Boost your agentic engineering game by mastering OpenAI’s Codex agent. From basics to advanced features.

Codex is growing rapidly, and many developers consider it the best or amongst the best agentic engineering tools you can use these days! But unfortunately, many developers are also not using Codex very efficiently though.

If you’ve ever felt like you’re “using” Codex without really mastering it, this course is for you.

Codex – The Practical Guide is a hands-on, no-nonsense course designed to help you unlock Codex’ full potential. You’ll learn how to work with Codex efficiently, understand how it thinks, and confidently use the features that separate casual users from power users.

Yes, you can just start prompting, but to get the most out of it, you should probably go beyond basic, inefficient prompts and leverage the full suite of features Codex offers.

Why Master Codex?
Starting from the fundamentals and quickly moving into advanced territory, you’ll explore essential concepts like context engineering and core commands before diving deep into powerful features such as different input modes, agent skills, MCPs, the Codex SDK, and more. You’ll even learn how to use Codex as a non-coding bot! Every feature is explained clearly: not just what it is, but why it matters and how to use it effectively in real projects.

What’s in This Course?
You don’t need any special setup or prior experience beyond a Codex installation and subscription. By the end of the course, you’ll go from Codex novice to confident, advanced user, able to dramatically boost your productivity and build better software faster.
