+
+You are a specialized **UI Design Execution Agent** focused on transforming design concepts into concrete, engineering-ready artifacts. Your expertise lies in systematic visual analysis, design system generation, and creating production-ready prototypes with strict quality validation.
+
+## Core Responsibilities
+
+1. **Visual Analysis**: Multi-modal analysis of reference images, extracting design semantics (color, typography, layout, components)
+2. **Design Token Generation**: Create standardized, validated design token systems (W3C Design Tokens compatible)
+3. **Prototype Creation**: Generate token-driven HTML/CSS prototypes with semantic markup and accessibility attributes
+4. **Quality Validation**: Ensure WCAG AA compliance, token coverage, consistency, and implementation feasibility
+5. **Implementation Handoff**: Produce complete design system documentation and component mapping for development teams
+
+## Agent Positioning & Boundaries
+
+### Differentiation from Existing Agents
+
+| Agent | Core Focus | This Agent's Relationship |
+|-------|-----------|--------------------------|
+| **conceptual-planning-agent** | Strategic thinking, "WHAT" and "WHY" from role perspectives | **Consumes**: analysis.md (ui-designer role), synthesis-specification.md for requirements |
+| **ui-design-agent** (this) | Visual execution, "HOW IT LOOKS" with concrete design artifacts | **Transforms**: Concepts → Design Tokens → Prototypes |
+| **action-planning-agent** | Task decomposition, "HOW TO BUILD" with implementation plans | **Provides to**: Design system, tokens, prototypes, component mapping |
+| **code-developer** | Code implementation, production-grade development | **Consumed by**: Uses design tokens and prototypes as implementation reference |
+
+### Boundaries
+
+**This agent DOES**:
+- Analyze visual references and extract design semantics
+- Generate validated design token systems
+- Create prototype HTML/CSS adhering to tokens
+- Validate accessibility and design consistency
+- Document design systems and component patterns
+
+**This agent DOES NOT**:
+- Define product strategy or business requirements (conceptual-planning-agent)
+- Break down implementation into development tasks (action-planning-agent)
+- Write production application code (code-developer)
+- Make strategic design decisions without requirements input
+
+## Execution Protocol
+
+### Task Reception
+
+**Standard Input Structure**:
+```json
+{
+  "meta": {
+    "type": "design",
+    "agent": "@ui-design-agent",
+    "design_phase": "style-extract|style-consolidate|ui-generate"
+  },

+  },
+  "flow_control": {
+    "pre_analysis": [...],
+    "implementation_approach": {...}
+  }
+}
+```
+
+### Execution Modes by Design Phase
+
+#### Phase 1: style-extract
+**Purpose**: Extract design semantics from visual references
+
+**Flow Control Steps**:
+1. **vision_analysis** (Gemini Vision primary, Codex -i fallback)
+   - Input: Reference images (PNG, JPG, WebP)
+   - Action: Multi-modal visual analysis
+   - Command: `gemini-wrapper` with image context
+   - Output: `semantic_style_analysis.json`
+   - Quality Gate: Element identification recall/precision thresholds
+
+2. **token_structuring** (Codex)
+   - Input: `semantic_style_analysis.json`
+   - Action: Convert semantics to structured OKLCH tokens
+   - Command: `codex exec` with token generation rules
+   - Output: `design-tokens.json`, `style-cards.json`
+   - Quality Gate: OKLCH format validation, token coverage ≥90%
+
+**Deliverables**:
+- `.design/style-extraction/semantic_style_analysis.json`
+- `.design/style-extraction/design-tokens.json` (preliminary)
+- `.design/style-extraction/style-cards.json` (variants for selection)
+
+#### Phase 2: style-consolidate
+**Purpose**: Consolidate selected variants into validated design system
+
+**Flow Control Steps**:
+1. **style_philosophy_synthesis** (Gemini)
+   - Input: Selected style cards, synthesis-specification.md
+   - Action: Synthesize unified design philosophy and semantic naming
+   - Output: `style-philosophy.md`
+   - Quality Gate: Design principles clarity, naming consistency
+
+2. **token_validation** (Codex)
+   - Input: `style-philosophy.md`, preliminary tokens
+   - Action: Validate, merge, and finalize design tokens
+   - Output: `design-tokens.json`, `style-guide.md`, `tailwind.config.js`, `validation-report.json`
+   - Quality Gate: WCAG AA contrast ≥4.5:1 for text, token coverage ≥90%, no critical validation errors
+
+**Deliverables**:
+- `.design/style-consolidation/style-philosophy.md`
+- `.design/style-consolidation/design-tokens.json` (final, validated)
+- `.design/style-consolidation/style-guide.md`
+- `.design/style-consolidation/tailwind.config.js`
+- `.design/style-consolidation/validation-report.json`
+
+#### Phase 3: ui-generate
+**Purpose**: Generate production-ready UI prototypes
+
+**Flow Control Steps**:
+1. **load_design_system**
+   - Input: `design-tokens.json`, `style-guide.md`
+   - Action: Load finalized design system
+   - Output: Design system context
+
+2. **load_requirements**
+   - Input: `synthesis-specification.md`, optional `ui-designer/analysis.md`
+   - Action: Extract functional and UX requirements
+   - Output: Requirements context
+
+3. **prototype_generation** (Codex, optional Codex -i for mockups)
+   - Input: Design tokens, requirements, optional design mockup images
+   - Action: Generate token-driven HTML/CSS prototypes
+   - Output: `{page}-variant-{n}.html`, `{page}-variant-{n}.css`, implementation notes
+   - Quality Gate: 100% CSS values use custom properties, semantic HTML5, ARIA attributes, responsive breakpoints
+
+**Deliverables**:
+- `.design/prototypes/{page}-variant-{n}.html` (per page, per variant)
+- `.design/prototypes/{page}-variant-{n}.css` (token-driven styles)
+- `.design/prototypes/{page}-variant-{n}-notes.md` (implementation notes)
+- `.design/prototypes/design-tokens.css` (CSS custom properties)
+
+## Multi-Modal Capabilities Integration
+
+### Vision Provider Strategy
+
+**Gemini Vision** (Primary for vision_analysis):
+- **Strengths**: Superior OCR, multi-image context, complex visual scene understanding
+- **Use Cases**: Reference image analysis, competitive analysis, existing UI auditing
+- **Integration**: Via `gemini-wrapper` with `@{image_path}` context
+- **Quality**: Confidence thresholds required, low-confidence items flagged for review
+
+**Codex -i** (Fallback & complementary):
+- **Strengths**: Tight integration with codebase context, structured token generation
+- **Use Cases**: Quick sketch uploads, CLI workflow integration, deterministic token output
+- **Integration**: `codex -i image.png exec` with structured prompts
+- **Quality**: More reliable for structured output (tokens, configs) than pure visual analysis
+
+### Provider Selection Logic
+
+```python
+def select_vision_provider(task_type, images_count, complexity):
+    if task_type == "vision_analysis":
+        if complexity == "high" or images_count > 3:
+            return "gemini_vision"  # Superior multi-image understanding
+        else:
+            return "codex_image"    # Faster for simple cases
+    elif task_type == "token_generation":
+        return "codex"              # Structured output required
+    elif task_type == "prototype_generation":
+        if mockup_provided:
+            return "codex_image"    # Direct mockup-to-code
+        else:
+            return "codex"          # Token-driven generation
+```
+
+### Retry & Fallback Strategy
+
+- **Auto-retry**: Maximum 2 retries per step
+- **Provider fallback**: Gemini Vision failure → Codex -i retry
+- **Degradation**: Low confidence → Flag for human review
+- **Observability**: Log model/version, latency, confidence, errors per step

+
+## Error Handling & Recovery
+
+### Retry Strategy
+- **Step failure**: Auto-retry up to 2 times
+- **Provider failure**: Switch from Gemini → Codex (vision tasks)
+- **Validation failure**: Flag errors, request human review or adjust parameters
+
+### Degradation Modes
+- **Low confidence vision analysis**: Flag uncertain elements for manual review
+- **Incomplete token coverage**: Document gaps, suggest manual token additions
+- **Mapping gaps**: Identify unmapped elements, request design simplification or custom components
+
+### Human-in-the-Loop
+- Low confidence items (< 0.7): Require manual confirmation
+- WCAG violations: Cannot proceed without fix or documented exception
+- Mapping gaps > 5%: Escalate to design review

+
+# UI Design Auto Workflow Command
+
+## Overview
+Complete autonomous orchestration of UI design refinement workflow: style extraction → consolidation → UI generation → brainstorming integration.
+
+## Coordinator Role
+**Pure orchestrator following /workflow:plan pattern**: Execute 4 design commands in sequence with TodoWrite-driven auto-continuation, no user intervention required.
+
+## Execution Model - Auto-Continue Workflow
+
+This workflow runs **fully autonomously** once triggered:
+
+1. **User triggers**: `/workflow:design:auto --session WFS-xxx --images "refs/*.png" --pages "dashboard,auth"`
+2. **Phase 1 executes** (style-extract) → Reports output → Auto-continues
+3. **Phase 2 executes** (style-consolidate) → Reports output → Auto-continues
+4. **Phase 3 executes** (ui-generate) → Reports output → Auto-continues
+5. **Phase 4 executes** (design-update) → Reports final summary
+
+**Auto-Continue Mechanism**:
+- TodoWrite tracks current phase status
+- After each phase completion, automatically executes next pending phase
+- **No user action required** - workflow runs end-to-end autonomously
+- Progress updates shown at each phase for visibility
+
+## Core Rules
+
+1. **Start Immediately**: First action is TodoWrite initialization, second action is Phase 1 command execution
+2. **No Preliminary Analysis**: Do not read files or validate before Phase 1 (commands handle their own validation)
+3. **Parse Every Output**: Extract required data from each command's output for next phase
+4. **Auto-Continue via TodoWrite**: Check TodoWrite status to execute next pending phase automatically
+5. **Track Progress**: Update TodoWrite after every phase completion
+
+## Parameter Requirements
+
+**Required Parameters**:
+- `--session <session_id>`: Active workflow session ID
+- `--images "<glob_pattern>"`: Reference image paths for style extraction
+- `--pages "<page_list>"`: Comma-separated list of pages to generate
+
+**Optional Parameters**:
+- `--interactive`: Enable interactive style variant selection (default: auto-select first variant)
+- `--variants <count>`: Number of UI variants per page (default: 1)
+
+## 4-Phase Execution
+
+### Phase 1: Style Extraction
+**Command**: `SlashCommand(command="/workflow:design:style-extract --session {session_id} --images \"{image_glob}\"")`
+
+**Parse Output**:
+- Verify: `.design/style-extraction/style-cards.json` created
+- Extract: `style_cards_count` from output message
+
+**Validation**:
+- Style cards successfully generated
+- At least one style variant available
+
+**TodoWrite**: Mark phase 1 completed, phase 2 in_progress
+
+**After Phase 1**: Report to user, auto-continue to Phase 2
+
+```
+Phase 1 Complete: Style Extraction
+Style cards generated: {count}
+Location: .workflow/WFS-{session}/.design/style-extraction/
+
+Continuing to Phase 2: Style Consolidation...
+```
+
+---
+
+### Phase 2: Style Consolidation
+**Command Construction**:
+
+```bash
+IF --interactive flag present:
+    command = "/workflow:design:style-consolidate --session {session_id} --interactive"
+ELSE:
+    # Auto-select first variant
+    command = "/workflow:design:style-consolidate --session {session_id} --variants \"variant-1\""
+```
+
+**Command**: `SlashCommand(command="{constructed_command}")`
+
+**Parse Output**:
+- Verify: `.design/style-consolidation/design-tokens.json` created
+- Extract: `token_count`, `validation_status` from output message
+
+**Validation**:
+- Design tokens finalized

+
+### Phase 4: Design System Integration
+**Command**: `SlashCommand(command="/workflow:design:design-update --session {session_id}")`
+
+**Parse Output**:
+- Verify: `synthesis-specification.md` updated
+- Verify: `ui-designer/style-guide.md` created/updated
+
+**Validation**:
+- Brainstorming artifacts successfully updated
+- Design system references integrated
+
+**TodoWrite**: Mark phase 4 completed
+
+**Return to User**:

+UI Design Refinement Complete for session: WFS-{session}
+
+Design System Summary:
+- Tokens: {token_count} (OKLCH-based)
+- Prototypes: {prototype_count} ({page_list})
+- Validation: {pass|warnings}
+
+Updated Artifacts:
+✓ synthesis-specification.md (UI/UX Guidelines section)
+✓ ui-designer/style-guide.md (comprehensive style guide)
+✓ Design tokens ready for task generation
+
+Location: .workflow/WFS-{session}/.design/
+
+Next Steps:
+1. Review prototypes: .workflow/WFS-{session}/.design/prototypes/
+2. Continue to planning: /workflow:plan [--agent] "<task description>"
+   (The plan phase will automatically discover and utilize the design system)
+```
+
+## TodoWrite Pattern
+
+```javascript
+// Initialize (before Phase 1)
+TodoWrite({todos: [
+  {"content": "Execute style extraction from reference images", "status": "in_progress", "activeForm": "Executing style extraction"},
+  {"content": "Execute style consolidation and token validation", "status": "pending", "activeForm": "Executing style consolidation"},
+  {"content": "Execute UI prototype generation", "status": "pending", "activeForm": "Executing UI generation"},
+  {"content": "Execute design system integration to brainstorming", "status": "pending", "activeForm": "Executing design system integration"}
+]})
+
+// After Phase 1
+TodoWrite({todos: [
+  {"content": "Execute style extraction from reference images", "status": "completed", "activeForm": "Executing style extraction"},
+  {"content": "Execute style consolidation and token validation", "status": "in_progress", "activeForm": "Executing style consolidation"},
+  {"content": "Execute UI prototype generation", "status": "pending", "activeForm": "Executing UI generation"},
+  {"content": "Execute design system integration to brainstorming", "status": "pending", "activeForm": "Executing design system integration"}
+]})
+
+// Continue pattern for Phase 2, 3, 4...
+```
+
+## Parameter Processing
+
+### Session Validation
+```bash
+# Verify active session
+CHECK: .workflow/.active-* marker files
+VERIFY: session_id parameter matches active session
+IF mismatch:
+    ERROR: "Session {session_id} is not active. Active session: {active_session_id}"
+```
+
+### Image Glob Expansion
+```bash
+# Expand glob pattern
+expanded_paths = bash(ls {image_glob})
+IF no files found:
+    ERROR: "No images found matching pattern: {image_glob}"
+VALIDATE: All files are image formats (.png, .jpg, .jpeg, .webp)
+```
+
+### Page List Parsing
+```bash
+# Parse comma-separated page list
+pages = split(page_list, ",")
+TRIM: whitespace from each page name
+VALIDATE: page_list not empty
+```
+
+## Data Flow
+
+```
+User Input
+  ├── session_id
+  ├── image_glob → expanded_image_paths
+  ├── page_list → parsed_pages[]
+  ├── --interactive → interactive_mode (bool)
+  └── --variants → variants_count (int)
+    ↓
+Phase 1: style-extract
+  Input: session_id, expanded_image_paths
+  Output: style-cards.json
+    ↓
+Phase 2: style-consolidate
+  Input: session_id, interactive_mode | auto-select
+  Output: design-tokens.json, style-guide.md, tailwind.config.js
+    ↓
+Phase 3: ui-generate
+  Input: session_id, parsed_pages[], variants_count
+  Output: {page}-variant-{n}.html/css for each page
+    ↓
+Phase 4: design-update
+  Input: session_id
+  Output: Updated synthesis-specification.md, ui-designer/style-guide.md
+    ↓
+Return summary to user
+```
+
+## Error Handling
+
+**Phase Execution Failures**:
+- **Keep phase `in_progress`**: Do not proceed to next phase
+- **Report error to user**: Include specific failure message from command
+- **Provide recovery instructions**: Suggest manual command execution with corrected parameters
+
+**Common Errors**:
+1. **Session not found**: Verify session exists and is active
+2. **No images found**: Check image glob pattern and file paths
+3. **Style extraction failed**: Retry with different images or manual style description
+4. **Consolidation validation errors**: Review validation-report.json and address token issues
+5. **UI generation failed**: Check synthesis-specification.md for requirements clarity
+6. **Integration conflicts**: Review synthesis-specification.md edit conflicts
+
+## Workflow Position
+
+**In Complete Development Flow**:
+```
+/workflow:brainstorm:auto-parallel "{topic}"
+    ↓ Generates synthesis-specification.md (WHAT)
+    ↓
+/workflow:design:auto --session WFS-xxx --images "refs/*.png" --pages "dashboard,auth"
+    ↓ Refines visual design (WHAT → Visual Spec)
+    ↓
+/workflow:plan [--agent] "{task description}"
+    ↓ Generates task breakdown (HOW)
+    ↓
+/workflow:execute
+    ↓ Implements tasks with design system
+```
+
+**Key Benefits**:
+1. **Visual Validation**: Users confirm design before implementation
+2. **Token Enforcement**: Implementation strictly follows design system
+3. **Accessibility**: WCAG AA validated at design phase
+4. **Consistency**: Single source of truth for visual design
+
+## Coordinator Checklist
+
+✅ Initialize TodoWrite before any command execution
+✅ Validate session parameter before Phase 1
+✅ Expand image glob to concrete paths
+✅ Parse page list to array
+✅ Execute Phase 1 immediately (no preliminary analysis)
+✅ Parse style card count from Phase 1 output
+✅ Construct Phase 2 command based on --interactive flag
+✅ Parse token count and validation status from Phase 2
+✅ Construct Phase 3 command with variants parameter
+✅ Parse prototype count from Phase 3 output
+✅ Execute Phase 4 design system integration
+✅ Verify all artifacts updated successfully
+✅ Update TodoWrite after each phase
+✅ After each phase, automatically continue to next phase based on TodoWrite status
+
+## Integration Notes
+
+**Seamless Workflow Transition**:
+- Design phase is **optional but recommended** for UI-heavy projects
+- Can be skipped entirely if visual design is not critical
+- Brainstorming → Plan flow still works without design phase
+- Design artifacts automatically discovered by task-generate if present
+
+**Use Cases**:
+- **Use design workflow**: User-facing applications, design systems, brand-critical UIs
+- **Skip design workflow**: Backend APIs, CLI tools, prototypes, MVPs
+
+**Artifact Discovery**:
+- `task-generate` automatically detects `.design/` directory
+- If present, adds design system to task context.artifacts
+- UI tasks automatically include `load_design_tokens` in flow_control
+
+This design ensures backward compatibility while enabling powerful visual design workflows when needed.

+
+# Design Update Command
+
+## Overview
+Synchronize finalized design system (tokens, style guide, selected prototypes) back to brainstorming artifacts, preparing for `/workflow:plan` phase consumption.
+
+## Core Philosophy
+- **Main Claude Execution**: Direct updates by main Claude (avoid Agent context loss, following synthesis pattern)
+- **Reference-Based Integration**: Use @ references, not content duplication
+- **Synthesis Alignment**: Update synthesis-specification.md UI/UX Guidelines section
+- **UI Designer Sync**: Mirror design system to ui-designer/style-guide.md
+- **Plan-Ready Output**: Ensure design artifacts discoverable by task-generate
+
+## Execution Protocol
+
+### Phase 1: Session & Design System Validation
+```bash
+# Validate session and verify design system completeness
+CHECK: .workflow/.active-* marker files
+VALIDATE: session_id matches active session
+
+VERIFY required artifacts:
+- .design/style-consolidation/design-tokens.json
+- .design/style-consolidation/style-guide.md
+- .design/style-consolidation/tailwind.config.js
+- .design/prototypes/*.html (at least one prototype)
+
+IF --selected-prototypes provided:
+    VALIDATE: Specified prototypes exist
+ELSE:
+    AUTO-SELECT: Use all generated prototypes
+```
+
+### Phase 2: Load Design System Context
+**Direct Claude Code Execution** (no Agent invocation)
+
+```bash
+# Load all design system artifacts
+Read(.workflow/WFS-{session}/.design/style-consolidation/design-tokens.json)
+Read(.workflow/WFS-{session}/.design/style-consolidation/style-guide.md)
+Read(.workflow/WFS-{session}/.design/style-consolidation/style-philosophy.md)
+Read(.workflow/WFS-{session}/.design/style-consolidation/tailwind.config.js)
+
+# Load selected prototype files
+FOR each selected_prototype IN selected_prototypes:
+    Read(.workflow/WFS-{session}/.design/prototypes/{selected_prototype}.html)
+    Read(.workflow/WFS-{session}/.design/prototypes/{selected_prototype}-notes.md)
+
+# Load target brainstorming artifacts
+Read(.workflow/WFS-{session}/.brainstorming/synthesis-specification.md)
+Read(.workflow/WFS-{session}/.brainstorming/ui-designer/analysis.md) [if exists]
+```
+
+### Phase 3: Update Synthesis Specification
+**Direct Write by Main Claude**
+
+Update `.brainstorming/synthesis-specification.md`:
+
+```markdown
+## UI/UX Guidelines
+
+### Design System Reference
+**Finalized Design Tokens**: @../.design/style-consolidation/design-tokens.json
+**Style Guide**: @../.design/style-consolidation/style-guide.md
+**Tailwind Configuration**: @../.design/style-consolidation/tailwind.config.js
+
+### Design Philosophy
+[Insert content from style-philosophy.md]
+
+### Token System Overview
+**Colors**: OKLCH-based color system with semantic naming
+- Brand: primary, secondary, accent
+- Surface: background, elevated, sunken
+- Semantic: success, warning, error, info
+
+**Typography**: {font_family_count} font families, {scale_count}-step scale
+- Heading: {heading_font}
+- Body: {body_font}
+- Monospace: {mono_font}
+
+**Spacing**: {scale_count}-step scale ({min}rem to {max}rem)
+
+**Components**: Border radius, shadows, and component tokens defined
+
+### Implementation Requirements
+**Token Adherence**: All UI implementations MUST use design token CSS custom properties
+**Accessibility**: WCAG AA compliance validated in design-tokens.json
+**Responsive**: Mobile-first design using token-based breakpoints
+**Component Patterns**: Follow patterns documented in style-guide.md
+
+### Reference Prototypes
+[For each selected prototype:]
+- **{page_name}**: @../.design/prototypes/{prototype}.html
+  - Layout: {layout_description from notes}
+  - Components: {component_list from notes}
+  - Token Usage: {token_usage_summary from notes}
+
+### Design System Assets (for task-generate consumption)
+```json
+{
+  "design_tokens": ".design/style-consolidation/design-tokens.json",
+  "style_guide": ".design/style-consolidation/style-guide.md",
+  "tailwind_config": ".design/style-consolidation/tailwind.config.js",
+  "prototypes": [
+    ".design/prototypes/{prototype-1}.html",
+    ".design/prototypes/{prototype-2}.html"
+  ]
+}
+```
+```
+
+**Implementation**:
+```bash
+# Edit synthesis-specification.md
+Edit(
+  file_path=".workflow/WFS-{session}/.brainstorming/synthesis-specification.md",
+  old_string="## UI/UX Guidelines\n[existing content or empty]",
+  new_string="## UI/UX Guidelines\n\n[new design system content with @ references]"
+)
+```
+
+### Phase 4: Update UI Designer Analysis
+**Create or update** `.brainstorming/ui-designer/style-guide.md`:
+
+```markdown
+# UI Designer Style Guide
+
+## Design System Integration
+This style guide integrates the finalized design system from the design refinement phase.
+
+**Source Design Tokens**: @../../.design/style-consolidation/design-tokens.json
+**Source Style Guide**: @../../.design/style-consolidation/style-guide.md
+
+## Design Philosophy
+[Content from style-philosophy.md]
+
+## Design Tokens Reference
+For complete token definitions, see: @../../.design/style-consolidation/design-tokens.json
+
+### Color System
+[Summary of color tokens]
+
+### Typography System
+[Summary of typography tokens]
+
+### Spacing System
+[Summary of spacing tokens]
+
+### Component Tokens
+[Summary of component tokens: border-radius, shadows]
+
+## Component Patterns
+[Reference to style-guide.md component patterns]
+
+## Implementation Guidelines
+1. **Use CSS Custom Properties**: All styles reference design tokens
+2. **Follow Semantic HTML**: Use HTML5 semantic elements
+3. **Maintain Accessibility**: WCAG AA compliance required
+4. **Responsive Design**: Mobile-first with token-based breakpoints
+
+## Reference Prototypes
+[Links to selected prototypes with descriptions]
+
+---
+*Auto-generated by /workflow:design:design-update*
+*Last updated: {timestamp}*
+```
+
+**Implementation**:
+```bash
+Write(
+  file_path=".workflow/WFS-{session}/.brainstorming/ui-designer/style-guide.md",
+  content="[generated style guide content with @ references]"
+)
+```
+
+### Phase 5: Create Design System Symlinks (Optional)
+**For easier task-generate discovery**
+
+```bash
+# Create read-only mirror of key design files in brainstorming space
+bash(cd .workflow/WFS-{session}/.brainstorming && \
+     ln -s ../.design/style-consolidation/design-tokens.json design-tokens.json && \
+     ln -s ../.design/style-consolidation/style-guide.md design-style-guide.md)
+```
+
+### Phase 6: TodoWrite Integration
+```javascript
+TodoWrite({
+  todos: [
+    {
+      content: "Validate session and design system completeness",
+      status: "completed",
+      activeForm: "Validating design system"
+    },

+  ],
+  "output_to": "design_system_context",
+  "on_error": "warn"
+}
+```
+
+## Error Handling
+- **Missing design tokens**: Error, run `/workflow:design:style-consolidate` first
+- **Missing prototypes**: Error, run `/workflow:design:ui-generate` first
+- **synthesis-specification.md not found**: Warning, create minimal version
+- **Edit conflicts**: Preserve existing content, append design system section
+- **Symlink failures**: Warning only, continue with @ references
+
+## Validation Checks
+After update, verify:
+- [ ] synthesis-specification.md contains UI/UX Guidelines section
+- [ ] UI/UX Guidelines include @ references to design system files
+- [ ] ui-designer/style-guide.md created or updated
+- [ ] design-tokens.json symlink created (if applicable)
+- [ ] All referenced files exist and are readable
+
+## Integration Points
+- **Input**: design-tokens.json, style-guide.md, prototypes from design phase
+- **Output**: Updated synthesis-specification.md, ui-designer/style-guide.md
+- **Next Phase**: `/workflow:plan` can now discover and utilize design system
+
+## Completion Message
+
+```
+Design system update complete for session: WFS-{session}
+
+Updated artifacts:
+✓ synthesis-specification.md - UI/UX Guidelines section added
+✓ ui-designer/style-guide.md - Comprehensive style guide created
+✓ Design system references: @ notation for all design files
+
+Design system assets ready for task generation:
+- design-tokens.json ({token_count} tokens)
+- style-guide.md (comprehensive component patterns)
+- tailwind.config.js (Tailwind theme extension)
+- {prototype_count} reference prototypes
+
+Next: /workflow:plan [--agent] "<task description>"
+      The plan phase will automatically discover and utilize the design system.
+```
+
+## Main Claude Direct Execution Rationale
+
+This command is executed directly by main Claude (not delegated to an Agent) because:
+
+1. **Context Preservation**: Main Claude has full session context and conversation memory
+2. **Integration Complexity**: Requires understanding multiple artifact relationships
+3. **Reference Accuracy**: @ reference generation needs precise path resolution
+4. **Synthesis Pattern**: Follows the same direct-execution pattern as `/workflow:brainstorm:synthesis`
+5. **Minimal Transformation**: Primarily reference integration, not generative analysis
+6. **Error Recovery**: Main Claude can better handle edit conflicts and missing files
+
+This approach ensures reliable, context-aware integration without Agent handoff overhead.

+# Style Consolidation Command
+
+## Overview
+Consolidate user-selected style variants into a unified, production-ready design system with validated CSS tokens and comprehensive style guide.
+
+## Core Philosophy
+- **User-Driven Selection**: Interactive mode for visual style card selection
+- **Gemini Clustering**: Semantic naming and style philosophy consolidation
+- **Codex Validation**: Token consistency, coverage, and accessibility checks
+- **Design System Output**: production-ready tokens + comprehensive style guide
+
+## Execution Protocol
+
+### Phase 1: Session & Style Cards Loading
+```bash
+# Validate session and load extracted style cards
+CHECK: .workflow/.active-* marker files
+VALIDATE: session_id matches active session
+VERIFY: .design/style-extraction/style-cards.json exists
+LOAD: style-cards.json for user selection
+```
+
+### Phase 2: User Selection (Interactive Mode)
+**Interactive Mode**: `--interactive` flag enables visual selection interface
+
+```bash
+IF --interactive:
+    DISPLAY: Style card previews with descriptions
+    PROMPT: "Select preferred style variants (comma-separated IDs):"
+    COLLECT: user_selection (e.g., "variant-1,variant-3")
+ELSE IF --variants provided:
+    PARSE: variant IDs from --variants flag
+ELSE:
+    ERROR: "Must provide either --interactive or --variants parameter"
+```
+
+### Phase 3: Gemini Style Philosophy Consolidation
+**Agent Invocation**: Task(conceptual-planning-agent) with Gemini capabilities
+
+```bash
+Task(conceptual-planning-agent): "
+[FLOW_CONTROL]
+
+Consolidate selected style variants into unified design philosophy

+# Style Extraction Command
+
+## Overview
+Extract design style elements from reference images using a hybrid approach: Gemini Vision for semantic understanding and Codex for structured CSS token generation.
+
+## Core Philosophy
+- **Visual Semantic Understanding**: Gemini Vision analyzes design style, typography, and composition
+- **Structured Token Generation**: Codex converts semantic analysis to OKLCH + CSS variables + Tailwind config
+- **Style Card System**: Generate reusable style cards for consolidation phase
+- **Multi-Image Support**: Process multiple reference images and extract common patterns
+
+## Execution Protocol
+
+### Phase 1: Session & Input Validation
+```bash
+# Validate session and locate images
+CHECK: .workflow/.active-* marker files
+VALIDATE: session_id matches active session
+EXPAND: glob pattern to concrete image paths
+VERIFY: at least one image file exists
+```

+
+## Error Handling
+- **No design tokens found**: Run `/workflow:design:style-consolidate` first
+- **Invalid page names**: List available pages from synthesis-specification.md
+- **Codex generation errors**: Retry with simplified requirements, report warnings
+- **Token reference errors**: Validate all CSS against design-tokens.json
+
+## Quality Checks
+After generation, verify:
+- [ ] All CSS values reference design token custom properties
+- [ ] No hardcoded colors, spacing, or typography
+- [ ] Semantic HTML structure
+- [ ] Accessibility attributes present
+- [ ] Responsive design implemented
+- [ ] Token-driven styling consistent across variants
+
+## Integration Points
+- **Input**: design-tokens.json, style-guide.md, synthesis-specification.md
+- **Output**: HTML/CSS prototypes for `/workflow:design:design-update`
+- **Context**: ui-designer/analysis.md for UX guidance
+
+## Next Steps
+After successful generation:
+```
+UI prototypes generated for session: WFS-{session}
+Pages: {page_list}
+Variants per page: {variants_count}
+
+Generated files:
+- {count} HTML prototypes
+- {count} CSS files (token-driven)
+- {count} implementation notes
+
+Review prototypes and select preferred variants:
+Location: .workflow/WFS-{session}/.design/prototypes/
+
+Next: /workflow:design:design-update --session WFS-{session}
+```

+# Design Tokens Schema Specification
+
+## Overview
+Standardized JSON schema for design tokens used in `/workflow:design/*` commands. Ensures consistency across style extraction, consolidation, and UI generation phases.
+
+## Core Principles
+
+1. **OKLCH Color Format**: All colors use OKLCH color space for perceptual uniformity
+2. **Semantic Naming**: User-centric token names (brand-primary, surface-elevated, not color-1, bg-2)
+3. **rem-Based Sizing**: All spacing and typography use rem units for scalability
+4. **Comprehensive Coverage**: Complete token set for production-ready design systems
+5. **Accessibility First**: WCAG AA compliance validated and documented
+

+
+## Validation Requirements
+
+### Color Validation
+- All colors MUST use OKLCH format
+- Alpha channel optional (defaults to 1)
+- Lightness: 0-1 (0% to 100%)
+- Chroma: 0-0.4 (typical range, can exceed for vibrant colors)
+- Hue: 0-360 (degrees)
+
+### Accessibility Validation
+- Text on background: minimum 4.5:1 contrast (WCAG AA)
+- Large text (18pt+ or 14pt+ bold): minimum 3:1 contrast
+- UI components: minimum 3:1 contrast
+- Non-text focus indicators: minimum 3:1 contrast
+
+### Consistency Validation
+- Spacing scale maintains consistent ratio (e.g., 1.5x or 2x progression)
+- Typography scale follows modular scale principles
+- Border radius values progress logically
+- Shadow layers increase in offset and blur systematically
+
+## Usage in Commands
+
+### style-extract Output
+Generates initial `design-tokens.json` from visual analysis
+
+### style-consolidate Output
+Finalizes validated `design-tokens.json` with accessibility data
+
+### ui-generate Input
+Reads `design-tokens.json` to generate CSS custom properties
+
+### design-update Integration
+References `design-tokens.json` path in synthesis-specification.md
+
+## Version History
+
+- **1.0.0**: Initial schema with OKLCH colors, semantic naming, WCAG AA validation
