## Quick Start

### 1. Extract Test Examples (C3.2)

First, extract workflow examples from your test files:

```bash
# Extract test examples including workflows
skill-seekers analyze tests/ \
  --extract-test-examples \
  --output output/codebase/

# Or use standalone tool
skill-seekers-extract-test-examples tests/ \
  --output output/codebase/test_examples/
```

### 2. Build How-To Guides (C3.3)

Generate guides from extracted workflow examples:

```bash
# Build guides from extracted examples
skill-seekers-how-to-guides \
  output/codebase/test_examples/test_examples.json \
  --output output/codebase/tutorials/

# Choose grouping strategy
skill-seekers-how-to-guides examples.json \
  --group-by ai-tutorial-group   # AI-based (default)
  --group-by file-path            # Group by test file
  --group-by test-name            # Group by test name patterns
  --group-by complexity           # Group by difficulty level
```

### 3. Automatic Integration (Recommended)

Enable guide generation during codebase analysis:

```bash
# Automatic pipeline: extract tests → build guides
skill-seekers analyze tests/ \
  --extract-test-examples \
  --build-how-to-guides \
  --output output/codebase/

# Skip guide generation
skill-seekers analyze tests/ \
  --skip-how-to-guides
```

## AI Enhancement (NEW!)

Transform basic guides (⭐⭐) into professional tutorials (⭐⭐⭐⭐⭐) with comprehensive AI-powered improvements.

### What Gets Enhanced

The AI Enhancement system provides **5 automatic improvements** that dramatically increase guide quality:

#### 1. Step Descriptions (⭐⭐⭐)
Natural language explanations for each step - not just syntax!

**Before:**
```markdown
### Step 1
```python
scraper.scrape(url)
```
**After:**
```markdown
### Step 1: Initialize the scraper
```python
scraper.scrape(url)
```

**Explanation:** Initialize the scraper with the target URL. This configures the HTTP client, sets up request headers, and prepares the URL queue for BFS traversal. The scraper will respect rate limits and follow the URL patterns defined in your configuration.

**Common Variations:**
- Use `AsyncDocumentationScraper()` for concurrent scraping (3-5x faster)
- Pass custom headers for authentication: `scraper.scrape(url, headers={'Authorization': 'Bearer token'})`
```

#### 2. Troubleshooting Solutions (⭐⭐⭐)
Diagnostic flows + solutions for common errors

**Before:**
```markdown
## Troubleshooting
- ImportError
- Connection timeout
```

**After:**
```markdown
## Troubleshooting

### ImportError: No module named 'requests'

**Symptoms:**
- Import statement fails immediately
- Module not found error in stack trace
- Script exits before any execution

**Diagnosis:**
1. Check if package is installed: `pip list | grep requests`
2. Verify virtual environment is active: `which python`
3. Confirm Python version compatibility: `python --version`

**Solution:**
```bash
# Activate virtual environment first (if using one)
source venv/bin/activate

# Install the missing package
pip install requests

# Verify installation
python -c "import requests; print(requests.__version__)"
```

### Connection Timeout

**Symptoms:**
- Scraper hangs for 30-60 seconds
- TimeoutError or ConnectTimeout exception
- No response from target server

**Diagnosis:**
1. Check internet connection: `ping example.com`
2. Verify URL is accessible: `curl -I https://docs.example.com`
3. Check firewall/proxy settings

**Solution:**
```python
# Increase timeout in scraper configuration
config = {
    'timeout': 60,  # Increase from default 30 seconds
    'retry_attempts': 3,
    'retry_delay': 5
}
scraper = DocumentationScraper(config)
```
```

#### 3. Prerequisites Explanations (⭐⭐)
Why each prerequisite is needed + setup instructions

**Before:**
```markdown
## Prerequisites
- requests
- beautifulsoup4
```

**After:**
```markdown
## Prerequisites

### requests
**Why needed:** HTTP client library for fetching web pages over HTTP/HTTPS. Handles connections, headers, redirects, and response parsing.

**Setup:**
```bash
pip install requests
```

**Version recommendation:** >= 2.28.0 (for improved SSL support)

### beautifulsoup4
**Why needed:** HTML/XML parser for extracting content from web pages. Provides intuitive API for navigating and searching the document tree.

### How to Use AI Enhancement

#### Method 1: Automatic (Recommended)

AI enhancement happens automatically with AUTO mode detection:

```bash
# Auto-detects best mode (API if key set, else LOCAL)
skill-seekers analyze tests/ \
  --extract-test-examples \
  --build-how-to-guides \
  --ai-mode auto
```

#### Method 2: API Mode

Use Claude API directly (requires ANTHROPIC_API_KEY):

```bash
# Set API key
export ANTHROPIC_API_KEY=sk-ant-...

# Enable API mode
skill-seekers analyze tests/ \
  --build-how-to-guides \
  --ai-mode api
```

**Characteristics:**
- Fast and efficient
- Perfect for automation/CI
- Cost: ~$0.15-$0.30 per guide
- Processes multiple guides in parallel

#### Method 3: LOCAL Mode

Use Claude Code CLI (no API key needed):

```bash
# Uses your Claude Code Max plan (FREE!)
skill-seekers analyze tests/ \
  --build-how-to-guides \
  --ai-mode local
```

**Characteristics:**
- Uses existing Claude Code Max plan
- Opens in terminal for 30-60 seconds
- Perfect for local development
- No API costs!
- Same quality as API mode

#### Method 4: Disable AI Enhancement

Generate basic guides without AI:

```bash
# Faster, but basic quality
skill-seekers analyze tests/ \
  --build-how-to-guides \
  --ai-mode none
```

### API vs LOCAL Mode Comparison

| Feature | API Mode | LOCAL Mode |
|---------|----------|------------|
| **Requirements** | ANTHROPIC_API_KEY | Claude Code CLI installed |
| **Cost** | ~$0.15-$0.30 per guide | FREE (uses Claude Code Max) |
| **Speed** | Fast (parallel processing) | Moderate (30-60s per guide) |
| **Quality** | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐⭐ (same quality) |
| **Use Case** | Automation, CI/CD, batch processing | Local development, testing |
| **Setup** | `export ANTHROPIC_API_KEY=...` | Claude Code Max subscription |
| **Parallel Processing** | ✅ Yes (multiple guides at once) | ❌ No (sequential) |
| **Offline** | ❌ Requires internet | ❌ Requires internet |

### Example Workflow

**Complete workflow with AI enhancement:**

```bash
# 1. Extract test examples from your codebase
skill-seekers analyze tests/ \
  --extract-test-examples \
  --output output/codebase/

# 2. Build enhanced guides (AUTO mode)
skill-seekers-how-to-guides \
  output/codebase/test_examples/test_examples.json \
  --group-by ai-tutorial-group \
  --ai-mode auto \
  --output output/codebase/tutorials/

# 3. Review generated guides
cat output/codebase/tutorials/index.md
cat output/codebase/tutorials/user_management.md

# 4. Verify enhancements applied
grep -A 5 "## Troubleshooting" output/codebase/tutorials/*.md
```

### Troubleshooting AI Enhancement

**Issue: API mode fails with authentication error**
```bash
# Check API key is set correctly
echo $ANTHROPIC_API_KEY

# Verify key format (should start with sk-ant-)
# Set key properly
export ANTHROPIC_API_KEY=sk-ant-your-key-here
```

**Issue: LOCAL mode doesn't open Claude Code**
```bash
# Verify Claude Code is installed
which claude

# If not found, install Claude Code CLI
# See: https://claude.com/code
```

**Issue: Enhancement takes too long**
```bash
# Switch to API mode for faster processing
skill-seekers analyze tests/ \
  --build-how-to-guides \
  --ai-mode api  # Much faster than LOCAL

# Or disable enhancement for testing
--ai-mode none
```

**Issue: Want to skip enhancement for specific guides**
```bash
# Generate basic guides first
skill-seekers-how-to-guides examples.json --ai-mode none

# Then enhance only specific guides manually
skill-seekers-enhance output/codebase/tutorials/user_management.md
```

## Grouping Strategies

### 1. AI Tutorial Group (Default - Recommended)

Uses AI analysis from C3.6 enhancement to intelligently group related workflows.

**Behavior:**
- Groups workflows by tutorial theme (e.g., "User Management", "Database Operations")
- Considers semantic similarity of test names and code
- Falls back to file-path grouping if AI data unavailable

**Best for:** Maximum quality, logical topic organization

```bash
skill-seekers-how-to-guides examples.json --group-by ai-tutorial-group
```

**Example Output:**
```
tutorials/
├── index.md
├── user-management.md          # User creation, updates, deletion
├── authentication-workflows.md # Login, logout, token management
├── database-operations.md      # CRUD operations, migrations
└── api-integration.md          # External API calls, webhooks
```

### 2. File Path Grouping

Groups workflows by test file location.

**Behavior:**
- One guide per test file
- Title derived from file name
- Preserves existing file organization

**Best for:** Small projects, file-based organization

```bash
skill-seekers-how-to-guides examples.json --group-by file-path
```

**Example Output:**
```
tutorials/
├── index.md
├── test-user.md              # All workflows from tests/test_user.py
├── test-auth.md              # All workflows from tests/test_auth.py
└── test-database.md          # All workflows from tests/test_database.py
```

### 3. Test Name Grouping

Groups workflows by test name prefixes.

**Behavior:**
- Identifies common prefixes (e.g., `test_user_*`, `test_admin_*`)
- Groups workflows with shared prefixes
- Falls back to individual guides

**Best for:** Consistent test naming conventions

```bash
skill-seekers-how-to-guides examples.json --group-by test-name
```

**Example Output:**
```
tutorials/
├── index.md
├── user-workflows.md         # test_user_create, test_user_update, test_user_delete
├── admin-workflows.md        # test_admin_create, test_admin_permissions
└── integration-workflows.md  # test_integration_api, test_integration_db
```

### 4. Complexity Grouping

Groups workflows by difficulty level.

**Behavior:**
- Analyzes code complexity
- Groups by beginner/intermediate/advanced
- Sorted within groups by topic

**Best for:** Educational content, progressive learning paths

```bash
skill-seekers-how-to-guides examples.json --group-by complexity
```

**Example Output:**
```
tutorials/
├── index.md
├── beginner-guides.md        # Simple workflows, 2-4 steps
├── intermediate-guides.md    # Moderate complexity, 5-7 steps
└── advanced-guides.md        # Complex workflows, 8+ steps, async, error handling
```

## Architecture

### Core Components

#### 1. WorkflowAnalyzer

Analyzes workflow examples to extract steps and metadata.

**Features:**
- Python AST-based step extraction
- Heuristic extraction for other languages
- Prerequisites detection (imports, fixtures)
- Verification point identification (assertions)
- Complexity scoring

**Example:**
```python
analyzer = WorkflowAnalyzer()
steps, metadata = analyzer.analyze_workflow(workflow_example)

# Returns:
# - steps: List[WorkflowStep]
# - metadata: Dict with complexity_level, prerequisites, etc.
```

#### 2. WorkflowGrouper

Groups related workflows into coherent guides.

**Strategies:**
- AI tutorial grouping (uses C3.6 analysis)
- File path grouping
- Test name pattern matching
- Complexity-based grouping

**Example:**
```python
grouper = WorkflowGrouper()
grouped = grouper.group_workflows(workflows, strategy='ai-tutorial-group')

# Returns: Dict[str, List[Dict]]
# Key: Guide title
# Value: List of related workflows
```

#### 3. GuideGenerator

Generates markdown guides from workflow data.

**Methods:**
- `generate_guide_markdown()` - Complete guide
- `generate_index()` - Guide catalog
- `_create_header()` - Title and metadata
- `_create_steps_section()` - Step-by-step instructions
- `_create_complete_example()` - Full working code

**Example:**
```python
generator = GuideGenerator()
markdown = generator.generate_guide_markdown(guide)
index = generator.generate_index(guides)
```

#### 4. HowToGuideBuilder

Main orchestrator coordinating all components.

**Workflow:**
1. Extract workflow examples from test data
2. Analyze each workflow (steps, metadata)
3. Group related workflows
4. Generate guides for each group
5. Create index and save files

**Example:**
```python
builder = HowToGuideBuilder(enhance_with_ai=True)
collection = builder.build_guides_from_examples(
    examples,
    grouping_strategy='ai-tutorial-group',
    output_dir=Path('tutorials/')
)
```

### Data Models

---

## Integration with Other Features

### C3.2 Test Example Extraction (Prerequisite)

How-to guides are built from workflow examples extracted by C3.2:

```bash
# Full pipeline
skill-seekers analyze tests/ \
  --extract-test-examples \
  --build-how-to-guides
```

**Data Flow:**
1. C3.2 extracts test examples (5 categories)
2. C3.3 filters for `workflow` category
3. Analyzes workflows and generates guides

### C3.6 AI Enhancement (Optional)

AI analysis enhances grouping and explanations:

```bash
# With AI enhancement (default)
skill-seekers-how-to-guides examples.json \
  --group-by ai-tutorial-group

# Without AI (faster, basic grouping)
skill-seekers-how-to-guides examples.json --no-ai
```

**AI Contributions:**
- Tutorial group assignment
- Enhanced step descriptions
- Better troubleshooting tips
- Use case identification

### Codebase Scraper Integration

Automatic guide generation during codebase analysis:

```bash
skill-seekers analyze /path/to/repo/ \
  --extract-test-examples \
  --build-how-to-guides \
  --output output/codebase/
```

**Output Structure:**
```
output/codebase/
├── api_reference/
├── dependencies/
├── patterns/
├── test_examples/
└── tutorials/          # How-to guides (C3.3)
    ├── index.md
    └── *.md
```

---

## Use Cases

### 1. Onboarding Documentation

Generate tutorials for new team members:

```bash
skill-seekers-how-to-guides tests/integration/test_examples.json \
  --group-by ai-tutorial-group \
  --output docs/tutorials/
```

**Result:** Comprehensive guides showing how to use your APIs/libraries based on real test code.

### 2. API Usage Examples

Extract usage patterns from test suites:

```bash
skill-seekers analyze tests/api/ \
  --extract-test-examples \
  --build-how-to-guides
```

**Result:** Step-by-step API integration guides derived from actual test workflows.

### 3. Educational Content

Create progressive learning paths:

```bash
skill-seekers-how-to-guides examples.json \
  --group-by complexity \
  --output learning-path/
```

**Result:** Beginner → Intermediate → Advanced progression of tutorials.

### 4. Migration Guides

Document workflows for version upgrades:

```bash
# Extract from old version tests
skill-seekers-extract-test-examples tests/ --output old-examples.json

# Extract from new version tests
skill-seekers-extract-test-examples tests/ --output new-examples.json

# Generate migration guides
skill-seekers-how-to-guides old-examples.json --output migration/old/
skill-seekers-how-to-guides new-examples.json --output migration/new/
```

**Result:** Side-by-side comparison of old vs new workflows.

---

## Quality Filtering

4. **Category:** Must be `workflow` type

### Complexity Calculation

Automatic difficulty assessment based on:

**Beginner:**
- 2-4 steps
- Simple operations
- No async/error handling
- Standard library only

**Intermediate:**
- 5-7 steps
- Moderate complexity
- Some error handling
- External libraries

**Advanced:**
- 8+ steps
- Complex logic
- Async/await patterns
- Error handling + edge cases
- Multiple dependencies

---

## Troubleshooting

### No Guides Generated

**Problem:** `build_guides_from_examples()` returns collection with 0 guides

**Solutions:**
1. Check input has workflow examples:
   ```bash
   # Verify workflow examples exist
   jq '.examples[] | select(.category == "workflow")' examples.json
   ```

2. Lower quality threshold:
   ```python
   builder = HowToGuideBuilder(min_confidence=0.4)  # Default: 0.5
   ```

3. Check test example extraction included workflows:
   ```bash
   skill-seekers-extract-test-examples tests/ --json
   # Look for "workflow" in categories
   ```

### Poor Guide Quality

**Problem:** Generated guides are incomplete or unclear

**Solutions:**
1. Enable AI enhancement:
   ```bash
   skill-seekers-how-to-guides examples.json  # AI enabled by default
   ```

2. Use better grouping strategy:
   ```bash
   # Try ai-tutorial-group instead of file-path
   skill-seekers-how-to-guides examples.json --group-by ai-tutorial-group
   ```

3. Improve source tests:
   - Add descriptive comments
   - Use clear variable names
   - Include assertions for verification

### Wrong Grouping

**Problem:** Workflows grouped incorrectly

**Solutions:**
1. Try different grouping strategy:
   ```bash
   # If ai-tutorial-group fails, try file-path
   skill-seekers-how-to-guides examples.json --group-by file-path
   ```

2. Organize test files better:
   - Group related tests in same file
   - Use consistent test naming (e.g., `test_user_*`)

3. Add tutorial_group hints (for AI grouping):
   ```python
   def test_user_creation():
       """
       Tutorial group: User Management
       Create a new user in the database
       """
   ```

### Missing Steps

**Problem:** Guide missing obvious steps from test

**Solutions:**
1. Check Python version compatibility:
   - Python AST extraction requires Python 3.10+
   - Use `--no-ai` if Python < 3.10

2. Verify test structure:
   ```python
   # Good: Clear sequential steps
   def test_workflow():
       step1 = action1()  # Separated
       step2 = action2()  # Separated
       assert step2 == expected

   # Bad: Chained operations (harder to extract)
   def test_workflow():
       assert action2(action1()) == expected
   ```

3. For non-Python tests:
   - Add comments to indicate steps
   - Use clear variable assignments
   - Separate operations with blank lines

## Limitations & Future Enhancements

### Current Limitations

1. **Language Support:**
   - Deep analysis: Python only (AST-based)
   - Other languages: Heuristic extraction (less precise)

2. **Complexity Detection:**
   - Basic heuristics (step count, keywords)
   - No semantic complexity analysis

3. **Prerequisite Detection:**
   - Import-based only
   - Doesn't detect runtime dependencies

4. **No Code Execution:**
   - Cannot verify steps actually work
   - Relies on test passing status

### Planned Enhancements (v2.7+)

- [ ] **Multi-language AST Support** (C3.8)
  - JavaScript/TypeScript via tree-sitter
  - Go via go/ast
  - Rust via syn

- [ ] **Interactive Guides** (C3.9)
  - Copy-to-clipboard buttons
  - Live code execution (via Jupyter)
  - Step-by-step navigator

- [ ] **Video Generation** (C3.10)
  - Animated step diagrams
  - Screen recordings from workflows
  - Voiceover explanations

- [ ] **Diagram Integration** (C3.11)
  - Workflow flowcharts (Mermaid)
  - Architecture diagrams
  - Data flow visualizations

## Examples

### Example 1: User Management Workflow

**Input (test file):**
```python
def test_user_creation_workflow():
    """Complete user creation and verification workflow"""
    # Setup database
    db = Database('test.db')

    # Create user
    user = User(name='Alice', email='alice@example.com')
    db.save(user)

    # Verify user exists
    saved_user = db.get_user('Alice')
    assert saved_user.email == 'alice@example.com'

    # Update user
    saved_user.email = 'alice@newemail.com'
    db.update(saved_user)

    # Verify update
    updated_user = db.get_user('Alice')
    assert updated_user.email == 'alice@newemail.com'
```

**Output Guide:**

```markdown
# How To: Create and Manage Users in Database

**Difficulty**: Beginner
**Estimated Time**: 15 minutes
**Tags**: user, database, crud

## Overview

This guide demonstrates a complete user management workflow including
creation, verification, and updates using a database.

## Prerequisites

- [ ] Database configured and accessible
- [ ] User model imported

**Required Modules:**
- `from myapp import Database, User`

## Step-by-Step Guide

### Step 1: Initialize database connection

```python
db = Database('test.db')
```

**Expected Result:** Database connection established

### Step 2: Create user object

```python
user = User(name='Alice', email='alice@example.com')
db.save(user)
```

**Expected Result:** User saved to database

**Verification:**
```python
saved_user = db.get_user('Alice')
assert saved_user.email == 'alice@example.com'
```

### Step 3: Update user information

```python
saved_user.email = 'alice@newemail.com'
db.update(saved_user)
```

**Expected Result:** User record updated

**Verification:**
```python
updated_user = db.get_user('Alice')
assert updated_user.email == 'alice@newemail.com'
```

### Example 2: API Integration

**Input:**
```python
def test_api_integration_workflow():
    """Test complete API integration flow"""
    # Authenticate
    client = APIClient(base_url='https://api.example.com')
    token = client.authenticate(username='admin', password='secret')

    # Make authenticated request
    response = client.get('/users', headers={'Authorization': f'Bearer {token}'})
    assert response.status_code == 200

    # Parse and validate response
    users = response.json()
    assert len(users) > 0
    assert 'id' in users[0]
    assert 'name' in users[0]
```

**Generated Guide:** Step-by-step authentication and API request guide with verification at each step.

## Performance

### Benchmark Results

**Test Set:** Skill_Seekers own test suite
- 54 test files
- 1,880+ total tests
- 50+ workflow examples

**Performance:**
| Operation | Time | Output |
|-----------|------|--------|
| Workflow extraction | 0.5s | 50 workflows |
| Step analysis (Python AST) | 1.2s | 250 steps |
| AI grouping | 0.8s | 8 groups |
| Markdown generation | 0.3s | 8 guides |
| **Total** | **2.8s** | **8 comprehensive guides** |

**Memory:** ~40 MB peak

### Optimization Tips

1. **Disable AI for speed:**
   ```bash
   skill-seekers-how-to-guides examples.json --no-ai  # 2x faster
   ```

2. **Use simpler grouping:**
   ```bash
   # file-path is faster than ai-tutorial-group
   skill-seekers-how-to-guides examples.json --group-by file-path
   ```

3. **Filter input examples:**
   ```bash
   # Only high-confidence workflows
   jq '.examples[] | select(.category == "workflow" and .confidence >= 0.8)' \
     examples.json > filtered.json
   ```
