# LangGraph Human-in-the-Loop Skill

## Capabilities

- Implement interrupt points in LangGraph workflows

- Configure human approval gates

- Design intervention interfaces

- Handle workflow resumption after human input

- Implement timeout and escalation logic

- Create notification systems for pending approvals

## Target Processes

- langgraph-workflow-design

- tool-safety-validation

## Implementation Details

### HITL Patterns

1. **Interrupt Before**: Pause before node execution

2. **Interrupt After**: Pause after node for review

3. **Conditional Interrupt**: Context-based pausing

4. **Tool Call Approval**: Review tool invocations

### Configuration Options

- Interrupt node selection

- Approval timeout settings

- Escalation paths

- Notification channels

- State modification permissions

### Best Practices

- Clear approval prompts

- Reasonable timeout defaults

- Proper escalation chains

- Audit logging for approvals

### Dependencies

- langgraph

- langgraph-checkpoint (for persistence)
