• persona_pm_toolC
  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 for behavioral disclosure. It mentions the tool generates plans from files and can use decision-making functionality, but lacks critical behavioral details: whether it modifies input files, what permissions are needed, how it handles errors, rate limits, or what happens with conflicting parameters. For a 10-parameter tool with file operations, this is insufficient 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 well-structured with clear sections: purpose statement, functional explanation, parameter list, and return value. It's appropriately sized for a 10-parameter tool. Some sentences could be more concise (e.g., the two-sentence opening could be combined), but overall it's efficiently organized with front-loaded 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?

  Given the tool's complexity (10 parameters, file operations, no annotations, no output schema), the description is incomplete. It explains what the tool does and lists parameters, but lacks crucial context: error handling, file format requirements, output structure beyond file path, performance characteristics, and how the decision-making functionality actually works. For such a sophisticated tool, more comprehensive documentation is needed.

  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. It provides an 'Args' section listing all 10 parameters with brief explanations, adding meaningful semantics beyond the bare schema. However, the explanations are terse and don't cover parameter interactions, constraints, or detailed usage examples. For a complex tool with many parameters, this is only partially adequate.

  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: 'Generate product management plans using a specialized Product Manager persona, with optional decision making.' It specifies the verb ('generate'), resource ('product management plans'), and persona context. However, it doesn't explicitly differentiate from sibling tools like persona_ba_tool or persona_dm_tool, which likely use different personas for 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 Guidelines3/5

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

  The description implies usage context by mentioning 'optional decision making' and describing two modes (single model vs. team decision-making), but it doesn't provide explicit guidance on when to choose this tool over alternatives like persona_ba_tool or prompt_from_file_tool. The tool's specialized persona suggests it's for product management tasks, but no explicit when/when-not rules are stated.

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

• persona_ba_toolB
  3/5.0
  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 mentions that the tool 'analyzes business requirements from a file' and can use 'multiple perspectives and consolidate them,' but lacks critical details: it doesn't specify if this is a read-only or write operation (though implied by 'Generate'), what permissions are needed, any rate limits, error handling, or the format of the output file beyond its path. For a complex 10-parameter tool with no annotation coverage, 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.

  Conciseness3/5

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

  The description is appropriately front-loaded with a clear purpose statement, but it's lengthy due to the detailed parameter explanations. While the 'Args' and 'Returns' sections are structured, the overall text could be more concise; some parameter details might be redundant if the schema were better documented. Every sentence adds value, but it's not optimally streamlined.

  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 tool's complexity (10 parameters, no annotations, no output schema), the description is moderately complete. It covers the purpose and parameters well, but lacks behavioral context (e.g., side effects, error cases) and output details beyond the file path. Without annotations or an output schema, more information on the generated analysis format or usage constraints would improve completeness.

  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 description includes a detailed 'Args' section that explains all 10 parameters, adding significant meaning beyond the input schema, which has 0% description coverage. It clarifies the purpose of each parameter (e.g., 'from_file: Path to the file containing the business requirements'), default values, and interactions (e.g., how 'use_decision_maker' relates to 'decision_maker_models'). This compensates well for the schema's lack of descriptions.

  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: 'Generate business analysis using a specialized Business Analyst persona, with optional decision making.' It specifies the verb ('Generate'), resource ('business analysis'), and persona context. However, it doesn't explicitly differentiate from sibling tools like 'persona_pm_tool' or 'persona_dm_tool', which likely serve different persona-based functions.

  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 minimal guidance on when to use this tool. It mentions 'optional decision making' and that it can 'use a single model or leverage the team decision-making functionality,' but offers no explicit when/when-not criteria or alternatives. There's no mention of prerequisites, such as needing a requirements file, or comparison to sibling tools like 'prompt_from_file_tool' for similar tasks.

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

• persona_sw_toolB
  3.1/5.0
  Behavior3/5

  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 describes the tool's core functionality (generating specs with optional decision-making) and mentions default behaviors (e.g., default models and output directory). However, it lacks details on error handling, rate limits, permissions, or what happens if inputs are invalid. It doesn't contradict annotations, but it's insufficient for a mutation tool with 10 parameters.

  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-structured with a clear purpose statement followed by 'Args' and 'Returns' sections. It's appropriately sized for a complex tool, though some parameter explanations could be more concise. The front-loaded purpose sentence earns its place, but the detailed default prompt templates might be excessive if they're standard configurations.

  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 (10 parameters, no annotations, no output schema), the description is incomplete. It covers the basic workflow and parameters but lacks crucial context: no error handling, no performance expectations, no details on the output format beyond the file path, and no guidance on model selection or decision-making trade-offs. For a generative tool with many options, this leaves significant gaps for an AI agent.

  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. It lists all 10 parameters in the 'Args' section with brief explanations, adding meaning beyond the schema's titles. However, the explanations are minimal (e.g., 'Path to the file containing the requirements or PRD' for 'from_file') and don't cover formats, constraints, or interactions between parameters like 'output_dir' and 'output_path'. This partial compensation is inadequate given the high parameter count.

  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: 'Generate specification documents using a specialized Spec Writer persona, with optional decision making.' It specifies the verb ('generate'), resource ('specification documents'), and method ('using a specialized Spec Writer persona'). However, it doesn't explicitly differentiate from sibling tools like 'persona_ba_tool' or 'persona_pm_tool', which likely serve different persona-based functions.

  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 context by mentioning 'optional decision making' and the ability to use 'a single model or leverage the team decision-making functionality.' However, it doesn't provide explicit guidance on when to use this tool versus alternatives like 'prompt_from_file_tool' or 'persona_dm_tool', nor does it specify prerequisites or exclusions beyond the required 'from_file' parameter.

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

• list_models_toolB
  3.2/5.0
  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 mentions the return type ('List of model names') but lacks details on permissions, rate limits, error handling, or whether the operation is read-only or has side effects, which is insufficient for a tool with zero annotation coverage.

  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 front-loaded with a clear purpose statement, followed by structured 'Args' and 'Returns' sections. Every sentence adds value without redundancy, making it efficiently sized and well-organized.

  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 tool's low complexity (one parameter) and lack of annotations or output schema, the description is minimally adequate. It covers the basic purpose and parameter semantics but misses behavioral context and usage guidelines, leaving gaps in completeness.

  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 description adds significant meaning beyond the input schema, which has 0% coverage. It explains the 'provider' parameter with examples ('e.g., "openai", "anthropic"'), clarifying its purpose and expected values, effectively compensating for the schema's lack of documentation.

  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 ('List all available models') and the resource ('for a specific provider'), making the purpose immediately understandable. However, it doesn't differentiate from sibling tools like 'list_providers_tool' which suggests a related but distinct function, so it doesn't reach the highest 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, such as how it relates to 'list_providers_tool' or other persona tools. It only describes what the tool does, not the context or prerequisites for its use.

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

• persona_dm_toolB
  3.3/5.0
  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 describes the two-step process (generate responses, then decide) and mentions file I/O (saving responses to files), but lacks critical details: whether this is a read-only or mutating operation, potential side effects (e.g., file system writes), error handling, performance characteristics, or authentication requirements. For a tool with 7 parameters and file operations, 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.

  Conciseness4/5

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

  The description is well-structured with a clear purpose statement followed by detailed parameter explanations. It's appropriately sized for a complex tool with 7 parameters. The 'Args' and 'Returns' sections are efficiently organized. Minor improvements could include bolding key terms, but overall it's front-loaded and wastes no sentences.

  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 tool's complexity (7 parameters, multi-step LLM workflow, file I/O) and lack of annotations/output schema, the description is partially complete. It excels at parameter semantics but lacks behavioral context (safety, side effects, performance). The return value is documented ('Path to the persona output file'), but without an output schema, details about the file format or content are missing. For a tool of this complexity, more behavioral disclosure would be needed for full completeness.

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

  Parameters5/5

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

  The description provides detailed semantic explanations for all 7 parameters in the 'Args' section, including purpose, format examples, and default values. Since schema description coverage is 0% (titles only, no descriptions), the description fully compensates by adding essential meaning beyond the bare schema. Each parameter's role in the workflow is clearly explained.

  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: 'Generate responses from multiple LLM models and use a decision maker model to choose the best direction.' It specifies the verb ('generate responses', 'use a decision maker model') and resource ('multiple LLM models'), but doesn't explicitly differentiate from sibling tools like persona_ba_tool or persona_pm_tool, which likely have different roles in the persona workflow.

  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 (e.g., persona_ba_tool, persona_pm_tool) or explain the context where this decision-making approach is preferred over simpler prompt tools like prompt_tool. The usage is implied through the description but not explicitly stated.

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

• prompt_from_file_toolB
  3.3/5.0
  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 discloses the basic behavior (reading from file, sending to models, returning responses) but lacks critical details: it doesn't specify authentication needs, rate limits, error handling, or whether the operation is read-only or has side effects. For a tool that interacts with external LLM models, this is a significant gap in behavioral 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 appropriately sized and front-loaded: the first sentence states the core purpose, followed by structured sections for Args and Returns. Every sentence adds value, with no redundant information. It could be slightly more concise by integrating the default value into the main description, but overall it's efficient.

  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 complexity (interacting with multiple LLM models), no annotations, no output schema, and 0% schema coverage, the description is moderately complete. It covers the basic operation and parameters but lacks details on authentication, error handling, response format, or model-specific behaviors. This is adequate for a simple tool but has clear gaps for reliable agent use.

  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 0%, so the description must compensate. It effectively adds meaning for both parameters: 'file_path' is explained as 'Path to the file containing the prompt text', and 'models_prefixed_by_provider' is detailed with format examples and a default value. This covers the semantics well, though it doesn't specify file format constraints or model availability.

  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: 'Read a prompt from a file and send it to multiple LLM models.' This specifies the verb (read and send), resource (prompt from file), and target (multiple LLM models). It distinguishes from siblings like 'prompt_tool' (likely sends a direct prompt) and 'prompt_from_file2file_tool' (likely outputs to file). However, it doesn't explicitly differentiate from all siblings, such as persona 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 implies usage when you have a prompt in a file and want to test it across models, but it doesn't explicitly state when to use this tool versus alternatives like 'prompt_tool' (for direct prompts) or 'prompt_from_file2file_tool' (for file output). It mentions a default model, which provides some context, but lacks explicit guidance on prerequisites or exclusions.

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

• list_providers_toolB
  3.4/5.0
  Behavior3/5

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

  With no annotations provided, the description carries the full burden. It discloses the return format ('Dictionary with main providers and their shortcuts clearly formatted'), which adds useful context beyond the basic purpose. However, it lacks details on potential limitations, error handling, or behavioral traits like rate limits or authentication needs.

  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 well-structured: two sentences that directly state the purpose and return value, with no wasted words. It's front-loaded with the main function, making it easy to understand quickly.

  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 tool's low complexity (0 parameters, no annotations, no output schema), the description is adequate but has gaps. It explains the return format, which is helpful, but doesn't cover usage guidelines or behavioral context fully. For a simple read-only tool, it's minimally viable but could be more comprehensive.

  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 schema description coverage is 100%, so no parameter documentation is needed. The description appropriately doesn't discuss parameters, focusing instead on the output. This meets the baseline for tools with no 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?

  The description clearly states the tool's purpose: 'List all supported LLM providers.' It specifies the verb ('List') and resource ('supported LLM providers'), making the function unambiguous. However, it doesn't explicitly differentiate from sibling tools like 'list_models_tool', which might list models rather than providers.

  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 like 'list_models_tool' or explain the context for selecting this tool over others. Usage is implied by the purpose but not explicitly stated.

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

• prompt_from_file2file_toolA
  3.6/5.0
  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 covers basic operations. It doesn't disclose critical behavioral traits such as error handling, rate limits, authentication needs, file format requirements, or whether it overwrites existing files. The description adds minimal context beyond the core functionality.

  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-structured with a clear purpose statement followed by parameter details. It's appropriately sized for a 5-parameter tool, though the parameter explanations could be more front-loaded. Every sentence adds value, with minimal 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 the tool's complexity (multi-model processing, file I/O) and lack of annotations/output schema, the description is moderately complete. It covers core functionality and parameters but omits important context like error behavior, response formats, or performance characteristics. The return value is documented, but overall completeness is adequate with noticeable gaps.

  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 0%, so the description must compensate. It provides meaningful explanations for all 5 parameters, clarifying formats (e.g., 'provider:model'), defaults, and interactions (e.g., output_path overrides output_extension). This adds substantial value beyond the bare schema, though some details like file path validation are missing.

  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's purpose with specific verbs ('read', 'send', 'write') and resources ('prompt from a file', 'multiple LLM models', 'responses to files'). It distinguishes itself from sibling tools like 'prompt_from_file_tool' by specifying multi-model processing and file output, avoiding tautology.

  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 for batch processing prompts through multiple models, but lacks explicit guidance on when to use this tool versus alternatives like 'prompt_tool' or 'prompt_from_file_tool'. No exclusions or prerequisites are mentioned, leaving usage context partially unclear.

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

• prompt_toolA
  3.8/5.0
  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 discloses the basic behavior (sending prompts and returning responses) but lacks critical details such as rate limits, authentication needs, error handling, response formats beyond 'List of responses', or whether this is a read-only or mutating operation. For a tool with no annotation coverage, 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?

  The description is front-loaded with the core purpose, followed by structured Args and Returns sections. Each sentence earns its place by providing necessary information without redundancy, making it efficient and well-organized.

  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 annotations and no output schema, the description covers parameters well but lacks behavioral context (e.g., how responses are structured, error cases). It is complete enough for basic use but misses details needed for robust agent interaction, especially for a tool with multiple parameters and no structured output definition.

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

  Parameters5/5

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

  With 0% schema description coverage, the description fully compensates by explaining both parameters: 'text' as 'The prompt text to send to the models' and 'models_prefixed_by_provider' with format details and a default value. This adds essential meaning beyond the bare 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?

  The description clearly states the specific action ('Send a text prompt to multiple LLM models') and resource ('return their responses'), distinguishing it from siblings like prompt_from_file_tool (which uses file input) and list_models_tool (which lists models rather than sending prompts). The verb 'send' and scope 'multiple LLM models' are precise.

  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 by specifying default behavior ('If None, defaults to ["openai:gpt-4o-mini"]'), but it does not explicitly state when to use this tool versus alternatives like prompt_from_file_tool or persona tools. No exclusions or prerequisites are mentioned, leaving some ambiguity.

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