AI Coding Skills for Vue.js

Reverse-engineer any codebase into a complete Product Requirements Document (PRD). Analyzes routes, components, state management, API integrations, and user interactions to produce business-readable documentation detailed enough for engineers or AI agents to fully reconstruct every page and endpoint. Works with frontend frameworks (React, Vue, Angular, Svelte, Next.js, Nuxt), backend frameworks (NestJS, Django, Express, FastAPI), and fullstack applications. Trigger when users mention: generate PRD, reverse-engineer requirements, code to documentation, extract product specs from code, document page logic, analyze page fields and interactions, create a functional inventory, write requirements from an existing codebase, document API endpoints, or analyze backend routes.

Audit and fix responsive design issues across all breakpoints. Scans for fixed widths that cause mobile overflow, missing media query variants, non-responsive images, undersized touch targets below 48px, unreadable typography, and horizontal scroll violations. Auto-detects framework (Flutter, Tailwind, React, Vue, Angular) and responsive system, then fixes layouts with proper flex/grid, clamp-based fluid typography, responsive image sizing, and adequate touch target spacing. Verifies every screen at mobile (375px), tablet (768px), desktop (1280px), and wide (1920px). Use when you need to fix mobile layout bugs, audit responsive breakpoints, fix overflow issues, ensure touch targets meet accessibility minimums, or verify no horizontal scroll at any viewport width.

Probe for hardcoded secrets, injection surfaces, unguarded routes, business logic flaws, and platform-specific weaknesses across backend (Node, Go, Java, Python, Rust), frontend (React, Angular, Vue), and mobile (iOS, Android, Flutter) codebases. Use when performing security audits, vulnerability scans, secrets detection, or penetration testing.

Set up visual regression testing with baseline screenshots across breakpoints. Auto-detects frontend framework (Next.js, React, Vue, Angular, Flutter, Storybook), configures Playwright screenshot comparison, BackstopJS, or Flutter golden tests, captures every page at mobile/tablet/desktop/wide viewports plus interactive states (hover, focus, error, empty, loading), stabilizes dynamic content to prevent false positives, and reports pixel-level diffs. Use when you need to catch unintended UI changes, set up screenshot baselines, prevent CSS regressions, or verify layouts across screen sizes after refactoring.

MUST be used for Vue.js tasks. Strongly recommends Composition API with `<script setup>` and TypeScript as the standard approach. Covers Vue 3, SSR, Volar, vue-tsc. Load for any Vue, .vue files, Vue Router, Pinia, or Vite with Vue work. ALWAYS use Composition API unless the project explicitly requires Options API.

Automated WCAG 2.1 AA accessibility testing with axe-core and Lighthouse CI. Auto-detects frontend framework (React, Next.js, Vue, Angular, Svelte, Astro, Flutter, React Native), discovers all routes and interactive components, installs Playwright + axe-core for page-level scanning and jest-axe/vitest-axe for component-level testing. Generates tests for color contrast (4.5:1), alt text, form labels, ARIA attributes, heading order, landmark regions, focus visibility, keyboard navigation (tab order, focus traps, modal focus management, skip-to-content), screen reader compatibility (aria-live regions, error announcements, toast notifications), and Flutter Semantics validation (48dp touch targets, semanticLabel). Reports violations by severity (critical, serious, moderate, minor) with WCAG criterion references. Use when adding a11y testing, auditing accessibility compliance, fixing contrast issues, or validating keyboard and screen reader support.

Create and present web-based slidedecks for developers using Slidev with Markdown, Vue components, code highlighting, animations, and interactive features. Use when building technical presentations, conference talks, code walkthroughs, teaching materials, or developer decks.

Vue 3 Composition API, script setup macros, reactivity system, and built-in components. Use when writing Vue SFCs, defineProps/defineEmits/defineModel, watchers, or using Transition/Teleport/Suspense/KeepAlive.

Set up internationalization by extracting all hardcoded user-facing strings to locale files. Auto-detects framework (Flutter, Next.js, React, Vue, Angular, iOS, Android) and configures the appropriate i18n library (react-intl, next-intl, vue-i18n, flutter_localizations, NSLocalizedString, strings.xml), generates namespaced translation keys with dot notation, handles pluralization via ICU MessageFormat, sets up date/number/currency formatting per locale, adds RTL layout support for Arabic and Hebrew, and replaces every hardcoded string with translation function calls. Use when you need to add multi-language support, extract hardcoded strings, set up locale files, configure translation workflows, handle pluralization, or add RTL support.

Node.js development guidelines covering Payload CMS, Vue.js with TypeScript, and general TypeScript best practices

Set up production-ready event tracking with Amplitude, Mixpanel, PostHog, or GA4. Auto-detects your framework (React, Next.js, Vue, Flutter, Angular, Python, Go, Rails), installs the correct SDK, creates a provider-agnostic analytics service wrapper, defines a typed event taxonomy, instruments page views and key user flows, and adds privacy/consent controls. Use when you need analytics, event tracking, user tracking, product analytics, usage metrics, or telemetry.

Nuxt full-stack Vue framework with SSR, auto-imports, and file-based routing. Use when working with Nuxt apps, server routes, useFetch, middleware, or hybrid rendering.

Accessibility audit skill for scanning, fixing, and verifying WCAG 2.2 Level A and AA compliance across React, Next.js, Vue, Angular, Svelte, and plain HTML codebases. Use when auditing accessibility, fixing a11y violations, checking color contrast, generating compliance reports, or integrating accessibility checks into CI/CD pipelines.

Use for Vue.js testing. Covers Vitest, Vue Test Utils, component testing, mocking, testing patterns, and Playwright for E2E testing.

Convert frontend code (Vite, React, Angular, Vue, etc.) to a Stitch Design by chaining static HTML extraction, design system extraction, and file upload. **ALWAYS** use this skill when the user's intent is to move existing web apps or React/Angular/Vue components into Stitch (e.g., requests to "save", "migrate", or "upload"). You must use this skill even for simple "save" operations, as it is the only way to ensure the design system is extracted and assets are properly linked.

Pinia official Vue state management library, type-safe and extensible. Use when defining stores, working with state/getters/actions, or implementing store patterns in Vue apps.

Create a library-grade Vue composable that accepts maybe-reactive inputs (MaybeRef / MaybeRefOrGetter) so callers can pass a plain value, ref, or getter. Normalize inputs with toValue()/toRef() inside reactive effects (watch/watchEffect) to keep behavior predictable and reactive. Use this skill when user asks for creating adaptable or reusable composables.

Design distinctive, production-grade frontend UI with bold aesthetic choices. Use when building web components, pages, interfaces, dashboards, or applications in any framework (React, Next.js, Angular, Vue, HTML/CSS).
