🌆 Aware AI Agent: Weather, Local Insights, and Smart Conversations

"Kya haal hai Delhi ke?" — this simple, casual question triggers an AI-powered agent that not only shares real-time weather updates but also offers local insights about the city. Ask anything — from the best places to visit, to how the job market is — and the agent responds like an informed local.

In this post, we'll walk through how to build an AI agent that: - Detects city names and intent from casual user messages (in Hinglish or English) - Shares live weather updates using the OpenWeather API - Stays in context about that city and answers follow-up questions naturally - Uses chain-of-thought reasoning to answer questions like a thoughtful local

Let's build this intelligent city-aware agent using Google Gemini Flash and Node.js!

🚀 What We'll Build

An AI agent that can:

• ✅ Understand casual city mentions from a variety of user inputs

• ✅ Fetch real-time weather data based on the mentioned city

• ✅ Respond intelligently with insights on that city

• ✅ Remain in "city mode" for all subsequent follow-up questions

• ✅ Use Chain of Thought reasoning to offer detailed, logical responses, like: -

  • "What's famous in Delhi?"

  • "What are the must-visit places in Goa?"

  • "How's the job market in Bangalore?"

The key feature here is that the agent stays focused on the city — and can provide smart, step-by-step reasoning to back its answers.
