The /sdlc:init skill automates the complex setup of a professional Software Development Life Cycle (SDLC) environment by scaffolding a standardized pnpm monorepo. It establishes a structured documentation system for requirements, architecture, UX, and testing, while deploying a Storybook-powered 'Planning Hub' for interactive artifact visualization. By integrating a robust suite of quality tools—including ESLint, Vitest, Husky git hooks, and circular dependency detection—this skill ensures that new projects start with enterprise-grade standards and clear visibility for all stakeholders from day one.
