Connect Codex to the course with one line, then ask the agent the question almost nobody asks it.
What You're Looking At
This is a rehearsal, not a class. The two students are invented — they're the personas we use to test this course on itself — and their conversation with the agent was generated bygpt-5.6-luna, the same model the course runs on, recorded once and replayed since so the run comes out the same every time. Everything else is the software students use: the real pages, the real proxy, the real timer, the real companion. The one thing standing in for itself is the terminal, because students work in Codex and a browser can't record a terminal; that pane shows what genuinely passed through the course's proxy, and never invents output for a command that wasn't run.
Two kinds of substitution are made for publication, and only these two: where a screen would show the rehearsal rig's own 127.0.0.1 address or its scratch folder, it reads as the real one instead; and a setup token is shortened, because a token should never be shown whole even when it's a throwaway from a test database. Nothing else on any screen is altered.
The brief the students actually read is the activity page.
Step by Step
A student on the roster signs in and finds one button. Nothing to configure, nothing to choose.
Pressing it mints a token and shows the line once. If she reloads the page it's gone, and she rotates for a new one.
That's the whole setup: one line, pasted into a terminal. It downloads a script and runs it.
It writes one file: Codex's own config, pointed at the course's proxy with her token in the URL. That output isn't mocked up — the walkthrough fetches the script the page hands out and runs it.
She opens the Codex app without signing in to anything. It's already talking to the course, on the course's account.
Her first message is one the page gives her. It has the agent check its own setup and report back, and make a folder for the site she's about to build.
Everything after this is between her and the agent — but every word of it goes through the course, which is what makes the rest of the semester possible.
The setup page notices on its own. It polls the proxy, so the dot turns over without her doing anything.
Then the brief, which is one sentence long: make a personal website. And the question from the activity page — almost nobody asks an agent this, and it costs one sentence.
That's day one. No editor, no code, no account of her own — a folder, a conversation, and a site by the end of the hour.
