 "page_title": "How to pause an agent for human approval before it acts with Langgraph",
 "summary": "Use LangGraph interrupts to inspect and edit an agent's state before a risky step runs.",
 "who": "A team building an agent that sends emails, edits records or spends money and wants a person to sign off first.",
 "problem": "Fully autonomous agents can take an action you cannot undo before anyone has looked at it.",
 "outcome": "An agent that stops at chosen points, shows its state for review and continues only after a person approves or edits it.",
 "steps": [
  "Install with `pip install -U langgraph`",
  "Model the agent as a LangGraph graph, putting the risky action in its own step",
  "Follow the Human-in-the-loop guide (interrupts) to pause before that step",
  "Inspect and, if needed, modify the agent state at the pause, then resume the run",
  "Pair it with persistence so a paused run can wait for a reviewer without losing its place"
 ],
 "agent_prompt": "With langchain-ai/langgraph, add a human-in-the-loop interrupt before the <risky action> step of my agent. When it pauses, print the pending state, let me edit it, and only resume after I approve.",
