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.

What this skill does
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. Journey Map Phase Skill Question it answers Artifact --- --- --- --- 1 lean-startup Is the riskiest assumption true, and what is the MVP? Creates docs/PRODUCT.md + docs/EXPERIMENTS.md 2 design-sprint What should the core flow be? Creates docs/DESIGN.md, extends docs/EXPERIMENTS.md — awaiting-evidence 3 clean-architecture What boundaries keep options open? Creates docs/ARCHITECTURE.md 4 domain-driven-design What does the code mean? Extends docs/ARCHITECTURE.md 5 clean-code Is each function readable and tested? Creates docs/TESTING.md 6 pragmatic-programmer Which habits keep it healthy? Extends docs/TESTING.md + docs/TECH-DEBT.md 7 system-design How big must it really be? Extends docs/ARCHITECTURE.md 8 ios-hig-design Does it feel native on iOS? Extends docs/DESIGN.md — iOS only 9 37signals-way What ships, and what is cut? Extends docs/PRODUCT.md + docs/STRATEGY.md 10 software-design-philosophy Where is complexity hiding? Extends docs/TECH-DEBT.md + docs/ARCHITECTURE.md Operating Rules 1. …
