## [4.4.0] - 2025-10-11

### 🏗️ UI Design Workflow V3 - Layout/Style Separation Architecture

This release introduces a fundamental architectural refactoring that separates layout structure extraction from style token extraction, enabling the `generate` command to become a pure assembler.

#### Breaking Changes

**Command Renaming**:
```bash
# ❌ Old (v4.3.0 and earlier)
/workflow:ui-design:extract

# ✅ New (v4.4.0)
/workflow:ui-design:style-extract
```

**New Required Command**:
- **`/workflow:ui-design:layout-extract`**: Now mandatory for workflows using `generate`
- Layout templates must be generated before prototype assembly
- Both `imitate-auto` and `explore-auto` now include Phase 2.5 (layout extraction)

**Workflow Changes**:
```bash
# ❌ Old Flow (v4.3.0)
style-extract → consolidate → generate → update

# ✅ New Flow (v4.4.0)
style-extract → consolidate → layout-extract → generate (assembler) → update
```

#### Added

**New Command: `/workflow:ui-design:layout-extract`**:
- **Purpose**: Extract structural layout information separate from visual style
- **Features**:
  - Agent-powered structural analysis using `ui-design-agent`
  - Dual-mode operation: `imitate` (high-fidelity replication) / `explore` (multiple variants)
  - Device-aware layouts: desktop, mobile, tablet, responsive
  - Generates `layout-templates.json` with DOM structure and CSS layout rules
  - MCP-integrated layout pattern research (explore mode only)
  - Token-based CSS using `var()` placeholders for spacing and breakpoints
- **Output**: `layout-extraction/layout-templates.json` with:
  - DOM structure (semantic HTML5 with ARIA)
  - Component hierarchy (high-level layout regions)
  - CSS layout rules (Grid/Flexbox, no visual styling)
  - Device-specific structures and responsive breakpoints

**Enhanced Layout Extraction Architecture**:
```json
{
  "layout_templates": [
    {
      "target": "home",
      "variant_id": "layout-1",
      "device_type": "responsive",
      "design_philosophy": "3-column holy grail with fixed header",
      "dom_structure": { /* JSON object */ },
      "component_hierarchy": ["header", "main", "sidebar", "footer"],
      "css_layout_rules": "/* Grid/Flexbox only, uses var() */"
    }
  ]
}
```

**Device-Aware Layout Generation**:
- **Desktop**: 1920×1080px - Multi-column grids, spacious layouts
- **Mobile**: 375×812px - Single column, stacked sections, touch targets ≥44px
- **Tablet**: 768×1024px - Hybrid layouts, flexible columns
- **Responsive**: Mobile-first breakpoint-driven adaptive layouts

**MCP Integration (Explore Mode)**:
- `mcp__exa__web_search_exa` for layout pattern inspiration
- Pattern research: `{target} layout patterns {device_type}`
- Inspiration files: `layout-extraction/_inspirations/{target}-layout-ideas.txt`

#### Changed

**`/workflow:ui-design:style-extract` (Renamed from `extract`)**:
- **File Renamed**: `extract.md` → `style-extract.md`
- **Scope Clarified**: Focus exclusively on visual style (colors, typography, spacing)
- **Documentation Updated**: Added note about layout extraction separation
- **No Functionality Change**: All style extraction features preserved
- **Output**: Still generates `style-cards.json` with `proposed_tokens`

**`/workflow:ui-design:generate` (Refactored to Pure Assembler)**:
- **Before (v4.3.0)**: Layout design + style application agent
  - Agent made layout decisions during generation
  - Mixed structural and visual responsibilities
  - CSS contained both layout and style rules

- **After (v4.4.0)**: Pure assembly only
  - **Reads**: `layout-templates.json` + `design-tokens.json`
  - **Action**: Combines pre-extracted components:
    1. Build HTML from `dom_structure`
    2. Apply `css_layout_rules` (structure)
    3. Link design tokens CSS (visual style)
    4. Inject placeholder content
  - **No Design Logic**: All layout and style decisions pre-made
  - **Agent Prompt Updated**: Removed layout design instructions

**Agent Instructions Simplification** (`generate.md`):
```javascript
// ❌ Old (v4.3.0): Agent designs layout + applies style
Agent: "Design page layout based on requirements, then apply design tokens"

// ✅ New (v4.4.0): Agent only assembles
Agent: "
  [LAYOUT_STYLE_ASSEMBLY]
  Read layout-templates.json → Extract dom_structure, css_layout_rules
  Read design-tokens.json → Extract ALL token values
  Build HTML from dom_structure
  Build CSS from css_layout_rules + token values
  Write files IMMEDIATELY
"
```

**Workflow Commands Updated**:
- **`/workflow:ui-design:imitate-auto`**:
  - Added Phase 2.5: Layout Extraction (imitate mode, single variant)
  - Generates `layout-templates.json` before Phase 4 (UI Assembly)
  - Uses `--mode imitate` for high-fidelity layout replication

- **`/workflow:ui-design:explore-auto`**:
  - Added Phase 2.5: Layout Extraction (explore mode, multiple variants)
  - Generates `{targets × layout_variants}` layout templates
  - Uses `--mode explore` for structural variety
  - MCP-powered layout pattern research

**Output Structure Changes**:
```
{base_path}/
├── style-extraction/         # Visual tokens (unchanged)
│   └── style-cards.json
├── layout-extraction/        # NEW: Structural templates
│   ├── layout-templates.json
│   ├── layout-space-analysis.json (explore mode)
│   └── _inspirations/ (explore mode)
├── style-consolidation/      # Final design tokens (unchanged)
│   └── style-1/
│       └── design-tokens.json
└── prototypes/               # Assembled output (unchanged)
    └── {target}-style-{s}-layout-{l}.html
```

#### Improved

**Separation of Concerns**:
- 🎨 **Style (style-extract)**: Colors, typography, spacing → design-tokens.json
- 🏗️ **Layout (layout-extract)**: DOM structure, CSS layout → layout-templates.json
- 📦 **Assembly (generate)**: Combine structure + style → final prototypes
- ✅ **Result**: Each phase has single, clear responsibility

**Quality Improvements**:
- 🎯 **Better Layout Variety**: Explore mode generates structurally distinct layouts
- 🔄 **Reusability**: Layout templates can be combined with different styles
- 📊 **Clarity**: All structural decisions in layout-templates.json
- 🧪 **Testability**: Layout structure and visual style tested independently

**Performance Benefits**:
- ⚡ **Faster Generation**: Assembly is simpler than design + application
- 🔄 **Better Caching**: Layout templates reused across style variants
- 📉 **Reduced Complexity**: Generate agent has single responsibility

#### Technical Details

**Phase Flow Comparison**:

**Old Flow (v4.3.0)**:
```
Phase 1: style-extract → style-cards.json
Phase 2: consolidate → design-tokens.json
Phase 3: generate (design+apply) → prototypes
Phase 4: update
```

**New Flow (v4.4.0)**:
```
Phase 1: style-extract → style-cards.json
Phase 2: consolidate → design-tokens.json
Phase 2.5: layout-extract → layout-templates.json  [NEW]
Phase 3: generate (pure assembly) → prototypes
Phase 4: update
```

**Agent Task Changes**:

**Before (Mixed Responsibility)**:
```javascript
Agent Task: "
  Design page layout for {target}
  Apply design tokens from design-tokens.json
  Generate HTML + CSS
"
// Problems:
// - Layout decisions made during generation
// - Style application mixed with structure
// - Agent has dual responsibility
```

**After (Pure Assembly)**:
```javascript
Agent Task: "
  [LAYOUT_STYLE_ASSEMBLY]
  INPUT 1: layout-templates.json → dom_structure, css_layout_rules
  INPUT 2: design-tokens.json → token values

  ASSEMBLY:
  1. Build HTML from dom_structure
  2. Build CSS from css_layout_rules (replace var())
  3. Add visual styling using token values
  4. Write files IMMEDIATELY

  RULES:
  ✅ Pure assembly only
  ❌ NO layout design decisions
  ❌ NO style design decisions
"
```

**Layout Template Structure**:
```json
{
  "target": "home",
  "variant_id": "layout-1",
  "device_type": "responsive",
  "design_philosophy": "F-pattern with sticky nav",
  "dom_structure": {
    "tag": "body",
    "children": [
      {"tag": "header", "attributes": {"class": "layout-header"}},
      {"tag": "main", "attributes": {"class": "layout-main"}},
      {"tag": "footer", "attributes": {"class": "layout-footer"}}
    ]
  },
  "component_hierarchy": ["header", "main", "footer"],
  "css_layout_rules": ".layout-main { display: grid; grid-template-columns: 1fr 3fr; gap: var(--spacing-6); }"
}
```

**Token-Based CSS Pattern**:
```css
/* Layout rules use var() for spacing/breakpoints */
.layout-wrapper {
  display: grid;
  gap: var(--spacing-4);
  padding: var(--spacing-8);
}

@media (max-width: var(--breakpoint-md)) {
  .layout-wrapper {
    grid-template-columns: 1fr;
  }
}
```

#### Migration Guide

**For Existing Workflows**:
1. **Update Command Names**:
   ```bash
   # Old: /workflow:ui-design:extract
   # New: /workflow:ui-design:style-extract
   ```

2. **Add Layout Extraction Step**:
   ```bash
   # After consolidate, before generate:
   /workflow:ui-design:layout-extract --session WFS-xxx --targets "dashboard,settings" --mode explore --variants 3
   ```

3. **Update Orchestrator Workflows**:
   - `imitate-auto`: Automatically includes Phase 2.5
   - `explore-auto`: Automatically includes Phase 2.5
   - Manual workflows: Add `layout-extract` call

**Backward Compatibility**:
- ✅ Old `extract` command files archived (not deleted)

## [4.3.0] - 2025-10-10

### 🎨 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

**Developer Experience**:
- 🚀 **Faster Execution**: Removed 2 intermediate processing steps
- 📁 **Simpler Output**: No more tokens.css files to manage
- 🔍 **Easier Inspection**: All styling visible in prototype CSS files

- **Combined**: 196 lines of documentation optimized
- **Zero functionality loss**: All features, workflows, and technical details preserved

## [4.2.0] - 2025-10-09

### 🎯 Multi-Page Support Enhancement

Based on Gemini's analysis of the UI Design Workflow, this version implements four key optimizations to improve the multi-page design experience.

#### Added

- **Cross-Page Consistency Validation**: New `Phase 3.5` in `generate` command automatically validates design consistency (shared components, tokens, accessibility) across multiple pages
- **Side-by-Side Prototype Comparison**: `compare.html` preview tool now includes "Side-by-Side" tab to compare any two prototypes with intelligent consistency hints
- **Batch Prototype Selection**: `compare.html` features "By Style" and "By Layout" buttons for quick bulk prototype selection

#### Changed

- **Enhanced Page Inference**: `auto` command's page detection uses multiple regex patterns with interactive user confirmation
- **Improved Export**: Selection export from `compare.html` is now more structured with detailed metadata

## [4.1.1] - 2025-10-09

### 🔧 Symlink Fix & Agent Optimization

#### Fixed

- **Windows Symbolic Link Creation**: Corrected `auto.md` workflow to use `mklink /D` on Windows, preventing duplicate directories instead of symlinks

#### Changed

- **Agent Allocation Strategy**: `generate.md` now allocates tasks by layout (layout-based) instead of style, improving performance and consistency for high variant counts by having one agent handle one layout strategy across multiple styles

## [4.1.0] - 2025-10-09

### 🔄 Matrix-Only UI Design Workflow

#### Changed

- **Matrix Mode by Default**: UI Design workflow now exclusively uses `style × layout` matrix mode with `--style-variants` and `--layout-variants` as standard parameters
- **Path Standardization**: Standalone design sessions saved to `.workflow/.scratchpad/` adhering to project architecture
- **Simplified Orchestration**: `auto.md` command simplified to use single `SlashCommand` for generation phase, removing complex loop logic

#### Removed

- **Deprecated Parameters**: Removed `--variants` and `--creative-variants` in favor of explicit `--style-variants` and `--layout-variants`
- **Standard/Creative Modes**: Distinction between these modes removed

---

## [4.0.2] - 2025-10-09

### 🔄 UI Design Workflow - Complete Refactoring

- **After**: Unified agent-only execution
  - standard: Single Task(conceptual-planning-agent) for consistent variants
  - creative: Parallel Task(conceptual-planning-agent) for diverse layouts
  - Only `--variants` or `--creative-variants` determines mode
- **Removed**: `--tool` parameter, conventional mode

**design-update (`/workflow:ui-design:update`)**:
- **Before**: References `style-philosophy.md`
- **After**: Extracts philosophy from `style-guide.md`
- **Changed**: Adapted to new 4-file output structure from consolidate phase

**auto (`/workflow:ui-design:auto`)**:
- **Before**: Passed `--tool` flags to sub-commands
- **After**: No tool parameters, pure orchestration

## [4.0.1] - 2025-10-07

### 🎯 Intelligent Page Inference

**IMPROVEMENT**: `--pages` parameter is now **optional** with smart inference from prompt or session context.

**Changes**:
- `--pages` parameter: Now optional, intelligently inferred from:
  1. Explicit `--pages` if provided
  2. `--prompt` text analysis (e.g., "blog with home, article pages" → ["home", "article"])
  3. `--session` synthesis-specification.md extraction
  4. Default: ["home"]

**New Examples**:
```bash
# Simplest - pages inferred from prompt
/workflow:ui-design:auto --prompt "Modern blog with home, article and author pages"

# Explicit override if needed
/workflow:ui-design:auto --prompt "SaaS app" --pages "dashboard,settings,billing"
```

**Commands Updated**:
- `/workflow:ui-design:auto`: All parameters now optional
- `/workflow:ui-design:ui-generate`: `--pages` optional with smart inference

## [4.0.0] - 2025-10-07

### 🚀 UI Design Workflow V2 - Agent Mode & Flexible Inputs

**BREAKING CHANGES**: Complete redesign of UI design workflow with mandatory new parameter structure. All old command formats are deprecated.

This major release introduces agent-driven creative exploration, unified variant control, dual-mode support (standalone/integrated), and flexible input sources (images + text prompts).

#### Breaking Changes

**Required Migration**:
- **Old format no longer supported**: Commands using old parameter structure will fail
- **All parameters now optional**: Smart defaults and inference for all parameters
- **`--session`**: Optional, omitting enables standalone mode
- **`--images`**: Optional with default `design-refs/*`
- **`--pages`**: Optional, inferred from prompt or session (as of v4.0.1)
- **Removed `--style-overrides`**: Use `--prompt` instead

**Migration Guide**:
```bash
# ❌ Old (v3.5.0 and earlier) - NO LONGER WORKS
/workflow:ui-design:style-extract --session WFS-auth --images "design-refs/*.png"
/workflow:ui-design:ui-generate --session WFS-auth --pages "login,register"

# ✅ New (v4.0.1) - All parameters optional
/workflow:ui-design:style-extract --images "design-refs/*.png" --variants 3
/workflow:ui-design:ui-generate --variants 2

# ✅ Simplest form (pages inferred from prompt)
/workflow:ui-design:auto --prompt "Modern blog with home, article and author pages"

# ✅ With agent mode and explicit pages
/workflow:ui-design:auto --prompt "Modern SaaS" --pages "dashboard,settings" --variants 3 --use-agent
```

**Deprecated Commands**:
- Old `style-extract` format without `--variants`
- Old `ui-generate` format without `--use-agent` support
- `--style-overrides` parameter (replaced by `--prompt`)

#### Added

**Unified Variant Control**:
- **`--variants <count>`**: Single parameter controls both style cards AND UI prototypes generation
  - Default: 3 | Range: 1-5
  - Data flow: `auto.md` → `style-extract` → `ui-generate`
  - Example: `--variants 3` generates 3 style cards and 3 UI variants per page

**Agent Creative Exploration Mode** (`--use-agent`):
- **style-extract**: Parallel generation of distinctly different design directions
  - Conventional mode: Subtle variations within same core style
  - Agent mode: Dramatically different aesthetics (e.g., "Modern Minimalist" vs "Brutalist Tech" vs "Organic Warmth")
  - Uses `conceptual-planning-agent` for creative exploration
- **ui-generate**: Diverse layout strategies exploration
  - Conventional mode: Minor layout differences
  - Agent mode: Structural variations (F-Pattern, Asymmetric Grid, Card-Based Modular)
  - Parallel execution for efficiency

**Dual Mode Support**:
- **Integrated Mode** (with `--session`): Works within existing workflow session
  - Location: `.workflow/WFS-{session}/`
  - Reads from `.brainstorming/` artifacts
  - Phase 4 (design-update) updates synthesis-specification.md
- **Standalone Mode** (without `--session`): Independent quick prototyping
  - Auto-creates: `design-session-YYYYMMDD-HHMMSS/`
  - No dependency on brainstorming phase
  - Phase 4 (design-update) is skipped
  - Outputs final summary instead

**Dual Input Source Support**:
- **`--images`**: Reference image paths (optional, default: `design-refs/*`)
- **`--prompt`**: Text description of design style (NEW)
- **Hybrid Mode**: Both combined - text guides image analysis
- Input modes:
  - Pure image: Existing triple vision analysis
  - Pure text: Claude keywords → Gemini philosophy → Codex tokens
  - Hybrid: Text as context for visual analysis

#### Changed

**New Command Interface** (v4.0.1):
- **`/workflow:ui-design:auto`**:
  - All parameters optional with smart defaults
  - `--prompt <desc>`: Design description (infers pages automatically)
  - `--images <glob>`: Reference images (default: `design-refs/*`)
  - `--pages <list>`: Explicit page override (auto-inferred if omitted)
  - `--session <id>`, `--variants <count>`, `--use-agent`, `--batch-plan`
  - Examples:
    - Minimal: `/workflow:ui-design:auto --prompt "Modern blog with home and article pages"`
    - Agent Mode: `/workflow:ui-design:auto --prompt "SaaS dashboard and settings" --variants 3 --use-agent`
    - Hybrid: `/workflow:ui-design:auto --images "refs/*.png" --prompt "E-commerce: home, product, cart"`

- **`/workflow:ui-design:style-extract`**:
  - At least one of `--images` or `--prompt` recommended
  - All other parameters optional
  - Agent mode: Parallel generation of diverse design directions

- **`/workflow:ui-design:ui-generate`**:
  - All parameters optional (pages inferred from session or defaults to ["home"])
  - `--pages <list>`: Optional explicit page list
  - Agent mode: Parallel layout exploration (F-Pattern, Grid, Asymmetric)

#### Usage Examples

**Standalone Quick Prototyping**:
```bash
# Pure text with page inference (simplest)
/workflow:ui-design:auto --prompt "Modern minimalist blog with home, article and author pages, dark theme" --use-agent

# Pure image with inferred pages
/workflow:ui-design:auto --images "refs/*.png" --variants 2

# Hybrid input with explicit page override
/workflow:ui-design:auto --images "current-app.png" --prompt "Modernize to Linear.app style" --pages "tasks,settings" --use-agent
```

**Integrated Workflow Enhancement**:
```bash
# Within existing workflow (pages inferred from synthesis)
/workflow:ui-design:auto --session WFS-app-refresh --images "refs/*.png" --variants 3 --use-agent
```

#### Technical Details

**Agent Mode Architecture**:
- Uses `conceptual-planning-agent` for both style-extract and ui-generate phases
- Parallel task execution: N variants × M pages run concurrently
- Theme diversity strategies:
  - style-extract: Creative theme generation (Minimalist, Brutalist, Organic)
  - ui-generate: Layout strategy assignment (F-Pattern, Grid, Asymmetric)
- Quality assurance: All variants maintain strict token adherence and WCAG AA compliance

**Mode Detection Logic**:
```bash
# Session mode
IF --session provided: mode = "integrated"
ELSE: mode = "standalone", auto-create design-session-YYYYMMDD-HHMMSS/

# Execution mode
IF --use-agent: mode = "agent" (creative exploration)
ELSE: mode = "conventional" (triple vision)

# Input mode
IF --images AND --prompt: mode = "hybrid"
ELSE IF --images: mode = "image"
ELSE IF --prompt: mode = "text"
```

#### Upgrade Benefits

**Simplified Workflow**:
- Fewer required parameters (only `--pages` mandatory)
- Smart defaults reduce boilerplate
- Standalone mode for quick prototyping without workflow setup

**Enhanced Capabilities**:
- Agent-driven creative exploration produces diverse designs
- Parallel execution improves performance
- Text prompts enable design without reference images

**Quality Improvements**:
- All variants maintain strict token adherence
- WCAG AA compliance validated automatically
- Better separation of concerns (style vs layout)

#### Changed

**CLI Command Documentation Refactoring**:
- Refactored 7 CLI command documentation files to eliminate redundancy
- Removed **681 total lines** of duplicate content across all files
- Established implicit reference pattern to `intelligent-tools-strategy.md` (loaded in memory)
- Preserved all unique command-specific content and capabilities

**Specific File Reductions**:
- `analyze.md`: 117→61 lines (48% reduction)
- `chat.md`: 118→62 lines (47% reduction)
- `execute.md`: 180→100 lines (44% reduction)
- `codex-execute.md`: 481→473 lines (2% - preserved unique workflow content)
- `mode/bug-index.md`: 144→75 lines (48% reduction)
- `mode/code-analysis.md`: 188→76 lines (60% reduction)
- `mode/plan.md`: 100→76 lines (24% reduction)

**Removed Duplicate Sections**:
- Universal Command Template (now only in `intelligent-tools-strategy.md`)
- File Pattern Reference (centralized in strategy guide)
- Complex Pattern Discovery (centralized in strategy guide)
- MODE Field Definition (centralized in strategy guide)
- Enhancement Integration details (referenced implicitly)
- Session Persistence details (referenced implicitly)

**Preserved Unique Content**:
- Command-specific purpose and parameters
- Unique execution flows and capabilities
- Specialized features (YOLO permissions, task decomposition, resume patterns)
- Command-specific examples and workflows
- File pattern auto-detection logic for analyze command
- Group-based execution workflow for codex-execute command

#### Added

**Documentation Enhancement** (prior to refactoring):

  - `feature|bugfix|refactor|test-gen` → `@code-developer`
  - `test-fix` → `@test-fix-agent`
  - `review` → `@general-purpose` (optional)

**Workflow Changes**:
```
Old: code-developer → test-agent → code-review-agent
New: code-developer (code+tests) → test-fix-agent (execute+fix) → ✅ approved
```

#### Removed

- `@code-review-agent` - Testing serves as quality gate
