refactor: optimize docs.md workflow command structure

- Simplify Pre-Planning Analysis (Phase 3) - remove heavy analysis, use lightweight check
- Add TodoWrite tracking mechanism for progress monitoring
- Add complete execution flow diagrams (Planning + Execution phases)
- Restore full JSON task templates with all 5 fields
- Fix template reference method: use $(cat template.txt) instead of "..."
- Simplify flow diagrams from ASCII boxes to arrow-based format
- Add visual status symbols (✅🔄⏳) for TodoWrite tracking
- Reorganize document structure, eliminate duplicate content
- Reduce document from 726 to 590 lines (19% reduction)
- Maintain all core functionality and implementation details

Changes:
- Phase 3: Lightweight docs assessment vs full pre-analysis
- Phase 4: Add TodoWrite setup with status tracking
- Task Templates: Complete JSON structures for 4 task types
- Execution Flow: Simple arrow diagrams for clarity
- TodoWrite: Visual status progression examples
- Overall: Better organized, more maintainable

+
+### Phase Details
+
+#### Phase 1: Session Initialization
 ```bash
-# 1. Parse user input
+# Parse arguments and create session structure
 doc_type="all"  # architecture|api|all
 tool="gemini"   # gemini|qwen|codex (default: gemini)
 scope=""        # optional path filter
 
-# Extract from command arguments
-[[ "$*" == *"architecture"* ]] && doc_type="architecture"
-[[ "$*" == *"api"* ]] && doc_type="api"
-[[ "$*" == *"--tool qwen"* ]] && tool="qwen"
-[[ "$*" == *"--tool codex"* ]] && tool="codex"
-[[ "$*" =~ --scope[[:space:]]+([^[:space:]]+) ]] && scope="${BASH_REMATCH[1]}"
-
-# 2. Create session structure
 timestamp=$(date +%Y%m%d-%H%M%S)
 session_dir=".workflow/WFS-docs-${timestamp}"
 mkdir -p "${session_dir}"/{.task,.process,.summaries}
-
-# 3. Create active marker
 touch ".workflow/.active-WFS-docs-${timestamp}"
 ```
 
-### Phase 2: Project Structure Analysis (MANDATORY)
+#### 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)
-
-# Parse module information
 # Format: depth:N|path:<PATH>|files:N|size:N|has_claude:yes/no
 ```
 
-### Phase 3: Pre-Planning Analysis (Optional)
+#### Phase 3: Quick Documentation Assessment
-Uses selected tool to analyze existing documentation and suggest improvements:
-
 ```bash
-if [[ "$tool" == "codex" ]]; then
+# Lightweight check - no heavy analysis
-    # Codex: Direct exec
+existing_docs=$(find . -maxdepth 2 -name "*.md" -not -path "./.workflow/*" | wc -l)
-    codex -C . --full-auto exec "
+
-    PURPOSE: Analyze documentation strategy
+if [[ $existing_docs -gt 5 ]]; then
-    TASK: Review existing docs and suggest improvements for ${doc_type}
+    find . -maxdepth 3 -name "*.md" > "${session_dir}/.process/existing-docs.txt"
-    MODE: analysis
-    CONTEXT: @{CLAUDE.md,**/*CLAUDE.md,docs/**/*}
-    EXPECTED: Gap analysis and recommendations
-    RULES: Focus on clarity, completeness, architectural alignment
-    " --skip-git-repo-check > "${session_dir}/.process/pre-analysis.md"

+# Record strategy

+**Type**: ${doc_type}
+**Tool**: ${tool}
+**Scope**: ${scope:-"Full project"}
+EOF
 ```
 
-### Phase 4: Task Decomposition
+#### 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 for efficiency)
+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
 
-**Task Count Formula**:
+**TodoWrite Setup**:
 ```
-base_tasks = 1 (system overview)
+✅ Session initialization (completed)
-+ (doc_type includes "architecture" ? 1 : 0)
+⏳ IMPL-001: Project Overview (pending)
-+ (doc_type includes "api" ? 1 : 0)
+⏳ IMPL-002: Module 'auth' (pending)
-+ ceil(module_count / 3)
+⏳ IMPL-003: Module 'api' (pending)
+⏳ IMPL-004: Architecture Documentation (pending)
+⏳ IMPL-005: API Documentation (pending)
 ```
 
-### Phase 5: Task JSON Generation
+#### Phase 5: Task JSON Generation
 
 Each task follows the 5-field schema with detailed flow_control.
 
-#### Command Generation Logic
+**Command Generation Logic**:
-
-At planning time, commands are built based on the `$tool` variable:
-
 ```bash
-# Build tool-specific command for pre_analysis step
+# Build tool-specific command at planning time
-build_analysis_command() {
+if [[ "$tool" == "codex" ]]; then
-    local step_name="$1"
+    cmd="codex -C ${dir} --full-auto exec \"...\""
-    local context_path="$2"
+else
-    local template_path="$3"
+    cmd="bash(cd ${dir} && ~/.claude/scripts/${tool}-wrapper -p \"...\")"
-    local output_var="$4"
+fi
-
-    if [[ "$tool" == "codex" ]]; then
-        # Codex: direct exec with -C directory
-        echo "codex -C ${context_path} --full-auto exec \"PURPOSE: ...\\nTASK: ...\\nMODE: analysis\\nCONTEXT: @{**/*}\\nEXPECTED: ...\\nRULES: \$(cat ${template_path})\" --skip-git-repo-check"
-    else
-        # Gemini/Qwen: wrapper with -p
-        echo "bash(cd ${context_path} && ~/.claude/scripts/${tool}-wrapper -p \"PURPOSE: ...\\nTASK: ...\\nMODE: analysis\\nCONTEXT: @{**/*}\\nEXPECTED: ...\\nRULES: \$(cat ${template_path})\")"
-    fi
-}
-
-# Usage in task JSON generation
-analyze_cmd=$(build_analysis_command "analyze_module" "src/auth" \
-    "~/.claude/workflows/cli-templates/prompts/documentation/module-documentation.txt" \
-    "module_analysis")
 ```
 
-**Key Points**:
+## Task Templates
-- **Default tool**: `gemini`
-- **Template reference**: Use `$(cat template_path.txt)` to embed template content
-- **One command per step**: No conditional blocks, command is concrete
-- **Tool selection happens at planning time**, not execution time

+## 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 user to complete or pause current session
+- **Active session exists**: Prompt to complete or pause
 - **Tool unavailable**: Fall back to gemini
 
-## Next Steps
-
-After running `/workflow:docs`:
-1. Review generated `IMPL_PLAN.md` and `TODO_LIST.md`
-2. Execute tasks using `/workflow:execute IMPL-NNN`
-3. Tasks can be parallelized (modules) or run sequentially
-4. Review completed documentation in `.workflow/docs/`
-
 ## Key Benefits
 
 ### Clear Separation of Concerns
-- **Planning** (docs.md): Session creation, task decomposition, no content generation
+- **Planning**: Session creation, task decomposition (this command)
-- **Execution** (doc-generator.md): Content generation, template application, quality assurance
+- **Execution**: Content generation, quality assurance (doc-generator agent)
 
 ### Scalable Task Management
-- Each documentation task is independent and self-contained
+- Independent, self-contained tasks
-- Tasks can be parallelized for faster completion
+- Parallelizable module documentation
-- Clear dependencies (e.g., architecture requires module docs)
+- Clear dependencies (architecture needs modules)
 
 ### Template-Driven Consistency
 - All documentation follows standard templates
-- Templates are reusable and maintainable
+- Reusable and maintainable
-- Easy to update documentation standards
+- Easy to update standards
 
 ### Full Context for Execution
 - Each task JSON contains complete instructions
 - flow_control defines exact analysis steps
-- Conditional tool selection for flexibility
+- Tool selection for flexibility
