Expo Architect

Create production-ready Expo React Native apps with:

• Framework: Expo SDK 54 + React Native 0.83 + TypeScript
• Navigation: Expo Router (file-based routing)
• Auth: Clerk authentication (optional)
• UI: NativeWind (Tailwind for RN) or StyleSheet
• Quality: Biome linting + TypeScript strict mode
• Package Manager: bun

What Makes This Different

Generates working mobile apps, not empty scaffolds:

• Complete navigation structure with working screens
• Optional Clerk authentication flow
• Real UI components with proper styling
• API client integration ready
• Runs immediately with bun start

Workflow Summary

1. PRD Brief Intake - Extract app type, screens, features, auth needs
2. Auth Setup (if requested) - Clerk provider, sign-in/sign-up screens
3. Screen Generation - Tab or stack-based navigation
4. Component Generation - UI components, entity components, layouts
5. Quality Setup - Biome, TypeScript strict, path aliases
6. Verification - Run quality gate, report results

Usage

# Create app with PRD-style prompt
python3 scripts/init-expo.py \
  --root ~/www/myapp \
  --name "My App" \
  --brief "A fitness tracker where users can log workouts"

# With specific options
python3 scripts/init-expo.py \
  --root ~/www/myapp \
  --name "My App" \
  --tabs "Home,Workouts,Profile" \
  --auth
