Comprehensive backend development guide for Langfuse's Next.js 14/tRPC/Express/TypeScript monorepo. Use when creating tRPC routers, public API endpoints, BullMQ queue processors, services, or working with tRPC procedures, Next.js API routes, Prisma database access, ClickHouse analytics queries, Redis queues, OpenTelemetry instrumentation, Zod v4 validation, env.mjs configuration, tenant isolation patterns, or async patterns. Covers layered architecture (tRPC procedures → services, queue processors → services), dual database system (PostgreSQL + ClickHouse), projectId filtering for multi-tenant isolation, traceException error handling, observability patterns, and testing strategies (Jest for web, vitest for worker).
Production-grade frontend engineering for Next.js/React, Vue/Nuxt, Angular, Svelte/SvelteKit, Remix, and Vite+React. Use for framework selection, App Router/RSC patterns, TypeScript strict-mode UI code, Tailwind CSS v4 + shadcn/ui, state/data flows (TanStack Query, Zustand), forms validation, testing (Vitest/Testing Library/Playwright), performance (Core Web Vitals), and accessibility (WCAG 2.2).
React, Next.js 16+, TypeScript, shadcn/ui, Tailwind CSS v4, Vite, Vitest 기반 프론트엔드 프로젝트의 기술스택 컨벤션 및 아키텍처 가이드. FE 코드 작성, 리뷰, 리팩토링 시 자동 참조.
Integrate TheSys C1 Generative UI API to stream interactive React components (forms, charts, tables) from LLM responses. Supports Vite+React, Next.js, and Cloudflare Workers with OpenAI, Anthropic Claude, and Workers AI. Use when building conversational UIs, AI assistants with rich interactions, or troubleshooting empty responses, theme application failures, streaming issues, or tool calling errors.
Load PROACTIVELY when task involves writing tests, improving coverage, or test infrastructure. Use when user says "add tests", "write unit tests", "set up E2E testing", "improve coverage", or "add mocks". Covers Vitest/Jest unit tests, React Testing Library component tests, Playwright E2E tests, MSW API mocking, test organization and naming, fixture management, coverage targets and thresholds, snapshot testing, and CI integration.
Production-ready starter project for React + Cloudflare Workers + Hono with core services (D1, KV, R2, Workers AI) and optional advanced features (Clerk Auth, AI Chat, Queues, Vectorize). Complete with planning docs, session handoff protocol, and enable scripts for opt-in features.

Prevents: service configuration errors, binding setup mistakes, frontend-backend connection issues, CORS errors, auth integration problems, AI SDK setup confusion, missing planning docs, incomplete project structure, hours of initial setup. Keywords: cloudflare scaffold, full-stack starter, react cloudflare, hono template, production boilerplate, AI SDK integration, workers AI, complete starter project, D1 KV R2 setup, web app template, chat application scaffold, RAG starter, planning docs included, session handoff, tailwind v4 shadcn, typescript starter, vite cloudflare plugin, all services configured
TypeScript and JavaScript development standards for modern web and Node.js development. Covers strict TypeScript configuration, type safety patterns, ESM modules, async/await, testing with Jest/Vitest, and security best practices. Use when working with .ts, .tsx, .js, .mjs files, package.json, tsconfig.json, or when asking about TypeScript/JavaScript best practices.
Use when scaffolding a new Nuxt 4 project with standard config files (prettier, eslint, gitignore, husky, vitest, tsconfig, sops) and bun scripts.
Build production-grade frontend interfaces with modern React, Tailwind CSS, and shadcn/ui. Five modes: scaffold projects, create components, configure themes and design tokens, refactor styles, and audit codebases. Encodes best practices for React 19 Server Components (framework-dependent), TailwindCSS v4 CSS-first config, shadcn/ui with Radix primitives, modern CSS (container queries, :has(), view transitions, scroll-driven animations), Monaspace typography, and Vite 6. Supersedes the frontend-design skill. Use when building, styling, theming, or improving any frontend project. NOT for backend APIs, database design, DevOps, testing frameworks, state management libraries, routing, or full SSR framework setup.
Answer questions about Module Federation (MF) — configuration, runtime API, build plugins (Webpack/Rspack/Rsbuild/Vite), framework integration (React/Vue/Next.js/Modern.js/Angular), shared dependencies, exposes, remotes, debugging, troubleshooting, and micro-frontend architecture. Use this skill when the user asks anything about module federation, remote modules, shared deps, mf-manifest, federation runtime, or micro-frontends with MF.
Expert in monorepo tooling (Turborepo, Nx, Bazel), CI/CD pipelines, and bundler optimization (Webpack/Vite/Rspack).
Execute a comprehensive React Project Health Audit. Analyzes tech stack, architecture, state management, testing, code quality, performance, CI/CD, and documentation. Produces a Google Docs-ready report with section scores and weighted overall score. Use when the user asks to audit a React project, run a health check, evaluate frontend quality, or assess technical debt. Triggers on: 'react audit', 'health audit', 'react health', 'frontend audit', 'next.js audit', 'vite audit', 'project quality check'.
