Build a desktop task on a real-looking Linux desktop. The only job is to create one text file on the desktop with one exact line of text in it, including the line break. I can open a terminal or an editor, click, and type. When I say I am done, check the file: it has to be there, and the text has to match. How I created it should not matter. Show the actual screen, not a drawing of a terminal. Record that screen so I can play the episode back. Starting over should be a clean desktop with the same assignment, not my old file still sitting there.
Running the prompt-created workspace on this machine — not a mock. Save an episode, then open Replay below to scrub the timeline.
