LangGraph interrupt(): Pause Agents for Human Approval

Why a Pause Button Beats a Smarter Prompt

Production agents fail in two ways: they confidently take an action you didn't sanction, or they refuse so often they're useless. The fix is not a better system prompt — it's a pause point. LangGraph 1.2 gives you that pause in one line: interrupt(). The graph freezes, you inspect the proposed action, you approve, edit, or reject, and execution resumes from the exact same state. No re-running the LLM, no lost context.
