# Documentation Workflow (/memory:docs)

## Overview
Lightweight planner that analyzes project structure, decomposes documentation work into tasks, and generates execution plans. Does NOT generate documentation content itself - delegates to doc-generator agent.

**Execution Strategy**:
- **Dynamic Task Grouping**: Level 1 tasks dynamically grouped by directory count (max 2 dirs/task, ≤5 docs/task)
- **Parallel Execution**: Multiple Level 1 tasks execute concurrently for faster completion
- **Pre-computed Analysis**: Phase 2 performs unified analysis once, stored in `.process/` for reuse
- **Efficient Data Loading**: All existing docs loaded once in Phase 2, shared across tasks

**Documentation Output**: All generated documentation is placed in `.workflow/docs/{project_name}/` directory with **mirrored project structure**. For example:
- Project: `my_app`
- Source: `my_app/src/core/` → Docs: `.workflow/docs/my_app/src/core/API.md`
- Source: `my_app/src/modules/auth/` → Docs: `.workflow/docs/my_app/src/modules/auth/API.md`

**Two Execution Modes**:
- **Default (Agent Mode)**: CLI analyzes in `pre_analysis` (MODE=analysis), agent writes docs in `implementation_approach`
- **--cli-execute (CLI Mode)**: CLI generates docs in `implementation_approach` (MODE=write), agent executes CLI commands

## Path Mirroring Strategy

**Principle**: Documentation structure **mirrors** source code structure under project-specific directory.

| Source Path | Project Name | Documentation Path |
|------------|--------------|-------------------|
| `my_app/src/core/` | `my_app` | `.workflow/docs/my_app/src/core/API.md` |
| `my_app/src/modules/auth/` | `my_app` | `.workflow/docs/my_app/src/modules/auth/API.md` |
| `another_project/lib/utils/` | `another_project` | `.workflow/docs/another_project/lib/utils/API.md` |

**Benefits**:
- Easy to locate documentation for any source file
- Maintains logical organization
- Clear 1:1 mapping between code and docs
- Supports any project structure (src/, lib/, packages/, etc.)

## Parameters

```bash
/memory:docs [path] [--tool <gemini|qwen|codex>] [--mode <full|partial>] [--cli-execute]
```

- **path**: Target directory (default: current directory)
  - Specifies the directory to generate documentation for

- **--mode**: Documentation generation mode (default: full)
  - `full`: Complete documentation (modules + project README + ARCHITECTURE + EXAMPLES)
    - Level 1: Module tree documentation
    - Level 2: Project README.md
    - Level 3: ARCHITECTURE.md + EXAMPLES.md + HTTP API (optional)
  - `partial`: Module documentation only
    - Level 1: Module tree documentation (API.md + README.md)
    - Skips project-level documentation

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

- **--cli-execute**: Enable CLI-based documentation generation (optional)
  - When enabled: CLI generates docs with MODE=write in implementation_approach, agent executes CLI commands
  - When disabled (default): CLI analyzes with MODE=analysis in pre_analysis, agent generates documentation content

## Planning Workflow

### Phase 1: Initialize Session

#### Step 1: Get Target Path and Project Name
```bash
# Get current directory as target path
bash(pwd)

# Get project name from current directory
bash(basename "$(pwd)")

# Get project root from git
bash(git rev-parse --show-toplevel 2>/dev/null || pwd)

# Generate timestamp for session ID
bash(date +%Y%m%d-%H%M%S)
```

**Output**:
- `target_path`: `/d/Claude_dms3`
- `project_name`: `Claude_dms3`
- `project_root`: `/d/Claude_dms3`
- `timestamp`: `20240120-143022`

#### Step 2: Create Session Structure
```bash
# Create session directories (replace timestamp with actual value)
bash(mkdir -p .workflow/WFS-docs-20240120-143022/.task)
bash(mkdir -p .workflow/WFS-docs-20240120-143022/.process)
bash(mkdir -p .workflow/WFS-docs-20240120-143022/.summaries)

# Mark session as active
bash(touch .workflow/.active-WFS-docs-20240120-143022)
```

#### Step 3: Create Workflow Session Metadata
```bash
# Create workflow-session.json in session root (replace values with actual data)
bash(echo '{"session_id":"WFS-docs-20240120-143022","project":"Claude_dms3 documentation","status":"planning","timestamp":"2024-01-20T14:30:22+08:00","path":".","target_path":"/d/Claude_dms3","project_root":"/d/Claude_dms3","project_name":"Claude_dms3","mode":"full","tool":"gemini","cli_execute":false}' | jq '.' > .workflow/WFS-docs-20240120-143022/workflow-session.json)
```

**Output**:
```
✓ Session initialized: WFS-docs-20240120-143022
✓ Target: /d/Claude_dms3
✓ Mode: full
✓ Tool: gemini, CLI execute: false
```

### Phase 2: Analyze Structure

**Smart filter**: Auto-detect and skip tests/build/config/vendor based on project tech stack (Node.js/Python/Go/Rust/etc).

#### Step 1: Discover and Classify Folders
```bash
# Run analysis pipeline (module discovery + folder classification + smart filtering)
bash(~/.claude/scripts/get_modules_by_depth.sh | ~/.claude/scripts/classify-folders.sh > .workflow/WFS-docs-20240120-143022/.process/folder-analysis.txt)
```

**Output Sample** (folder-analysis.txt):
```
./src/modules/auth|code|code:5|dirs:2
./src/modules/api|code|code:3|dirs:0
./src/utils|navigation|code:0|dirs:4
```

**Auto-skipped**:
- Tests: `**/test/**`, `**/*.test.*`, `**/__tests__/**`
- Build: `**/node_modules/**`, `**/dist/**`, `**/build/**`
- Config: Root-level config files (package.json, tsconfig.json, etc)
- Vendor: Language-specific dependency directories

#### Step 2: Extract Top-Level Directories
```bash
# Extract first path component from each line
bash(cat .workflow/WFS-docs-20240120-143022/.process/folder-analysis.txt | cut -d'|' -f1 | sed 's|^\./||' | grep -v '^$' > .workflow/WFS-docs-20240120-143022/.process/all-paths.txt)

# Get first two path levels (e.g., src/modules)
bash(cat .workflow/WFS-docs-20240120-143022/.process/all-paths.txt | cut -d'/' -f1-2 | sort -u > .workflow/WFS-docs-20240120-143022/.process/top-level-dirs.txt)
```

**Output** (top-level-dirs.txt):
```
src/modules
src/utils
lib/core
```

#### Step 3: Load All Existing Documentation (One-time Read)
```bash
# Read project name and load all existing module docs at once
bash(
  project_name=$(jq -r '.project_name' .workflow/WFS-docs-20240120-143022/workflow-session.json)
  find .workflow/docs/$project_name -type f -name '*.md' ! -path '*/README.md' ! -path '*/ARCHITECTURE.md' ! -path '*/EXAMPLES.md' ! -path '*/api/*' 2>/dev/null | xargs cat > .workflow/WFS-docs-20240120-143022/.process/all-existing-module-docs.txt 2>/dev/null || echo "No existing docs" > .workflow/WFS-docs-20240120-143022/.process/all-existing-module-docs.txt
)
```

#### Step 4: Unified Module Analysis (CLI - One-time Call)
```bash
# Unified analysis for all modules using configured CLI tool
bash(
  tool=$(jq -r '.tool' .workflow/WFS-docs-20240120-143022/workflow-session.json)
  $tool -p "
PURPOSE: Analyze all module structures for documentation planning
TASK:
• Parse folder-analysis.txt to identify all modules
• For each module, generate documentation outline
• Output structured analysis for all modules
MODE: analysis
CONTEXT: @.workflow/WFS-docs-20240120-143022/.process/folder-analysis.txt @.workflow/WFS-docs-20240120-143022/.process/all-existing-module-docs.txt
EXPECTED: Structured analysis with module paths and outlines
RULES: Output format: MODULE_PATH|outline_summary, one per line
" > .workflow/WFS-docs-20240120-143022/.process/unified-module-analysis.txt
)
```

**Result**: Generates `unified-module-analysis.txt` with format: `MODULE_PATH|outline_summary`

#### Step 5: Store Analysis Statistics
```bash
# Calculate and store statistics to workflow-session.json
bash(
  total=$(wc -l < .workflow/WFS-docs-20240120-143022/.process/folder-analysis.txt)
  code_count=$(grep '|code|' .workflow/WFS-docs-20240120-143022/.process/folder-analysis.txt | wc -l)
  nav_count=$(grep '|navigation|' .workflow/WFS-docs-20240120-143022/.process/folder-analysis.txt | wc -l)
  top_dirs=$(wc -l < .workflow/WFS-docs-20240120-143022/.process/top-level-dirs.txt)

  jq ". + {analysis: {total: \"$total\", code: \"$code_count\", navigation: \"$nav_count\", top_level: \"$top_dirs\"}}" .workflow/WFS-docs-20240120-143022/workflow-session.json > .workflow/WFS-docs-20240120-143022/workflow-session.json.tmp && mv .workflow/WFS-docs-20240120-143022/workflow-session.json.tmp .workflow/WFS-docs-20240120-143022/workflow-session.json
)
```

### Phase 3: Detect Update Mode

#### Step 1: Get Project Name from Workflow Session
```bash
# Read project name from workflow-session.json
bash(jq -r '.project_name' .workflow/WFS-docs-20240120-143022/workflow-session.json)
```

**Output**: `Claude_dms3`

#### Step 2: Count Existing Documentation
```bash
# Count existing docs (replace project_name with actual value)
bash(find .workflow/docs/Claude_dms3 -name "*.md" 2>/dev/null | wc -l || echo 0)
```

**Output**: `5` (existing docs) or `0` (no docs)

#### Step 3: List Existing Documentation Files
```bash
# List existing docs to file (replace project_name and session)
bash(find .workflow/docs/Claude_dms3 -name "*.md" 2>/dev/null > .workflow/WFS-docs-20240120-143022/.process/existing-docs.txt || touch .workflow/WFS-docs-20240120-143022/.process/existing-docs.txt)

# Display existing docs
bash(cat .workflow/WFS-docs-20240120-143022/.process/existing-docs.txt)
```

**Output** (existing-docs.txt):
```
.workflow/docs/Claude_dms3/src/modules/auth/API.md
.workflow/docs/Claude_dms3/src/modules/auth/README.md
.workflow/docs/Claude_dms3/lib/core/README.md
.workflow/docs/Claude_dms3/README.md
```

#### Step 4: Update Workflow Session with Update Status
```bash
# If existing_count > 0, update with "update" mode (replace session and count)
bash(jq '. + {update_mode: "update", existing_docs: 5}' .workflow/WFS-docs-20240120-143022/workflow-session.json > .workflow/WFS-docs-20240120-143022/workflow-session.json.tmp && mv .workflow/WFS-docs-20240120-143022/workflow-session.json.tmp .workflow/WFS-docs-20240120-143022/workflow-session.json)

# Or if existing_count = 0, use "create" mode
bash(jq '. + {update_mode: "create", existing_docs: 0}' .workflow/WFS-docs-20240120-143022/workflow-session.json > .workflow/WFS-docs-20240120-143022/workflow-session.json.tmp && mv .workflow/WFS-docs-20240120-143022/workflow-session.json.tmp .workflow/WFS-docs-20240120-143022/workflow-session.json)
```

#### Step 5: Display Strategy Summary
```bash
# Read session metadata
bash(jq -r '.mode' .workflow/WFS-docs-20240120-143022/workflow-session.json)
bash(jq -r '.update_mode' .workflow/WFS-docs-20240120-143022/workflow-session.json)
bash(jq -r '.existing_docs' .workflow/WFS-docs-20240120-143022/workflow-session.json)
bash(jq -r '.tool' .workflow/WFS-docs-20240120-143022/workflow-session.json)
bash(jq -r '.cli_execute' .workflow/WFS-docs-20240120-143022/workflow-session.json)
bash(jq -r '.target_path' .workflow/WFS-docs-20240120-143022/workflow-session.json)
```

### Phase 4: Decompose Tasks

#### Task Hierarchy

**Dynamic Task Generation** (based on directory count):

**Small Projects (≤3 directories)**:
```
Level 1: Module Trees (single task, all directories)
  └─ IMPL-001: Document Module Trees (all directories)

Level 2: Project README (mode=full only, depends on IMPL-001)
  └─ IMPL-002: Generate Project README

Level 3: Architecture & Examples (mode=full only, depends on IMPL-002)
  ├─ IMPL-003: Generate ARCHITECTURE.md + EXAMPLES.md
  └─ IMPL-004: Generate HTTP API (optional)
```

**Medium/Large Projects (≥4 directories, Example: 7 directories)**:
```
Level 1: Module Trees (parallel tasks, grouped by 2 directories)
  ├─ IMPL-001: Document Module Trees Group 1 (dirs 1-2)
  ├─ IMPL-002: Document Module Trees Group 2 (dirs 3-4)
  ├─ IMPL-003: Document Module Trees Group 3 (dirs 5-6)
  └─ IMPL-004: Document Module Trees Group 4 (dir 7)

Level 2: Project README (mode=full only, depends on all Level 1)
  └─ IMPL-005: Generate Project README

Level 3: Architecture & Examples (mode=full only, depends on Level 2)
  ├─ IMPL-006: Generate ARCHITECTURE.md + EXAMPLES.md
  └─ IMPL-007: Generate HTTP API (optional)
```

**Benefits**:
- ✅ **Parallel Execution**: Level 1 tasks run concurrently
- ✅ **Failure Isolation**: Single group failure doesn't block others
- ✅ **Progress Visibility**: Track each group independently
- ✅ **Load Balancing**: Max 2 directories per task (≤5 docs)

#### Step 1: Read Top-Level Directories
```bash
# Read top-level directories list
bash(cat .workflow/WFS-docs-20240120-143022/.process/top-level-dirs.txt)
```

**Output**:
```
src/modules
src/utils
lib
```

#### Step 2: Count Directories and Determine Grouping Strategy
```bash
# Count directories to determine grouping strategy
bash(wc -l < .workflow/WFS-docs-20240120-143022/.process/top-level-dirs.txt)
```

**Output**: `7` directories

**Grouping Rules** (max 5 docs/task, assumes 2 docs/directory average):
- **≤3 directories**: Single task (IMPL-001 only)
- **≥4 directories**: Group every 2 directories per task (max 4 docs/task)

**Example Grouping for 7 directories**:
- IMPL-001: Directories 1-2 (4 docs)
- IMPL-002: Directories 3-4 (4 docs)
- IMPL-003: Directories 5-6 (4 docs)
- IMPL-004: Directory 7 (2 docs)

#### Step 3: Create Directory Groups
```bash
# Create groups based on directory count
bash(
  dir_count=$(wc -l < .workflow/WFS-docs-20240120-143022/.process/top-level-dirs.txt)

  if [ $dir_count -le 3 ]; then
    # Single group: all directories
    cat .workflow/WFS-docs-20240120-143022/.process/top-level-dirs.txt > .workflow/WFS-docs-20240120-143022/.process/group-001.txt
    echo "1" > .workflow/WFS-docs-20240120-143022/.process/group-count.txt
  else
    # Multiple groups: 2 directories per group
    split -l 2 -d -a 3 .workflow/WFS-docs-20240120-143022/.process/top-level-dirs.txt .workflow/WFS-docs-20240120-143022/.process/group-

    # Rename split files to group-001.txt, group-002.txt, etc.
    for file in .workflow/WFS-docs-20240120-143022/.process/group-[0-9][0-9][0-9]; do
      mv "$file" "$file.txt"
    done

    # Count groups
    ls .workflow/WFS-docs-20240120-143022/.process/group-*.txt 2>/dev/null | wc -l > .workflow/WFS-docs-20240120-143022/.process/group-count.txt
  fi

  # Display group count
  cat .workflow/WFS-docs-20240120-143022/.process/group-count.txt
)
```

**Output**: `4` (number of Level 1 tasks to generate)

**Generated Files**:
- `.process/group-001.txt`: First 2 directories
- `.process/group-002.txt`: Next 2 directories
- `.process/group-003.txt`: Next 2 directories
- `.process/group-004.txt`: Remaining directories
- `.process/group-count.txt`: Total group count

#### Step 4: Check Documentation Mode
```bash
# Check if full or partial mode
bash(jq -r '.mode' .workflow/WFS-docs-20240120-143022/workflow-session.json)
```

**Output**: `full` or `partial`

#### Step 5: Check for HTTP API Endpoints (Optional)
```bash
# Search for API endpoint patterns
bash(grep -r "router\.|@Get\|@Post" src/ 2>/dev/null && echo "API_FOUND" || echo "NO_API")
```

**Output**: `API_FOUND` or `NO_API`

**Task Generation Summary** (Example: 7 directories):
- **Level 1 (Module Trees)**: IMPL-001 to IMPL-004 (4 tasks, grouped by 2 directories)
- **Partial mode**: Generate only Level 1 tasks
- **Full mode without API**: Level 1 tasks + IMPL-005 (README) + IMPL-006 (ARCHITECTURE+EXAMPLES)
- **Full mode with API**: Level 1 tasks + IMPL-005 (README) + IMPL-006 (ARCHITECTURE+EXAMPLES) + IMPL-007 (HTTP API)

**Task ID Calculation**:
```bash
group_count=$(cat .workflow/WFS-docs-20240120-143022/.process/group-count.txt)
readme_id=$((group_count + 1))        # Example: IMPL-005
arch_id=$((group_count + 2))          # Example: IMPL-006
api_id=$((group_count + 3))           # Example: IMPL-007
```

### Phase 5: Generate Task JSONs

#### Step 1: Read Configuration Values
```bash
# Read tool selection
bash(jq -r '.tool' .workflow/WFS-docs-20240120-143022/workflow-session.json)

# Read cli_execute flag
bash(jq -r '.cli_execute' .workflow/WFS-docs-20240120-143022/workflow-session.json)

# Read mode
bash(jq -r '.mode' .workflow/WFS-docs-20240120-143022/workflow-session.json)
```

**Output**:
- `tool`: `gemini`
- `cli_execute`: `false`
- `mode`: `full`

#### Step 2: Determine CLI Strategy

**If cli_execute = false (Agent Mode)**:
- MODE: `analysis`
- Placement: `pre_analysis`
- Approval flag: (none)
- Command pattern: `cd dir && gemini -p "..."`
- Agent role: Generate documentation content in implementation_approach

**If cli_execute = true (CLI Mode)**:
- MODE: `write`
- Placement: `implementation_approach`
- Approval flag: `--approval-mode yolo`
- Command pattern: `cd dir && gemini --approval-mode yolo -p "..."`
- Agent role: Execute CLI commands, validate output

**If tool = codex**:
- Command pattern: `codex -C dir --full-auto exec "..." --skip-git-repo-check -s danger-full-access`

#### Step 3: Generate Level 1 Task JSON Files (Loop)

**Process**: Generate one task JSON per directory group.

```bash
# Read group count
bash(cat .workflow/WFS-docs-20240120-143022/.process/group-count.txt)
```

**Output**: `4` (generates IMPL-001, IMPL-002, IMPL-003, IMPL-004)

**Generation Loop** (pseudo-code):
```javascript
group_count = read(".process/group-count.txt")

for (i = 1; i <= group_count; i++) {
  group_id = sprintf("IMPL-%03d", i)
  group_file = sprintf(".process/group-%03d.txt", i)

  // Read directories for this group
  directories = read(group_file)

  // Generate task JSON from template
  task = generate_level1_task({
    id: group_id,
    title: `Document Module Trees Group ${i}`,
    directories: directories,
    group_number: i,
    total_groups: group_count
  })

  // Write to .task/ directory
  write(`.task/${group_id}.json`, task)
}
```

**Generated Files**:
- `.task/IMPL-001.json` - Group 1 (directories 1-2)
- `.task/IMPL-002.json` - Group 2 (directories 3-4)
- `.task/IMPL-003.json` - Group 3 (directories 5-6)
- `.task/IMPL-004.json` - Group 4 (directory 7)

#### Step 4: Generate Level 2/3 Task JSON Files (Conditional)

**Process**: Generate README, ARCHITECTURE, and HTTP API tasks based on mode.

```bash
# Calculate task IDs
bash(
  group_count=$(cat .workflow/WFS-docs-20240120-143022/.process/group-count.txt)
  readme_id=$(printf "IMPL-%03d" $((group_count + 1)))
  arch_id=$(printf "IMPL-%03d" $((group_count + 2)))
  api_id=$(printf "IMPL-%03d" $((group_count + 3)))

  echo "README Task ID: $readme_id"
  echo "ARCHITECTURE Task ID: $arch_id"
  echo "HTTP API Task ID: $api_id"
)
```

**Output**:
- README Task ID: `IMPL-005`
- ARCHITECTURE Task ID: `IMPL-006`
- HTTP API Task ID: `IMPL-007`

**Conditional Generation**:
- **Partial mode**: No Level 2/3 tasks
- **Full mode**: Generate README + ARCHITECTURE tasks
- **Full mode + API detected**: Generate README + ARCHITECTURE + HTTP API tasks

**Generated Files** (full mode with API):
- `.task/IMPL-005.json` - Project README (depends on IMPL-001 to IMPL-004)
- `.task/IMPL-006.json` - ARCHITECTURE + EXAMPLES (depends on IMPL-005)
- `.task/IMPL-007.json` - HTTP API documentation (depends on IMPL-006)

## Task Templates

### Level 1: Module Trees Group Task

**Path Mapping**:
- Project: `{project_name}` (extracted from target_path)
- Sources: Subset of directories from `group-${group_number}.txt`
- Output: `.workflow/docs/{project_name}/` (mirrored structure)

**Execution Model**: Each task processes assigned directory group (max 2 directories) using pre-analyzed data from Phase 2.

**Agent Mode (cli_execute=false)**:
```json
{
  "id": "IMPL-${group_number}",
  "title": "Document Module Trees Group ${group_number}",
  "status": "pending",

## Execution Commands

```bash
# Execute entire workflow (auto-discovers active session)
/workflow:execute

# Or specify session
/workflow:execute --resume-session="WFS-docs-yyyymmdd-hhmmss"

# Individual task execution (if needed)
/task:execute IMPL-001
```

## Simple Bash Commands

### Session Management
```bash
# Generate timestamp
bash(date +%Y%m%d-%H%M%S)

# Create session directories (replace timestamp)
bash(mkdir -p .workflow/WFS-docs-20240120-143022/.task)
bash(mkdir -p .workflow/WFS-docs-20240120-143022/.process)
bash(mkdir -p .workflow/WFS-docs-20240120-143022/.summaries)

# Mark as active
bash(touch .workflow/.active-WFS-docs-20240120-143022)

# Get project name
bash(basename "$(pwd)")

# Create workflow-session.json (replace values)
bash(echo '{"session_id":"WFS-docs-20240120-143022","project":"project documentation","status":"planning","timestamp":"2024-01-20T14:30:22+08:00","path":".","target_path":"/d/project","project_root":"/d/project","project_name":"project","mode":"full","tool":"gemini","cli_execute":false}' | jq '.' > .workflow/WFS-docs-20240120-143022/workflow-session.json)

# Read workflow session metadata
bash(cat .workflow/WFS-docs-20240120-143022/workflow-session.json)

# Extract session values
bash(jq -r '.tool' .workflow/WFS-docs-20240120-143022/workflow-session.json)
bash(jq -r '.mode' .workflow/WFS-docs-20240120-143022/workflow-session.json)
bash(jq -r '.project_name' .workflow/WFS-docs-20240120-143022/workflow-session.json)

# List session tasks
bash(ls .workflow/WFS-docs-20240120-143022/.task/*.json)
```

### Analysis Commands
```bash
# Discover and classify folders
bash(~/.claude/scripts/get_modules_by_depth.sh | ~/.claude/scripts/classify-folders.sh > .workflow/WFS-docs-20240120-143022/.process/folder-analysis.txt)

# Count existing docs (replace project_name)
bash(find .workflow/docs/my_project -name "*.md" 2>/dev/null | wc -l || echo 0)

# List existing documentation (replace project_name)
bash(find .workflow/docs/my_project -name "*.md" 2>/dev/null || echo "No docs found")

# Check if docs directory exists
bash(test -d .workflow/docs/my_project && echo "exists" || echo "not exists")
```

## Template Reference

**Available Templates**:
- `api.txt`: Unified template for Code API (Part A) and HTTP API (Part B)
- `module-readme.txt`: Module purpose, usage, dependencies
- `folder-navigation.txt`: Navigation README for folders with subdirectories
- `project-readme.txt`: Project overview, getting started, module navigation

## Execution Mode Summary

| Mode | CLI Placement | CLI MODE | Agent Role |
|------|---------------|----------|------------|
| **Agent Mode (default)** | pre_analysis (Phase 2) | analysis | Generates documentation files based on pre-analyzed data |
| **CLI Mode (--cli-execute)** | implementation_approach | write | Executes CLI commands to generate docs, validates output |

**Execution Flow**:
