SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Enables controlled human-in-the-loop in LangGraph by pausing execution at defined interrupt points and resuming with user input.

Core Features & Use Cases

  • Interrupt-based pausing to surface data or decisions for human review
  • Command(resume=...) to resume execution with the human-provided input
  • Supports checkpointer-driven state persistence, thread_id-driven resume mapping, and routing decisions across subgraphs and parallel branches

Quick Start

Invoke this skill to pause a LangGraph workflow for human approval and resume with the decision.

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 a LangGraph workflow for human approval?▼

Pause LangGraph workflows for human approval by defining interrupt points in the graph. Execution halts at these points to surface data or decisions, allowing human review before the workflow continues processing.

How do I resume a LangGraph workflow after an interrupt?▼

Resume a paused LangGraph workflow by invoking Command(resume=...) with the human-provided input. The checkpointer uses a thread_id to map the resume payload back to the correct interrupted state.

Do I need a checkpointer to use human-in-the-loop interrupts in LangGraph?▼

Yes, human-in-the-loop interrupts require a checkpointer such as InMemorySaver or PostgresSaver to persist state. A thread_id is also required to map the resume command to the correct paused execution thread.

Can I use LangGraph interrupts across subgraphs and parallel branches?▼

Yes, LangGraph interrupts support routing decisions across subgraphs and parallel branches. You can apply interrupt-based pausing for approval, error handling, and validation throughout complex graph structures.

What data format is required for LangGraph interrupt payloads?▼

LangGraph interrupt payloads must be JSON-serializable. This ensures the interrupt data and the subsequent Command(resume=...) inputs can be properly persisted by the checkpointer and mapped via thread_id.

When should I use human-in-the-loop interrupts in LangGraph?▼

Use LangGraph interrupts when workflows require human validation, approval, or error handling. Defining interrupt points pauses execution to surface data for human review before routing decisions or continuing subgraphs.
