Moh4696/build-ai-agents-free ? reverse-engineered prompt

Build me a simple beginner friendly Python project that shows how to make a real AI agent for free.

I want it to use a free model from Groq, load the API key from a .env file, and work from the command line. Start with a basic agent that can answer questions, then add tools so it can do useful things like web search and a small custom function. It should also include a bit of memory so it can keep track of the conversation instead of acting like a one off chatbot.

Please make the code easy to read, with clear comments, and split into a few small example files so someone can follow along step by step. Include a simple README style setup guide for installing what’s needed, creating the .env file, and running the examples. If anything depends on current model or library details, look up the latest docs online so it still works.
