SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Enable reliable human-in-the-loop control in LangGraph workflows by pausing execution at decision points, surfacing context to users, and resuming with a structured input.

Core Features & Use Cases

  • Interrupt-based pausing and Command-based resuming for human approval and validation.
  • Support for checkpointer state preservation, thread identification, and JSON-serializable payloads to guarantee safe resumes.
  • Handles subgraphs and multi-interrupt scenarios, including idempotent side effects and error routing.

Quick Start

Invoke this skill to pause graph execution for human input and resume with Command after approval.

Frequently Asked Questions about langgraph-human-in-the-loop

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

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

You can pause LangGraph execution for human approval by triggering an interrupt at designated decision points, then resuming the graph with a Command after the user provides structured input.

Does LangGraph human-in-the-loop support subgraphs and multi-interrupt scenarios?▼

Yes, human-in-the-loop control in LangGraph supports subgraphs and multi-interrupt scenarios, managing idempotent side effects and error routing across complex graph structures.

How do I preserve state when pausing a LangGraph workflow?▼

LangGraph workflows preserve state during pauses using checkpointer-based state saving and thread_id tracking, guaranteeing that execution resumes accurately from the exact interruption point.

What payload format is required to resume a paused LangGraph graph?▼

Resuming a paused LangGraph graph requires JSON-serializable payloads to ensure safe state updates and structured human input transmission via the Command object.

When should I use interrupts in LangGraph workflows?▼

Use interrupts in LangGraph workflows for iterative decision processes, error handling, and approval routes where human validation is necessary before proceeding to the next execution step.
