langchain-rag
INVOKE THIS SKILL when building ANY retrieval-augmented generation (RAG) system. Covers document loaders, RecursiveCharacterTextSplitter, embeddings (OpenAI), and vector stores (Chroma, FAISS, Pinecone).
npx skills add majiayu000/claude-skill-registry --skill langchain-rag-coralshades-acm-ai --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
<overview> Retrieval Augmented Generation (RAG) enhances LLM responses by fetching relevant context from external knowledge sources. **Pipeline:** 1. **Index**: Load → Split → Embed → Store 2. **Retrieve**: Query → Embed → Search → Return docs 3. **Generate**: Docs + Query → LLM → Response **Key Components:** - **Document Loaders**: Ingest data from files, web, databases - **Text Splitters**: Break documents into chunks - **Embeddings**: Convert text to vectors - **Vector Stores**: Store and search embeddings </overview> <vectorstore-selection> | Vector Store | Use Case | Persistence | |--------------|----------|-------------| | **InMemory** | Testing | Memory only | | **FAISS** | Local, high performance | Disk | | **Chroma** | Development | Disk | | **Pinecone** | Production, managed | Cloud | </vectorstore-selection> --- ## Complete RAG Pipeline <ex-basic-rag-setup> <python> End-to-end RAG pipeline: load documents, split into chunks, embed, store, retrieve, and generate a response. ```python from langchain_openai import ChatOpenAI, OpenAIEmbeddings from langchain_community.vectorstores import InMemoryVectorStore from langchain_text_splitters import RecursiveCharacterTextSplitter

What does the langchain-rag skill do?
INVOKE THIS SKILL when building ANY retrieval-augmented generation (RAG) system. Covers document loaders, RecursiveCharacterTextSplitter, embeddings (OpenAI), and vector stores (Chroma, FAISS, Pinecone).
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill langchain-rag-coralshades-acm-ai --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
