Frontend

Build and integrate production-ready RAG (Retrieval-Augmented Generation) chatbots into documentation sites using OpenAI, Qdrant Cloud, and Neon Postgres. Handles complete stack from backend API to frontend UI integration.

Comprehensive templates, patterns, and best practices for creating Claude Code subagents and skills. Use when building new agents/skills or need reference examples for proper structure and formatting.

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.

React coding guidelines and best practices. MUST follow these rules. Use when reviewing or writing React code or tasks.

Use when decomposing complex work. Dispatch fresh subagent per task, review between tasks. Flow: Load plan → Dispatch task → Review output → Apply feedback → Mark complete → Next task. No skipping reviews, no parallel dispatch.

This skill should be used when implementing rich, interactive React components in LangGraph applications, including weather dashboards, image galleries, flashcards, charts, forms, and custom visualizations. Use when building new agents with custom UI, retrofitting existing agents with generative UI, or implementing specific component types like galleries or interactive forms.

Get today's date for web searches and date-sensitive tasks. Auto-invoke before any WebSearch that includes a year (e.g., "React 2024", "Python 2025"), when searching for current documentation, latest releases, or recent information. Ensures searches use the correct current year instead of outdated dates.

Creates custom React hooks for SideDish. Use when the user asks to create a new hook, extract shared logic into a hook, or refactor component logic into reusable hooks. Includes TypeScript interfaces, memoization patterns, and index.ts export.

Comprehensive SEO optimization for web applications. Use when asked to improve search rankings, add meta tags, create structured data, generate sitemaps, optimize for Core Web Vitals, or analyze SEO issues. Works with Next.js, Astro, React, and static HTML sites.

Build accessible user interfaces following WCAG guidelines with semantic HTML, keyboard navigation, screen reader support, and proper color contrast. Use this skill when creating or modifying UI components, implementing form inputs, adding interactive elements, working with navigation menus, creating modals or dialogs, or handling focus management. Apply when working on React component files (*.tsx, *.jsx), Shadcn/ui components, or any frontend code that users interact with. This skill ensures semantic HTML elements (nav, main, button, etc.) that convey meaning to assistive technologies, keyboard navigation with visible focus indicators (focus:ring-2 focus:ring-offset-2 in Tailwind), sufficient color contrast ratios (4.5:1 for normal text), descriptive alt text for images and meaningful labels for form inputs, screen reader testing and verification, ARIA attributes for complex components when semantic HTML isn't sufficient, logical heading structure (h1-h6 in proper order), and proper focus management in dyna

Audio, video, and voice components for Composable Svelte. Use when implementing audio players, video embeds, or voice input. Covers AudioPlayer (Web Audio API), VideoEmbed (YouTube/Vimeo/Twitch), and VoiceInput (MediaRecorder) from @composable-svelte/media package.

Comprehensive prompt engineering framework for designing, optimizing, and iterating LLM prompts. This skill should be used when users request prompt creation, optimization, or improvement for any LLM task, or when users need help translating vague requirements into effective prompts through collaborative dialogue and iterative refinement.

Guidance for building, refactoring, and debugging Expo + React Native apps (including Expo Router). Use when wiring screens/layouts, navigation (tab/stack) scaffolding with `_layout.tsx` per group, avoiding unwanted redirects in `app/index.tsx`, theming, data fetching with React Query/fetch, Expo module usage, offline handling, and running local Expo tooling (install/start/lint).

Enriches Jira tasks with comprehensive context, requirements analysis, and technical details through intelligent extraction, dependency mapping, and historical analysis

Structured incremental development workflow that enforces explicit scoping before implementation. Use when: (1) User says 'build', 'implement', 'develop', 'create feature', or 'add functionality', (2) Task involves multiple files or could have ripple effects, (3) User wants to avoid scope creep or premature implementation, (4) Breaking down complex tasks into verifiable steps. This skill prevents AI agents from jumping into code without a validated plan.

UIコンポーネント、スタイリング、レイアウト、デザインシステムを作成する際にブランド一貫性のあるデザインガイドラインを適用する。フロントエンドコンポーネントの構築、デザイン実装、ビジュアル/UXに関する議論の際に使用。Nyatinte BlogのNord風ダークテーマ（Polar Night背景とFrostアクセント）への準拠を保証する。

Use when animating any UI element not covered by specific skills, or when applying general animation principles across multiple element types

Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.

Explicit accessibility enhancement and validation for generated UI code. Only invoke when user explicitly requests accessibility review, a11y enhancement, or WCAG compliance check.

Adding data-slot attributes for CSS targeting and component documentation
