SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses the need to pause AI agent execution for human input, manage approvals, and handle errors gracefully within LangGraph applications.

Core Features & Use Cases

  • Human-in-the-Loop: Pause graph execution to surface data to users for review or decision-making.
  • Resumable Execution: Resume paused execution with user-provided input using Command(resume=...).
  • Error Handling: Provides patterns for user-fixable errors and integrates with a broader error handling strategy.
  • Use Case: An AI agent drafting an important email can pause execution using interrupt(), present the draft to a manager for approval, and then resume to send the email if approved, or end the process if rejected.

Quick Start

Use the langgraph-human-in-the-loop skill to pause execution and wait for user approval before proceeding.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I pause LangGraph execution for human approval?▼

To pause LangGraph execution for human approval, use the interrupt() function to suspend the graph, surface data to the user for review, and then resume processing with Command(resume=...) once the user input is provided.

What is a human-in-the-loop workflow in LangGraph?▼

A human-in-the-loop workflow in LangGraph is an execution process that pauses agentic tasks to surface data for human review or decision-making, enabling users to provide direct input, validate actions, or approve operations.

Do I need a checkpointer to resume a paused LangGraph graph?▼

Yes, you need a checkpointer to resume a paused LangGraph graph. Checkpointer requirements and thread ID configurations are necessary to manage the interrupt and resume commands for seamless integration of user feedback.

How do I handle user-fixable errors in LangGraph agents?▼

Handle user-fixable errors in LangGraph agents by pausing execution with interrupt() to present the error to the user, then apply provided corrections and resume the graph using Command(resume=...) within a validation loop.

Can I manage multiple interrupts in a single LangGraph execution?▼

Yes, you can manage multiple interrupts in a single LangGraph execution. The Skill provides patterns for multiple interrupt handling, allowing several pause and resume cycles for user feedback throughout the agentic process.
