What you just set up
Step back and see what changed in the last half hour.
You started this chapter able to talk to an AI behind glass. You're ending it with that AI installed on your machine, signed in to your account, and able to do real work in a folder, with your approval at every step that matters. You gave it an English instruction and a file appeared. That is the thing this whole course is building toward, and you've now done it once.
You also have the judgment that goes with the tool. You know the CLI runs a look-plan-act-check loop. You know it asks before it changes things, and that reading the line is your job. You know the difference between thinking work (chat) and doing work (CLI), and you have a rule for picking.
Next: a second tool
The next chapter installs the OpenAI Codex CLI. It's a different company's take on the same idea: an AI that works in your terminal on your files. You're learning it for a simple reason. A builder who only knows one tool is stuck with that tool's bad days and that company's choices. Knowing two means you can pick the better fit for a given job, and you're never trapped.
Almost everything you learned here carries straight over. Install, sign in, start in a folder, give an instruction, watch a loop, approve actions. The Codex chapter is mostly about what's different, which is less than you'd think.

You don't have to be fast at the CLI yet. You've used it once. That's exactly enough to move on. Speed comes from the rest of the course, where the CLI stops being the lesson and starts being the tool you learn everything else with.

Next: ops studio
The next chapter is ops studio. You already opened the CLI door. Ops studio points that same loop at a real process: map the work, automate the safe steps, and name the approval boundary.
Almost everything you learned here carries straight over. Start in a folder, give an instruction, watch a loop, approve actions. The studio is about the process, not a second vendor install.
