior2/5

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

  No annotations are provided, and the description does not disclose any behavioral traits such as read-only nature, authentication requirements, or rate limits. The simple action of 'getting fields' implies idempotency but is not explicitly stated.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness4/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is a single sentence followed by a long list of examples. While the list is extensive, it is informative and does not contain extraneous information. It could be slightly more concise by omitting some examples, but overall acceptable.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness4/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given the absence of parameters and presence of an output schema, the description is largely complete. It explains the purpose and provides example values, though it does not describe the output format or structure, which is provided by the schema.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters4/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  With zero parameters, the schema covers everything trivially. The description adds value by listing example fields, but this pertains to output rather than parameters. Baseline score of 4 applies.

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

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description clearly states the tool gets Quake service aggregation fields via a specific endpoint and provides numerous examples, distinguishing it from siblings like quake_filterable_fields or quake_service_aggregation.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines3/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  No explicit guidance on when to use this tool vs alternatives. It is implied that it provides available fields for aggregation, but no direct comparison or usage context is given.

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

• zoomeye_searchA
  3.7/5.0
  Behavior2/5

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

  With no annotations provided, the description bears full responsibility for behavioral disclosure. It mentions automatic Base64 encoding and paid-account requirements but fails to disclose authentication needs, rate limits, pagination behavior, or cost implications. For a search tool, lack of these details reduces transparency.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness5/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description consists of two concise sentences with no redundant information. It is front-loaded with the main action and efficiently covers key points: endpoint, query options, and unsupported APIs.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness3/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given the 8 parameters (all optional), 100% schema coverage, and presence of an output schema, the description is adequate but not thorough. It explains the query mechanism and scope but omits return format, pagination details, and error handling. For a search tool in a competitive suite, more completeness would be beneficial.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters3/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema coverage is 100%, so baseline is 3. The description adds context about the query and qbase64 parameters, explaining the relationship (raw query gets auto-encoded vs. direct base64). This adds marginal value beyond the schema descriptions, which already include examples and defaults.

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

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description clearly states the tool searches ZoomEye paid-account assets using POST /v2/search, specifying the verb, resource, and API method. It distinguishes from siblings by explicitly noting that free and legacy APIs are not supported, which separates it from related tools like fofa_search or quake_search.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines4/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description provides clear usage guidance: users can either provide a raw query (automatic Base64 encoding) or pass qbase64 directly. It also mentions that free/legacy APIs are not supported, implying when not to use the tool. However, it does not explicitly suggest alternative tools for free or legacy accounts, which would improve clarity.

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

• hunter_enterprise_batch_statusA
  3.9/5.0
  Behavior2/5

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

  No annotations are provided, so the description must fully disclose behavioral traits. It only states 'Get ... progress' without explaining that the tool is read-only, whether it can be called multiple times, what happens if the task ID is invalid, or what the response format looks like. This is a significant gap for a tool that checks asynchronous progress.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness5/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is a single, front-loaded sentence that captures the essence of the tool with zero wasted words. It is maximally concise while remaining informative.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness3/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given the low complexity (one parameter, no output schema), the description provides minimal but adequate information. However, it does not specify what 'progress' entails (e.g., status enums, completion percentage) or whether the tool returns immediately or waits. This leaves some ambiguity for an agent.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters4/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  The schema covers 100% of parameters, but the description adds value by specifying that task_id is 'returned by hunter_enterprise_batch_create.' This tells the agent exactly how to obtain a valid task ID, which is more helpful than just the schema type alone.

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

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description uses a specific verb 'Get' and identifies the resource as 'Hunter enterprise batch task progress.' It clearly distinguishes from sibling tools like hunter_enterprise_batch_create, hunter_enterprise_batch_download, and hunter_enterprise_batch_pull, each of which handles different stages of the batch workflow.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines4/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  Although the description lacks explicit 'when to use' or 'when not to use' statements, the parameter description for task_id states 'Task ID returned by hunter_enterprise_batch_create,' which implies the tool should be used after creating a batch task to check its progress. This provides indirect usage guidance.

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

• hunter_personal_user_infoA
  3.9/5.0
  Behavior3/5

  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 indicates a read-only operation ('Get'), but does not disclose any potential side effects, rate limits, or authentication requirements. For a simple info retrieval, this is adequate but not thorough.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness5/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is a single sentence with no extra words. It is appropriately sized for the tool's simplicity.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness3/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  The tool has no parameters and no output schema. The description mentions 'account quota and account information' but lacks specifics on the structure of the response. For a simple tool, it is somewhat complete but could be more detailed about what exactly is returned.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters4/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  There are no parameters, so per the rubric baseline of 4. The schema coverage is 100% trivially, and the description does not need to add parameter details.

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

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description uses the verb 'Get' with a specific resource: 'Hunter personal account quota and account information'. It clearly distinguishes from sibling tools like 'hunter_enterprise_user_info' by specifying 'personal'.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines3/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  No explicit when-to-use or alternatives are given, but the purpose is straightforward and implied. It might be used when the agent needs account quota or info, but there is no guidance on when not to use it.

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

• quake_service_searchA
  3.9/5.0
  Behavior3/5

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

  No annotations provided, so description carries full burden. It mentions 'real-time' but lacks details on rate limits, authentication, response format, or side effects. Adequate but not comprehensive.

  Conciseness5/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  Two concise sentences front-loading purpose and usage guidance. Every sentence earns its place with zero redundancy.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness3/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given 12 parameters and an output schema, the description does not elaborate on return values or common patterns. It provides essential usage context but lacks depth for a complex tool.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters3/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema coverage is 100%, so baseline 3 applies. Description adds no extra meaning beyond schema descriptions; it merely restates the endpoint.

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

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  Clearly states the verb 'Run real-time Quake service search' with specific resource and endpoint. Distinguishes from sibling quake_service_scroll by indicating usage for small result sets.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines4/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  Explicitly recommends use for small result sets and directs to quake_service_scroll for deep pagination. Provides clear context but does not explicitly list when not to use.

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

• zoomeye_user_infoA
  4/5.0
  Behavior3/5

  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 indicates a read operation ('Get'), which is non-destructive, but does not disclose authentication requirements, idempotency, or rate limits. For a simple info tool, this is minimally adequate but lacks depth.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness5/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is a single concise sentence with no superfluous words. It immediately states the action and resource, ensuring clarity without waste.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness4/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  The description covers the essential action and resource, and an output schema is provided. It does not mention related tools or prerequisites (e.g., needing a paid account), but for a simple info endpoint with no parameters, it is reasonably complete.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters4/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  There are no parameters, so the description does not need to add parameter meaning. The baseline for zero parameters is 4, and the description correctly focuses on the tool's action without missing parameter information.

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

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description clearly states the verb 'Get', the resource 'paid-account subscription and points information', and the HTTP method and path 'POST /v2/userinfo'. It unambiguously identifies the tool's purpose and distinguishes it from siblings like zoomeye_search and other service info tools.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines3/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description does not explicitly state when to use this tool vs alternatives or provide context on usage. However, the tool's name and description imply it is for retrieving account information, so usage context is inferred but not explicitly guided.

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

• fofa_user_infoA
  4.1/5.0
  Behavior3/5

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

  No annotations provided. Description implies read-only operation ('get info'), but does not explicitly state safety, authentication needs, or rate limits. Adequate for a simple query with no side effects.
