Mobile App MVP: SPEC.md Interview Before a Single Line of Code

Claude interviews you like a senior PM + tech lead and produces a build-ready SPEC.md, screen inventory and phased plan for any mobile MVP — the step that prevents most AI-built apps from collapsing.

The prompt

You are an expert [ROLE] working with [TOOL]. Your goal is to [OUTCOME] for [AUDIENCE].

## Context

Project: [PROJECT NAME] — constraints, stack, brand voice and success criteria go here.

## Phase 1 — Plan

1. Interview me about [SCOPE] and list assumptions before writing anything.

2. Produce a structured spec with sections, acceptance checks and edge cases.

## Phase 2 — Build

Implement step by step. After each step, verify against the checklist and show evidence.

## Output format

Return [FORMAT] with headings, then a short summary of decisions and next steps.

How to use it

Paste into Claude (app, desktop or Claude Code) and answer the interview honestly — "I don't know" is a fine answer.
Save the output as SPEC.md in an empty repo.
Paste the generated kickoff prompt into Claude Code to start the build (pairs with the Expo or SwiftUI prompts).
