Tool Scores

• copilot_chatC
  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 'Chats with GitHub Copilot AI models' but doesn't mention any behavioral traits such as rate limits, authentication requirements, response formats, or potential side effects (e.g., whether it's read-only or can modify data). This is a significant gap for a tool with no 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 a single, efficient sentence that front-loads the core purpose ('Chat with GitHub Copilot AI models') and adds a clarifying phrase ('for general programming assistance'). There is no wasted wording, making it highly concise and well-structured.

  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 complexity of an AI chat tool with 4 parameters, no annotations, and no output schema, the description is incomplete. It lacks details on behavioral traits (e.g., how responses are formatted, any limitations), doesn't differentiate from siblings, and provides minimal context beyond the basic purpose, leaving gaps for effective tool selection and invocation.

  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 parameters (message, context, model, temperature). The description adds no parameter-specific information beyond what's in the schema, such as examples or usage tips. The baseline score of 3 reflects adequate coverage by the schema alone.

  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 ('Chat with') and resource ('GitHub Copilot AI models'), specifying it's for 'general programming assistance'. However, it doesn't distinguish this from sibling tools like copilot_explain, copilot_review, or copilot_suggest, which likely serve more specific programming assistance purposes.

  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 its siblings (copilot_explain, copilot_review, copilot_suggest). It mentions 'general programming assistance' but doesn't clarify what constitutes 'general' versus the more specialized purposes implied by the sibling names, leaving the agent to guess about appropriate contexts.

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

• copilot_explainC
  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 the tool 'gets' explanations, implying a read-only operation, but doesn't cover aspects like rate limits, authentication needs, response format, or potential errors. 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 a single, clear sentence with zero waste—it directly states the tool's purpose without unnecessary elaboration. It's appropriately sized and front-loaded, making it easy for an agent 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 complexity of explaining code and the lack of annotations and output schema, the description is insufficient. It doesn't address what the explanations include, how they're formatted, or any limitations, leaving the agent with incomplete context for effective tool invocation.

  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%, meaning all parameters are documented in the schema. The description adds no additional meaning beyond what's in the schema (e.g., it doesn't clarify what 'detailed explanations' entail or how context influences results). Baseline 3 is appropriate as the schema handles parameter documentation adequately.

  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 detailed explanations') and the resource ('code from GitHub Copilot'), making the purpose evident. However, it doesn't explicitly differentiate from sibling tools like copilot_chat or copilot_review, which might also involve explanations or discussions about code.

  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 copilot_chat or copilot_review. It lacks any mention of specific contexts, prerequisites, or exclusions, leaving the agent to infer usage based on tool names alone.

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

• copilot_reviewC
  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 'Get[s] code review and improvement suggestions,' which implies a read-only operation, but doesn't clarify if it modifies data, requires authentication, has rate limits, or what the output format is. For a tool with no annotations, this leaves significant behavioral gaps.

  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, clear sentence: 'Get code review and improvement suggestions from GitHub Copilot.' It's front-loaded with the core purpose, has zero waste, and is appropriately sized for the tool's complexity. Every word earns its place.

  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 annotations and no output schema, the description is incomplete. It doesn't explain what the tool returns (e.g., structured feedback, suggestions list), potential errors, or behavioral traits like response format. For a tool with 3 parameters and no structured output, more context is needed to guide effective use.

  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 already documents all parameters (code, language, reviewType) with descriptions and constraints. The description adds no additional parameter semantics beyond what's in the schema, such as examples or usage tips. Baseline 3 is appropriate as the schema handles the heavy lifting.

  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 code review and improvement suggestions from GitHub Copilot.' It specifies the verb ('Get') and resource ('code review and improvement suggestions'), and distinguishes it from siblings by focusing on review rather than chat, explanation, or suggestion. However, it doesn't explicitly differentiate from siblings like 'copilot_suggest' which might overlap in providing suggestions.

  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 (copilot_chat, copilot_explain, copilot_suggest) or specify scenarios where this review tool is preferred over others, such as for security checks versus general coding help. Usage is implied but not explicitly defined.

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

• copilot_suggestC
  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 mentions 'suggestions and completions' but fails to detail critical aspects such as rate limits, authentication requirements, response format, or potential side effects. This is a significant gap for a tool interacting with an external AI service.

  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 that directly states the tool's function without unnecessary words. It is front-loaded and wastes no space, making it easy for an agent 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 complexity of interacting with GitHub Copilot, no annotations, and no output schema, the description is insufficient. It lacks details on behavioral traits, error handling, and return values, leaving the agent with incomplete information for reliable tool invocation.

  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 input schema has 100% description coverage, clearly documenting all four parameters. The description adds no additional meaning beyond the schema, such as examples or usage tips. However, since the schema is comprehensive, a baseline score of 3 is appropriate as the description doesn't need to compensate for gaps.

  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 as 'Get code suggestions and completions from GitHub Copilot', specifying the action ('Get') and resource ('code suggestions and completions'). It distinguishes from sibling tools like copilot_chat, copilot_explain, and copilot_review by focusing on generation rather than conversation, explanation, or review, though it doesn't explicitly contrast them.

  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 copilot_chat or copilot_explain. It lacks context about specific scenarios, prerequisites, or exclusions, leaving the agent to infer usage based on the name and purpose alone.

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