When to use
Use this skill when the user asks about:
- LangChain agents, chains, RAG, retrieval, memory, tools, or streaming
- LangGraph graph API, functional API, persistence, checkpointing, or subgraphs
- Deep Agents SDK (harness, skills, subagents, sandboxes, memory)
- Integrating LangChain with LLM providers (OpenAI, Anthropic, Google, Bedrock, etc.)
- Vector stores, embeddings, document loaders, or text splitters
- Deploying or scaling LangChain/LangGraph applications
- Migrating to LangChain v1 or LangGraph v1
