What problem does it solve? Building pages and components without a consistent architecture leads to tangled logic, router calls scattered through hooks, and untestable UI code. This Skill enforces a strict five-file page pattern that separates types, mapping, logic, navigation, and presentation across standalone Next.js, monorepo web, and monorepo mobile variants. ## Core Features & Use Cases - Five-File Page Structure: Generates types.ts, a pure UIModel mapper, a logic hook without router access, a navigation handler owning the router, and a UI-only page component. - Multi-Variant Support: Provides implementations for standalone Next.js, monorepo web (typed label constants), and monorepo mobile (scopedTranslate, expo-router). - Route Guard Contract: Enforces a machine-parseable JSDoc header declaring routeGuard, unauthRedirect, and postLoginRedirect for every page. - Use Case: When adding a new login screen to a monorepo, use this Skill to scaffold the hook composing shared base hooks, the mapper producing the UIModel, and the thin app route wrapper. ## Quick Start Create a new login page following the page pattern with types, mapper, hook, navigation handler, and a thin route wrapper.
