### 🎨 UI Design Workflow V2 - Self-Contained CSS Architecture
|
||||
|
||||
This release introduces a major architectural improvement to the UI Design Workflow, removing the placeholder mechanism and enabling agents to generate fully self-contained CSS files directly from design tokens.
|
||||
|
||||
#### Changed
|
||||
|
||||
**UI Design Workflow V2 Commands**:
|
||||
- **`/workflow:ui-design:generate-v2`**: Enhanced prototype generation with self-contained CSS
|
||||
- Agents now read `design-tokens.json` and generate independent CSS files
|
||||
- CSS contains direct token values (e.g., `#3b82f6`) instead of `var()` references
|
||||
- HTML files reference CSS directly: `<link rel="stylesheet" href="page-style-1-layout-2.css">`
|
||||
- No more placeholder mechanism or post-processing steps
|
||||
|
||||
- **`/workflow:ui-design:explore-auto-v2`**: Updated to use new generation architecture
|
||||
- Automatic coordination with `generate-v2` command
|
||||
- Streamlined workflow without placeholder replacement
|
||||
|
||||
**Removed Dependencies**:
|
||||
- ❌ **No more `tokens.css`**: Eliminated intermediate CSS variable files
|
||||
- ❌ **No more Phase 1.6**: Removed token-to-CSS conversion step
|
||||
- ❌ **No more placeholder replacement**: Scripts no longer process `{{STYLE_CSS}}` placeholders
|
||||
|
||||
**Agent Instructions Enhanced**:
|
||||
- Agents receive `design-tokens.json` as primary design system reference
|
||||
- Direct CSS generation instructions with token value extraction guidance
|
||||
- Better adaptation to `design_attributes` (density, visual_weight, formality, etc.)
|
||||
- Example instruction: "Use color values for backgrounds, typography values for fonts"
|
||||
|
||||
**Script Simplification** (`ui-generate-preview-v2.sh`):
|
||||
- Removed placeholder replacement logic (32 lines removed)
|
||||
- Focus solely on preview file generation (compare.html, index.html, PREVIEW.md)
|
||||
- Cleaner, more focused responsibility
|
||||
|
||||
#### Improved
|
||||
|
||||
**Style Differentiation**:
|
||||
- 🎨 **Better Style Diversity**: Agents can now freely adapt token values based on design philosophy
|
||||
- 🎯 **Stronger Visual Identity**: Each style variant can use different color spaces, typography scales
|
||||
- 💡 **Design-Aware Selection**: Agents intelligently select tokens matching design_attributes
|
||||
|
||||
**Workflow Simplicity**:
|
||||
- 📉 **Reduced Complexity**: 346 lines of code removed (net reduction)
|
||||
- ⚡ **Fewer Steps**: Eliminated intermediate conversion and replacement phases
|
||||
- 🔧 **Easier Debugging**: All styling visible directly in generated CSS files
|
||||
- 📝 **Clearer Agent Tasks**: Agents have single, focused responsibility
|
||||
|
||||
**CSS Generation Quality**:
|
||||
- 🎨 **Fully Embodies Design**: CSS directly reflects design token values
|
||||
- 🔄 **No External Dependencies**: Each CSS file is completely self-contained
|
||||
- 📊 **Better Adaptation**: Agents can adjust values based on layout context
|
||||
- 🎯 **Style-Specific Implementation**: Same layout + different style = truly different CSS
|
||||
|
||||
#### Technical Details
|
||||
|
||||
**Before (v4.2.x)**:
|
||||
```html
|
||||
<!-- Agent generates HTML with placeholders -->
|
||||
<link rel="stylesheet" href="{{TOKEN_CSS}}">
|
||||
<link rel="stylesheet" href="{{STRUCTURAL_CSS}}">
|
||||
|
||||
<!-- Phase 1.6: Convert design-tokens.json → tokens.css -->
|
||||
<!-- Phase 3a: Replace placeholders with actual paths -->
|
||||
```
|
||||
|
||||
**After (v4.3.0)**:
|
||||
```html
|
||||
<!-- Agent generates HTML with direct reference -->
|
||||
<link rel="stylesheet" href="dashboard-style-1-layout-2.css">
|
||||
|
||||
<!-- CSS contains direct values from design-tokens.json -->
|
||||
.button { background: #3b82f6; font-size: 16px; }
|
||||
```
|
||||
|
||||
**Workflow Comparison**:
|
||||
```
|
||||
Old Flow:
|
||||
Phase 1.5: Inspiration → Phase 1.6: Token Conversion → Phase 2: Agent Gen →
|
||||
Phase 3a: Replace Placeholders → Phase 3b: Preview
|
||||
|
||||
New Flow:
|
||||
Phase 1.5: Inspiration → Phase 2: Agent Gen (reads tokens.json directly) →
|
||||
Phase 3: Preview
|
||||
```
|
||||
|
||||
#### Benefits
|
||||

|
||||
- 📁 **Simpler Output**: No more tokens.css files to manage

|
||||
- 🎯 **Clearer Intent**: Direct mapping from design tokens to CSS
|
||||
|
||||
**Design Quality**:
|
||||
- 🎨 **Richer Style Variations**: Agents can adapt token usage creatively
|
||||
- 💪 **Stronger Differentiation**: Each style truly looks different
|
||||

||||

|
||||
|
||||

|
||||
|
||||
#### Migration Notes
|
||||
|
||||
**No Breaking Changes** for users:
|
||||
- ✅ V2 commands are separate from V1 (`generate-v2` vs `generate`)
|
||||
- ✅ Existing workflows continue to work unchanged
|
||||
- ✅ New commands are opt-in
|
||||
|
||||
**For New Projects**:
|
||||
- Use `/workflow:ui-design:generate-v2` for better style differentiation
|
||||
- Use `/workflow:ui-design:explore-auto-v2` for automatic workflow
|
||||
|
||||
**Design Token Changes**:
|
||||
- `design-tokens.json` structure unchanged
|
||||
- `tokens.css` files no longer generated (V2 commands only)
|
||||
- Style guides (`style-guide.md`) unchanged
