# 🎨 UI Design Workflow with Triple Vision Analysis & Interactive Preview

This release introduces a comprehensive UI design workflow system with triple vision analysis capabilities, interactive user checkpoints, zero agent overhead, and enhanced preview tools for real-time prototype comparison.

## 🌟 Major Features

### UI Design Workflow System
- **`/workflow:design:auto`**: Semi-autonomous workflow orchestrator with interactive checkpoints
- **`/workflow:design:style-extract`**: Triple vision analysis (Claude Code + Gemini + Codex)
- **`/workflow:design:style-consolidate`**: Token validation and style guide generation
- **`/workflow:design:ui-generate`**: Token-driven HTML/CSS prototype generation with preview tools
- **`/workflow:design:design-update`**: Design system integration into brainstorming artifacts

### 👁️ Triple Vision Analysis
- **Claude Code**: Quick initial visual analysis using native Read tool
- **Gemini Vision**: Deep semantic understanding of design intent
- **Codex Vision**: Structured pattern recognition with -i parameter
- **Consensus Synthesis**: Weighted combination strategy for robust results

### ⏸️ Interactive Checkpoints
- **Checkpoint 1**: User selects preferred style variants after extraction
- **Checkpoint 2**: User confirms selected prototypes before design update
- Pause-and-continue pattern for critical design decisions

### 🌐 Preview Enhancement System (NEW!)
- **`index.html`**: Master preview navigation with grid layout
- **`compare.html`**: Side-by-side comparison with responsive viewport toggles
- **`PREVIEW.md`**: Comprehensive preview instructions and server setup guide
- Synchronized scrolling for layout comparison
- Dynamic page switching and real-time responsive testing

### 🎯 Zero Agent Overhead
- Removed Task(conceptual-planning-agent) wrappers from design commands
- Direct bash execution for gemini-wrapper and codex commands
- Improved performance while preserving all functionality

## 🚀 Quick Start

### Complete Design Workflow
```bash
# Semi-autonomous workflow with user checkpoints
/workflow:design:auto --session WFS-auth --images "design-refs/*.png" --pages "login,register" --batch-plan
```

### Individual Commands
```bash
# Extract design styles (triple vision analysis)
/workflow:design:style-extract --session WFS-auth --images "refs/*.png"

# Consolidate selected variants
/workflow:design:style-consolidate --session WFS-auth --variants "variant-1,variant-3"

# Generate prototypes with preview tools
/workflow:design:ui-generate --session WFS-auth --pages "login,register" --variants 2

# Preview generated prototypes
cd .workflow/WFS-auth/.design/prototypes
python -m http.server 8080  # Visit http://localhost:8080

# Integrate design system
/workflow:design:design-update --session WFS-auth --selected-prototypes "login-variant-1,register-variant-2"
```

## 🎨 Design System Features
- **OKLCH Color Format**: Perceptually uniform color space
- **W3C Design Tokens**: Standard-compliant token format
- **WCAG 2.1 AA Compliance**: Automated accessibility validation
- **Style Override Support**: Runtime token customization with --style-overrides
- **Batch Task Generation**: Automatic task creation with --batch-plan

## 📊 Preview Tools

### Master Navigation (index.html)
- Grid layout of all generated prototypes
- Quick links to individual variants
- Metadata display (session ID, timestamps, page info)
- Direct access to implementation notes

### Side-by-Side Comparison (compare.html)
- Iframe-based comparison for multiple variants
- Responsive viewport toggles:
  - Desktop (100%)
  - Tablet (768px)
  - Mobile (375px)
- Synchronized scrolling option
- Dynamic page switching dropdown
- Real-time variant comparison

### Preview Options
```bash
# Option 1: Direct browser (simplest)
cd .workflow/WFS-{session}/.design/prototypes
open index.html  # or double-click

# Option 2: Local server (recommended)
python -m http.server 8080      # Python
npx http-server -p 8080         # Node.js
php -S localhost:8080           # PHP
# Visit: http://localhost:8080
```

## 📦 What's Included

### New Commands (5)
- `/workflow:design:auto`
- `/workflow:design:style-extract`
- `/workflow:design:style-consolidate`
- `/workflow:design:ui-generate`
- `/workflow:design:design-update`

## 🔄 Workflow Integration

Design phase fits seamlessly between brainstorming and planning:

```
Brainstorming → UI Design → Planning → Execution
     ↓              ↓           ↓          ↓
synthesis-   design-tokens  tasks with  token-driven
specification   + style     design       implementation
                 guide      context
```

**Optional but recommended** for UI-heavy projects:
- User-facing applications
- Design system creation
- Brand-critical interfaces
- Accessibility compliance projects

  ↓
Phase 1: style-extract (automatic)
  ↓ [CHECKPOINT 1: User selects variants]
User: /workflow:design:style-consolidate --session WFS-xxx --variants "variant-1"
  ↓
Phase 3: ui-generate (automatic)
  ↓ [CHECKPOINT 2: User confirms prototypes]
User: /workflow:design:design-update --session WFS-xxx --selected-prototypes "dashboard-variant-1"
  ↓
Phase 5: batch-plan (optional, if --batch-plan flag)
```
