System Documentation

What problem does it solve?

Human-in-the-Loop (HITL) workflows pause agent execution to collect approvals, edits, or rejections before continuing, enabling safer and more accountable automation.

Core Features & Use Cases

  • Interrupt-driven approvals: pause on selected tool calls until a human decision is provided.
  • Edit or reject tool calls: modify parameters or halt flows based on reviewer feedback.
  • Resume workflow with a Command: restart agent execution using a structured resume decision.
  • Async and streaming support: handle long-running tasks while awaiting decisions.
  • Use cases: approving data deletions, gating external API interactions, or complex multi-tool workflows.

Quick Start

Run a LangChain agent with HITL enabled to pause for human approval, then resume after a decision is provided.
