Ecosystem Primer
langchain-ai/langchain-skillsBuilding an AI agent means picking the right tool. LangChain, LangGraph, and Deep Agents are three tools from LangChain Inc. Each one works at a different level. This primer helps you choose the best one for your project.
Start by looking at your task. If you need planning and file management, use Deep Agents. If you need custom control flow, use LangGraph. For a simple agent with a fixed tool set, use LangChain. The decision table in this skill makes it easy.
Once you pick a tool, you must load the right skill before writing any code. This saves time and avoids mistakes. Use this primer as your first step in every agent building project.
