## API Integration

### Python Usage

```python
import os
from claude_suite import ClaudeClient, ModelType

# Initialize client
client = ClaudeClient(
    api_key=os.getenv("CLAUDE_API_KEY"),
    model=ModelType.OPUS_4_6
)

# Basic code generation
response = client.generate(
    prompt="Write a Python function to calculate Fibonacci numbers",
    max_tokens=2048,
    temperature=0.7
)

print(response.content)

# Advanced reasoning task
code_review = client.analyze_code(
    code="""
    def process_data(items):
        result = []
        for i in items:
            if i > 0:
                result.append(i * 2)
        return result
    """,
    task="Review this code for performance issues and suggest improvements"
)

print(code_review.suggestions)
```

### Advanced API Features

```python
from claude_suite import ClaudeClient, ConversationManager

client = ClaudeClient(api_key=os.getenv("CLAUDE_API_KEY"))

# Multi-turn conversation
conversation = ConversationManager(client)

# First message
response1 = conversation.send(
    "I need to design a REST API for a blog system"
)

# Follow-up in same context
response2 = conversation.send(
    "Now add authentication using JWT"
)

# Access full conversation history
history = conversation.get_history()
```

### JavaScript/Node.js Usage

```javascript
const { ClaudeClient, ModelType } = require('claude-suite');

// Initialize client
const client = new ClaudeClient({
  apiKey: process.env.CLAUDE_API_KEY,
  model: ModelType.OPUS_4_6
});

// Generate code
async function generateCode() {
  const response = await client.generate({
    prompt: 'Create a React component for user authentication',
    maxTokens: 2048,
    temperature: 0.7
  });
  
  console.log(response.content);
}

// Analyze architecture
async function analyzeArchitecture() {
  const analysis = await client.analyzeArchitecture({
    description: 'Microservices architecture with event-driven communication',
    requirements: [
      'High availability',
      'Scalability',
      'Data consistency'
    ]
  });
  
  console.log(analysis.recommendations);
}

generateCode();
```

## Configuration

### Config File Structure

Create `claude-config.json`:

```json
{
  "api": {
    "base_url": "https://api.anthropic.com/v1",
    "timeout": 30000,
    "retry_attempts": 3
  },
  "models": {
    "default": "claude-opus-4-6",
    "fallback": "claude-3-5-sonnet"
  },
  "generation": {
    "max_tokens": 4096,
    "temperature": 0.7,
    "top_p": 0.9
  },
  "prompts": {
    "template_dir": "./prompts",
    "use_artifacts": true
  }
}
```

### Loading Configuration

```python
from claude_suite import ClaudeClient, load_config

# Load from config file
config = load_config("claude-config.json")
client = ClaudeClient.from_config(config)

# Override specific settings
client.set_temperature(0.5)
client.set_max_tokens(8192)
```

## Prompt Templates & Artifacts

### Using Curated Prompts

```python
from claude_suite import PromptLibrary

library = PromptLibrary(template_dir="./prompts")

# Load pre-built prompt for code review
code_review_prompt = library.get("code-review-deep")

response = client.generate(
    prompt=code_review_prompt.format(
        code=your_code,
        language="python",
        focus="security and performance"
    )
)
```

### Custom Prompt Artifacts

```python
from claude_suite import ArtifactBuilder

# Create structured prompt with artifacts
artifact = ArtifactBuilder()
artifact.add_context("You are an expert systems architect")
artifact.add_constraint("Must follow microservices best practices")
artifact.add_example({
    "input": "User registration service",
    "output": "RESTful API with /register, /verify endpoints"
})

prompt = artifact.build()
response = client.generate(prompt=prompt)
```

## Common Patterns

### Pair Programming Assistant

```python
from claude_suite import PairProgrammer

programmer = PairProgrammer(
    client=client,
    language="python",
    style="functional"
)

# Implement feature with AI assistance
implementation = programmer.implement_feature(
    description="Add caching layer to API endpoints",
    existing_code=current_codebase,
    constraints=["Use Redis", "Implement TTL"]
)

print(implementation.code)
print(implementation.tests)
print(implementation.documentation)
```

### Bug Fixing Workflow

```python
from claude_suite import BugFixer

fixer = BugFixer(client=client)

# Analyze and fix bug
fix = fixer.analyze_and_fix(
    error_message="TypeError: 'NoneType' object is not subscriptable",
    stack_trace=stack_trace_text,
    source_code=buggy_code,
    context="Function should handle null values"
)

print(fix.explanation)
print(fix.fixed_code)
print(fix.test_cases)
```

### Batch Processing

```python
from claude_suite import BatchProcessor

processor = BatchProcessor(client=client)

# Process multiple tasks
tasks = [
    {"type": "refactor", "code": code1, "goal": "improve readability"},
    {"type": "optimize", "code": code2, "goal": "reduce complexity"},
    {"type": "document", "code": code3, "goal": "add docstrings"}
]

results = processor.process_batch(
    tasks=tasks,
    parallel=True,
    max_workers=3
)

for result in results:
    print(f"Task: {result.task_type}")
    print(f"Output: {result.output}")
```

## API Endpoints Reference

### Direct API Calls

```python
import requests
import os

api_key = os.getenv("CLAUDE_API_KEY")
headers = {
    "x-api-key": api_key,
    "anthropic-version": "2023-06-01",
    "content-type": "application/json"
}

# Messages API
response = requests.post(
    "https://api.anthropic.com/v1/messages",
    headers=headers,
    json={
        "model": "claude-opus-4-6",
        "max_tokens": 4096,
        "messages": [
            {
                "role": "user",
                "content": "Explain how to implement OAuth2 in Python"
            }
        ]
    }
)

data = response.json()
print(data["content"][0]["text"])
```

### Streaming Responses

```python
from claude_suite import ClaudeClient

client = ClaudeClient(api_key=os.getenv("CLAUDE_API_KEY"))

# Stream long responses
for chunk in client.stream(
    prompt="Write a comprehensive guide to async programming in Python",
    max_tokens=8192
):
    print(chunk.delta, end="", flush=True)
```

## Error Handling & Troubleshooting

### Common Issues

**Authentication Errors**
```python
from claude_suite import ClaudeClient, AuthenticationError

try:
    client = ClaudeClient(api_key=os.getenv("CLAUDE_API_KEY"))
    response = client.generate(prompt="Test")
except AuthenticationError as e:
    print(f"API key invalid or expired: {e}")
    print("Verify CLAUDE_API_KEY environment variable")
```

**Rate Limiting**
```python
from claude_suite import RateLimitError
import time

def safe_generate(client, prompt, max_retries=3):
    for attempt in range(max_retries):
        try:
            return client.generate(prompt=prompt)
        except RateLimitError as e:
            if attempt < max_retries - 1:
                wait_time = e.retry_after or (2 ** attempt)
                print(f"Rate limited. Waiting {wait_time}s...")
                time.sleep(wait_time)
            else:
                raise
```

**Token Limit Exceeded**
```python
from claude_suite import TokenLimitError

try:
    response = client.generate(
        prompt=very_long_prompt,
        max_tokens=100000  # Too large
    )
except TokenLimitError as e:
    print(f"Token limit exceeded: {e.limit}")
    # Split into smaller chunks
    chunks = split_prompt(very_long_prompt, chunk_size=4096)
    results = [client.generate(prompt=chunk) for chunk in chunks]
```

### Debugging Mode

```python
from claude_suite import ClaudeClient

client = ClaudeClient(
    api_key=os.getenv("CLAUDE_API_KEY"),
    debug=True,
    log_file="claude-debug.log"
)

# All API calls will be logged
response = client.generate(prompt="Test debugging")
```

## Best Practices

1. **Always use environment variables for API keys**
   ```bash
   export CLAUDE_API_KEY=sk-ant-...
   ```

2. **Implement proper error handling**
   - Catch specific exceptions
   - Implement retry logic for transient errors
   - Log errors for debugging

3. **Optimize token usage**
   - Use appropriate `max_tokens` values
   - Leverage streaming for long responses
   - Cache repeated queries

4. **Use appropriate models**
   - Claude 4.6 Opus: Complex reasoning, architecture design
   - Claude 3.5 Sonnet: Faster responses, routine tasks

5. **Version control prompts**
   - Store prompt templates separately
   - Track changes to prompt engineering
   - A/B test different approaches
