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.

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, and more. Every feature is explained clearly - not just what it is, but why it matters and how to use it effectively in real projects.

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.

In this course, you’ll:
  • Learn the fundamentals of working with Codex the right way
  • Understand core commands and context engineering essentials
  • Master advanced, high-impact features like different input modes, agent skills, MCPs, and more
