Getting Started with Codex

Codex is an AI agent that works in your files and runs real commands — which is exactly why most people never start. This course removes the fear with a simple rule: every workflow comes with clear boundaries and visible proof of what happened.

You begin by setting up your workspace: installing Codex, understanding what it can and cannot touch, and establishing the safety habits that make everything after low-risk. Then you map a real folder so the agent understands your project the way you do, and write project rules — the standing instructions that keep its work inside your conventions without re-explaining yourself every session.

The middle lessons build your working repertoire. You package a skill it can reuse, scout a website and bring back structured findings, and file a run spec — a precise brief for a job you want done, with the checks that prove it was done right. Then you build a real artifact end to end, applying everything at once.

The final lesson is the one most tutorials skip: an honest audit of week one. What did it do well, where did it need supervision, what should stay off-limits for now? You finish with a working setup, seven practiced workflows, and — more valuable than either — calibrated judgment about what to hand an agent and what to keep.
