Code Review: Onboarding Wizard PR

Overview

This is an impressively comprehensive PR adding a sophisticated onboarding wizard system to Maestro. The implementation quality is generally excellent with strong architecture, comprehensive testing, and good attention to accessibility and user experience.

✅ Strengths

1. Excellent Architecture

• Clean state management with well-structured reducer pattern in WizardContext.tsx
• Separation of concerns: Business logic properly separated into service modules
• Reusable components: Modal system integrates cleanly with existing LayerStack infrastructure

2. Security Considerations

✅ Filename sanitization (phaseGenerator.ts:92-106) properly prevents path traversal attacks
✅ No shell injection: Correctly uses execFileNoThrow for external commands

3. Comprehensive Testing

• 1,474 lines of unit tests for WizardContext
• 1,413 lines of integration tests
• 684 lines of keyboard navigation tests
• 825 lines of structured output parser tests
• Tests cover edge cases, error handling, and accessibility

4. Accessibility

• Screen reader announcements
• ARIA labels and roles throughout
• Keyboard navigation with focus management
• Respects prefers-reduced-motion

5. Documentation

• Extensive inline JSDoc comments
• 111 lines added to CLAUDE.md with architecture overview and customization points

🔍 Areas for Improvement

1. Potential Memory Leak ⚠️

Location: conversationManager.ts

The conversation manager stores cleanup functions but review if dataListenerCleanup, exitListenerCleanup, and responseTimeoutId are always properly cleared in all code paths.

Recommendation: Add comprehensive cleanup check in endConversation() to ensure no hanging listeners or timers.

2. Error Handling in State Persistence

Location: WizardContext.tsx:701-705

The fire-and-forget pattern for saving wizard state means save failures are silently ignored, potentially losing user progress.

Recommendation: Add error handling with logging for failed saves.

3. Hardcoded Timeout Values

Location: phaseGenerator.ts:111

5-minute timeout might be too short for complex projects. No UI feedback when approaching timeout.

Recommendation: Make timeout configurable via settings and add progress indicator.

4. Response Parser Fallback Logic

Location: wizardPrompts.ts:320-366

Heuristic regex patterns for extracting confidence could match false positives.

Recommendation: Add more context validation and log when fallback parsing is used.

5. Missing Input Validation

Location: WizardContext.tsx:560-571

Agent name input lacks validation for empty/whitespace-only names, special characters, and very long names.

Recommendation: Add validation with max length (100 chars) and character restrictions.

6. Race Condition Potential

Location: MaestroWizard.tsx:176-194

Rapid navigation could cause visual glitches in transition animations.

Recommendation: Add debouncing or disable navigation buttons during transitions.

🐛 Potential Bugs

1. Directory Validation Race

If a directory is deleted externally after selection but before proceeding, the wizard might crash.

Recommendation: Add filesystem checks before each step transition requiring directory access.

📊 Performance Considerations

Positive:

• ✅ Efficient state updates with useMemo and useCallback
• ✅ Progressive loading for large session lists
• ✅ Stats caching

Could Improve:

• Conversation history kept in memory - for very long sessions, consider pagination

🔐 Security Assessment

Overall: Good ✅

• Filename sanitization properly implemented
• No shell injection vulnerabilities
• No obvious XSS vectors
• File I/O properly scoped

Minor note: Wizard system prompt is user-controllable (via project name). Ensure prompt injection mitigations are in place at the AI agent level.

📝 Code Style & Best Practices

Excellent adherence to project conventions:

• ✅ Follows CLAUDE.md standardized vernacular
• ✅ Uses theme colors via inline styles
• ✅ Proper TypeScript typing throughout
• ✅ Consistent commit message format
• ✅ Layer stack integration for modals

🎯 Test Coverage Assessment

Coverage is exemplary:

• State management: ✅ Comprehensive
• UI interactions: ✅ Keyboard navigation covered
• Edge cases: ✅ Error states tested
• Integration: ✅ Multi-screen flows tested
• Accessibility: ✅ ARIA and screen reader tested

💭 Suggestions for Follow-up Work

1. Analytics Dashboard: Implement dashboard to track wizard completion rates
2. Wizard Templates: Pre-fill conversation for common project types
3. Configurable Thresholds: Make confidence threshold and timeouts configurable

🎉 Final Verdict

Recommendation: APPROVE ✅

This is high-quality work with solid architecture, comprehensive testing, good security practices, excellent documentation, and thoughtful UX with accessibility considerations.

The issues identified are relatively minor and could be addressed in follow-up PRs. None are blocking. The wizard will significantly improve the onboarding experience for new users.

Estimated Risk Level: Low
Estimated User Impact: High positive impact

Great work on this feature! 🎼

PR Review: Onboarding Wizard

This is an exceptionally well-executed feature implementation. The onboarding wizard is comprehensive, well-architected, and demonstrates excellent engineering practices throughout. I've conducted a thorough review and have organized my feedback into categories below.

---

✅ Strengths

Architecture & Design

• Clean state management: The WizardContext using useReducer pattern is textbook React - centralized state with pure reducer functions and well-defined action types
• Excellent separation of concerns: Each service (conversationManager, phaseGenerator, wizardPrompts) has a single, clear responsibility
• Proper abstraction layers: IPC calls are properly isolated, business logic separated from UI components
• Singleton pattern: Appropriate use for conversationManager and phaseGenerator to manage global resources

Security

• Path traversal protection: sanitizeFilename() in phaseGenerator.ts:93-107 properly strips dangerous characters (path separators, null bytes, control chars, directory traversal sequences)
• Input validation: Wizard validates user input at each step before allowing progression
• No command injection risks: Process spawning uses structured arguments, not shell interpolation

Code Quality

• Comprehensive testing: 1,474 lines of WizardContext tests, 825 lines of prompt parser tests, integration tests, keyboard navigation tests, theme tests - this is exemplary test coverage
• TypeScript excellence: Well-defined interfaces, proper type safety, discriminated unions for action types
• Documentation: Excellent JSDoc comments explaining complex logic, especially in the conversation and phase generation services
• Error handling: Proper try-catch blocks, user-friendly error messages, graceful degradation

User Experience

• Accessibility: Screen reader announcements, ARIA labels, keyboard navigation, focus management, layer stack integration
• Progressive enhancement: Resume functionality with state persistence, graceful handling of missing data
• Visual feedback: Confidence meter, progress dots, loading states, animations respecting prefers-reduced-motion
• Smart timeouts: 5-minute timeout with activity-based reset - timeout only fires after inactivity, not total time

Performance

• Efficient re-renders: Proper use of useMemo, useCallback, ref-based callbacks to avoid unnecessary updates
• Streaming responses: Real-time chunk processing with --include-partial-messages flag for better UX
• Resource cleanup: Proper listener cleanup in useEffect return functions and class cleanup methods

---

🔍 Areas for Improvement

1. Security Enhancement (Minor)

Location: phaseGenerator.ts:812-816

The filename sanitization could be more robust. If sanitization returns empty string (edge case), we'd get ".md" or "document.md". The current implementation already has a fallback to 'document' in sanitizeFilename, so this is a very low severity issue.

Severity: Low

---

2. Memory Management

Location: conversationManager.ts:272-365, phaseGenerator.ts:536-728

Issue: Both managers accumulate output in outputBuffer without size limits. For extremely verbose AI responses (multi-MB outputs), this could cause memory issues.

Recommendation: Consider adding a buffer size limit (e.g., 10MB) with truncation warning.

Severity: Low (unlikely in practice, but good defensive programming)

---

3. Race Condition Potential

Location: conversationManager.ts:300-332 (exit listener)

Issue: The exit listener checks sessionId === this.session?.sessionId, but this.session could theoretically be mutated between the check and the cleanup.

Recommendation: Capture session reference at listener setup to compare against a const rather than a mutable object property.

Severity: Low (unlikely to manifest, but cleaner pattern)

---

4. Timeout Configuration

Location: conversationManager.ts:275, phaseGenerator.ts:112

Issue: Hard-coded 5-minute timeout might be insufficient for complex projects or slower systems. The timeout is also not user-configurable.

Recommendation:

• Extract to a constant with comment explaining the rationale
• Consider making it configurable via settings for power users
• Add a progress indicator showing time remaining

Severity: Low (5 minutes is generous for most cases)

---

5. Error Message Improvements

Location: Various conversationManager.ts and phaseGenerator.ts error returns

Issue: Some errors don't suggest next steps to the user (e.g., "Agent X is not available" could suggest checking installation).

Severity: Low (UX polish)

---

6. Console Logging in Production

Location: Throughout wizard files (40+ console.log statements)

Issue: Console logs in production can expose internal state and clutter browser console.

Recommendation: Use the existing window.maestro.logger from preload or wrap in debug flags.

Severity: Low (common practice, but could be cleaner)

---

7. Type Safety Improvement

Location: conversationManager.ts:264, phaseGenerator.ts:530

Issue: agent parameter typed as any loses type safety.

Recommendation: Import and use AgentConfig type instead of any.

Severity: Low (works fine, but TypeScript best practice)

---

📚 Documentation & Best Practices

Excellent Documentation

• The additions to CLAUDE.md are comprehensive and well-structured
• The "Onboarding Wizard" section provides clear guidance on architecture, customization, and state management
• Inline comments explain complex logic (especially in the parser fallback strategies)

Code Organization

• File structure follows established patterns
• Barrel exports (index.ts files) keep imports clean
• Screen components properly separated from business logic

Testing Philosophy

• Unit tests cover edge cases (unicode, malformed JSON, empty inputs)
• Integration tests verify multi-step flows
• Accessibility tests ensure keyboard navigation and screen readers work
• Mock setup is clean and reusable

---

🔒 Security Deep Dive

I specifically looked for common vulnerabilities:

✅ Path Traversal: Properly mitigated in sanitizeFilename
✅ Command Injection: Uses args array, not shell strings
✅ XSS: React escapes content by default
✅ Arbitrary Code Execution: No eval, Function, or unsafe deserialization
✅ Denial of Service: Timeouts prevent infinite hangs
✅ Resource Exhaustion: Process cleanup prevents zombie processes

One consideration: The AI-generated content in Phase documents is trusted implicitly. If an attacker could influence the AI's responses, they could potentially inject malicious markdown. However, this is more of an AI security concern than a code security issue.

---

🧪 Test Coverage Analysis

Based on the test files I reviewed:

• WizardContext: ✅ Excellent (all reducer actions, navigation, validation, persistence)
• wizardPrompts: ✅ Excellent (all parsing strategies, edge cases, fallbacks)
• Integration tests: ✅ Present (multi-step flow verification)
• Keyboard navigation: ✅ Present (accessibility)
• Theme styling: ✅ Present (visual consistency)

Missing tests (nice-to-haves):

• conversationManager.ts - Could benefit from unit tests for timeout logic, buffer management
• phaseGenerator.ts - Could test document parsing edge cases, file I/O mocking

Severity: Low (integration tests likely cover these paths)

---

📊 Performance Considerations

Strengths

• Minimal re-renders through proper memoization
• Efficient context updates (only changed values trigger updates)
• Streaming responses prevent blocking UI
• Activity-based timeout (smart!)

Potential Improvements

• Consider virtualizing conversation history if it grows very large (unlikely but possible)

---

🎨 UI/UX Observations

Animations

• Fade transitions with prefers-reduced-motion support - excellent accessibility
• Directional slide animations (forward/backward) - nice touch
• Progress dots clickable for completed steps - intuitive

Visual Feedback

• Confidence meter with color gradient (red→yellow→green) - clear visual indicator
• Loading states with spinner - user knows something is happening
• File creation notifications - satisfying immediate feedback

Edge Case Handling

• Resume modal when incomplete wizard detected - thoughtful UX
• Exit confirmation only after step 1 - doesn't annoy users who change their mind
• "Continue" vs "Start Fresh" for existing docs - respects user intent

---

🔄 Comparison to CLAUDE.md Standards

The PR adheres to all documented standards:

✅ Security Requirements: Follows secure patterns throughout
✅ Settings Persistence: Properly implements the useSettings pattern
✅ Modal Management: Correctly integrates with LayerStack and modal priorities
✅ Theme Colors: Uses inline styles for theme colors, not Tailwind classes
✅ TypeScript: Strict mode compliant, proper interfaces
✅ Commit Messages: PR description shows proper conventional commit format

• Fallback parsing strategies for malformed agent responses
• Document validation with quality checks
• File system watcher for detecting agent-created files

🔍 Issues & Recommendations

Critical: Security

1. No XSS Protection in Markdown Rendering ⚠️

• Location: PhaseReviewScreen.tsx (markdown content is user-controllable via AI)
• Issue: AI-generated markdown content is rendered without sanitization
• Risk: If agent generates malicious markdown/HTML, it could execute scripts
• Fix: Configure react-markdown with disallowedElements

// Recommended approach in PhaseReviewScreen
import ReactMarkdown from 'react-markdown';

<ReactMarkdown
  disallowedElements={['script', 'iframe', 'object', 'embed']}
  unwrapDisallowed={true}
>
  {content}
</ReactMarkdown>

High: Performance

2. Timeout Reset on Every Data Chunk Could Be Expensive

• Location: phaseGenerator.ts:575-599
• Issue: clearTimeout + setTimeout on every chunk could be inefficient for large outputs
• Impact: Hundreds or thousands of chunks might cause performance degradation
• Fix: Debounce the timeout reset with a timestamp check

// Instead of resetting on every chunk:
const resetTimeout = () => {
  const now = Date.now();
  // Only reset if it has been > 1 second since last reset
  if (now - lastTimeoutReset < 1000) return;
  lastTimeoutReset = now;
  clearTimeout(timeoutId);
  timeoutId = setTimeout(/* ... */, GENERATION_TIMEOUT);
};

3. Conversation History Grows Unbounded

• Location: WizardContext.tsx:302-306
• Issue: Each message is appended without limit
• Impact: Memory could grow large for long conversations
• Fix: Consider a maximum conversation depth or trimming old messages

Medium: Code Quality

4. Magic String Session IDs

• Location: conversationManager.ts:104, phaseGenerator.ts:554
• Issue: Session IDs use substr which is deprecated
• Fix: Use substring instead

// Change this:
`wizard-${Date.now()}-${Math.random().toString(36).substr(2, 9)}`
// To this:
`wizard-${Date.now()}-${Math.random().toString(36).substring(2, 11)}`

5. Hard-coded Confidence Threshold

• Location: wizardPrompts.ts:98
• Issue: READY_CONFIDENCE_THRESHOLD = 80 is hard-coded in multiple places
• Impact: Difficult to tune or make configurable per agent type
• Recommendation: Consider making this configurable in agent settings

6. File Watcher Not Cleaned Up on Component Unmount

• Location: phaseGenerator.ts:676-715
• Issue: File watcher setup happens in async code, but cleanup might not run if component unmounts
• Fix: Ensure abort() is called in useEffect cleanup

Low: Best Practices

7. Console.log Statements in Production Code

• Locations: conversationManager.ts, phaseGenerator.ts (multiple)
• Issue: Extensive console.logging in production
• Fix: Use the logger utility from main/utils/logger.ts or remove debug logs

8. Empty Catch Blocks

• Location: phaseGenerator.ts:704, 713, 808
• Issue: Errors are silently swallowed
• Fix: Log errors even if you do not throw them

.catch((err) => {
  logger.warn('[PhaseGenerator] Error setting up folder watcher:', err);
});

9. Potential Race Condition in State Persistence

• Location: WizardContext.tsx:748-769
• Issue: Auto-save uses stateRef.current which could be stale if state updates rapidly
• Impact: Unlikely in practice but could lose some state updates
• Recommendation: Consider using the latest state from the effect dependency

Documentation

10. Excellent CLAUDE.md Integration ✅

• The PR includes comprehensive documentation in CLAUDE.md
• Wizard architecture, flow, and customization points are well-documented
• Good examples and troubleshooting guidance

📊 Statistics

• Files changed: 71
• Additions: 18,898 lines
• Deletions: 512 lines
• Test files: 5 comprehensive test suites
• New components: 20+ React components
• Services: 3 major service modules

🎯 Summary

This is high-quality work with excellent architecture and testing. The wizard system is well-designed and follows React/TypeScript best practices. The main concerns are:

1. Must fix: XSS protection for markdown rendering
2. Should fix: Performance optimization for timeout resets
3. Nice to have: Remove debug console.logs and improve error logging

🔴 Critical Issues (Must Fix Before Merge)

1. Race Condition in conversationManager.ts:272-333

Bug: this.session could be null between check and usage if endConversation() is called concurrently.

// Current code (UNSAFE):
this.session!.exitListenerCleanup = window.maestro.process.onExit(
  (sessionId: string, code: number) => {
    if (sessionId === this.session?.sessionId) {
      // this.session could be null here!
      clearTimeout(timeoutId);
      // ... more code accessing this.session
    }
  }
);

Fix: Capture session reference at function start:

private async spawnAgentForMessage(...): Promise<SendMessageResult> {
  const currentSession = this.session; // Capture reference
  if (!currentSession) {
    return { success: false, error: 'No active session' };
  }
  
  // Use currentSession throughout instead of this.session
  currentSession.exitListenerCleanup = window.maestro.process.onExit(
    (sessionId: string, code: number) => {
      if (sessionId === currentSession.sessionId) {
        clearTimeout(timeoutId);
        // ... use currentSession consistently
      }
    }
  );
}

Location: src/renderer/components/Wizard/services/conversationManager.ts:272-333

---

2. Missing Validation in loadResumeState (WizardContext.tsx:729-732)

Bug: Corrupted state could cause runtime errors because only currentStep is validated.

// Current code (INCOMPLETE):
if (state.currentStep && state.currentStep !== 'agent-selection') {
  return state;
}

Fix: Add comprehensive validation:

const loadResumeState = useCallback(async (): Promise<SerializableWizardState | null> => {
  try {
    const saved = await window.maestro.settings.get('wizardResumeState');
    if (saved && typeof saved === 'object') {
      const state = saved as SerializableWizardState;
      
      // Validate all required fields
      if (!state.currentStep || state.currentStep === 'agent-selection') {
        return null;
      }
      
      if (!state.selectedAgent || !state.agentName || !state.directoryPath) {
        console.warn('[Wizard] Incomplete resume state, discarding');
        return null;
      }
      
      return state;
    }
    return null;
  } catch {
    return null;
  }
}, []);

Location: src/renderer/components/Wizard/WizardContext.tsx:729-732

---

3. Progress Dots Accessibility Issue (MaestroWizard.tsx:371-406)

A11Y Bug: Disabled buttons have no tab focus. Non-navigable steps should not be buttons.

Current code:

<button
  disabled={!canNavigate}
  aria-label={`Step ${stepNum}${...}`}
>

Fix: Use conditional rendering:

{canNavigate ? (
  <button
    onClick={() => goToStep(targetStep)}
    aria-label={`Step ${stepNum} - ${stepName}${isCompleted ? ' (completed - click to go back)' : ''}`}
  >
    {/* button content */}
  </button>
) : (
  <div
    role="presentation"
    aria-label={`Step ${stepNum} - ${stepName}${isActive ? ' (current)' : ' (not yet available)'}`}
  >
    {/* same visual content */}
  </div>
)}

Location: src/renderer/components/Wizard/MaestroWizard.tsx:371-406

---

4. Missing Filename Length Limit (phaseGenerator.ts:140-160)

Security Enhancement: Current sanitization is excellent but should limit length to prevent filesystem issues.

export function sanitizeFilename(filename: string): string {
  let sanitized = filename
    .replace(/[\/\\]/g, '-')
    .replace(/\.\./g, '')
    .replace(/[\x00-\x1f\x7f]/g, '')
    .replace(/^\.+/, '')
    .trim();
  
  // Add this: Limit filename length to prevent filesystem issues
  if (sanitized.length > 255) {
    sanitized = sanitized.substring(0, 255);
  }
  
  return sanitized || 'document';
}

Location: src/renderer/components/Wizard/services/phaseGenerator.ts:140-160

---

5. Missing Unit Tests

Gap: No unit tests for critical async logic:

• conversationManager.ts - Complex async logic not unit tested
• phaseGenerator.ts - File generation logic not unit tested

Action Required: Add test files:

• src/__tests__/renderer/components/Wizard/services/conversationManager.test.ts
• src/__tests__/renderer/components/Wizard/services/phaseGenerator.test.ts

Focus on testing:

• Error recovery scenarios
• Timeout handling
• Cleanup on failure
• Concurrent operations

---

⚠️ Should Fix (Can be Follow-up PR)

6. Deprecated Method Usage

Location: WizardContext.tsx:491

// Replace .substr() with .slice()
return `msg-${Date.now()}-${Math.random().toString(36).slice(2, 11)}`;

7. Silent Error Swallowing

Location: phaseGenerator.ts:871-873

// Add error logging:
window.maestro.autorun.unwatchFolder(this.currentWatchPath).catch((err) => {
  console.warn('[PhaseGenerator] Failed to unwatch folder:', err);
});

8. Code Duplication

Location: App.tsx:4128-4158

handleWizardLaunchSession duplicates logic from handleCreateSession. Consider refactoring to share code.

9. No Retry Logic

Location: conversationManager.ts

Consider adding exponential backoff retry for transient AI failures.

10. Telemetry Gap

Location: wizardPrompts.ts:320-365

When JSON parsing falls back to defaults, add logging to track how often AI fails to follow format.

---

💡 Nice to Have (Future Enhancements)

• Add debouncing to file watcher (phaseGenerator.ts:709-779)
• Implement heartbeat for long-running operations (5-minute timeouts)
• Add user cancellation support for long operations
• Test concurrent wizard scenarios

Service Layer: conversationManager singleton with proper cleanup, wizardPrompts with 4 parsing fallback strategies, phaseGenerator with progress callbacks.

UI: Fade transitions (150ms/200ms), confidence meter with HSL gradient, streaming AI output.

---

Minor Suggestions

1. Magic Number Constants (Low Priority)

Extract timeouts in conversationManager.ts:283 and phaseGenerator.ts:165 as named constants for easier tuning.

2. Potential Race Condition (Medium Priority)

conversationManager.ts:290-333 - Event listeners set up before spawning. Verify onData/onExit register globally to prevent lost events.

3. Error Messaging (Low Priority)

conversationManager.ts:189-195 - Add user-friendly recovery steps when agent unavailable.

4. TypeScript Typing (Low Priority)

conversationManager.ts:264 - Type agent parameter as AgentConfig instead of any.

---

Performance

Excellent:

• Memoized context value
• Stable callbacks with useCallback
• Hardware-accelerated transitions

Minor (non-blocking):

• Consider virtualization if conversations exceed 50+ exchanges
• Auto-save could be debounced (likely unnecessary)

---

PR Review: Onboarding Wizard

This is an excellent and comprehensive implementation of the onboarding wizard feature. The code quality is high, architecture is well-thought-out, and the PR demonstrates best practices throughout.

---

✅ Strengths

1. Exceptional Architecture & Code Organization

• Clean separation of concerns: State management (WizardContext), UI (screens), services (conversation/phase generation), and tour system
• Reducer pattern with well-defined actions and immutable state updates
• Comprehensive TypeScript definitions, proper use of discriminated unions
• 20+ wizard components organized logically in subdirectories

2. Outstanding Test Coverage

The PR includes 6 comprehensive test files with 5,000+ lines:

• Unit tests for WizardContext state management (1,491 lines)
• Integration tests for wizard flow (1,418 lines)
• Keyboard navigation tests (684 lines)
• Theme styling tests (610 lines)
• Structured output parser tests (825 lines)
• Screen reader tests (170 lines)

This level of testing is exemplary and far exceeds typical PR standards.

3. Excellent Security Practices

• Filename sanitization (phaseGenerator.ts:146): Removes path traversal, null bytes, control chars
• No shell command injection: Proper IPC handlers and execFileNoThrow pattern
• Input validation for paths, agent availability, and state

4. Accessibility Features

• Screen reader announcements
• Proper ARIA labels and roles
• Keyboard navigation with layer stack integration
• Focus management and trap
• Reduced motion support (MaestroWizard.tsx:534-553)

5. User Experience Polish

• Smooth fade transitions with directional animations
• Clickable progress dots to navigate back
• Resume functionality for interrupted sessions
• Exit confirmation to prevent data loss
• Austin facts during loading states
• Confidence meter visualization

6. Documentation

• Comprehensive CLAUDE.md section
• Clear inline comments
• JSDoc on exported functions

---

🔍 Areas for Improvement

1. Magic Number Constants

The DEFAULT_CONFIDENCE (20) and READY_CONFIDENCE_THRESHOLD (80) could benefit from comments explaining why these specific values were chosen.

2. Error Handling Edge Cases

Consider what happens if the agent becomes unavailable mid-conversation. The code handles initial unavailability but may not gracefully handle agent crashes during active conversation. Add a heartbeat or status check mechanism.

3. Timeout Configuration

The 5-minute GENERATION_TIMEOUT is reasonable but consider making it configurable for very large codebases.

4. File I/O Validation

The Auto Run document saving should validate:

• Available disk space
• File permissions in target directory
• Proper cleanup if save fails midway

5. Memory Management

The wizard state includes full conversation history which could grow large. Consider:

• Limiting persisted conversation history to last N messages
• Compressing the saved state

6. Security Recommendations

• Rate limiting on wizard retries
• Content validation for generated docs (XSS via markdown)
• Path canonicalization for Auto Run docs folder (symlink attacks)

Comprehensive Code Review: PR #19 - Onboarding Wizard

This PR implements a complex onboarding wizard system with 20,659 additions across 80 files. The implementation demonstrates excellent architecture and engineering practices overall.

Overall Assessment

Code Quality: 4.5/5 - Excellent architecture and patterns
Security: 3.5/5 - Good fundamentals with critical fixes needed
Testing: 4/5 - Comprehensive coverage with some edge case gaps
Performance: 4/5 - Good optimization with minor buffer concerns
Accessibility: 5/5 - Excellent screen reader and keyboard support

Overall Recommendation: APPROVE WITH CHANGES

Critical Issues (Must Fix)

1. Path Traversal Protection - Incomplete Sanitization

Location: src/renderer/components/Wizard/services/phaseGenerator.ts:146-160
Issue: The sanitizeFilename() function can be bypassed with .... which becomes .. after one pass. Need iterative removal until no .. sequences remain.

2. JSON Parsing Without Size Limits

Location: src/renderer/components/Wizard/services/wizardPrompts.ts:219-284
Issue: Multiple JSON.parse() calls on potentially large AI responses could lead to memory exhaustion. Add 1MB size check before parsing.

3. Regex DoS Potential

Location: src/renderer/components/Wizard/services/phaseGenerator.ts:295,387
Issue: Complex regex patterns could be vulnerable to catastrophic backtracking. Add 10MB input size limits before regex processing.

High Priority Issues

• Unchecked Promise Rejection (phaseGenerator.ts:872): Silent error swallowing should log warnings
• Large Buffer Accumulation: Output buffers accumulate unbounded - add 5MB warning, 10MB hard limit
• Missing Test Coverage: No tests for timeouts, path traversal, large responses, partial failures

Excellent Practices Observed

Architecture

• Outstanding useReducer for wizard state management
• Clean UI/business logic separation
• Excellent TypeScript typing

Security

• No command injection vulnerabilities
• Proper array-based process spawning
• Secure IPC channels for file operations
• No innerHTML or eval() usage

React

• Excellent useEffect cleanup
• Proper useCallback/useMemo optimization
• Stable callback references with refs

Testing

• 1,491 lines of state management tests
• 825 lines of parser tests
• 1,418 lines of integration tests
• 684 lines of keyboard navigation tests
• 610 lines of theme styling tests

Accessibility

• Outstanding screen reader support
• Proper ARIA live regions
• Comprehensive keyboard navigation
• WCAG 2.1 compliant

Final Recommendation

This is high-quality, well-engineered code. The critical security issues are straightforward defensive programming additions (input validation, size limits) that should be added as safety measures.

Once path traversal protection is strengthened, JSON/regex size limits are added, and high-priority test gaps are filled, this will be production-ready.

Excellent work overall! The 34 atomic commits and comprehensive CLAUDE.md documentation follow project conventions perfectly.

Action Items

• Fix sanitizeFilename() with iterative .. removal
• Add size limits to parseStructuredOutput()
• Add size limits to parseGeneratedDocuments()
• Add buffer size monitoring
• Fix silent error swallowing (line 872)
• Add security edge case tests
• Add timeout behavior tests
• Add large response handling tests

🔍 Areas of Concern & Recommendations

1. Security Considerations

Command Injection Risk (Medium Priority) - In conversationManager.ts:339-351, directoryPath comes from user input and is passed as cwd. Ensure path traversal attacks are prevented by validating absolute paths and checking for path traversal sequences.

Prompt Injection (Low Priority) - In wizardPrompts.ts:106-204, system prompt includes user-provided agentName. Sanitize agentName to remove newlines and special characters.

2. Performance Optimization

Large Dependency Arrays (Low Priority) - In WizardContext.tsx:832-871, useMemo has 39 dependencies, defeating its purpose. Consider splitting into multiple contexts.

Memory Leak Potential (Medium Priority) - In conversationManager.ts:274-283, add an abort() method to ensure cleanup on unmount.

3. Code Quality

• Extract magic numbers (READY_CONFIDENCE_THRESHOLD, FADE_OUT_DURATION, timeout values) to named constants
• Improve error handling consistency (some functions swallow errors silently)
• Reduce use of non-null assertions in conversationManager.ts

4. Testing Gaps

Consider adding integration tests for error paths, E2E test for full wizard flow, and performance tests.

5. Documentation

Add a Troubleshooting section to CLAUDE.md explaining error recovery procedures.

---

📊 Metrics Summary

• Lines Added: 21,960 (Large but justified)
• Lines Deleted: 720 (Good refactoring)
• Test Cases: 62+ (Outstanding)
• Documentation: Comprehensive ✅
• Accessibility: WCAG 2.1 compliant ✅
• TypeScript Coverage: 100% ✅

---

🎬 Final Recommendation

APPROVE with minor suggestions

This is a production-ready feature with exceptional quality. The security concerns are minor and mostly preventative. The performance optimizations are nice-to-haves.

Suggested Priority for Follow-up:

1. High: Add input sanitization for directoryPath and agentName
2. Medium: Add cleanup for conversationManager on unmount
3. Low: Split WizardContext for performance
4. Low: Extract magic numbers to constants

Great work on this comprehensive feature! 🎉

Pull Request Review: Onboarding Wizard

This is a comprehensive onboarding wizard implementation with 21,982 additions across 85 files. The code demonstrates excellent architecture, strong test coverage, and attention to detail.

🟢 Strengths

1. Excellent Architecture & Code Organization

• Clean separation of concerns: State management (WizardContext), business logic (services/), UI (screens/)
• Robust state management with reducer pattern and comprehensive action types
• Modular design with self-contained wizard screens
• Reusable services: conversationManager and phaseGenerator are well-designed singletons

2. Outstanding Security Practices

✅ No XSS vulnerabilities: No usage of innerHTML or dangerouslySetInnerHTML
✅ No code injection risks: No eval(), Function(), or string-based timeouts
✅ Proper sanitization: sanitizeFilename() (line 146 in phaseGenerator.ts) prevents path traversal
✅ Safe process spawning: All agent execution through secure IPC bridge
✅ No shell injection: Uses structured args arrays

3. Comprehensive Test Coverage

• 19 test files covering critical functionality
• Tests include state management, output parsing, keyboard navigation, theme styling, integration tests
• Unit tests for edge cases: Parser handles malformed JSON, markdown code blocks, fallback scenarios

4. Excellent User Experience

• Accessibility: Screen reader announcements, ARIA labels, keyboard navigation
• Progressive disclosure with validation
• Visual feedback: Confidence meter (red → yellow → green)
• Resume functionality for incomplete wizards
• Animation polish with prefers-reduced-motion support

• Graceful degradation with fallback parsing
• File watching with retries for race conditions

6. Well-Documented Code

• Clear JSDoc comments
• Inline explanatory comments
• Extensive CLAUDE.md documentation

🟡 Areas for Improvement

1. Potential Memory Leak in Event Listeners

Location: conversationManager.ts:290-333

Issue: Cleanup depends on onExit firing. If exit event never fires, listeners remain attached.

Fix: Add explicit process kill in timeout handler (phaseGenerator already does this at line 627)

2. Race Condition in State Persistence

Location: WizardContext.tsx:751-772

Issue: Auto-save depends on state.currentStep but builds from stateRef.current. Rapid updates could cause inconsistent saved state.

Recommendation: Add debouncing

3. Overly Permissive Fallback Parsing

Location: wizardPrompts.ts:320-365

Issue: Fallback uses regex heuristics that could mask genuine AI failures.

Recommendation: Add usedFallback flag and show warning in UI

4. Insufficient Input Validation

Location: phaseGenerator.ts:145-160

Issue: No length limit or character whitelist. AI could generate very long filenames or special chars.

Recommendation: Add 200 char limit and whitelist safe characters

5. Hard-Coded Timeout Values

Issue: 300s timeout may be insufficient for large codebases

Recommendation: Make configurable via settings

6. Type Safety Issue

Location: phaseGenerator.ts:264, 584

Issue: Agent config typed as any

Recommendation: Use AgentConfig type

🐛 Potential Issues

Minor Issues

1. Conversation Manager: Session ID Matching

Location: conversationManager.ts:302-332

The exit listener has extensive logging for session ID mismatches, suggesting this might have been a source of bugs during development. Consider whether the logging is still needed or if it should be reduced for production.

exitListenerCleanup = window.maestro.process.onExit(
  (sessionId: string, code: number) => {
    console.log('[Wizard] Exit event received:', { receivedId: sessionId, expectedId: this.session?.sessionId, code });
    if (sessionId === this.session?.sessionId) {
      console.log('[Wizard] Session ID matched! Processing exit...');
      // ...
    } else {
      console.log('[Wizard] Session ID mismatch, ignoring exit event');
    }
  }
);

Recommendation: Remove verbose logging or move to debug level.

2. Timeout Handling Could Be More Robust

Location: conversationManager.ts:274-283

The 5-minute timeout for conversation responses logs the buffer length but doesn't provide recovery options to the user beyond an error message.

Recommendation: Consider adding a "Retry" button when timeouts occur, or allowing the user to cancel early.

3. Hardcoded Folder Name

Location: phaseGenerator.ts:137

export const AUTO_RUN_FOLDER_NAME = 'Auto Run Docs';

The folder name "Auto Run Docs" is hardcoded and contains a space, which can be problematic in some CLI environments.

Recommendation: Consider making this configurable in settings, or use a more CLI-friendly name like autorun-docs or phases.

4. Magic Numbers

Location: MaestroWizard.tsx:18-20

const FADE_OUT_DURATION = 150;
const FADE_IN_DURATION = 200;

Animation durations are hardcoded and duplicated in CSS animations.

Recommendation: Define these as CSS custom properties or move to a theme/constants file.

---

🚀 Performance Considerations

Good Performance Practices ✅

• Memoized context value in WizardContext prevents unnecessary re-renders
• Proper cleanup of event listeners and timeouts
• Efficient state updates using refs to avoid effect dependencies

Potential Optimizations

1. Large Conversation History

The full conversation history is rebuilt into a prompt string on each message send. For very long conversations, this could become inefficient.

Recommendation: Consider truncating very old messages or implementing a sliding window for context.

2. File Watching

Location: phaseGenerator.ts:871-874

The phase generator watches the Auto Run folder for changes during document generation. Ensure this watcher is properly cleaned up in all error paths.

---

🔍 Code Style & Best Practices

Excellent Patterns ✅

• Consistent error handling patterns
• Clear function naming (verb-noun pattern)
• Proper TypeScript discriminated unions for state
• Ref pattern for stable callbacks
• Custom hooks for reusable logic

Minor Style Notes

1. Long Functions

Some functions are quite long (e.g., ConversationScreen.tsx is 1,033 lines). While well-structured, consider extracting more sub-components.

2. Magic Strings

Tour step IDs and selectors are hardcoded strings. Consider using enums or constants for better refactoring safety.

---

📝 Documentation

• JSDoc comments on all major functions
• Clear interface definitions
• Inline comments explaining complex logic

Suggestions

• Add sequence diagrams for the conversation flow
• Document the state persistence format for debugging
• Add troubleshooting section for common wizard issues

---

🔐 Security Assessment

Good Security Practices ✅

• No shell injection: Uses proper IPC handlers, no shell execution in wizard code
• Input validation: User inputs are validated before use
• No eval or dynamic code: All code is static

No Security Concerns Found ✅

---

Pull Request Review: Onboarding Wizard

This is an impressive feature addition! The onboarding wizard is well-architected and thoroughly tested. Here's my detailed review:

---

✅ Strengths

Architecture & Design

• Excellent separation of concerns: Clean split between state management (WizardContext), orchestration (MaestroWizard), screens, and services
• Well-structured state management: The reducer pattern with useReducer is appropriate for this complex multi-step flow
• Comprehensive state persistence: Resume functionality is thoughtfully implemented with proper validation
• Accessibility-first approach: Screen reader announcements, ARIA labels, keyboard navigation, and reduced motion support

Code Quality

• Extensive test coverage: 6,525 lines of tests across unit, integration, keyboard navigation, and theme styling tests
• Type safety: Strong TypeScript usage throughout with well-defined interfaces
• Documentation: Excellent inline comments and clear function/component documentation
• Error handling: Robust error handling with fallback strategies (e.g., multiple parsing strategies in parseStructuredOutput)

Security

• Path sanitization: sanitizeFilename in phaseGenerator.ts:146-160 properly prevents path traversal attacks
• Safe command execution: Uses existing secure IPC patterns through window.maestro API
• Input validation: Directory validation, agent detection, and proper state validation throughout

User Experience

• Smart timeout handling: The phaseGenerator uses activity-based timeouts (resets on data chunks OR file changes), preventing false timeouts
• Progressive enhancement: Graceful fallbacks when parsing fails or agents behave unexpectedly
• Visual polish: Smooth transitions, progress indicators, and celebration modal for first completion

---

🔍 Areas for Improvement

1. Performance Considerations

Issue: Large useMemo dependency arrays in WizardContext.tsx:832-871

// 40 dependencies in this useMemo
useMemo(() => ({ ...40 functions }), [state, ...39 callbacks])

Impact: This will re-create the context value whenever ANY of the 40 dependencies change, potentially causing unnecessary re-renders in consumers.

Recommendation: Since all the callbacks are already wrapped in useCallback and memoized, you could split the context into two:

• One for state (changes frequently)
• One for methods (stable references)

Or simply ensure consumers use useCallback when using these methods to avoid re-renders.

---

2. Potential Memory Leak

Issue: conversationManager.ts:100 stores session state but cleanup may not always happen

// If component unmounts while agent is running, listeners may not clean up
private session: ConversationSession | null = null;

Recommendation:

• Add a cleanup method to the singleton that components can call in useEffect cleanup
• Consider using AbortController pattern for better cancellation support
• Ensure PhaseGenerator's abort() method (line 963) is called in component unmount

---

3. Race Condition Risk

Issue: phaseGenerator.ts:709-779 sets up file watcher asynchronously, but agent may finish before watcher is ready

// Promise.then() starts watcher, but agent may create files before this resolves
window.maestro.autorun.watchFolder(autoRunPath).then((result) => {
  // Watcher setup happens here
});

// Agent spawns immediately below
window.maestro.process.spawn({ ... })

Recommendation:

• Either await the watcher setup before spawning the agent
• Or scan the folder for existing files after watcher setup completes to catch any files created during the race window

---

4. Hardcoded Magic Numbers

Issue: Multiple timeout values scattered throughout

• conversationManager.ts:283: 300000 (5 minutes)
• phaseGenerator.ts:165: 300000 (5 minutes)
• MaestroWizard.tsx:18-20: 150, 200 (fade durations)

Recommendation: Extract to named constants at the top of files:

const CONVERSATION_TIMEOUT_MS = 5 * 60 * 1000; // 5 minutes
const GENERATION_TIMEOUT_MS = 5 * 60 * 1000;
const FADE_OUT_DURATION_MS = 150;
const FADE_IN_DURATION_MS = 200;

---

5. Error Message User Experience

Issue: Some technical error messages may confuse non-technical users

// conversationManager.ts:282
error: 'Response timeout - agent did not complete in time'

// phaseGenerator.ts:630
error: 'Generation timed out after 5 minutes of inactivity. Please try again.'

Recommendation: Add more helpful context:

error: 'The AI agent didn\'t respond in time. This can happen with complex projects. Try breaking your project description into smaller pieces, or try again.'

---

6. Input Validation Edge Case

Issue: wizardPrompts.ts:308-313 normalizes confidence but doesn't handle NaN or Infinity

confidence: Math.max(0, Math.min(100, Math.round(response.confidence)))

Recommendation:

const safeConfidence = Number.isFinite(response.confidence) 
  ? Math.max(0, Math.min(100, Math.round(response.confidence)))
  : 0;

---

7. Potential XSS in Markdown Rendering

Issue: If PhaseReviewScreen renders user-edited markdown without sanitization, there's potential for XSS

Question: How is the markdown rendered in PhaseReviewScreen? If using dangerouslySetInnerHTML or a markdown library, ensure proper sanitization.

Recommendation: Use a sanitization library like DOMPurify if rendering HTML from markdown.

---

8. Console Logging in Production

Issue: Extensive console.log statements throughout (e.g., conversationManager.ts:272, 302, phaseGenerator.ts:592-598)

Recommendation:

• Use the existing logger utility from src/main/utils/logger.ts
• Or wrap in a debug flag: if (process.env.NODE_ENV === 'development') console.log(...)

---

9. Insufficient Test Coverage Areas

While test coverage is generally excellent, I noticed:

• No tests for the file watcher race condition scenario
• No tests for very large conversation histories (performance testing)
• No tests for malformed file system responses from IPC

Recommendation: Add integration tests covering:

it('should handle files created before watcher is ready', async () => { ... })
it('should handle 100+ message conversation history', async () => { ... })
it('should gracefully handle file system errors during save', async () => { ... })

---

10. Documentation Improvement

Issue: CLAUDE.md has excellent wizard documentation, but missing:

• Error recovery procedures (what if wizard crashes mid-way?)
• Known limitations (e.g., maximum conversation length, supported project types)
• Troubleshooting guide for common issues

Recommendation: Add a "Troubleshooting" section:

### Wizard Troubleshooting

**Wizard stuck on "Generating documents"?**
- Check Auto Run Docs folder - files may already be created

🔴 Critical Security Issues

1. Path Traversal - Missing Sanitization (CRITICAL)

File: src/renderer/components/Wizard/services/phaseGenerator.ts:299

AI-generated filenames are not sanitized before being stored in state. While saveDocuments() sanitizes before writing, the unsanitized filenames exist in memory and could be used elsewhere.

// Line 299 - Missing sanitization
const parsed = parseGeneratedDocuments(currentOutput);
// Should be:
const parsed = parseGeneratedDocuments(currentOutput).map(doc => ({
  ...doc,
  filename: sanitizeFilename(doc.filename)
}));

Risk: AI could generate ../../etc/passwd.md which would be stored and potentially displayed to users.

Fix: Apply sanitizeFilename() immediately after parsing in parseGeneratedDocuments().

---

2. Path Validation Missing in Main Process (CRITICAL)

File: src/main/index.ts:1712-1758

Core file system IPC handlers lack path traversal protection:

// Line 1712 - NO PATH VALIDATION
ipcMain.handle('fs:readDir', async (_, dirPath: string) => {
  const entries = await fs.readdir(dirPath, { withFileTypes: true });

// Line 1722 - NO PATH VALIDATION  
ipcMain.handle('fs:readFile', async (_, filePath: string) => {
  const buffer = await fs.readFile(filePath);

Risk: Renderer process could read arbitrary files on the system.

Fix: Implement path validation to restrict operations to safe directories:

ipcMain.handle('fs:readDir', async (_, dirPath: string) => {
  // Validate path is within allowed directories (user home, projects, etc.)
  const resolvedPath = path.resolve(dirPath);
  if (!isPathAllowed(resolvedPath)) {
    throw new Error('Access denied');
  }
  const entries = await fs.readdir(resolvedPath, { withFileTypes: true });

---

3. Command Injection Risk in Process Spawning (HIGH)

File: src/renderer/components/Wizard/services/phaseGenerator.ts:786-794

While the main process uses execFileNoThrow properly, directory paths from user selection are passed without validation:

window.maestro.process.spawn({
  sessionId,
  toolType: config.agentType,
  cwd: config.directoryPath,  // User-selected, not validated
  command: agent.command,
  args: [...(agent.args || [])],
  prompt,
});

Fix: Add path validation before spawning:

// Validate directory path doesn't contain shell metacharacters
if (!path.isAbsolute(config.directoryPath) || /[;&|`$]/.test(config.directoryPath)) {
  throw new Error('Invalid directory path');
}

---

4. Memory Exhaustion - Unlimited Buffers (HIGH)

Files:

• src/renderer/components/Wizard/services/conversationManager.ts:293
• src/renderer/components/Wizard/services/phaseGenerator.ts:640

Both services accumulate output indefinitely without size limits:

this.outputBuffer += data;  // No size limit

Risk: Malicious or misbehaving AI agent could send gigabytes of output, causing browser crash.

Fix: Implement buffer size limits (similar to execFile.ts):

private readonly MAX_BUFFER_SIZE = 10 * 1024 * 1024; // 10MB

onData: (data: string) => {
  if (this.outputBuffer.length + data.length > this.MAX_BUFFER_SIZE) {
    this.cleanup();
    reject(new Error('Output buffer exceeded maximum size'));
    return;
  }
  this.outputBuffer += data;
}

---

5. XSS Risk in Message Display (MEDIUM)

File: src/renderer/components/Wizard/services/conversationManager.ts:345-354

Raw AI output is stored without sanitization:

if (!message) {
  message = rawText;  // Raw, unsanitized AI output
}

Impact: Depends on how messages are rendered. If using dangerouslySetInnerHTML, this is critical.

Fix: Verify that ConversationScreen.tsx properly escapes HTML when rendering messages. The markdown renderer should handle this, but confirm it's not using dangerouslySetInnerHTML.

---

⚠️ High Priority Issues

6. Memory Leak - Timeout Cleanup Broken (HIGH)

File: src/renderer/components/Wizard/screens/AgentSelectionScreen.tsx:191-205

Timeout cleanup function is returned from a callback, not a useEffect:

const handlePathChange = useCallback((e: React.ChangeEvent<HTMLInputElement>) => {
  const newPath = e.target.value;
  setDirectoryPath(newPath);

  if (newPath.trim()) {
    const timeoutId = setTimeout(() => {
      validateDirectory(newPath);
    }, 500);
    return () => clearTimeout(timeoutId); // ❌ This doesn't work in callbacks!

Fix: Use a ref to track and clear the timeout:

const debounceTimeoutRef = useRef<NodeJS.Timeout | null>(null);

const handlePathChange = useCallback((e: React.ChangeEvent<HTMLInputElement>) => {
  const newPath = e.target.value;
  setDirectoryPath(newPath);
  
  if (debounceTimeoutRef.current) {
    clearTimeout(debounceTimeoutRef.current);
  }

  if (newPath.trim()) {
    debounceTimeoutRef.current = setTimeout(() => {
      validateDirectory(newPath);
    }, 500);
  }
}, [setDirectoryPath, validateDirectory]);

---

7. Type Safety - Unsafe State Casting (MEDIUM)

File: src/renderer/components/Wizard/WizardContext.tsx:724-738

State restoration performs minimal validation before casting:

const saved = await window.maestro.settings.get('wizardResumeState');
if (saved && typeof saved === 'object') {
  const state = saved as SerializableWizardState;  // Unsafe cast

Risk: Corrupted or malicious state data could cause type errors.

Fix: Add schema validation (consider using Zod or JSON Schema):

const validateState = (obj: any): obj is SerializableWizardState => {
  return (
    obj &&
    typeof obj === 'object' &&
    typeof obj.currentStep === 'string' &&
    // ... validate all required fields
  );
};

if (saved && validateState(saved)) {
  return saved;
}

---

8. Web Server Security - Multiple Concerns (MEDIUM)

File: src/main/web-server.ts:260-691

Good token-based auth implementation, but several concerns:

1. No HTTPS - Security token transmitted in plaintext
2. Token in URL - Can leak in logs, browser history, referrer headers
3. No CSRF protection - POST endpoints don't validate CSRF tokens
4. No session timeout - Token valid until app restart

Recommendations:

• Implement TLS/HTTPS for production
• Move token to HTTP-only cookie or Authorization header
• Add CSRF tokens for POST requests
• Implement session timeout and rotation

---

🟡 Medium Priority Issues

9. Anti-Pattern - document.activeElement in Render (MEDIUM)

File: src/renderer/components/Wizard/screens/DirectorySelectionScreen.tsx:408-410

style={{
  borderColor: state.directoryError
    ? theme.colors.error
    : document.activeElement === inputRef.current  // ❌ Won't trigger re-renders
    ? theme.colors.accent
    : theme.colors.border,

Fix: Use focus state:

const [isFocused, setIsFocused] = useState(false);

<input
  onFocus={() => setIsFocused(true)}
  onBlur={() => setIsFocused(false)}
  style={{
    borderColor: state.directoryError
      ? theme.colors.error
      : isFocused ? theme.colors.accent : theme.colors.border,

---

10. Environment Variable Leakage (MEDIUM)

File: src/main/process-manager.ts:176-178

AI agents receive the full Electron process environment:

} else {
  ptyEnv = process.env; // Passes entire environment
}

Risk: Could leak sensitive environment variables (API keys, system config).

Fix: Filter to only pass necessary variables:

const allowedVars = ['HOME', 'USER', 'PATH', 'LANG', 'TERM'];
ptyEnv = Object.fromEntries(
  Object.entries(process.env)
    .filter(([key]) => allowedVars.includes(key))
);

🔵 Minor Issues & Suggestions

11. JSON Schema Validation (LOW)

File: src/renderer/components/Wizard/services/wizardPrompts.ts:249-263

Consider adding schema validation after JSON parsing to prevent prototype pollution and unexpected fields.

12. API Key Storage - No Encryption (INFO)

File: src/main/index.ts:70-87

API keys stored in plaintext. Consider using Electron's safeStorage API for sensitive data.

13. State Consolidation Opportunity (LOW)

File: src/renderer/components/Wizard/screens/ConversationScreen.tsx:356-376

Nine useState hooks could be consolidated into useReducer for better organization.

14. Error Handling Consistency (LOW)

Different files use different error patterns (throwing vs returning error objects). Consider standardizing.

---

📝 Test Coverage Assessment

Excellent coverage overall:

• ✅ WizardContext state management (1491 lines of tests)
• ✅ Integration tests for full wizard flow (1418 lines)
• ✅ Keyboard navigation tests (684 lines)
• ✅ Theme styling tests (610 lines)
• ✅ Structured output parser tests (829 lines)
• ✅ Accessibility tests (screen reader announcements)

Missing coverage:

• ❌ Security tests (path traversal, XSS payloads, sanitization edge cases)
• ❌ Buffer overflow tests (memory exhaustion scenarios)
• ❌ Race condition tests (rapid state changes, concurrent operations)

Recommendation: Add security-focused unit tests for sanitizeFilename(), path validation, and JSON parsing with malicious inputs.

Comprehensive Code Review: PR #19 - Onboarding Wizard

Executive Summary

This is an impressive PR adding ~23,000 lines across 90 files with strong architectural patterns, comprehensive testing, and thoughtful UX. However, there are critical security vulnerabilities that must be addressed before merging.

---

🔴 CRITICAL ISSUES (Must Fix Before Merge)

1. Path Traversal Vulnerability in phaseGenerator.ts

Location: src/renderer/components/Wizard/services/phaseGenerator.ts:146-160

The sanitizeFilename() function is vulnerable to path traversal attacks. An attacker could use encoded filenames to escape the Auto Run directory and write files elsewhere.

Fix: Add URL decoding, additional character filtering, length limits, and path validation at save time to ensure files stay within the intended directory.

2. Weak Random Number Generation

Location: WizardContext.tsx:491, conversationManager.ts:104

Math.random() is used for session IDs, which is not cryptographically secure and could enable session hijacking.

Fix: Use crypto.randomUUID() or the existing generateId() utility instead.

3. Race Condition in Async Operations

Location: conversationManager.ts:271-365, phaseGenerator.ts:600-810

Timeout and exit handlers can fire simultaneously, resolving promises twice.

Fix: Add a resolved flag to prevent double resolution.

---

🟡 HIGH PRIORITY ISSUES

4. Memory Leak in useEffect

Location: FirstRunCelebration.tsx:180-190, MaestroWizard.tsx

Event listeners are re-registered frequently due to unstable useEffect dependencies.

Fix: Use useRef pattern to stabilize callbacks.

5. No Progress Feedback for 5-Minute Timeouts

Users could wait 5 minutes with no feedback before getting a timeout error.

Fix: Add progress callbacks every 30 seconds and cancellation support.

6. Missing Input Validation on Paths

User-selected paths are used without validation (symlinks, network paths).

Fix: Validate paths are directories and resolve to absolute paths.

---

🟠 MEDIUM PRIORITY

7. Inefficient Re-renders

WizardContext includes full state object, breaking memoization.

8. Potential XSS in Markdown Preview

Malicious SVG images could execute scripts.

9. Silent Error Swallowing

Many catch blocks ignore errors without logging.

---

✅ EXCELLENT WORK

1. State Management - Proper reducer pattern with thorough testing
2. Test Coverage - 1,491 lines of comprehensive tests (exemplary!)
3. IPC Security - Correct use of execFileNoThrow throughout
4. Layer Stack - Perfect modal registration per CLAUDE.md
5. Documentation - Comprehensive inline docs and CLAUDE.md section

---

🎯 PERFORMANCE

• Large bundle size (23K+ lines) - recommend lazy loading
• Markdown rendering without memoization - add useMemo

---

📋 PRIORITY ACTIONS

P0 - Before Merge:

1. Fix path traversal in sanitizeFilename()
2. Replace Math.random() with crypto.randomUUID()
3. Fix async race conditions
4. Add path validation

P1 - Before Release:
5. Fix useEffect memory leaks
6. Add timeout progress feedback
7. Add error logging

P2 - Future:
8. Optimize context re-renders
9. Add lazy loading
10. Enhance accessibility

---

🎬 CONCLUSION

Outstanding feature with excellent architecture and testing. Code quality is high and follows project conventions well.

However: Critical security vulnerabilities must be fixed before merge (path traversal, weak RNG, race conditions).

Once P0 issues are resolved, this will be a stellar addition to the codebase.

Recommendation: Request changes for P0 security issues, then approve.

PR Review: Onboarding Wizard Feature

This is an impressive implementation adding 22,828 lines across 92 files with 56 commits.

Strengths

Architecture: Clean modular structure, robust useReducer state management with 28 actions, extensive useMemo/useCallback optimization (133+ occurrences)

Security: Excellent - sanitizeFilename() prevents path traversal, no command injection, safe IPC operations

Test Coverage: Outstanding - 6 test suites with 236+ cases covering state (91 tests), integration, keyboard (19 tests), themes (116 tests), parsing (89 tests), edge cases

Accessibility: Screen readers with ARIA live regions, full keyboard nav, proper ARIA labels, focus management, prefers-reduced-motion support

Performance: Smart 5-min inactivity timeouts with reset, streaming support, singletons, debounced saves

Documentation: 60+ lines in CLAUDE.md, well-commented code, JSDoc, excellent commits

Areas for Consideration

1. Error handling: Consider process exit monitoring for faster crash detection (conversationManager.ts:274)
2. Performance: Long conversations (20+ exchanges) create massive prompts - consider truncation (conversationManager.ts:242)
3. Race conditions: 200ms file retry may not suffice for large files - use exponential backoff (phaseGenerator.ts:735)
4. Validation: Warnings bypassed if content exists - log errors (phaseGenerator.ts:530)
5. Code duplication: extractResultFromStreamJson in both managers - extract to utility

Minor Improvements

• Magic numbers to constants (300000, 80, 150, 200)
• Replace any types with proper interfaces (phaseGenerator.ts:263)
• Solarized themes have lower contrast - consider warnings
