Skill Claude CodeCodex

Build RAG (Retrieval-Augmented Generation) pipelines with LangChain. Use when loading documents, chunking text, setting up vector stores, creating retrievers, or building question-answering systems. Covers document loaders, text splitters, embeddings, and all major vector stores.

Codeblockz/langchain-community-plugin

Skill Claude CodeCodex

Build AI agents with LangGraph using best practices. Use when creating agents, workflows, tool-calling systems, or multi-agent architectures in Python. Covers createagent (simple) and StateGraph (custom) APIs with state management, persistence, streaming, and human-in-the-loop patterns.
