# UI Design Imitate-Auto Workflow Command

## Overview & Execution Model

**Fully autonomous design orchestrator**: Efficiently create UI prototypes through sequential execution from design token extraction to system integration.

**Direct Input Strategy**: Accepts local code files and images:
- **Code Files**: Detect file paths in `--prompt` parameter
- **Images**: Reference images via `--images` glob pattern
- **Hybrid**: Combine both code and visual inputs

**Autonomous Flow** (⚠️ CONTINUOUS EXECUTION - DO NOT STOP):
1. User triggers: `/workflow:ui-design:imitate-auto [--input "..."]`
2. Phase 0: Initialize and detect input sources
3. Phase 2: Style extraction → **Attach tasks → Execute → Collapse** → Auto-continues
4. Phase 2.3: Animation extraction → **Attach tasks → Execute → Collapse** → Auto-continues
5. Phase 2.5: Layout extraction → **Attach tasks → Execute → Collapse** → Auto-continues
6. Phase 3: Batch UI assembly → **Attach tasks → Execute → Collapse** → Auto-continues
7. Phase 4: Design system integration → **Execute orchestrator task** → Reports completion

**Phase Transition Mechanism**:
- **Task Attachment**: SlashCommand dispatch **ATTACHES** tasks to current workflow
- **Task Execution**: Orchestrator **EXECUTES** these attached tasks itself
- **Task Collapse**: After tasks complete, collapse them into phase summary
- **Phase Transition**: Automatically execute next phase after collapsing
- No user interaction required after initial parameter parsing

**Auto-Continue Mechanism**: TodoWrite tracks phase status with dynamic task attachment/collapse. After executing all attached tasks, you MUST immediately collapse them, restore phase summary, and execute the next phase. No user intervention required. The workflow is NOT complete until reaching Phase 4.

**Task Attachment Model**: SlashCommand dispatch is NOT delegation - it's task expansion. The orchestrator executes these attached tasks itself, not waiting for external completion.

## Execution Process

```
Input Parsing:
   ├─ Parse flags: --input, --session (legacy: --images, --prompt)
   └─ Decision (input detection):
      ├─ Contains * or glob matches → images_input (visual)
      ├─ File/directory exists → code import source
      └─ Pure text → design prompt

Phase 0: Parameter Parsing & Input Detection
   ├─ Step 1: Normalize parameters (legacy deprecation warning)
   ├─ Step 2: Detect design source (hybrid | code_only | visual_only)
   └─ Step 3: Initialize directories and metadata

Phase 0.5: Code Import (Conditional)
   └─ Decision (design_source):
      ├─ hybrid → Dispatch /workflow:ui-design:import-from-code
      └─ Other → Skip to Phase 2

Phase 2: Style Extraction
   └─ Decision (skip_style):
      ├─ code_only AND style_complete → Use code import
      └─ Otherwise → Dispatch /workflow:ui-design:style-extract

Phase 2.3: Animation Extraction
   └─ Decision (skip_animation):
      ├─ code_only AND animation_complete → Use code import
      └─ Otherwise → Dispatch /workflow:ui-design:animation-extract

Phase 2.5: Layout Extraction
   └─ Decision (skip_layout):
      ├─ code_only AND layout_complete → Use code import
      └─ Otherwise → Dispatch /workflow:ui-design:layout-extract

Phase 3: UI Assembly
   └─ Dispatch /workflow:ui-design:generate

Phase 4: Design System Integration
   └─ Decision (session_id):
      ├─ Provided → Dispatch /workflow:ui-design:update
      └─ Not provided → Standalone completion
```

## Core Rules

1. **Start Immediately**: TodoWrite initialization → Phase 2 execution
2. **No Preliminary Validation**: Sub-commands handle their own validation
3. **Parse & Pass**: Extract data from each output for next phase
4. **Track Progress**: Update TodoWrite dynamically with task attachment/collapse pattern
5. **⚠️ CRITICAL: Task Attachment Model** - SlashCommand dispatch **ATTACHES** tasks to current workflow. Orchestrator **EXECUTES** these attached tasks itself, not waiting for external completion. This is NOT delegation - it's task expansion.
6. **⚠️ CRITICAL: DO NOT STOP** - This is a continuous multi-phase workflow. After executing all attached tasks, you MUST immediately collapse them and execute the next phase. Workflow is NOT complete until Phase 4.

## Parameter Requirements

**Recommended Parameter**:
- `--input "<value>"`: Unified input source (auto-detects type)
  - **Glob pattern** (images): `"design-refs/*"`, `"screenshots/*.png"`
  - **File/directory path** (code): `"./src/components"`, `"/path/to/styles"`
  - **Text description** (prompt): `"Focus on dark mode"`, `"Emphasize minimalist design"`
  - **Combination**: `"design-refs/* modern dashboard style"` (glob + description)
  - Multiple inputs: Separate with `|` → `"design-refs/*|modern style"`

**Detection Logic**:
- Contains `*` or matches existing files → **glob pattern** (images)
- Existing file/directory path → **code import**
- Pure text without paths → **design prompt**
- Contains `|` separator → **multiple inputs** (glob|prompt or path|prompt)

**Legacy Parameters** (deprecated, use `--input` instead):
- `--images "<glob>"`: Reference image paths (shows deprecation warning)
- `--prompt "<desc>"`: Design description (shows deprecation warning)

**Optional Parameters**:
- `--session <id>`: Workflow session ID
  - Integrate into existing session (`.workflow/active/WFS-{session}/`)
  - Enable automatic design system integration (Phase 4)
  - If not provided: standalone mode (`.workflow/`)

**Input Rules**:
- Must provide: `--input` OR (legacy: `--images`/`--prompt`)
- `--input` can combine multiple input types
- File paths are automatically detected and trigger code import

## Execution Modes

**Input Sources**:
- **Code Files**: Automatically detected from `--prompt` file paths
  - Triggers `/workflow:ui-design:import-from-code` for token extraction
  - Analyzes existing CSS/JS/HTML files
- **Visual Input**: Images via `--images` glob pattern
  - Reference images for style extraction
  - Screenshots or design mockups
- **Hybrid Mode**: Combines code import with visual supplements
  - Code provides base tokens
  - Images supplement missing design elements

**Token Processing**:
- **Direct Generation**: Complete design systems generated in style-extract phase
  - Production-ready design-tokens.json with WCAG compliance
  - Complete style-guide.md documentation
  - No separate consolidation step required (~30-60s faster)

**Session Integration**:
- `--session` flag determines session integration or standalone execution
- Integrated: Design system automatically added to session artifacts
- Standalone: Output in `.workflow/active/{run_id}/`

    TodoWrite(mark_completed: "Extract layout", mark_in_progress: "Assemble UI")
```

### Phase 3: UI Assembly

**Step 3.1: Dispatch** - Assemble UI prototypes from design tokens and layout templates

```javascript
REPORT: "🚀 Phase 3: UI Assembly"
generate_command = f"/workflow:ui-design:generate --design-id \"{design_id}\""

# SlashCommand dispatch ATTACHES generate's tasks to current workflow

# After executing all attached tasks, collapse them into phase summary
TodoWrite(mark_completed: "Assemble UI", mark_in_progress: session_id ? "Integrate design system" : "Completion")

### Phase 4: Design System Integration

**Step 4.1: Dispatch** - Integrate design system into workflow session

```javascript
IF session_id:
    REPORT: "🚀 Phase 4: Design System Integration"
    update_command = f"/workflow:ui-design:update --session {session_id}"

    # SlashCommand dispatch ATTACHES update's tasks to current workflow

// ⚠️ CRITICAL: Dynamic TodoWrite task attachment strategy:
//
// **Key Concept**: SlashCommand dispatch ATTACHES tasks to current workflow.
// Orchestrator EXECUTES these attached tasks itself, not waiting for external completion.
//
// Phase 2-4 SlashCommand Dispatch Pattern (when tasks are attached):
// Example - Phase 2 with sub-tasks:
// [
//   {"content": "Phase 0: Initialize and Detect Design Source", "status": "completed", "activeForm": "Initializing"},
//   {"content": "Phase 2: Style Extraction", "status": "in_progress", "activeForm": "Extracting style"},
//   {"content": "  → Analyze design references", "status": "in_progress", "activeForm": "Analyzing references"},
//   {"content": "  → Generate design tokens", "status": "pending", "activeForm": "Generating tokens"},
//   {"content": "  → Create style guide", "status": "pending", "activeForm": "Creating guide"},
//   {"content": "Phase 2.3: Animation Extraction", "status": "pending", "activeForm": "Extracting animation"},
//   ...
// ]
//
// After sub-tasks complete, COLLAPSE back to:
// [
//   {"content": "Phase 0: Initialize and Detect Design Source", "status": "completed", "activeForm": "Initializing"},
//   {"content": "Phase 2: Style Extraction", "status": "completed", "activeForm": "Extracting style"},
//   {"content": "Phase 2.3: Animation Extraction", "status": "in_progress", "activeForm": "Extracting animation"},
//   ...
// ]
//
```

## Error Handling

### Pre-execution Checks
- **Input validation**: Must provide at least one of --images or --prompt
- **Design source detection**: Error if no valid inputs found
- **Code import failure**: Fallback to visual-only mode in hybrid, error in code-only mode

### Phase-Specific Errors
- **Code import failure (Phase 0.5)**:
  - code_only mode: Terminate with clear error
  - hybrid mode: Warn and fallback to visual-only mode

- **Style extraction failure (Phase 2)**:
  - If extract fails: Terminate with clear error
  - If design-tokens.json missing: Terminate with debugging info

- **Animation extraction failure (Phase 2.3)**:
  - Non-critical: Warn but continue
  - Can proceed without animation tokens

- **Layout extraction failure (Phase 2.5)**:
  - If extract fails: Terminate with error
  - Need layout templates for assembly

- **UI generation failure (Phase 3)**:
  - If generate fails: Terminate with error
  - If generated_count < expected: Warn but proceed

- **Integration failure (Phase 4)**:
  - Non-blocking: Warn but don't terminate
  - Prototypes already available

### Recovery Strategies
- **Code import failure**: Automatic fallback to visual-only in hybrid mode
- **Generate failure**: Report specific failures, user can re-generate individually
- **Integration failure**: Prototypes still usable, can integrate manually

## Integration Points

- **Input**: `--images` (glob pattern) and/or `--prompt` (text/file paths) + optional `--session`
- **Output**: Complete design system in `{base_path}/` (style-extraction, layout-extraction, prototypes)
- **Sub-commands Dispatched**:
  1. `/workflow:ui-design:import-from-code` (Phase 0.5, conditional - if code files detected)
  2. `/workflow:ui-design:style-extract` (Phase 2 - complete design systems)
  3. `/workflow:ui-design:animation-extract` (Phase 2.3 - animation tokens)
  4. `/workflow:ui-design:layout-extract` (Phase 2.5 - structure templates)
  5. `/workflow:ui-design:generate` (Phase 3 - pure assembly)
  6. `/workflow:ui-design:update` (Phase 4, if --session)
