microsoft/ai-agents-for-beginners ? reverse-engineered prompt

I want to create a comprehensive course for beginners about building AI agents. Let's structure it as a series of about 15 lessons, where each lesson gets its own folder and a main Jupyter Notebook with Python code examples. The course should start with the absolute basics, like what an AI agent is, and then progress through more advanced concepts. I want to cover key topics like different agent frameworks, design patterns, how to let agents use external tools, and agentic RAG. We should also include lessons on more complex ideas like multi-agent systems, agent memory, and how to get them ready for production. The whole thing should be built using Microsoft's agent framework and Azure AI services. The main goal is to create a complete, easy-to-follow guide for someone new to this field.
