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)
