Hands-on Python with Claude Code · Official demo · Checkpoint l03
The demo shows the human decisions: how the task contract is handed over, when the agent is stopped mid-refactor, how a failure is judged and corrected (uncut), how verify.py gates each step, and how the diff is reviewed at the end.
Official demos — video, terminal replay, and transcripts — are part of the Pro subscription. This includes the demos for free courses: the challenges stay free, the demos do not, and there is no free preview.
What the demo covers: The bounded-change loop with the hard moments kept: the agent proposes a refactor or a new dependency and is stopped; a failure is judged and corrected without cutting the waiting; every gate run of verify.py shown.
The series
One segment per checkpoint; try each challenge yourself first — the demos are the “how”, not a shortcut.
