Tool Scores

• chatC
  2.3/5.0
  Behavior2/5

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

  With no annotations, the description must disclose all behavioral traits. It only states the action without mentioning side effects, idempotency, rate limits, or authentication needs. Minimal transparency.

  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 a single short sentence, but it omits critical information. It is under-specified rather than concise. Every sentence should add value, but here it fails to cover essential aspects.

  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?

  Given the complexity (nested objects, 3 parameters, no output schema, no annotations), the description is vastly insufficient. It does not explain return values, error handling, or how to structure the messages array. Completely inadequate for effective tool usage.

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

  Parameters1/5

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

  The description adds no information about the parameters (model, messages, options). Schema coverage is 0%, and the description does not compensate by explaining what these parameters mean or how to use them. The agent gets no help beyond parameter names.

  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: sending a chat completion request to Ollama. It specifies the verb 'send' and the resource 'chat completion request'. However, it does not differentiate from the sibling tool 'generate', which might have a similar purpose, reducing clarity.

  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 guidelines on when to use this tool versus alternatives like 'generate' or other sibling tools. The description lacks context for appropriate usage scenarios, exclusions, or prerequisites.

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

• get_metricsC
  2.3/5.0
  Behavior1/5

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

  No annotations provided, and the description gives no behavioral traits (e.g., read-only, rate limits, data scope). The description carries full burden but fails to disclose any behavioral context.

  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?

  At three words, it is very concise but lacks necessary detail. Could be more informative while remaining brief.

  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?

  With no output schema, no annotations, and a minimal description, the tool definition is incomplete. It does not explain what the metrics represent, possible return values, or side effects.

  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% (no parameters), baseline is 3. Description adds no parameter-specific meaning beyond 'metrics', but no parameters exist to describe.

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

  Purpose3/5

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

  The description 'Get server metrics' is a clear verb+resource, but it is vague about what specific metrics and which server, and does not distinguish from siblings like chat or list_models.

  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. Context signals show siblings are unrelated, but description implies no specific context for use.

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

• generateC
  2.5/5.0
  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 only says 'generate text', omitting any details about side effects, required prerequisites, rate limits, or return behavior. This is insufficient for a tool that likely performs an important operation.

  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 it is too short to provide the necessary information for a tool with three parameters and no other documentation. Conciseness should not sacrifice completeness.

  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 is extremely incomplete. It lacks any explanation of parameters, output format, usage context, or behavior. With no output schema and no parameter descriptions, the agent cannot reliably invoke this tool. This is a critical gap.

  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%, meaning the input schema provides no explanations for the three parameters (model, prompt, options). The description does not compensate by explaining what these parameters do or how they affect generation. The agent is left guessing parameter semantics.

  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 'Generate text using Ollama' clearly states the verb 'generate' and the resource 'text using Ollama', making the purpose understandable. However, it does not differentiate from sibling tool 'chat' which also generates text, so it gets a 4 instead of 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?

  No guidance is provided on when to use this tool vs alternatives like 'chat'. The description does not mention use cases or when not to use this tool, leaving the agent without decision support.

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

• list_modelsB
  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 bears the full burden of behavioral disclosure. It only says 'List available models' with no mention of sorting, filtering, rate limits, or any side effects. For a zero-parameter tool, minimal transparency is acceptable, but the description adds no value beyond the name.

  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 extremely concise—one short phrase. It is front-loaded and easy to parse. However, it could be slightly more structured (e.g., 'Lists all models that are currently available for use.') without losing conciseness.

  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 no output schema, the description should explain what the return value contains. It does not. For a listing operation, users need to know if it returns model IDs, names, metadata, etc. The description is incomplete for a tool with no output 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?

  There are zero parameters, so the baseline score is 4. The description adds meaning by specifying that the tool lists 'available models', which clarifies what is returned. No additional parameter details are needed.

  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') and resource ('available models'). It is a specific verb+resource pair. However, it does not differentiate from sibling tools like 'get_account_status' or 'get_metrics', which also retrieve information. Still, the purpose is clear.

  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. There is no mention of context, prerequisites, or when not to use it. As a simple listing tool, it might be self-evident, but the absence of any usage instructions lowers the score.

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

• get_account_statusA
  3.5/5.0
  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 authentication requirements, potential errors, or the format of the status output. It only states the basic function.

  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 without unnecessary words. However, it could be slightly expanded for clarity.

  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?

  The description lacks details about the return value or what constitutes 'account status'. With no output schema, the agent is left guessing the response format.

  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?

  No parameters exist, so schema coverage is complete. The description adds value by specifying 'current active' state, which is 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?

  The description clearly states the action (Get) and the resource (current active account status), distinguishing it from sibling tools like chat, generate, etc.

  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, but the simple nature implies it can be called to check account status. The lack of parameters makes usage straightforward.

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