description: Documentation planning and orchestration - creates structured documentation tasks for execution
usage: /workflow:docs <type> [options]
argument-hint: "architecture"|"api"|"all" [--tool <gemini|qwen|codex>] [--scope <path>]
examples:
  - /workflow:docs all                          # Complete documentation (gemini default)

# Workflow Documentation Command

## Purpose

**`/workflow:docs` is a pure planner/orchestrator** - it analyzes project structure, decomposes documentation work into tasks, and generates execution plans. It does **NOT** generate any documentation content itself.

**Key Principle**: Separation of Concerns
- **docs.md** → Planning, session creation, task generation
- **doc-generator.md** → Execution, content generation, quality assurance

## Usage

```bash
/workflow:docs <type> [--tool <gemini|qwen|codex>] [--scope <path>]
```

### Parameters

- **type**: `architecture` | `api` | `all` (required)
  - `architecture`: System design, module interactions, patterns
  - `api`: Endpoint documentation, API specifications
  - `all`: Complete documentation suite

- **--tool**: `gemini` | `qwen` | `codex` (optional, default: gemini)
  - `gemini`: Comprehensive documentation, pattern recognition
  - `qwen`: Architecture analysis, system design focus
  - `codex`: Implementation validation, code quality

- **--scope**: Directory path filter (optional)

## Planning Workflow

### Complete Execution Flow

```
/workflow:docs [type] [--tool] [--scope]
    ↓
Phase 1: Init Session → Create session dir & active marker
    ↓
Phase 2: Module Analysis → Run get_modules_by_depth.sh
    ↓
Phase 3: Quick Assess → Check existing docs
    ↓
Phase 4: Decompose → Create task list & TodoWrite
    ↓
Phase 5: Generate Tasks → Build IMPL-*.json & plans
    ↓
✅ Planning Complete → Show TodoWrite status
```

### Phase Details

#### Phase 1: Session Initialization
```bash
# Parse arguments and create session structure
doc_type="all"  # architecture|api|all
tool="gemini"   # gemini|qwen|codex (default: gemini)
scope=""        # optional path filter

timestamp=$(date +%Y%m%d-%H%M%S)
session_dir=".workflow/WFS-docs-${timestamp}"
mkdir -p "${session_dir}"/{.task,.process,.summaries}
touch ".workflow/.active-WFS-docs-${timestamp}"
```

#### Phase 2: Project Structure Analysis (MANDATORY)
```bash
# Run get_modules_by_depth.sh for module hierarchy
module_data=$(~/.claude/scripts/get_modules_by_depth.sh)
# Format: depth:N|path:<PATH>|files:N|size:N|has_claude:yes/no
```

#### Phase 3: Quick Documentation Assessment
```bash
# Lightweight check - no heavy analysis
existing_docs=$(find . -maxdepth 2 -name "*.md" -not -path "./.workflow/*" | wc -l)

if [[ $existing_docs -gt 5 ]]; then
    find . -maxdepth 3 -name "*.md" > "${session_dir}/.process/existing-docs.txt"
fi

# Record strategy
cat > "${session_dir}/.process/strategy.md" <<EOF
**Type**: ${doc_type}
**Tool**: ${tool}
**Scope**: ${scope:-"Full project"}
EOF
```

#### Phase 4: Task Decomposition & TodoWrite Setup

**Decomposition Strategy**:
1. **Always create**: System Overview task (IMPL-001)
2. **If architecture/all**: Architecture Documentation task
3. **If api/all**: Unified API Documentation task
4. **For each module**: Module Documentation task (grouped)

**Grouping Rules**:
- Max 3 modules per task
- Max 30 files per task
- Group by dependency depth and functional similarity

**TodoWrite Setup**:
```
✅ Session initialization (completed)
⏳ IMPL-001: Project Overview (pending)
⏳ IMPL-002: Module 'auth' (pending)
⏳ IMPL-003: Module 'api' (pending)
⏳ IMPL-004: Architecture Documentation (pending)
⏳ IMPL-005: API Documentation (pending)
```

#### Phase 5: Task JSON Generation

Each task follows the 5-field schema with detailed flow_control.

**Command Generation Logic**:
```bash
# Build tool-specific command at planning time
if [[ "$tool" == "codex" ]]; then
    cmd="codex -C ${dir} --full-auto exec \"...\""
else
    cmd="bash(cd ${dir} && ~/.claude/scripts/${tool}-wrapper -p \"...\")"
fi
```

### IMPL_PLAN.md
```markdown
# Documentation Implementation Plan

**Session**: WFS-docs-[timestamp]
**Type**: [architecture|api|all]
**Tool**: [gemini|qwen|codex]

## Task Breakdown

### IMPL-001: System Overview
- **Output**: .workflow/docs/README.md
- **Template**: project-overview.txt

### IMPL-002+: Module Documentation
- **Modules**: [list]
- **Template**: module-documentation.txt

### IMPL-N: Architecture/API (if requested)
- **Template**: architecture.txt / api-reference.txt

## Execution Order
1. IMPL-001 (Foundation)
2. IMPL-002 to IMPL-[M] (Modules - can parallelize)
3. IMPL-[M+1] (Architecture - needs modules)
4. IMPL-[N] (API - can run after IMPL-001)
```

### TODO_LIST.md
```markdown
# Documentation Progress Tracker

- [ ] **IMPL-001**: Generate Project Overview
- [ ] **IMPL-002**: Document Module: 'auth'
- [ ] **IMPL-003**: Document Module: 'api'
- [ ] **IMPL-004**: Generate Architecture Documentation
- [ ] **IMPL-005**: Generate Unified API Documentation

## Execution
```bash
/workflow:execute IMPL-001
/workflow:execute IMPL-002
# ...
```
```

## Execution Phase

### Via /workflow:execute

```
For Each Task (IMPL-001, IMPL-002, ...):

/workflow:execute IMPL-NNN
    ↓
TodoWrite: pending → in_progress
    ↓
Execute flow_control (pre_analysis steps)
    ↓
Generate Documentation (apply template)
    ↓
TodoWrite: in_progress → completed
    ↓
✅ Task Complete
```

### TodoWrite Status Tracking

**Planning Phase**:
```
✅ Session initialization (completed)
⏳ IMPL-001: Project Overview (pending)
⏳ IMPL-002: Module 'auth' (pending)
```

**Execution Phase**:
```
Executing IMPL-001:
✅ Session initialization
🔄 IMPL-001: Project Overview (in_progress)
⏳ IMPL-002: Module 'auth'

After IMPL-001:
✅ Session initialization
✅ IMPL-001: Project Overview (completed)
🔄 IMPL-002: Module 'auth' (in_progress)
```

## Documentation Output

### Final Structure
```

```

## Next Steps

### 1. Review Planning Output
```bash
cat .workflow/WFS-docs-*/IMPL_PLAN.md
cat .workflow/WFS-docs-*/TODO_LIST.md
```

### 2. Execute Documentation Tasks
```bash
# Sequential (recommended)
/workflow:execute IMPL-001  # System overview first
/workflow:execute IMPL-002  # Module docs
/workflow:execute IMPL-003
/workflow:execute IMPL-004  # Architecture
/workflow:execute IMPL-005  # API docs

# Parallel (module docs only)
/workflow:execute IMPL-002 &
/workflow:execute IMPL-003 &
wait
```

### 3. Review Generated Documentation
```bash
ls -lah .workflow/docs/
cat .workflow/docs/README.md
```

### 4. TodoWrite Progress
- Planning: All tasks `pending`
- Execution: `pending` → `in_progress` → `completed`
- Real-time status updates via TodoWrite

## Error Handling

- **No modules found**: Create only IMPL-001 (system overview)
- **Scope path invalid**: Show error and exit
- **Active session exists**: Prompt to complete or pause
- **Tool unavailable**: Fall back to gemini

## Key Benefits

### Clear Separation of Concerns
- **Planning**: Session creation, task decomposition (this command)
- **Execution**: Content generation, quality assurance (doc-generator agent)

### Scalable Task Management
- Independent, self-contained tasks
- Parallelizable module documentation
- Clear dependencies (architecture needs modules)

### Template-Driven Consistency
- All documentation follows standard templates
- Reusable and maintainable
- Easy to update standards

### Full Context for Execution
- Each task JSON contains complete instructions
- flow_control defines exact analysis steps
- Tool selection for flexibility
