AI Code Generation Agent (LangGraph + Groq)

This project is an AI-powered coding agent that can plan, architect, and generate complete software projects from a single natural language prompt.

The agent follows a multi-step workflow:

1. Planner – Understands the user request and creates a structured project plan
2. Architect – Breaks the plan into concrete implementation tasks
3. Coder – Writes full, production-ready code files step by step
