About this course
AI coding agents are changing how developers work — but moving beyond “vibe coding” takes real skill. This course teaches you how to use tools like Codex CLI to build serious, maintainable software with AI assistance.
You’ll explore how agentic coding works under the hood, then put that knowledge into practice. Learn spec-driven development, test-driven development (TDD), and context engineering strategies that help you collaborate effectively with AI agents. By the end, you’ll have the techniques to write cleaner code, manage AI context efficiently, and ship projects you’re proud of.
