Art & Design

The superhero of webdesign skills — builds new websites and audits existing ones against one bar: does it have a real reason to exist, does it solve a business problem, is it beautiful, usable, secure, and GDPR-compliant. For “build me a website” requests, runs a content-approval interview before any implementation. For "check/audit my site" requests, runs the same skill in audit mode against the identical checklist. Use whenever Sinaida asks to build, design, redesign, or review a website, landing page, or web app.

Frontend development patterns for React, Next.js, state management, performance optimization, and UI best practices. Use when building or reviewing React or Next.js components, state, or render performance.

tasteskill v2, the anti-slop frontend skill. Art direction for websites, distilled from a study of 247 curated gallery sites (One Page Love, Awwwards Sites of the Day). Deals researched directions (idea, composition, type, palette, photographs, section blueprints) from a library, enforces a strict no-slop house style with a real-browser inspector, and runs a look-and-fix loop on screenshots. Use this whenever you build, design, redesign, restyle, polish or review a landing page, marketing site, portfolio, product page, one-pager, hero or any public-facing web page, in any stack (HTML/CSS, React, Next.js, Vue, Svelte, Astro, Tailwind) — also when the user says a page looks generic, templated, "AI-made", sloppy, or asks to make it look designed, premium, award-level or less like every other site. Not for dashboards or app screens.

Release develop to main (the live site): release notes, merge, tag, push, and check the Netlify production deploy. Run only when Karolina asks for a release.

Apple's approach to interface design and fluid, physical motion, translated for the web. Use when building or reviewing gesture-driven UI, spring animations, drag/swipe/sheet interactions, momentum and interruptible transitions, translucent materials and depth, typography (optical sizing, tracking, leading), reduced-motion, or the design foundations (feedback, spatial consistency, restraint) behind Apple-style interfaces.

Implement or refine the portfolio's landing page Prism-style project carousel and Projects page album-rail graphic gallery. Use when the user refers to either carousel, its scroll transitions, or asks to reuse the visual/interaction pattern in this project.

Commit a finished change on develop the way this repo expects - yarn verify, semver bump, CHANGELOG entry, own files staged by name, version in the subject, push. Use whenever a change is ready to commit.

Personal developer blog and portfolio design with a narrow reading column, serif post text, warm neutrals and one green accent, light and dark mode with a toggle, writing grouped by year, reading time, post outline, author box, previous and next posts, project tiles with tech pills and an experience timeline.

Ultra-compressed communication mode. Cuts output tokens 65% (measured) by speaking like caveman while keeping full technical accuracy. Supports intensity levels: lite, full (default), ultra, wenyan-lite, wenyan-full, wenyan-ultra. Use when user says "caveman mode", "talk like caveman", "use caveman", "less tokens", "be brief", or invokes /caveman. Also auto-triggers when token efficiency is requested.

Extract any website's design system into an agent-ready DESIGN.md using Firecrawl scrape evidence. Use when the user wants colors, fonts, spacing, components, layout patterns, or brand/UI guidance from a website so AI agents can create new websites, clone a look, or build pages inspired by that design.

Set an ECC-specific frontend design direction for production UI work. Use when building or improving websites, dashboards, applications, components, landing pages, visual tools, or any web UI that needs stronger product-specific design judgment.

Invoke for frontend UI/UX best practices: responsive design, mobile adaptation, accessibility (a11y), animation performance, CSS, layout, component libraries, theming, dark mode, screens/resolutions, fonts, typography, color, interaction, UX, design systems, form validation, loading/empty/error states, navigation, route transitions, micro-interactions. Chinese triggers: 响应式 / 移动端适配 / 无障碍 / a11y / 动画 / 布局 / 组件库 / 主题 / 暗黑模式 / 排版 / 设计系统 / 微交互.

>- Build and improve user interfaces with coherent visual design, responsive layout, accessible interaction, and reliable state. Use for pages, components, forms, frontend behavior, and UI polish. Follow the project's framework and design system and verify rendered behavior rather than relying on source or screenshots alone.

Document frontend data needs for backend developers. Use when frontend needs to communicate API requirements to backend, or user says 'backend requirements', 'what data do I need', 'API requirements', or is describing data needs for a UI.

Accessibility patterns for React and Next.js — semantic HTML, ARIA attributes, form labeling, keyboard navigation, focus management, and screen reader support. Use when building or reviewing forms, modals, dropdowns, tooltips, or tabs, fixing a11y lint or code-review findings, or wiring up keyboard navigation and focus management.

Read-only technical and conversion audit of a live website, made as the before-rebuild snapshot of a B2B site. Crawls up to N same-origin pages (default 10) in headless Chrome and checks mobile layout at 360/390/768 px, bugs (console errors, failed requests, broken links and images, forms without submitting them), accessibility (axe-core, WCAG 2.1 A/AA), performance (Lighthouse or browser timing), the lead path (CTA in the first screen on desktop and phone, contact within 2 clicks, contact info, trust markers) and SEO basics. Writes one markdown report with scores per area, findings P0-P3 (what, where, why it costs leads, fix) and a snapshot to compare after the rebuild, plus raw JSON. Use when the user says "audit this site", "what's wrong with this website", "website audit", "check this URL", "аудит сайту", "технічний аудит сайту", "перевір сайт", "що не так із сайтом". NOT a copywriting audit (use website-copy-reframe), NOT a design system (use design-system-generator).

Create API handoff documentation for frontend developers. Use when backend work is complete and needs to be documented for frontend integration, or user says 'create handoff', 'document API', 'frontend handoff', or 'API documentation'.

Comprehensive patterns for Next.js 14+ App Router architecture, Server Components, and modern full-stack React development.

Next.js 16+ and Turbopack guidance — incremental Rust bundling, file-system caching, faster dev startup and HMR, Turbopack vs webpack tradeoffs, and the middleware.ts to proxy.ts filename change. Use when developing or debugging Next.js 16+ apps, diagnosing slow dev startup or hot reload, choosing between bundlers, or reviewing middleware/proxy file naming.

Frontend development patterns for React, Next.js, state management, performance optimization, and UI best practices.

Next.js App Router principles. Server Components, data fetching, routing patterns.

Frontend development guidelines for React/TypeScript applications. Modern patterns including Suspense, lazy loading, useSuspenseQuery, file organization with features directory, MUI v7 styling, TanStack Router, performance optimization, and TypeScript best practices. Use when creating components, pages, features, fetching data, styling, routing, or working with frontend code.

Expert integration of Supabase Auth with Next.js App Router Use when: supabase auth next, authentication next.js, login supabase, auth middleware, protected route.

Comprehensive frontend development skill for building modern, performant web applications using ReactJS, NextJS, TypeScript, Tailwind CSS. Includes component scaffolding, performance optimization, bundle analysis, and UI best practices. Use when developing frontend features, optimizing performance, implementing UI/UX designs, managing state, or reviewing frontend code.
