System Documentation

What problem does it solve?

This skill enables developers to implement human-in-the-loop patterns in LangGraph graphs by pausing execution at strategic points, surfacing data for human review, and resuming with provided input.

Core Features & Use Cases

  • Interrupt and resume flows across Python and TypeScript implementations
  • Approval workflows and routing based on human decisions
  • Handling multiple concurrent interrupts and subgraph re-execution semantics
  • Guidance on idempotent side effects and safe checkpointing prior to interrupts
  • Robust resume semantics with Command(resume=...) to restart from the checkpoint

Quick Start

Pause a running LangGraph graph with interrupt(), review the surfaced context, and resume using Command(resume=...) when a decision is provided.
