48-hour MVP: idea → deployed app

Day 1 (AM) — Decide

• 30-min problem interview notes → 1-page PRD
• Cut scope until one painful workflow remains
• Pick stack you’ve shipped before (mine: TanStack Start + Postgres)

Day 1 (PM) — Skeleton

• pnpm create → auth stub → one model → one list view
• Deploy to staging before dinner (forces env discipline)

Day 2 — Polish + ship

• Happy path only; no settings page yet
• Seed demo data; record 90-sec Loom
• Production deploy + error monitoring

Agent rules that matter

• Commits every 20–30 min
• “No abstractions until second use”
• Run pnpm test before calling a task done

Proof

Last month: niche B2B form tool — Thursday idea, Saturday paid pilot.
