Summary

The Weather Agent is the classic starter: ask about a place and it reports the current conditions. It geocodes the location and fetches live weather from the free Open-Meteo API — no key required. Reach for it as a minimal, end-to-end example of an agent with a single tool.

Installation

$ pnpm dlx shadcn@latest add @agentcn/langgraph/weather

Customization
