# OpenRouter Routing Rules

## Overview

This skill covers implementing request-based routing logic to select optimal models based on content, urgency, or cost constraints.

## Prerequisites

- OpenRouter integration
- Understanding of model capabilities and pricing

## Instructions

Follow these steps to implement this skill:

1. **Verify Prerequisites**: Ensure all prerequisites listed above are met
2. **Review the Implementation**: Study the code examples and patterns below
3. **Adapt to Your Environment**: Modify configuration values for your setup
4. **Test the Integration**: Run the verification steps to confirm functionality
5. **Monitor in Production**: Set up appropriate logging and monitoring

## Overview

This skill covers implementing request-based routing logic to select optimal models based on content, urgency, or cost constraints.

## Prerequisites

- OpenRouter integration
- Understanding of model capabilities and pricing

## Basic Routing Strategies

### Content-Based Routing
```python
def route_by_content(prompt: str) -> str:
    """Route to appropriate model based on content analysis."""
    prompt_lower = prompt.lower()

    # Code-related
    if any(word in prompt_lower for word in ["code", "function", "debug", "python", "javascript"]):
        return "anthropic/claude-3.5-sonnet"
