Builds composable LLM applications using modern LangChain.js patterns for agents, RAG pipelines, and type-safe structured outputs.
This skill equips Claude with the expertise to architect and implement robust LLM applications using LangChain.js (v1.x). It focuses on modern LangChain Expression Language (LCEL) patterns to create modular, testable chains and sophisticated agentic workflows via LangGraph. By enforcing best practices like Zod-based structured outputs, tool definition via the tool() utility, and integrated LangSmith tracing, it ensures developers avoid legacy pitfalls like AgentExecutor while building scalable, multi-provider AI stacks.
