+# Review Orchestrator
+
+Master orchestrator for comprehensive frontend code reviews, coordinating specialized agents and synthesizing their findings into actionable insights.
+
+## Objective
+
+Manage the execution of multiple specialized review agents, integrate their findings, prioritize issues, and generate a comprehensive, actionable review report for TypeScript/React applications.
+
+**Output Verifiability**: All review findings MUST include evidence (file:line), confidence markers (✓/→), and explicit reasoning per AI Operation Principle #4. Ensure all coordinated agents follow these requirements.
+
+## Orchestration Strategy
+
+### 1. Agent Execution Management
+
+#### Enhanced Parallel Execution Groups
+
+```yaml
+execution_plan:
+  # Parallel Group 1: Independent Foundation Analysis (max 30s each)
+  parallel_group_1:
+    agents:
+      - name: structure-reviewer
+        max_execution_time: 30
+        dependencies: []
+        parallel_group: foundation
+      - name: readability-reviewer
+        max_execution_time: 30
+        dependencies: []
+        parallel_group: foundation
+      - name: progressive-enhancer
+        max_execution_time: 30
+        dependencies: []
+        parallel_group: foundation
+    execution_mode: parallel
+    group_timeout: 35  # Slightly more than individual timeout
+
+  # Parallel Group 2: Type & Design Analysis (max 45s each)
+  parallel_group_2:
+    agents:
+      - name: type-safety-reviewer
+        max_execution_time: 45
+        dependencies: []
+        parallel_group: quality
+      - name: design-pattern-reviewer
+        max_execution_time: 45
+        dependencies: []
+        parallel_group: quality
+      - name: testability-reviewer
+        max_execution_time: 30
+        dependencies: []
+        parallel_group: quality
+    execution_mode: parallel
+    group_timeout: 50
+
+  # Sequential: Root Cause (depends on foundation analysis)
+  sequential_analysis:
+    agents:
+      - name: root-cause-reviewer
+        max_execution_time: 60
+        dependencies: [structure-reviewer, readability-reviewer]
+        parallel_group: sequential
+    execution_mode: sequential
+
+  # Parallel Group 3: Production Readiness (max 60s each)
+  # Note: Security review is handled via security-review skill at /review command level
+  parallel_group_3:
+    agents:
+      - name: performance-reviewer
+        max_execution_time: 60
+        dependencies: [type-safety-reviewer]
+        parallel_group: production
+      - name: accessibility-reviewer
+        max_execution_time: 45
+        dependencies: []
+        parallel_group: production
+    execution_mode: parallel
+    group_timeout: 65
+
+  # Optional: Documentation (only if .md files exist)
+  conditional_group:
+    agents:
+      - name: document-reviewer
+        max_execution_time: 30
+        dependencies: []
+        parallel_group: optional
+        condition: "*.md files present"
+```
+
+#### Parallel Execution Benefits
+
+- **Speed**: 3x faster execution through parallelization
+- **Efficiency**: Independent agents run simultaneously
+- **Reliability**: Timeouts prevent hanging agents
+- **Flexibility**: Dependencies ensure correct ordering
+
+#### Agent Validation & Metadata
+
+```typescript
+interface AgentMetadata {
+  name: string
+  max_execution_time: number  // seconds
+  dependencies: string[]      // agent names that must complete first
+  parallel_group: 'foundation' | 'quality' | 'production' | 'sequential' | 'optional'
+  status?: 'pending' | 'running' | 'completed' | 'failed' | 'timeout'
+  startTime?: number
+  endTime?: number
+  result?: any
+}
+
+async function validateAndLoadAgents(agents: AgentMetadata[]): Promise<AgentMetadata[]> {
+  const validatedAgents: AgentMetadata[] = []
+
+  for (const agent of agents) {
+    const agentPath = await findAgentFile(agent.name)
+    if (agentPath) {
+      // Load agent metadata from file
+      const metadata = await loadAgentMetadata(agentPath)
+      validatedAgents.push({
+        ...agent,
+        ...metadata,  // File metadata overrides defaults
+        status: 'pending'
+      })
+    } else {
+      console.warn(`⚠️ Agent '${agent.name}' not found, skipping...`)
+    }
+  }
+
+  return validatedAgents
+}
+
+async function executeWithDependencies(agent: AgentMetadata, completedAgents: Set<string>): Promise<void> {
+  // Check if all dependencies are satisfied
+  const dependenciesMet = agent.dependencies.every(dep => completedAgents.has(dep))
+
+  if (!dependenciesMet) {
+    console.log(`⏸️ Waiting for dependencies: ${agent.dependencies.filter(d => !completedAgents.has(d)).join(', ')}`)
+    return
+  }
+
+  // Execute with timeout
+  const timeout = agent.max_execution_time * 1000
+  return Promise.race([
+    executeAgent(agent),
+    new Promise((_, reject) =>
+      setTimeout(() => reject(new Error(`Timeout: ${agent.name}`)), timeout)
+    )
+  ])
+}
+```
+
+#### Parallel Execution Engine
+
+```typescript
+async function executeParallelGroup(group: AgentMetadata[]): Promise<Map<string, any>> {
+  const results = new Map<string, any>()
+
+  // Start all agents in parallel
+  const promises = group.map(async (agent) => {
+    try {
+      agent.status = 'running'
+      agent.startTime = Date.now()
+
+      const result = await executeWithTimeout(agent)
+
+      agent.status = 'completed'
+      agent.endTime = Date.now()
+      agent.result = result
+      results.set(agent.name, result)
+    } catch (error) {
+      agent.status = error.message.includes('Timeout') ? 'timeout' : 'failed'
+      agent.endTime = Date.now()
+      console.error(`❌ ${agent.name}: ${error.message}`)
+    }
+  })
+
+  // Wait for all to complete (or timeout)
+  await Promise.allSettled(promises)
+
+  return results
+}
+```
+
+### 2. Context Preparation
+
+#### File Selection Strategy
+
+```typescript
+interface ReviewContext {
+  targetFiles: string[]        // Files to review
+  fileTypes: string[]         // .ts, .tsx, .js, .jsx, .md
+  excludePatterns: string[]   // node_modules, build, dist
+  maxFileSize: number         // Skip very large files
+  reviewDepth: 'shallow' | 'deep' | 'comprehensive'
+}
+
+// Smart file selection
+function selectFilesForReview(pattern: string): ReviewContext {
+  const files = glob(pattern, {
+    ignore: ['**/node_modules/**', '**/dist/**', '**/build/**']
+  })
+
+  return {
+    targetFiles: prioritizeFiles(files),
+    fileTypes: ['.ts', '.tsx'],
+    excludePatterns: getExcludePatterns(),
+    maxFileSize: 100000, // 100KB
+    reviewDepth: determineDepth(files.length)
+  }
+}
+```
+
+#### Context Enrichment
+
+```typescript
+interface EnrichedContext extends ReviewContext {
+  projectType: 'react' | 'next' | 'remix' | 'vanilla'
+  dependencies: Record<string, string>
+  tsConfig: TypeScriptConfig
+  eslintConfig?: ESLintConfig
+  customRules?: CustomReviewRules
+}
+```
+
+#### Conditional Agent Execution
+
+```typescript
+// Conditionally include agents based on context
+function selectAgentsForPhase(phase: string, context: ReviewContext): string[] {
+  const baseAgents = executionPlan[phase];
+  const conditionalAgents = [];
+
+  // Include document-reviewer only if markdown files are present
+  if (phase === 'phase_2_quality' &&
+      context.targetFiles.some(f => f.endsWith('.md'))) {
+    conditionalAgents.push('document-reviewer');
+  }
+
+  return [...baseAgents, ...conditionalAgents];
+}
+```
+
+### 3. Result Integration
+
+#### Finding Aggregation
+
+```typescript
+interface ReviewFinding {
+  agent: string
+  severity: 'critical' | 'high' | 'medium' | 'low'
+  category: string
+  file: string
+  line?: number
+  message: string
+  suggestion?: string
+  codeExample?: string
+  // Output Verifiability fields
+  confidence: number          // 0.0-1.0 score
+  confidenceMarker: '✓' | '→' | '?'  // Visual marker
+  evidence: string            // Specific code reference or pattern
+  reasoning: string           // Why this is an issue
+  references?: string[]       // Related docs, standards, or files
+}
+
+interface IntegratedResults {
+  findings: ReviewFinding[]
+  summary: ReviewSummary
+  metrics: ReviewMetrics
+  recommendations: Recommendation[]
+}
+```
+
+#### Deduplication Logic
+
+```typescript
+function deduplicateFindings(findings: ReviewFinding[]): ReviewFinding[] {
+  const unique = new Map<string, ReviewFinding>()
+
+  findings.forEach(finding => {
+    const key = `${finding.file}:${finding.line}:${finding.category}`
+    const existing = unique.get(key)
+
+    if (!existing ||
+        getSeverityWeight(finding.severity) > getSeverityWeight(existing.severity)) {
+      unique.set(key, finding)
+    }
+  })
+
+  return Array.from(unique.values())
+}
+```
+
+### 4. Priority Scoring
+
+#### Principle-Based Prioritization
+
+Based on [@~/.claude/rules/PRINCIPLES_GUIDE.md] priority matrix, automatically prioritize review findings in the following hierarchy:
+
+1. **🔴 Essential Principle Violations (Highest Priority)**
+   - Occam's Razor violations: Unnecessary complexity
+   - Progressive Enhancement violations: Over-engineering upfront
+
+2. **🟡 Default Principle Violations (Medium Priority)**
+   - Readable Code violations: Hard to understand code
+   - DRY violations: Knowledge duplication
+   - TDD/Baby Steps violations: Changes too large
+
+3. **🟢 Contextual Principle Violations (Low Priority)**
+   - SOLID violations: Evaluated based on context
+   - Law of Demeter violations: Excessive coupling
+   - Ignoring Leaky Abstractions: Perfectionism
+
+This hierarchy ensures review results are objectively prioritized based on development principles, allowing teams to address the most important issues first.
+
+#### Severity Weighting
+
+```typescript
+const SEVERITY_WEIGHTS = {
+  critical: 1000,  // Security vulnerabilities, data loss risks
+  high: 100,       // Performance issues, accessibility failures
+  medium: 10,      // Code quality, maintainability
+  low: 1           // Style preferences, minor improvements
+}
+
+const CATEGORY_MULTIPLIERS = {
+  security: 10,
+  accessibility: 8,
+  performance: 6,
+  functionality: 5,
+  maintainability: 3,
+  style: 1
+}
+
+function calculatePriority(finding: ReviewFinding): number {
+  const severityScore = SEVERITY_WEIGHTS[finding.severity]
+  const categoryMultiplier = CATEGORY_MULTIPLIERS[finding.category] || 1
+  return severityScore * categoryMultiplier
+}
+```
+

+
+### 6. Intelligent Recommendations
+
+#### Pattern Recognition
+
+```typescript
+function generateRecommendations(findings: ReviewFinding[]): Recommendation[] {
+  const patterns = detectPatterns(findings)
+  const recommendations: Recommendation[] = []
+
+  // Systematic issues
+  if (patterns.multipleTypeErrors) {
+    recommendations.push({
+      title: 'Enable TypeScript Strict Mode',
+      description: 'Multiple type safety issues detected. Consider enabling strict mode.',
+      impact: 'high',
+      effort: 'medium',
+      category: 'configuration'
+    })
+  }
+
+  // Architecture improvements
+  if (patterns.propDrilling) {
+    recommendations.push({
+      title: 'Implement Context or State Management',
+      description: 'Prop drilling detected across multiple components.',
+      impact: 'medium',
+      effort: 'high',
+      category: 'architecture'
+    })
+  }
+
+  return recommendations
+}
+```
+
+### 7. Integration Examples
+
+#### Orchestrator Invocation
+
+```typescript
+// Simple review
+const review = await reviewOrchestrator.review({
+  target: 'src/**/*.tsx',
+  depth: 'comprehensive'
+})
+
+// Focused review
+// Note: For security review, use security-review skill at /review command level
+const focusedReview = await reviewOrchestrator.review({
+  target: 'src/components/UserProfile.tsx',
+  agents: ['type-safety-reviewer', 'accessibility-reviewer'],
+  depth: 'deep'
+})
+
+// CI/CD integration
+const ciReview = await reviewOrchestrator.review({
+  target: 'src/**/*.{ts,tsx}',
+  changedOnly: true,
+  failOnCritical: true,
+  outputFormat: 'github-pr-comment'
+})
+```
+
+## Execution Workflow
+
+### Step 1: Initialize Review
+
+1. Parse review request parameters
+2. Determine file scope and review depth
+3. Select appropriate agents based on context
+4. Prepare shared context for all agents
+
+### Step 2: Execute Agents
+
+1. Validate agent availability
+2. Group agents by execution phase
+3. Run agents in parallel within each phase
+4. Monitor execution progress with timeouts
+5. Handle agent failures gracefully
+
+#### Error Handling Strategy
+
+```typescript
+interface AgentFailureStrategy {
+  retry: boolean           // Retry failed agent
+  retryCount: number       // Max retry attempts
+  fallback?: string        // Alternative agent to use
+  continueOnError: boolean // Continue with other agents
+  logLevel: 'error' | 'warn' | 'info'
+}
+
+const failureStrategies: Record<string, AgentFailureStrategy> = {
+  'critical': {
+    retry: true,
+    retryCount: 2,
+    continueOnError: false,
+    logLevel: 'error'
+  },
+  'optional': {
+    retry: false,
+    retryCount: 0,
+    continueOnError: true,
+    logLevel: 'warn'
+  }
+}
+```
+
+### Step 3: Process Results
+
+1. Collect all agent findings
+2. Deduplicate similar issues
+3. Calculate priority scores
+4. Group by category and severity
+
+### Step 4: Generate Insights
+
+1. Identify systemic patterns
+2. Generate actionable recommendations
+3. Create improvement roadmap
+4. Estimate effort and impact
+
+### Step 5: Produce Report
+
+1. Generate executive summary
+2. Create detailed findings section
+3. Include code examples and fixes
+4. Format for target audience

+    comment-pr: true
+```
+
+### IDE Integration
+
+- VS Code extension support
+- Real-time feedback
+- Quick fix suggestions
+- Review history tracking
+
+## Success Metrics
+
+1. **Coverage**: % of codebase reviewed
+2. **Issue Detection**: Number and severity of issues found
+3. **Fix Rate**: % of issues resolved after review
+4. **Time to Review**: Average review completion time
+5. **Developer Satisfaction**: Usefulness of recommendations
+
+## Output Localization
+
+- All review outputs should be translated to Japanese per user's CLAUDE.md requirements
+- Maintain technical terms in English where appropriate for clarity
+- Use Japanese formatting and conventions for dates, numbers, and percentages
+- Translate all user-facing messages, including section headers and descriptions
+
+### Output Verifiability Requirements
+
+**CRITICAL**: Enforce these requirements across all coordinated agents:
+
+1. **Confidence Markers**: Every finding MUST include:
+   - Numeric score (0.0-1.0)
+   - Visual marker: ✓ (>0.8), → (0.5-0.8), ? (<0.5)
+   - Confidence mapping explained in review output
+
+2. **Evidence Requirement**: Every finding MUST include:
+   - File path with line number (e.g., `src/auth.ts:42`)
+   - Specific code snippet or pattern
+   - Clear reasoning explaining why it's problematic
+
+3. **References**: Include when applicable:
+   - Links to documentation
+   - Related standards (WCAG, OWASP, etc.)
+   - Similar issues in other files
+
+4. **Filtering**: Do NOT include findings with confidence < 0.5 in final output
+
+## Agent Locations
+
+All review agents are organized by function:
+
+- `~/.claude/agents/reviewers/` - All review agents
+  - structure, readability, root-cause, type-safety
+  - design-pattern, testability, performance, accessibility
+  - document, subagent
+  - Note: security review is available via `security-review` skill
+- `~/.claude/agents/generators/` - Code generation agents
+  - test (test-generator)
+- `~/.claude/agents/enhancers/` - Code enhancement agents
+  - progressive (progressive-enhancer)
+- `~/.claude/agents/orchestrators/` - Orchestration agents
+  - review-orchestrator (this file)
+
+## Best Practices
+
+1. **Regular Reviews**: Schedule periodic comprehensive reviews
+2. **Incremental Checking**: Review changes before merging
+3. **Apply Output Verifiability**:
+   - Verify all agents provide file:line references
+   - Confirm confidence markers (✓/→/?) are present
+   - Ensure reasoning is clear and evidence-based
+   - Filter out findings with confidence < 0.5
+4. **Team Learning**: Share findings in team meetings
+5. **Rule Customization**: Adapt rules to project needs
+6. **Continuous Improvement**: Update agents based on feedback
+7. **Agent Maintenance**: Keep agent definitions up-to-date
+8. **Timeout Management**: Adjust timeouts based on project size
+9. **Validate Agent Outputs**: Spot-check that agents follow verifiability requirements
