You can build a working AI agent in an afternoon: install LangGraph, define a state schema, write two nodes (reason and act), attach a real tool like web search, wire the edges, and run the loop. This guide shows every step.

LangGraph makes agents explicit: nodes are functions, edges are routing logic, and state is a typed dict that persists across every step. In 30 minutes you can build a stateful research agent that searches the web and synthesizes a summary.
