Tool Scores

• add_auth_to_specC
  2.4/5.0
  Behavior1/5

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

  The description claims the tool is 'read-only and stateless' yet its name and purpose imply modification. This internal contradiction severely undermines transparency. No annotations exist to clarify.

  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?

  The description is verbose and repetitive, with a 'Behavior' section that largely duplicates the 'Behavioral Transparency' section. Structure is poor and could be more concise.

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

  Completeness1/5

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

  The description fails to explain the output format, how the auth is incorporated into the spec, or criteria for success/failure. Essential context is missing, and the contradictory read-only claim adds confusion.

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

  Parameters2/5

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

  With 0% schema description coverage, the description only provides generic phrases like 'to analyze or process' for each parameter, adding no meaningful detail beyond what the schema already shows.

  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 adds an authentication scheme to an OpenAPI spec, listing specific auth types (bearer, api_key, basic, oauth2). This distinguishes it from sibling tools like generate_endpoint or validate_spec.

  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 'When to use' section is mismatched, referring to 'structured analysis or classification' rather than adding auth. No explicit alternatives are given, and the guidance is vague.

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

• generate_schemaA
  3.7/5.0
  Behavior5/5

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

  With no annotations, the description fully covers side effects (read-only, no modifications), authentication (none for basic, API key for Pro), rate limits (10/day free), error handling, idempotency, and data privacy. This is exemplary and leaves no ambiguity.

  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?

  Well-structured with headings, but verbose with repetition (e.g., behavior section overlaps with behavioral transparency). Could be more concise while retaining key info.

  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?

  Covers behavior, usage, parameters, and error handling extensively, but lacks output format description and does not clarify how this tool complements siblings like validate_spec. Without output schema, the return structure is vague.

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

  Parameters2/5

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

  Schema coverage is 0%, so the description must compensate, but parameter explanations are generic ('The name to analyze or process'). The 'fields' parameter gets slight elaboration (format specification), but overall adds minimal value 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 'Generate an OpenAPI schema component,' specifying the verb and resource. It distinguishes from sibling tools like generate_endpoint and generate_full_spec by focusing on schema components, though the later generic 'structured analysis' line slightly blurs focus.

  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?

  Explicit 'When to use' and 'When NOT to use' sections provide context, advising against real-time production use without human review. However, it does not explicitly differentiate from sibling tools like add_auth_to_spec or validate_spec.

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

• generate_full_specA
  4/5.0
  Behavior5/5

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

  With no annotations provided, the description fully covers behavioral traits including side effects (read-only), authentication, rate limits, error handling, idempotency, and data privacy. This is comprehensive and exceeds typical expectations.

  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 well-structured into sections but is verbose. It repeats information (e.g., behavioral details in two places) and includes redundant lists that mirror the schema. Could be more concise without losing clarity.

  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 description covers overall purpose, input format, and behavioral traits. However, it lacks details on the output format (JSON? YAML?) and how required parameters (title, description) contribute to the spec. The tool's documentation is adequate but has clear gaps.

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

  Parameters2/5

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

  Schema description coverage is 0%, so the description must compensate. However, parameter descriptions are generic and tautological (e.g., 'The title to analyze or process'). Only endpoints_json receives meaningful context in the opening paragraph. Most parameters lack specific guidance on expected values or formats.

  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 it generates a complete OpenAPI 3.0 spec and specifies the input format (endpoints_json as JSON array). It is distinct from siblings like generate_endpoint, generate_schema, add_auth_to_spec, and validate_spec.

  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 includes explicit 'When to use' and 'When NOT to use' sections, guiding the agent on appropriate contexts. However, it does not directly compare to sibling tools or provide specific exclusions for when to use alternatives.

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

• generate_endpointA
  4.1/5.0
  Behavior5/5

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

  Despite no annotations, the description comprehensively covers all behavioral aspects: side effects (read-only), authentication (none for basic, pro key), rate limits (10/day free, unlimited pro), error handling (structured errors), idempotency, and data privacy. This fully compensates for missing annotations.

  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 well-organized with clear sections (Behavior, When to use, etc.) and front-loads the main purpose. While lengthy, every section adds relevant detail. Some parameter descriptions are repetitive, but overall structure is 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?

  Given the complexity and lack of output schema, the description provides good coverage of inputs, behaviors, and return format (structured errors). It could benefit from briefly describing the output shape (e.g., structure of the generated endpoint definition), but it's largely complete for an agent to invoke correctly.

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

  Parameters2/5

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

  Schema description coverage is 0%. The description lists parameters but uses generic phrases like 'The path to analyze or process' that add minimal context beyond the parameter name. For example, 'path' and 'method' are not explained in terms of format, allowed values, or how they affect the generated endpoint definition.

  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 generates an OpenAPI endpoint definition. While it doesn't explicitly differentiate from sibling tools like 'generate_schema' or 'generate_full_spec', the specific verb 'endpoint definition' combined with the tool name makes the purpose reasonably clear.

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

  Usage Guidelines5/5

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

  Explicit 'When to use' and 'When NOT to use' sections provide clear guidance. States it's for structured analysis/classification and explicitly warns against using for real-time production without human review, helping the agent choose appropriately.

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

• validate_specA
  4.1/5.0
  Behavior5/5

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

  Thoroughly documents side effects (none), authentication (no auth for basic, pro key required), rate limits (10/day free), error handling (structured errors), idempotency, and data privacy. Since no annotations exist, the description fully compensates.

  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?

  Well-structured with sections, but verbose. The Behavioral Transparency block repeats info from the Behavior section. Could be more concise while retaining key details.

  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?

  Covers many aspects (behavior, auth, rate limits, error handling) despite no annotations or output schema. Missing: examples of common issues detected and the structure of the analysis output.

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

  Parameters2/5

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

  With 0% schema description coverage, the description provides only minimal parameter info (name, type, vague purpose). It does not explain format, constraints, or behavior differences between parameters, e.g., api_key usage for pro tier is only hinted in transparency, not in args.

  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 'Validate an OpenAPI spec for common issues' with a specific verb and resource. It distinguishes from sibling tools like add_auth_to_spec, generate_endpoint, etc., which perform different operations.

  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?

  Includes explicit 'When to use' and 'When NOT to use' sections, giving context and an exclusion (not for real-time decisions without review). However, it does not name alternative sibling tools explicitly.

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