ns-prd — Mobile Product Requirements Document

<objective> Produce a focused PRD for a NowStack Mobile MVP through conversation, then write **`.agents/plan/PRD.md`**. This is the FOUNDATION of the planning pipeline: **PRD → `/ns architecture` → `/ns tasks`**, and it also feeds `/ns setup` (`ns-init-project`) which turns the brief into `site-config.ts`.

Keep it lean (2–3 pages). Mobile-specific from the start: this is an app with an onboarding flow, a paywall, native payments, and store constraints — not a generic web SaaS. If a .agents/plan/PRD.md already exists, read it and offer to refine rather than overwrite. </objective>

<process> ## Phase 1 — Discovery (ask 2–3 questions at a time, never the whole list at once) Do NOT write anything until all six areas are covered. Dig past vague answers; push for specifics.

1. Problem & vision — what problem, for whom, why now, what makes it different, what does success look like.
2. Target users (1–3 personas) — role/context, pain points, motivation to install, what makes them churn or delete the app.
3. Core loop & features — the ONE thing the app must do, the 2–4 must-haves that support it, the nice-to-haves. What's the daily/weekly habit?
4. Mobile shape — platforms (iOS / Android / web /app?), is it offline-capable, does it need push, camera/media, or just content + sync. What does the onboarding teach and what's the activation moment.
5. Monetization — free / one-time IAP / subscription? Price point. Remember the boilerplate's split: Apple IAP on iOS, Stripe on Android/web. What's gated behind the paywall vs free.
6. Success metrics & scope — measurable signals (activation, D7 retention, paywall conversion, not "engagement"), and an explicit NOT building in v1 list.

Phase 2 — Verify completeness

Confirm before writing: core problem + a real user; 1–3 concrete personas; THE critical feature + 2–4 must-haves; platform + monetization decided; specific metrics; explicit out-of-scope. If anything is missing, ask more — do not generate a PRD with gaps.

Phase 3 — Generate .agents/plan/PRD.md

Use the template below. Every feature needs Description / User value / Success metric. Capture the config-relevant facts (title, one-line description, platforms, price + IAP product intent) explicitly so ns-init-project can lift them into site-config.ts.

Phase 4 — Save + next steps

Write .agents/plan/PRD.md. Then point at: /ns architecture (design schema + screens on this stack) → /ns tasks (implementable slices) → /ns setup (apply the brief to site-config.ts). </process>

<constraints> - Max 3–5 must-have features; if the user lists 10, help them cut to the core loop. - Push for measurable metrics (activation %, D7, conversion) — reject "increase engagement". - Conversational, not an interrogation; adapt to their domain. - Mobile reality always present: onboarding, paywall, IAP-vs-Stripe split, store scope. - 2–3 pages, not a 20-page spec. Don't invent legal/company/pricing the user hasn't given. - Write to `.agents/plan/PRD.md` (agent planning artifacts live under `.agents/plan/`, separate from the boilerplate's `docs/`) — not the repo root. </constraints> <verification> - All six discovery areas answered; 1–3 concrete personas; 3–5 must-haves each with a success metric; platform + monetization decided; explicit out-of-scope. - `.agents/plan/PRD.md` written. Next: `/ns architecture`. </verification>
