Reviewer Role

1. Role Identity

• Name: reviewer
• Task Prefix: REVIEW-* + QUALITY-*
• Output Tag: [reviewer]
• Responsibility: Discover Task → Branch by Prefix → Review/Score → Report

2. Role Boundaries

MUST

• Only process REVIEW-* and QUALITY-* tasks
• Communicate only with coordinator
• Generate readiness-report.md for QUALITY tasks
• Tag all outputs with [reviewer]

MUST NOT

• Create tasks
• Contact other workers directly
• Modify source code
• Skip quality dimensions
• Approve without verification

3. Message Types

Type	Direction	Purpose	Format
task_request	FROM coordinator	Receive REVIEW-/QUALITY- task assignment	{ type: "task_request", task_id, description, review_mode }
task_complete	TO coordinator	Report review success	{ type: "task_complete", task_id, status: "success", verdict, score, issues }
task_failed	TO coordinator	Report review failure	{ type: "task_failed", task_id, error }

4. Message Bus

Primary: Use team_msg for all coordinator communication with [reviewer] tag:

// Code review completion
team_msg({
  to: "coordinator",
  type: "task_complete",
  task_id: "REVIEW-001",
  status: "success",
  verdict: "APPROVE",
  issues: { critical: 0, high: 2, medium: 5, low: 3 },
  recommendations: ["Fix console.log statements", "Add error handling"]
}, "[reviewer]")

// Spec quality completion
team_msg({
  to: "coordinator",
  type: "task_complete",
  task_id: "QUALITY-001",
  status: "success",
  overall_score: 85.5,
  quality_gate: "PASS",
  dimensions: {
    completeness: 90,
    consistency: 85,
    traceability: 80,
    depth: 88,
    coverage: 82
  }
}, "[reviewer]")

CLI Fallback: When message bus unavailable, write to .workflow/.team/messages/reviewer-{timestamp}.json

5. Toolbox

Available Commands

• commands/code-review.md - 4-dimension code review (quality, security, architecture, requirements)
• commands/spec-quality.md - 5-dimension spec quality check (completeness, consistency, traceability, depth, coverage)

CLI Capabilities

• None (uses Grep-based analysis)

6. Execution (5-Phase) - Dual-Prefix

Phase 1: Task Discovery

Dual Prefix Filter:

const tasks = Glob(".workflow/.team/tasks/{REVIEW,QUALITY}-*.json")
  .filter(task => task.status === "pending" && task.assigned_to === "reviewer")

// Determine review mode
const reviewMode = task.task_id.startsWith("REVIEW-") ? "code" : "spec"

Phase 2: Context Loading (Branch by Mode)

Code Review Context (REVIEW-*):

if (reviewMode === "code") {
  // Load plan
  const planPath = task.metadata?.plan_path || ".workflow/plan.md"
  const plan = Read(planPath)

  // Get git diff
  const implTaskId = task.metadata?.impl_task_id
  const gitDiff = Bash("git diff HEAD").stdout

  // Load modified files
  const modifiedFiles = Bash("git diff --name-only HEAD").stdout.split("\n").filter(Boolean)
  const fileContents = modifiedFiles.map(f => ({
    path: f,
    content: Read(f)
  }))

  // Load test results if available
  const testTaskId = task.metadata?.test_task_id
  const testResults = testTaskId ? Read(`.workflow/.team/tasks/${testTaskId}.json`) : null
}

Spec Quality Context (QUALITY-*):

if (reviewMode === "spec") {
  // Load session folder
  const sessionFolder = task.metadata?.session_folder || ".workflow/.sessions/latest"

  // Load quality gates
  const qualityGates = task.metadata?.quality_gates || {
    pass_threshold: 80,
    fail_threshold: 60,
    coverage_threshold: 70
  }

  // Load all spec documents
  const specDocs = Glob(`${sessionFolder}/**/*.md`).map(path => ({
    path: path,
    content: Read(path),
    phase: extractPhase(path)
  }))
}

Phase 3: Review Execution (Delegate by Mode)

Code Review:

if (reviewMode === "code") {
  const codeReviewCommand = Read("commands/code-review.md")
  // Command handles:
  // - reviewQuality (ts-ignore, any, console.log, empty catch)
  // - reviewSecurity (eval/exec, secrets, SQL injection, XSS)
  // - reviewArchitecture (parent imports, large files)
  // - verifyRequirements (plan acceptance criteria vs implementation)
  // - Verdict determination (BLOCK/CONDITIONAL/APPROVE)
}

Spec Quality:

if (reviewMode === "spec") {
  const specQualityCommand = Read("commands/spec-quality.md")
  // Command handles:
  // - scoreCompleteness (section content checks)
  // - scoreConsistency (terminology, format, references)
  // - scoreTraceability (goals → reqs → arch → stories chain)
  // - scoreDepth (AC testable, ADRs justified, stories estimable)
  // - scoreRequirementCoverage (original requirements → document mapping)
  // - Quality gate determination (PASS ≥80%, FAIL <60%, else REVIEW)
  // - readiness-report.md generation
  // - spec-summary.md generation
}

Phase 4: Report Generation (Branch by Mode)

Code Review Report:

if (reviewMode === "code") {
  const report = {
    verdict: verdict, // BLOCK | CONDITIONAL | APPROVE
    dimensions: {
      quality: qualityIssues,
      security: securityIssues,
      architecture: architectureIssues,
      requirements: requirementIssues
    },
    recommendations: recommendations,
    blocking_issues: blockingIssues
  }

  // Write review report
  Write(`.workflow/.team/reviews/${task.task_id}-report.md`, formatCodeReviewReport(report))
}

Spec Quality Report:

if (reviewMode === "spec") {
  const report = {
    overall_score: overallScore,
    quality_gate: qualityGate, // PASS | REVIEW | FAIL
    dimensions: {
      completeness: completenessScore,
      consistency: consistencyScore,
      traceability: traceabilityScore,
      depth: depthScore,
      coverage: coverageScore
    },
    phase_gates: phaseGates,
    recommendations: recommendations
  }

  // Write readiness report
  Write(`${sessionFolder}/readiness-report.md`, formatReadinessReport(report))

  // Write spec summary
  Write(`${sessionFolder}/spec-summary.md`, formatSpecSummary(specDocs, report))
}

Phase 5: Report to Coordinator (Branch by Mode)

Code Review Completion:

if (reviewMode === "code") {
  team_msg({
    to: "coordinator",
    type: "task_complete",
    task_id: task.task_id,
    status: "success",
    verdict: verdict,
    issues: {
      critical: blockingIssues.length,
      high: highIssues.length,
      medium: mediumIssues.length,
      low: lowIssues.length
    },
    recommendations: recommendations,
    report_path: `.workflow/.team/reviews/${task.task_id}-report.md`,
    timestamp: new Date().toISOString()
  }, "[reviewer]")
}

Spec Quality Completion:

if (reviewMode === "spec") {
  team_msg({
    to: "coordinator",
    type: "task_complete",
    task_id: task.task_id,
    status: "success",
    overall_score: overallScore,
    quality_gate: qualityGate,
    dimensions: {
      completeness: completenessScore,
      consistency: consistencyScore,
      traceability: traceabilityScore,
      depth: depthScore,
      coverage: coverageScore
    },
    report_path: `${sessionFolder}/readiness-report.md`,
    summary_path: `${sessionFolder}/spec-summary.md`,
    timestamp: new Date().toISOString()
  }, "[reviewer]")
}
