WeatherDetection Langchain Agent — AI skill for Claude Code

AI community

A hands-on LangChain agent built with Python — implements the ReAct reasoning loop, custom tools (weather + calculator), and supports both live LLMs (Gemini, GPT-4, Claude) and a local simulated model.

README

WeatherDetection LangChain Agent

A LangChain AI agent built by **Sandeep** that uses the ReAct reasoning loop to answer weather queries and perform math calculations using tools.

What it does

Detects weather for cities using a get_weather tool
Evaluates math expressions using a calculate_expression tool
Works with Gemini, GPT-4o, or Claude (via API key) or runs fully locally with a simulated model

How to run

1. Install dependencies

pip install -r requirements.txt

2. (Optional) Set an API key for a real LLM

# Google Gemini
set GOOGLE_API_KEY=your-key-here

# OR OpenAI
set OPENAI_API_KEY=your-key-here

# OR Anthropic Claude
set ANTHROPIC_API_KEY=your-key-here

3. Run the agent

python run_agent_demo.py

No API key? No problem — the agent runs with a built-in simulated model locally.
