# LangGraph Routing Skill

## Capabilities

- Design conditional edge routing in LangGraph

- Implement state-based transition logic

- Create dynamic routing functions

- Handle multi-path workflow branches

- Implement router nodes for complex decisions

- Design fallback and error routing paths

## Target Processes

- langgraph-workflow-design

- plan-and-execute-agent

## Implementation Details

### Routing Patterns

1. **Conditional Edges**: add_conditional_edges with routing functions

2. **Router Nodes**: Dedicated nodes for routing decisions

3. **State-Based Routing**: Routing based on state values

4. **LLM-Based Routing**: Using LLM to determine next node

### Configuration Options

- Routing function definitions

- Path mapping configurations

- Default/fallback routes

- Cycle detection settings

- Max iteration limits

### Best Practices

- Clear routing logic documentation

- Handle all possible states

- Implement fallback paths

- Avoid infinite cycles

- Use descriptive edge names

### Dependencies
