Framework

LangChain + Cloudmind

A LangChain callback handler that maps chains, agents, retrievers and tools onto Cloudmind's nested span model automatically.

How it works

Register the Cloudmind callback handler once and the entire LangChain execution tree is traced: chains, agents, retrievers, tools and the model calls underneath each of them.

Retrieval steps record the query, the returned chunks and their similarity scores, which is usually where RAG quality problems actually live.

Setup

import { CloudmindCallbackHandler } from "@cloudmind-ai/js/langchain";

const handler = new CloudmindCallbackHandler();

await chain.invoke({ question: "What is our refund policy?" }, { callbacks: [handler] });
