langchain-orchestration — Claude Code skill: LangChain patterns

A LangChain reference skill for your coding agent: chains, agents, memory, RAG and orchestration. Useful when the agent writes LangChain code and should stick to working patterns.

What langchain-orchestration does

The skill hands your agent a LangChain reference: LCEL, the Runnable interface, sequential chains, map-reduce, routers, conditional branches, agents, memory systems, RAG patterns, callbacks, streaming and error handling. The examples are Python, built on ChatPromptTemplate, RunnablePassthrough, RunnableParallel, RunnableBranch and ChatOpenAI.

It expects Python 3.8+ and these packages installed: langchain>=0.1.0, langchain-core>=0.1.0, langchain-community>=0.0.20. You also need an OpenAI key or credentials for another LLM provider, plus a vector store — FAISS, Chroma or Pinecone. Skip the key or the store and the RAG and model-call examples will not run.

The skill installs into Claude, Codex, Cursor, GitHub Copilot, Gemini CLI and OpenCode. The file lands at a path like .cursor/skills/langchain-orchestration/SKILL.md or ~/.claude/skills/langchain-orchestration/SKILL.md, and the agent reads it whenever LangChain comes up.

What it helps with

  • wire a prompt, model and parser into one LCEL chain
  • route queries to different handlers with a router
  • run map-reduce over several texts in parallel
  • add memory and RAG to a chat agent
  • set up streaming and callbacks for monitoring

Example prompts for the agent

  • Build an LCEL chain with a prompt, ChatOpenAI and StrOutputParser
  • Make a router that sends technical questions to a separate chain
  • Add a RAG pattern with Chroma and memory to the agent
