What problem does it solve? Starting a new app from scratch involves dozens of decisions and steps—research, planning, design, testing, security, deployment—that are easy to skip or do in the wrong order. This Skill coordinates the entire zero-to-one lifecycle by delegating each stage to the right specialized skill. ## Core Features & Use Cases - 21-Stage Pipeline: Runs interview, research, planning, design, TDD implementation, security audit, benchmarking, shipping, deployment, and retrospective in sequence, passing outputs between stages. - Stage-0 Interview: Captures platform, target users, repo, budget, external APIs, and deadline before any planning begins, saving answers to a kickoff document. - Delegation with Guardrails: Calls Gstack and simon-stack skills for each phase, enforces TDD guard mode, runs a multi-layer security audit, and supports parallel execution via worktrees. - Use Case: A user says "새 앱 만들자" for a subscription SaaS; the Skill interviews them, researches competitors, produces DESIGN.md and an authz model, drives TDD implementation, audits security, and ships a deployed first release. ## Quick Start Ask the agent to build a new app from scratch, for example: "Help me build a new MVP for a subscription SaaS from zero."
