What will you learn?
Write a toy agentic code editor in Python, similar to Claude Code or Cursor's Agent Mode. Understand how agents work from scratch by using the Google Gemini API to create an LLM-powered code agent. You'll use function calling and feedback loops to build an agent that can find and fix bugs in a real project!

This was a pretty good introduction to the AI agent workflow with Python

The scope of difficulty spikes here rather heavily. By this point you should know all the basics, but due to how the lesson is made, I have slight issues with terms we've never addressed. If your going into this lesson, take it slow, rely on boots and the rest will fall into place. While they do a lot to explain the lesson, I noticed it felt rushed. Assuming they fix that and implement some more guidance, this lesson would be perfect.
