🔄 Workflow Details

🎯 /plan-product (NEW!)

Product Discovery & Planning - Platform-agnostic.

/plan-product I want to build a habit tracker app

What it does:

  1. Vision Clarification - Understand product goals
  2. Feature Engineering - MVP prioritization (MoSCoW)
  3. Screen Mapping - UI inventory with navigation
  4. Technical Architecture - Stack recommendations
  5. Development Roadmap - Sprint planning
  6. Memory Storage - PRD saved for reference

Output: Comprehensive Product Requirements Document (PRD)

Next Step: Run /feature-flutter or /feature-reactnative

🎯 /feature-flutter & /feature-reactnative

Full Feature Implementation with enterprise-grade quality.

/feature-flutter Add user authentication with biometric support

What it does:

  1. Phase -1: Auto-detect PRD from /plan-product (if exists)
  2. Phase 0: Auto-detect Google Stitch designs (optional)
  3. Phase 1: Grand Architect planning
  4. Phase 2: Security audit (OWASP, JWT)
  5. Phase 3: Implementation
  6. Phase 4: Quality assurance (5 agents parallel)
  7. Phase 5: Test generation + documentation

Output: Complete feature + security review + tests + docs

🔍 /review-flutter & /review-reactnative

Comprehensive Code Review with parallel execution.

/review-flutter Review the authentication module

What it does (in parallel ⚡):

  • 🎨 Design token compliance
  • ♿ Accessibility audit (WCAG 2.2)
  • 🔐 Security vulnerability scan
  • ⚡ Performance analysis
  • 🧪 Test coverage check

Output: Review report with scores + actionable fixes

🧪 /test-flutter & /test-reactnative

Test Suite Generation with ROI-based prioritization.

/test-flutter Generate tests for CheckoutScreen

What it does:

  • Widget/Component tests
  • Unit tests for logic
  • Integration tests
  • State management tests
  • API mocking patterns
  • CI/CD pipeline setup

Output: Complete test suite + GitHub Actions config

🎨 /stitch-flutter & /stitch-reactnative (NEW!)

Convert Google Stitch HTML designs to native code.

/stitch-flutter ./stitch_my_project

What it does:

  1. Read all code.html files from Stitch folder
  2. Extract design tokens (colors, typography, spacing)
  3. Generate theme files
  4. Convert HTML → native widgets/components
  5. Generate navigation setup
  6. Run quality checks

Output:

  • Screens in lib/screens/ or src/screens/
  • Reusable widgets/components
  • Theme files (colors, typography)
  • Basic tests

Auto-detection: Feature workflows (/feature-*) automatically detect stitch_* folders and use them as design foundation!
