Master microinteractions, animations, transitions, and feedback systems. Create intentional, delightful interactions that guide users and provide clear feedback. Includes animation principles, timing, easing, state transitions, and best practices for performance and accessibility.
Scaffolds comprehensive testing setup for Next.js applications including Vitest unit tests, React Testing Library component tests, and Playwright E2E flows with accessibility testing via axe-core. This skill should be used when setting up test infrastructure, generating test files, creating test utilities, adding accessibility checks, or configuring testing frameworks for Next.js projects. Trigger terms include setup testing, scaffold tests, vitest, RTL, playwright, e2e tests, component tests, unit tests, accessibility testing, a11y tests, axe-core, test configuration.
Material Design 3 (Material You) design system knowledge for modern web and Angular applications. Use when implementing Material Design 3 theming, components, typography, color systems, dynamic color, accessibility patterns, or migrating from Material Design 2. Covers design tokens, theming APIs, and Material You principles.
Permission dialog UI for macOS accessibility and privacy settings, replicating the Codex Computer Use guided permissions flow
[production-grade internal] Audits and implements web/mobile accessibility — WCAG 2.2 AA/AAA compliance, screen reader support, keyboard navigation, color contrast, ARIA patterns, and assistive technology testing. Routed via the production-grade orchestrator (Harden mode).
Produce implementation-ready UX and UI specifications: user flows, states, component briefs, design tokens, accessibility constraints, and handoff guidance for frontend engineering agents. Use for new features, redesigns, or design-system work where implementation should follow a clear product and interaction spec.
Color science expert skill with 286K words of reference material covering OKLCH/OKLAB, palette generation, accessibility/contrast, color naming, pigment mixing, and historical color theory.
React 18/19 patterns including hooks discipline, server/client component boundaries, Suspense + error boundaries, form actions, data fetching, state management decision trees, and accessibility-first composition. Use when writing or reviewing React components.
Use when the user is building or refactoring UI in their product codebase and wants designer-quality frontend code — not just functional code. Triggers on phrases like "design better", "make this UI feel more designed", "elevate the design quality", "build this with design best practices", "follow UX heuristics", "make this feel professional", "apply design polish", "review this for craft", or any request to apply UX/UI craft heuristics to code generation or review. Pairs with `docs/design.md` when it exists — the design system file owns **style** (colors, typography, spacing tokens, components), this skill owns **craft** (hierarchy, interaction, accessibility, motion, polish). Reference `docs/design.md` tokens by name for every visual decision; apply the 50-item heuristics catalogue and the Laws of UX catalogue below for every craft decision. When `docs/design.md` is absent, fall back to the codebase's existing design conventions and recommend the **Design System** skill. When a heuristic implies a token the design system doesn't have, flag it as a New Pattern to add via the **Design System** skill — never invent a value inline. Fully standalone.
Modern web design trends, principles, and implementation patterns for 2024-2025. Use this skill when designing websites, creating interactive experiences, implementing design systems, ensuring accessibility, or building performance-first interfaces. Triggers on tasks involving modern design trends, micro-interactions, scrollytelling, bold minimalism, cursor UX, glassmorphism, accessibility compliance, performance optimization, or design system architecture. References animation skills (GSAP, Framer Motion, React Spring), 3D skills (Three.js, R3F, Babylon.js), and component libraries for implementation guidance.
Platform-specific building systems for mobile, VR, and accessibility. Use when implementing touch controls for building games, VR spatial input, colorblind-friendly feedback, or cross-platform building mechanics. Covers input adaptation and inclusive design patterns.
Generate a WCAG 2.2 accessibility audit checklist and remediation suggestions for any UI or design. Use when asked to audit for accessibility, check WCAG compliance, review a design for a11y issues, or create an accessibility remediation plan. Produces a prioritised checklist with pass/fail assessments and specific fixes.
