What problem does it solve?
This skill addresses the complexity of orchestrating LLM applications by providing a standardized, modular framework for building chains, agents, and RAG pipelines that are observable and production-ready.
Core Features & Use Cases
- LCEL Composition: Build complex LLM workflows using the pipe operator for clean, readable, and modular code.
- Agent Orchestration: Create tool-using agents powered by the LangGraph runtime for streaming, persistence, and state management.
- Production Observability: Integrate LangSmith tracing to debug agent behavior, monitor latency, and evaluate performance in real-time.
- Use Case: Quickly prototype a RAG-based customer support bot that retrieves documentation, uses tools to check order status, and logs all interactions for quality assurance.
Quick Start
Use the langchain skill to initialize a basic LCEL chain that prompts a model to answer a specific question.
