Tool Scores

• validate_json_schemaB
  3.4/5.0
  Behavior2/5

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

  Mentions 'detailed error reporting' but does not specify success/failure behavior, output format, or whether exceptions are thrown, which is critical since no annotations exist.

  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, front-loaded with the main action, no redundant information.

  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?

  No output schema and no description of return format or error handling, leaving the agent without necessary behavioral context.

  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?

  Input schema covers both parameters with clear descriptions, so the tool description adds no additional meaning; baseline 3 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?

  Clearly states 'Validate JSON data against a schema' with specific verb and resource, and distinguishes from sibling tools like transform_csv_to_json and normalize_data.

  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?

  Describes a use case ('receiving API responses or user data that needs validation') but lacks explicit when-not-to-use or alternative tools.

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

• merge_datasetsA
  3.5/5.0
  Behavior2/5

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

  No annotations provided, so description carries full burden. Describes deduplication and conflict resolution but lacks details on edge cases, performance, or return behavior.

  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 with no wasted words, perfectly sized for the information conveyed.

  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 3 parameters, no output schema, and no annotations, description covers core purpose but omits return format, behavior on missing keys, and specifics of conflict resolution modes.

  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%, baseline 3. Description reiterates concepts in schema (e.g., 'deduplication' maps to merge_key, 'conflict resolution' to conflict_resolution) but adds no new detail beyond what schema provides.

  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 verb 'merge', resource 'JSON datasets', and key capabilities 'deduplication and conflict resolution'. Distinguishes from siblings like validate_json_schema and transform_csv_to_json.

  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?

  Implied usage with 'perfect for agents combining data from multiple sources', but no explicit when-not-to-use or alternatives mentioned.

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

• transform_csv_to_jsonA
  3.5/5.0
  Behavior3/5

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

  No annotations provided, so description is the sole source. It discloses key behaviors: delimiter auto-detection, type inference, and handling of messy data. However, it lacks details on error handling, performance, limits, or output format specifics.

  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 with no filler, front-loading the main action 'Convert CSV data to structured JSON'. Every word adds value, 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.

  Completeness3/5

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

  Given no output schema, description should explain return format but only implies JSON output. No mention of error handling, size limits, or behavior with empty/malformed input. Covers main features but leaves gaps for a complete understanding.

  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 50% (options object lacks top-level description). The description adds context about auto-detecting delimiters and inferring types, which relates to the 'delimiter' and 'infer_types' fields. However, it does not explicitly tie these behaviors to the parameters or elaborate on the 'csv_data' parameter.

  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 tool converts CSV data to structured JSON with intelligent type inference. It specifically mentions handling messy CSV, auto-detecting delimiters, and inferring types, which distinguishes it from sibling tools like normalize_data or clean_text.

  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. The description implies it's for CSV-to-JSON conversion with automatic handling, but does not mention when not to use it or provide comparisons to sibling tools.

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

• normalize_dataA
  3.7/5.0
  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 says it 'standardizes' formats, but does not mention what happens on invalid data, whether it modifies data in place or returns a copy, or any error handling. For a data transformation tool, this lack of transparency could lead to misuse.

  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 that first state the core purpose with examples, then add usage context. No filler words. Every sentence earns its place. Excellent front-loading.

  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 purpose and usage context, but lacks information about return value (does it return the normalized array?) and error behavior (e.g., how are invalid inputs handled?). Given the moderate complexity (nested objects, no output schema), this additional information would be helpful for an agent to correctly invoke and process the output.

  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 33% (only data and fields have descriptions, target_formats lacks top-level description but subproperties have them). The description mentions formats like dates and phones, which maps to fields, but adds no new meaning beyond the schema. It also doesn't clarify the structure or behavior of target_formats. Baseline at high coverage is 3.

  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 starts with 'Standardize common data formats' which clearly names the action and resource, and lists examples (dates, phone numbers, currencies, addresses). It distinguishes from siblings like validate_json_schema, transform_csv_to_json, clean_text, and merge_datasets, which have different purposes.

  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 says 'Essential for agents processing user input or scraped data with inconsistent formatting.' This provides clear context for when to use the tool. However, it does not state when not to use it or suggest alternatives, so it misses a small opportunity for fuller guidance.

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

• clean_textA
  4.2/5.0
  Behavior3/5

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

  No annotations provided, so description carries full burden. Lists operations but omits details like idempotency, handling of invalid inputs, or exact whitespace normalization behavior. 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?

  Two sentences: first lists actions, second states ideal use case. No redundant words; front-loaded with key info.

  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?

  Simple tool with clear purpose; description suffices for an agent to understand when and what it does. Missing return value description, but output is intuitive (cleaned text).

  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 coverage is 50% (only 'text' has a description at top level; 'options' lacks description). Description compensates by naming the operations, directly mapping to the options' functions, adding meaning beyond 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 specific actions: remove HTML tags, fix encoding, normalize whitespace, extract clean text. Sibling tools like validate_json_schema or normalize_data have no overlap, making this tool distinct.

  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 scraped web content or user-submitted text. Lacks mention of when not to use or alternatives, but context is clear enough for an agent.

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