LangChain

LangChain callback handler that writes local AgentInspect JSONL traces.

Install

bash

npm install agent-inspect @agent-inspect/langchain @langchain/core

Example

import { AgentInspectCallback } from "@agent-inspect/langchain";

const handler = new AgentInspectCallback({
  traceDir: ".agent-inspect",
  runName: "my-chain",
  persist: true,
});

// Pass handler to your chain / runnable callbacks

Privacy

Keep `capture: "metadata-only"` for shareable examples. Review `preview` traces carefully because previews can include prompt or output fragments.
