Frontend

Build accessible web interfaces following WCAG guidelines and assistive technology best practices. Use this skill when creating or modifying UI components that need keyboard navigation, screen reader support, or ARIA attributes. When working on files like components/, pages/, or any file with interactive elements, forms, modals, or dynamic content. When adding alt text to images, labels to form inputs, or managing focus in single-page applications. When implementing color contrast, heading structure, or semantic HTML elements.

Integrates SQLite embedded database with Node.js using better-sqlite3 for synchronous operations or the native Node.js SQLite module. Use when building applications with local storage, embedded databases, or when user mentions SQLite, better-sqlite3, or embedded SQL.

UI component library templates (buttons, forms, cards, modals, etc.). Use when generating frontend UI components.

CSS animations, transitions, and scroll-driven effects with accessibility (prefers-reduced-motion). Use when adding motion, hover effects, loading states, or scroll-based animations.

Spin up local servers and execute dynamic user acceptance testing with Playwright. This skill starts the full stack (backend + frontend), constructs user journeys based on what was just built, and verifies functionality in a real browser.

Build timeout-resistant Claude Code workflows with chunking strategies, checkpoint patterns, progress tracking, and resume mechanisms to handle 2-minute tool timeouts and ensure reliable completion of long-running operations.

Analyze gaps between codebase and PRD documentation, generate discrepancies report. Use this skill when you need to sync documentation with implementation, find undocumented features, or identify unbuilt requirements.

Guides structured evaluation of design options with trade-off analysis. Use this skill when choosing architectures, selecting technologies, evaluating implementation approaches, or making design decisions.

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.

Teaches when to use local state vs global state (Context) in React 19. Use when deciding state management strategy, avoiding prop drilling, or architecting component state.

Write minimal strategic tests during development focusing on core user flows and critical paths, deferring comprehensive edge case testing until after feature completion. Use this skill when writing tests for completed features, testing critical user workflows, implementing integration tests, creating end-to-end tests with Playwright, writing unit tests for core logic, or determining testing strategy and priorities. Apply when working on test files (*.test.ts, *.spec.ts, *.test.tsx), Playwright test files (e2e/*.spec.ts), test configuration, or when deciding what to test during feature development. This skill ensures minimal tests during active development (complete the feature first), focus exclusively on core user flows and critical paths (skip non-critical utilities), deferred edge case and validation testing until dedicated testing phases, behavior testing over implementation details (test WHAT not HOW), descriptive test names that explain the behavior and expected outcome, mocked external dependencies (d

Async/await correctness in React with Zustand. Use when debugging race conditions, missing awaits, floating promises, or async timing issues. Works for both React web and React Native.

Skill for creating and editing Vue.js components following Prowi conventions. Use when writing Vue files, creating components, or refactoring frontend code. Enforces modern patterns like defineModel(), TypeScript, and Composition API.

Creates complete single-file HTML/CSS/JS web apps with localStorage persistence, ADHD-optimized UI (60px+ buttons), dark mode, and offline functionality. Use when user says "create app", "build tool", "make dashboard", or requests any browser-based interface.

Generate TanStack Query hooks for data fetching and mutations. Triggers on "create tanstack query hook", "generate react query", "useQuery hook", "useMutation hook".

Implement GPU scheduling with VRAM budgets, work queues, and model lifecycle management. Use when building ML pipeline orchestrators.

Implement speech-to-text (ASR/automatic speech recognition) capabilities using the z-ai-web-dev-sdk. Use this skill when the user needs to transcribe audio files, convert speech to text, build voice input features, or process audio recordings. Supports base64 encoded audio files and returns accurate text transcriptions.

Builds token-driven Angular components with signals and standalone components. Use when creating Angular component libraries, integrating design tokens, or building design system components with new control flow syntax.

Run pytest test suite for the video processing pipeline with coverage analysis. Use when the user wants to run tests, check test coverage, validate code quality, or verify pipeline functionality.
