Identify and fix common Next.js App Router anti-patterns and mistakes. Use when reviewing code for Next.js best practices, debugging performance issues, migrating from Pages Router patterns, or preventing common pitfalls. Activates for code review, performance optimization, or detecting inappropriate useEffect/useState usage. CRITICAL: For browser detection, keep the logic in the user-facing component (or a composed helper that it renders) rather than isolating it in unused files.

Validate CasareRPA workflow JSON files for structural integrity, node dependencies, connection validity, and execution requirements.

Autonomous browser agent for complex multi-step web tasks. WHEN: User needs complex web automation, multi-page workflows, form filling sequences, tasks requiring multiple browser actions. WHEN NOT: Simple single-action tasks like one click (use browser_click), one navigation (use browser_navigate), one extraction (use browser_extract_text).

Node.js development standards including jest/vitest, eslint, and prettier. Use when working with JavaScript files, package.json, or npm/pnpm.

Implements privacy-friendly web analytics with Vercel Analytics for traffic insights and Web Vitals. Use when tracking page views and performance metrics in Next.js applications deployed on Vercel.

Search the JLCPCB electronic components database (~7 million parts) for hardware/electronics projects. Use when the user needs to: (1) Find electronic components (resistors, capacitors, ICs, connectors, etc.), (2) Look up specific part numbers or manufacturers, (3) Find alternatives or equivalents for components, (4) Check component availability and stock at JLCPCB, (5) Get component specifications (package type, description, etc.), or (6) Search for parts for PCB assembly projects.

Implements CSS custom properties for theming, component styling, and runtime customization. Use when building theme systems, dynamic styling, or configurable components.

This skill should be used when the user asks to "connect React to agent runtime", "use useAgentSession", "use useMessages", "set up AgentServiceProvider", "stream agent responses", "build agent chat UI", "render conversation blocks", or needs to build a React frontend with @hhopkins/agent-runtime-react.

Xcodeプロジェクトのビルド設定を検証・修正するスキル。推奨設定との比較、問題の検出、修正提案を行う。使用シーン：(1)「ビルド設定を確認して」「プロジェクト設定をチェックして」などの設定検証リクエスト (2)「Swift 6対応の設定になっているか見て」などの特定設定の確認 (3) 新規プロジェクト作成後の設定レビュー (4)「フレームワークの設定が正しいか確認して」などのターゲット別設定確認

Create Zapier zaps, Home Assistant automations, n8n workflows, and webhook integrations. Use when building automations, APIs, or integration flows.

Comprehensive frontend testing patterns including component tests (Jest/Vitest + RTL), visual regression (Playwright), accessibility (axe-core), and performance (Lighthouse) testing for React/Next.js applications. Use when building frontend tests, testing React components, implementing visual regression, running accessibility tests, performance testing, or when user mentions component testing, visual regression, a11y testing, React Testing Library, Jest, Vitest, Lighthouse, or frontend testing.

Use dev-browser for browser automation on NixOS. Invoke when user asks to test UI, automate browser interactions, take screenshots, or verify web app behavior.

Create responsive, mobile-first user interfaces that adapt seamlessly across all device sizes using modern CSS techniques and responsive design patterns. Use this skill when implementing layouts, breakpoints, fluid typography, responsive images, or any UI that needs to work across mobile, tablet, and desktop viewports. Apply this skill when using CSS media queries, container queries, responsive utility classes (Tailwind's sm:, md:, lg:), flexible grid/flexbox layouts, relative units (rem, em, vw, vh), or when optimizing touch interactions for mobile devices. This skill ensures mobile-first development approach, consistent breakpoint usage, proper viewport configuration, touch-friendly target sizes (44x44px minimum), readable typography across all screen sizes, and optimized performance on mobile networks with responsive images and lazy loading.
