Back to Track

Deliverable: one feature taken through the complete flow — idea to reviewed PR.

Use your Week 1 project or your main-track project.

1. Define done (posted in Practice #5) — one or two checkable sentences.
2. Prompt with the template. Goal / Context / Boundaries / Done when — for the skeleton and for each fill-in step.
3. Build through the stages. Skeleton → fill-in (small diffs) → polish → tests (cases first, then code; break something to verify a test catches it).
4. Security pass before pushing: .env gitignored, no secrets in the diff or history, every command you approved — one you could explain.
5. PR with the honest description (Week 2 format), plus one new section: a debugging note — what broke during the week and how you got out (rollback? fresh session? better error context?). If nothing broke, say so — and say what you'd have done.
6. Get it reviewed — a separate review chat, a classmate, or a mentor — and respond in small commits.

You are done with Week 3 when

• [ ] Your PR matches the "done" definition you posted at the start — no more, no less.
• [ ] Every prompt in your main thread had goal, context, boundaries, and done-when.
• [ ] Your tests catch a deliberately introduced break.
• [ ] .env is ignored, history is clean, and you can explain every command you approved.
• [ ] Your PR includes the debugging note.
