Individual skill

create-app

Guided journey from a raw app idea to a validated, cleanly architected first version that ships on a sustainable cadence. Orchestrates ten skills phase by phase - lean-startup, design-sprint, clean-architecture, domain-driven-design, clean-code, pragmatic-programmer, system-design, ios-hig-design, 37signals-way, software-design-philosophy - asking the user questions at every decision point and recording results in the project docs/ folder (PRODUCT.md, ARCHITECTURE.md, EXPERIMENTS.md, CREATE-APP-PLAN.md) so the journey resumes across sessions. Use when the user wants to build a new app, validate an idea before writing code, architect an MVP that will not need a rewrite, or says 'help me build my app the right way'. App already exists: use improve-app or grow-app. Business idea not yet validated: run create-business first. Marketing site only: use create-website. Architecture-only question: design-code-architecture. For one framework in isolation, invoke that skill directly.

# Create an App

Take a raw app idea to a validated, cleanly architected first version that ships on a sustainable cadence — without over-building for scale you have not earned, or writing a prototype that calcifies into a rewrite. This journey runs ten phases: it asks before every decision and records each choice in `docs/` so you can stop and resume across sessions. The early phases often produce no code at all; once an experiment greenlights building, the engineering phases build the real thing well.

## Core Principle

**Validate fast while keeping options open: make the expensive-to-reverse decisions early and defer everything cheap.** Spend scarce early effort on the few things that compound — the riskiest assumption, the dependency boundaries, the domain language — and aggressively avoid waste everywhere else.

This skill sequences the phases, asks the questions, and records the decisions; the constituent skills carry the method. Invoke them rather than improvising their frameworks.
