## Core APIs

### 1. Documentation Scraping API

Extract content from documentation websites using BFS traversal and smart categorization.

#### Basic Usage

```python
from skill_seekers.cli.doc_scraper import scrape_all, build_skill
import json

# Load configuration
with open('configs/react.json', 'r') as f:
    config = json.load(f)

# Scrape documentation
pages = scrape_all(
    base_url=config['base_url'],
    selectors=config['selectors'],
    config=config,
    output_dir='output/react_data'
)

print(f"Scraped {len(pages)} pages")

# Build skill from scraped data
skill_path = build_skill(
    config_name='react',
    output_dir='output/react',
    data_dir='output/react_data'
)

print(f"Skill created at: {skill_path}")
```

#### Advanced Scraping Options

```python
from skill_seekers.cli.doc_scraper import scrape_all

# Custom scraping with advanced options
pages = scrape_all(
    base_url='https://docs.example.com',
    selectors={
        'main_content': 'article',
        'title': 'h1',
        'code_blocks': 'pre code'
    },
    config={
        'name': 'my-framework',
        'description': 'Custom framework documentation',
        'rate_limit': 0.5,  # 0.5 second delay between requests

## Performance Optimization

### Async Scraping

```python
from skill_seekers.cli.doc_scraper import scrape_all

# Enable async for 2-3x speed improvement
pages = scrape_all(
    base_url='https://docs.example.com',
    selectors={'main_content': 'article'},
    config={'name': 'example'},
    use_async=True  # 2-3x faster
)
```

### Caching and Rebuilding

```python
from skill_seekers.cli.doc_scraper import build_skill

# First scrape (slow - 15-45 minutes)
build_skill(config_name='react', output_dir='output/react')

# Rebuild without re-scraping (fast - <1 minute)
build_skill(
    config_name='react',
    output_dir='output/react',
    data_dir='output/react_data',
    skip_scrape=True  # Use cached data
)
```

### Batch Processing

```python
from concurrent.futures import ThreadPoolExecutor
from skill_seekers.cli.install_skill import install_skill

configs = ['react', 'vue', 'angular', 'svelte']

def install_config(config_name):
    return install_skill(
        config_name=config_name,
        target='markdown',
        enhance=False,
        upload=False,
        force=True
    )

# Process 4 configs in parallel
with ThreadPoolExecutor(max_workers=4) as executor:
    results = list(executor.map(install_config, configs))

for config, result in zip(configs, results):
    print(f"{config}: {result['success']}")
```

## Best Practices

### 1. **Use Configuration Files**
Store configs in version control for reproducibility:
```python
import json
with open('configs/my-framework.json') as f:
    config = json.load(f)
scrape_all(config=config)
```

### 2. **Enable Async for Large Sites**
```python
pages = scrape_all(base_url=url, config=config, use_async=True)
```

### 3. **Cache Scraped Data**
```python
# Scrape once
scrape_all(config=config, output_dir='output/data')

# Rebuild many times (fast!)
build_skill(config_name='framework', data_dir='output/data', skip_scrape=True)
```

### 4. **Use Platform Adaptors**
```python
# Good: Platform-agnostic
adaptor = get_adaptor(target_platform)
adaptor.package(skill_dir)

# Bad: Hardcoded for one platform
# create_zip_for_claude(skill_dir)
```

### 5. **Handle Errors Gracefully**
```python
try:
    result = install_skill(config_name='framework', target='claude')
except NetworkError:
