What problem does it solve? Building a full-stack React + Vite app inside a pnpm monorepo involves many coordinated steps — OpenAPI contracts, code generation, database schema, routing, theming, and SEO — and doing them in the wrong order wastes time or produces broken integrations. This Skill orchestrates the entire build workflow, including delegating the frontend to a design subagent, so the app comes together correctly on the first pass. ## Core Features & Use Cases - Structured first-build workflow: Classifies the app (presentation-first, personal utility, CRUD/dashboard, logic-heavy, or interactive game) and splits work between the parent agent and the design subagent accordingly. - Contract-first backend pipeline: Plans the API surface with extra read-only "wow" endpoints, writes the OpenAPI spec, runs Orval codegen, and implements Drizzle schema and routes using exact generated type names. - Design subagent delegation: Launches an async design subagent with generated API hooks, theme files, and relevant skills so the frontend is built in parallel with backend work. - Frontend and SEO references: Ships detailed rules for wouter routing, shadcn forms, Orval hooks, dark-mode theming, test IDs, plus a full SEO implementation guide covering meta tags, sitemaps, structured data, and SPA crawlability. - Use Case: Ask for a habit-tracking app with a dashboard; the Skill writes the OpenAPI spec, runs codegen, launches the design subagent with the generated hooks, builds the Drizzle schema and routes in parallel, seeds data, and finishes with a deploy prompt. ## Quick Start Build me a React + Vite web app for tracking reading lists with a dashboard showing my reading stats.
