Tool Scores

• get_my_qiita_articlesC
  2.9/5.0
  Behavior2/5

  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. It states it's for getting articles, implying a read operation, but doesn't specify authentication requirements, rate limits, pagination behavior beyond the schema, or what the return format looks like. For a tool with zero annotation coverage, 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.

  Conciseness4/5

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

  The description is a single, efficient sentence that directly states the tool's purpose without unnecessary words. It's appropriately sized for a simple tool, though it could be slightly more informative without losing conciseness. No structural issues are present.

  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 complexity (a read operation with pagination), lack of annotations, and no output schema, the description is incomplete. It doesn't explain authentication needs, return format, or error handling, leaving gaps for the agent. For a tool with 2 parameters and no structured behavioral hints, more context is needed to be fully helpful.

  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?

  The schema description coverage is 100%, with both parameters ('page' and 'per_page') well-documented in the schema itself. The description adds no additional meaning beyond what the schema provides, such as default values or usage context. Baseline 3 is appropriate when the schema does the heavy lifting, but no extra value is added.

  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 resource ('current authenticated user qiita articles'), making the purpose understandable. It distinguishes from siblings like 'get_qiita_item' by specifying it's for the authenticated user's articles, not general items. However, it doesn't explicitly contrast with 'post_qiita_article' or 'update_qiita_article', which are write operations, so it's not a perfect 5.

  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?

  The description provides no guidance on when to use this tool versus alternatives. It doesn't mention that 'get_qiita_item' might be for specific items by ID, or that 'post_qiita_article' and 'update_qiita_article' are for creating/modifying articles. There's no context on prerequisites like authentication, leaving the agent to infer usage from the name alone.

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

• get_qiita_itemC
  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 of behavioral disclosure. It states the tool fetches an article but doesn't describe key behaviors: whether it requires authentication, returns public/private articles, handles errors (e.g., invalid IDs), or provides rate limits. This leaves significant gaps for a read operation.

  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, efficient sentence with no wasted words. It's front-loaded with the core purpose ('get a specific Qiita article'), making it easy to parse quickly.

  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 lack of annotations and output schema, the description is incomplete. It doesn't explain what the tool returns (e.g., article content, metadata), error handling, or authentication needs. For a tool with no structured behavioral data, this leaves the agent under-informed about how to use it effectively.

  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?

  The schema description coverage is 100%, with the parameter 'item_id' clearly documented in the schema. The description adds no additional parameter semantics beyond implying the ID is used to fetch an article, which aligns with the schema. This meets the baseline for high schema coverage.

  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 action ('get') and resource ('a specific Qiita article by its ID'), making the purpose understandable. However, it doesn't explicitly differentiate from sibling tools like 'get_my_qiita_articles' (which likely fetches multiple articles for the current user) or 'get_qiita_markdown_rules' (which fetches formatting rules rather than articles).

  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?

  The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an article ID), contrast with sibling tools (e.g., 'get_my_qiita_articles' for user-specific articles), or specify scenarios where this tool is appropriate (e.g., fetching a single public article).

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

• post_qiita_articleC
  2.9/5.0
  Behavior2/5

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

  With no annotations provided, the description carries full burden but only states the basic action without disclosing behavioral traits. It doesn't mention authentication requirements, rate limits, whether the creation is irreversible, or what happens on success/failure. For a write operation with zero annotation coverage, this is a significant gap.

  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, efficient sentence with zero wasted words. It's front-loaded with the core action and resource, making it easy to parse quickly, though its brevity contributes to gaps in other dimensions.

  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 creation tool with no annotations and no output schema, the description is incomplete. It lacks context about authentication, error handling, return values, or how it differs from sibling tools. The high schema coverage doesn't compensate for missing behavioral and usage information.

  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 description coverage is 100%, so the schema fully documents all 7 parameters. The description adds no parameter-specific information beyond implying creation, which doesn't enhance understanding of individual parameters. Baseline 3 is appropriate when the schema does all the work.

  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 action ('create') and resource ('a new article on Qiita'), making the purpose immediately understandable. However, it doesn't differentiate from sibling tools like 'update_qiita_article' beyond the basic verb difference, missing explicit comparison.

  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?

  The description provides no guidance on when to use this tool versus alternatives like 'update_qiita_article' or 'get_my_qiita_articles'. It lacks context about prerequisites (e.g., authentication needed) or typical use cases, leaving the agent to infer usage solely from the tool name.

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

• update_qiita_articleC
  2.9/5.0
  Behavior2/5

  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. It states 'update' which implies mutation, but doesn't disclose critical behavioral traits like required permissions, whether changes are reversible, rate limits, or what happens to unspecified fields (partial vs full updates). This leaves significant gaps for a mutation tool.

  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, efficient sentence with zero wasted words. It's appropriately sized and front-loaded with the core purpose, making it easy to parse quickly.

  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 mutation tool with 7 parameters, no annotations, and no output schema, the description is insufficiently complete. It doesn't address behavioral aspects like permissions, side effects, or response format, leaving the agent with inadequate context to use the tool safely and effectively.

  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?

  The schema description coverage is 100%, so the schema already documents all 7 parameters thoroughly. The description adds no parameter information beyond what's in the schema, maintaining the baseline score of 3 for adequate but no extra value.

  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 action ('update') and resource ('an existing Qiita article'), providing a specific verb+resource combination. However, it doesn't differentiate from sibling tools like 'post_qiita_article' (create vs update), which prevents a perfect score.

  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?

  The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an existing article ID), when not to use it, or how it differs from 'post_qiita_article' for creation versus update operations.

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

• get_qiita_markdown_rulesB
  3.1/5.0
  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 of behavioral disclosure. It states the tool retrieves markdown rules, implying a read-only operation, but doesn't specify aspects like whether it requires authentication, rate limits, or the format of the returned data. This leaves significant gaps in understanding how the tool behaves in practice.

  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 extremely concise and front-loaded: 'get Qiita markdown syntax rules, cheat sheet'. It uses minimal words to convey the core purpose without redundancy or unnecessary elaboration, making it efficient and easy to parse.

  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 lack of annotations and output schema, the description is incomplete for a tool that likely returns structured data (e.g., markdown rules). It doesn't hint at the response format, potential errors, or any behavioral traits, leaving users with insufficient context to use the tool effectively beyond its basic purpose.

  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 0 parameters, and the input schema has 100% description coverage (though empty). The description doesn't need to add parameter semantics, as there are none to explain. A baseline score of 4 is appropriate since the schema fully covers the lack of parameters, and the description doesn't introduce confusion.

  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's purpose: 'get Qiita markdown syntax rules, cheat sheet'. It uses a specific verb ('get') and identifies the resource ('Qiita markdown syntax rules'), making the action and target clear. However, it doesn't explicitly differentiate from sibling tools like 'get_qiita_item', which might also retrieve content-related information.

  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?

  The description provides no guidance on when to use this tool versus alternatives. It doesn't mention sibling tools or contexts where this tool is appropriate, such as when needing formatting rules versus actual articles. Without such guidance, users must infer usage from the tool name alone.

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