How CODEX Works

Three habits that turn AI from a shortcut into a teacher.

Think

Understand the problem and plan what you want to build before you type a single prompt.

Prompt

Give AI clear instructions and useful context so the answers you get are worth reading.

Build

Test, understand, debug, and improve code until it works and you can explain why.

AI Can Write Code. You Should Know What It Does.

The goal is not faster copying. It is learning to question what AI gives you.

  • Ask AI to explain unfamiliar code.
  • Test generated solutions.
  • Identify and fix bugs.
  • Compare different approaches.
  • Avoid blindly trusting AI-generated output.

Vague Prompt

Make me a website.

Precise Prompt

Create a one-page personal website using HTML and CSS only. Include a header, an about section, and a contact form. Make it readable on phones. Explain each CSS rule in a comment.
