• generate_qa_summaryB
  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 must carry the full burden. It lists what the summary contains, but does not disclose side effects, whether it writes to disk, required permissions, or what happens if the report is missing. This is insufficient for a tool that produces an advisory recommendation.

  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, focused sentence that front-loads the primary action and enumerates the key output components. No wasted words or redundant details.

  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?

  With one well-documented parameter and no output schema, the description covers the high-level purpose and output contents. However, it lacks behavioral details like prerequisites, expected input format, or how the advisory recommendation is determined, which would be useful for complete 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?

  Schema coverage is 100% since reportPath has a clear description. The tool description adds no extra parameter information beyond what the schema already provides, so it meets the baseline for high schema coverage.

  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 generates a complete QA execution summary with specific components (metrics, failure analysis, quality risks, Markdown output, advisory release recommendation). It is distinct enough from siblings but does not explicitly differentiate itself, so it misses the top score.

  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?

  Usage is implied: the user provides a report path and expects a summary. However, there is no explicit guidance on when to use this tool versus alternatives like get_test_run_summary or analyze_test_failures, and no exclusions or prerequisites are mentioned.

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

• analyze_test_failuresA
  3.5/5.0
  Behavior2/5

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

  With no annotations, the description is solely responsible for behavioral transparency. It only states that it analyzes and groups, without disclosing output format, prerequisites, side effects, or error behavior. The term 'approved' suggests a constraint but is not explained, leaving a meaningful transparency gap for a tool that produces a categorized analysis.

  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, front-loaded sentence that packs the core action, input, and outcome without any filler. Every word adds value, making it highly 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?

  No output schema is present, so the description should explain the return value. It hints at the result ('group them by probable failure category') but does not specify the structure of the output, potential edge cases (e.g., no failures), or how 'approved' is determined. For a tool with one parameter and no nested objects, this is a moderate completeness gap.

  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 covers the single parameter fully with a clear description ('Path to the report relative to the approved reports directory, such as json/playwright-results.json.'), earning a baseline of 3. The description's mention of 'approved Playwright JSON report' aligns with the schema but adds no extra semantic detail beyond what is already provided.

  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 ('Analyze'), the resource ('failed, timed-out, and flaky tests from an approved Playwright JSON report'), and the outcome ('group them by probable failure category'). This sharply distinguishes it from sibling tools like list_test_runs or generate_bug_report.

  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 an approved Playwright report with failures that need categorizing, but it avoids explicit alternatives or exclusions. It doesn't mention when to choose this over generate_bug_report or get_test_run_summary, leaving the agent to infer based on the tool name and purpose.

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

• generate_bug_reportA
  3.7/5.0
  Behavior2/5

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

  With no annotations provided, the description must carry the full burden of behavioral disclosure. It mentions the output is a 'draft' and requires an 'approved' report, but does not disclose whether the operation is read-only, if any resources are modified, what permissions are needed, or the exact return format. For a generation tool, this is a significant gap.

  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, focused sentence with no redundant words. It efficiently conveys the tool's purpose, input requirements, and output type without adding unnecessary detail.

  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 explains the tool's purpose and input source but does not elaborate on the output format or any side effects, which is important given the absence of an output schema and annotations. While the tool is relatively simple with only two parameters, the description leaves room for ambiguity about the exact return value and the workflow context (e.g., that it follows failure analysis).

  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 provides full descriptions for both parameters (reportPath and testId), so the baseline is 3. The description does not add any extra meaning or constraints beyond what the schema already states, but it does align with the schema by referencing 'approved Playwright JSON report' and 'test'.

  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 function with a specific verb ('Generate') and resource ('structured draft bug report'), and defines the scope ('one failed, timed-out, or flaky test from an approved Playwright JSON report'). It is easily distinguishable from sibling tools like 'analyze_test_failures' and 'generate_qa_summary'.

  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 provides clear context for when to use the tool: for a single test from an approved Playwright report. However, it does not explicitly mention when not to use it or name alternatives, so it lacks the explicit exclusions or alternative guidance that would warrant a 5.

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

• get_test_run_summaryA
  3.8/5.0
  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 conveys that the operation is read-only ('Read') and that it computes metrics, which implies non-destructive behavior. However, it does not mention potential error conditions (e.g., invalid path, unapproved report), return format, or whether it accesses external resources beyond the file. The 'approved' adjective adds some context but is vague.

  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, well-structured sentence that front-loads the action ('Read an approved Playwright JSON report') and immediately enumerates the computed metrics. Every word adds value; there is no redundancy or filler.

  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?

  For a tool with one parameter and no output schema, the description is nearly complete. It states the input (report path), the action (read), and the output (metrics). It could be improved by specifying that the metrics are returned in a structured format or mentioning any prerequisites, but the current level is sufficient for a straightforward reporting tool.

  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% and the parameter description explicitly explains the path format and location ('relative to the approved reports directory, such as json/playwright-results.json'). The tool description does not add further parameter meaning, but with perfect schema coverage the baseline of 3 is appropriate.

  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 ('Read an approved Playwright JSON report') and the intended outcome ('calculate pass, failure, skip, timeout, and flaky-test metrics'). This distinguishes it from sibling tools: list_test_runs lists runs, analyze_test_failures focuses on failures, and generate_qa_summary generates a summary. The unique resource ('Playwright JSON report') and metric list make the purpose unmistakable.

  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?

  Usage is implied by the description: use this tool when you have an approved Playwright JSON report and need high-level metrics. However, it does not explicitly state when to use it instead of siblings (e.g., list_test_runs for listing, analyze_test_failures for failure analysis) or provide any exclusion criteria. The 'approved' qualifier hints at a prerequisite but is not elaborated.

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

• list_test_runsA
  4/5.0
  Behavior3/5

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

  With no annotations, the description must carry the burden of behavioral disclosure. It states the tool reads from a specific directory and filters by file type, implying a read-only operation. However, it does not mention whether the list is sorted, what happens if no files are found, or any access restrictions besides 'approved'. This is adequate but not rich.

  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, front-loaded sentence that gets straight to the point: 'Find available Playwright JSON and JUnit test-result files in the approved reports directory.' No redundancy or fluff; every word contributes.

  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?

  For a simple parameterless list tool, the description is complete enough. It specifies the exact files sought and the directory. Without an output schema, it could benefit from mentioning the return format (e.g., list of paths), but for a 'find' operation the output is reasonably inferable. The context of sibling tools suggests it is a discovery step, which is adequately conveyed.

  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 zero parameters, so the baseline is 4. The description adds no parameter-specific semantics because there are none to explain. It briefly hints at the scope (directory) but does not need to elaborate further.

  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 function: 'Find available Playwright JSON and JUnit test-result files in the approved reports directory.' The verb 'find' plus the specific resource (test-result files) and location (approved reports directory) fully distinguish it from sibling tools like get_test_run_summary or analyze_test_failures, which serve 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: it is for locating available test result files before running analyses or summaries. However, it does not explicitly mention when to prefer this over siblings or provide exclusions. Given the sibling tools exist, some guidance on 'use this to discover files before invoking summary/analysis' would have been helpful.

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