## Quick Reference

### Basic API Usage

```python
import anthropic

client = anthropic.Anthropic(api_key="your-api-key")

# Simple message
response = client.messages.create(
    model="claude-3-5-sonnet-20241022",
    max_tokens=1024,
    messages=[{
        "role": "user",
        "content": "Hello, Claude!"
    }]
)
```

### Tool Use (Function Calling)

```python
# Define a tool
tools = [{
    "name": "get_weather",
    "description": "Get current weather for a location",
    "input_schema": {
        "type": "object",
        "properties": {
            "location": {"type": "string", "description": "City name"}
        },
        "required": ["location"]
    }
}]

# Use the tool
response = client.messages.create(
    model="claude-3-5-sonnet-20241022",
    max_tokens=1024,
    tools=tools,
    messages=[{"role": "user", "content": "What's the weather in San Francisco?"}]
)
```

### Vision (Image Analysis)

```python
# Analyze an image
response = client.messages.create(
    model="claude-3-5-sonnet-20241022",
    max_tokens=1024,
    messages=[{
        "role": "user",
        "content": [
            {
                "type": "image",
                "source": {
                    "type": "base64",
                    "media_type": "image/jpeg",
                    "data": base64_image
                }
            },
            {"type": "text", "text": "Describe this image"}
        ]
    }]
)
```

### Prompt Caching

```python
# Use prompt caching for efficiency
response = client.messages.create(
    model="claude-3-5-sonnet-20241022",
    max_tokens=1024,
    system=[{
        "type": "text",
        "text": "Large system prompt here...",
        "cache_control": {"type": "ephemeral"}
    }],
    messages=[{"role": "user", "content": "Your question"}]
)
```

## Common Use Cases

### Building a Customer Service Agent
1. Define tools for CRM access, ticket creation, knowledge base search
2. Use tool use API to handle function calls
3. Implement conversation memory
4. Add fallback mechanisms

See: `references/tool_use.md#customer-service`

### Implementing RAG
1. Create embeddings of your documents
2. Store in vector database (Pinecone, etc.)
3. Retrieve relevant context on query
4. Augment Claude's response with context

See: `references/capabilities.md#rag`

### Processing Documents with Vision
1. Convert document to images or PDF
2. Use vision API to extract content
3. Structure the extracted data
4. Validate and post-process

See: `references/multimodal.md#vision`

### Building Multi-Agent Systems
1. Define specialized agents for different tasks
2. Implement routing logic
3. Use sub-agents for delegation
4. Aggregate results

See: `references/patterns.md#agents`

## Best Practices

### API Usage
- Use appropriate model for task (Sonnet for balance, Haiku for speed, Opus for complex tasks)
- Implement retry logic with exponential backoff
- Handle rate limits gracefully
- Monitor token usage for cost optimization

### Prompt Engineering
- Be specific and clear in instructions
- Provide examples when needed
- Use system prompts for consistent behavior
- Structure outputs with JSON mode when needed

### Tool Use
- Define clear, specific tool schemas
- Validate inputs and outputs
- Handle errors gracefully
- Keep tool descriptions concise but informative

### Multimodal
- Use high-quality images (higher resolution = better results)
- Be specific about what to extract/analyze
- Respect size limits (5MB per image)
- Use appropriate image formats (JPEG, PNG, GIF, WebP)

## Performance Optimization

### Prompt Caching
- Cache large system prompts
- Cache frequently used context
- Monitor cache hit rates
- Balance caching vs. fresh content

### Cost Optimization
- Use Haiku for simple tasks
- Implement prompt caching for repeated context
- Set appropriate max_tokens
- Batch similar requests

### Latency Optimization
- Use streaming for long responses
- Minimize message history
- Optimize image sizes
- Use appropriate timeout values
