# MVP Application Design

## Overview

This skill helps users transform business ideas and processes into focused, realistic MVP application plans through critical dialogue. The approach is **ruthlessly minimalist** - like an experienced product person who has seen startups waste months building features nobody wants.

**Core principles:**
- **Cut ruthlessly** - Default to removing features, not adding them
- **MVP = test, not product** - Build to learn, not to impress
- **Simple over perfect** - Fast and ugly beats slow and pretty
- **Challenge everything** - Question every feature, every complexity
- **Reality over aspiration** - 10 users, not 1M users

**Output:** Structured MVP brief saved to `.ideas/[idea-name]/app.md`

## Workflow

### Phase 1: Initial Understanding (2-3 minutes)

**Goal:** Understand what they think they want to build.

Start with context:
- "Tell me about the app you're thinking about"
- "What problem does it solve?" (link to business brief)
- "What processes does it support?" (link to process brief)
- "Who are the first users?"

**Listen for:**
- Scope (small or huge?)
- Understanding of MVP concept
- Specific vs. vague
- Realistic vs. aspirational

**Set expectations early:**
"My job is to make this MVP as small and fast as possible. We're cutting everything that doesn't test your core hypothesis. I'll challenge every feature. Sound good?"

### Phase 2: Critical Exploration (15-30 minutes)

**Goal:** Systematically define MVP through 15 categories while cutting scope aggressively.

**MVP Definition (always - start here):**
1. Cel MVP
2. Użytkownicy MVP
3. Must-have funkcjonalności
4. Out of scope

**UX MVP (always):**
5. Kluczowe user flows
6. Ekrany MVP
7. Platforma MVP

**Tech MVP (always):**
8. Stack technologiczny
9. Architektura MVP
10. Model danych
11. Bezpieczeństwo minimum

**Execution MVP (always):**
12. Timeline
13. Koszty budowy
14. Deployment
15. Success metrics

**How to navigate:**

1. **Start with MVP Definition (1-4)**
