You're building the idea from your Week 4 launchpad. If your idea fits the scope below — build it. If it drifted over the week, trim it now, not on day four.
One week of part-time work. The test: your "done" definition has 3–5 checkable statements, and you can imagine reaching them by mid-week with polish time left. Cut features until that's true — a small finished thing beats a large abandoned one.
Pick the shape that matches your main track:
Web. A small working app or site with a real UI: a tool, a tracker, a landing with interactive parts. Figma → code (Week 1) if you have a design; a clean hand-defined layout if not.
Backend. An API with a few endpoints and a data layer. Required technique: a frontend for verification — after each endpoint, have the agent throw together a simple one-off page that calls it and shows the response. It's a verification tool, not production code: don't polish it, don't grow it. You see your API through a consumer's eyes, without Postman fuss.
Testing. Take an existing app (a classmate's capstone from a previous cohort, your main-track project, a small open-source app) and build its test suite: test cases first, then automated tests through the agent. The special discipline of this variant: agent-written tests get the strictest review of all — verify each one tests real behavior by breaking the thing it claims to cover.
