Web & Frontend

Route frontend design and UI implementation prompts to the right design skills. Use for accessibility, frontend visual taste, redesigns, design systems, dashboards, motion, image-to-code, web/mobile image generation, Stitch, Vue conversion, UI demos, or CE frontend design.

React component testing with React Testing Library, Vitest/Jest, MSW for network mocking, accessibility assertions with axe, and the decision boundary between component tests and Playwright/Cypress end-to-end runs. Use when writing or fixing tests for React components, hooks, or pages.

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.

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.

Baseline cross-project coding conventions for naming, readability, immutability, and code-quality review. Use detailed frontend or backend skills for framework-specific patterns.

Backend architecture patterns, API design, database optimization, and server-side best practices for Node.js, Express, and Next.js API routes.

Orquestrador do Time Reversa Docs. Gera um mini-site HTML autocontido em .reversa/documentation/ com arquitetura 3D, dashboards, glossário, deck e páginas por feature, a partir do conhecimento já extraído pelo core do Reversa. Ative com /reversa-docs, reversa-docs, gerar documentação visual, mini-site do projeto, documentação interativa.

Extrai e documenta o sistema de design do projeto legado — paleta de cores, tipografia, espaçamentos, tokens e componentes a partir de CSS, arquivos de tema e screenshots. Use quando arquivos de estilo ou screenshots de interface estiverem disponíveis.

Cria selos visuais generativos seeded usando p5.js, gerando HTML standalone com canvas de arte algorítmica reprodutível. Use esta skill sempre que o usuário pedir um selo, identidade visual de projeto, hero generativo, capa única reprodutível, ou artwork derivado de um hash. Deve ser ativada quando o usuário mencionar termos como "selo", "selo generativo", "identidade visual do projeto", "hero capa", "artwork seeded", "Art Blocks style", "p5.js generativo", "capa reprodutível", "selo de documentação" ou pedir um elemento decorativo único e reprodutível derivado de uma string. Funciona com qualquer string como seed (hash do soul.md, nome do projeto, ID arbitrário). Sempre gera HTML standalone com p5.js via CDN.

Cria visualizações de dados interativas e profissionais usando Highcharts.js, gerando HTML standalone com gráficos animados, responsivos e acessíveis. Use este skill sempre que o usuário pedir para criar gráficos, charts, dashboards, visualizações de dados, ou qualquer representação visual de dados numéricos/categóricos. Deve ser usado quando o usuário mencionar termos como "gráfico", "chart", "dashboard", "highcharts", "visualização de dados", "gráfico de linhas", "barras", "pizza", "scatter", "heatmap", "treemap", "gauge", "stock chart", "mapa", "gantt", "sankey", "funnel", ou quando fornecer dados (CSV, JSON, tabela, planilha) pedindo representação visual. Também deve ser ativado quando o usuário pedir gráficos bonitos, interativos, animados, com tooltip, drill-down, ou exportáveis. Funciona com dados inline, CSV, JSON, e arquivos de dados. Sempre gera HTML standalone completo e funcional.

Atomic-design guidance for UI Atoms — the smallest single-purpose building blocks (buttons, inputs, icons, labels). Use when authoring or reviewing components under ui/atoms, components/atoms, or when deciding whether a component belongs at the atom level.

Pure switch/case reducers for the chota-react-saga template — initial-state file, three-phase async cases per CRUD verb, optimistic mutations with `previousState<Items>` rollback, fall-through SUCCESS/ERROR for toggle and delete.

Selector functions for the chota-react-saga template — colocated with each slice, return derived view-data from the saga state shape (isLoading/isContentLoading/isActionLoading/error/<items>/<current>), filter/sort projections that combine slices (e.g. visibleTodos × selectedFilter).

App Shell architecture — the cached HTML/CSS/JS skeleton (header, nav, footer) served instantly via Service Worker while dynamic content streams in. Use when building PWAs, wiring service-worker caches, inlining critical CSS, or adding offline fallbacks and skeleton loading states.

Writing and publishing blog posts as markdown with front matter into a git-backed static site (Hugo, Jekyll, Astro, etc.), then committing and pushing so CI deploys it.

Create SVG/HTML or Excalidraw diagrams for concepts, architecture, flows, and whiteboards.

Slack tool actions: send/read/edit/delete messages, react, pin/unpin, list pins/reactions/emoji, member info.

Present HTML on connected MarketingClaw node canvases, navigate/eval/snapshot, and debug canvas host URLs.

Discord message-tool ops: send/read/edit/delete, react, poll, pin, thread, search, presence, media/components.

Discover online MetaBots and their services, browse Bot pages in a local browser, and maintain local directory sources for the MetaWeb network.

Convert HTML slides/pages to MP4 video with TTS narration. Playwright screenshots, ffmpeg encoding, edge-tts voice. Jinja2 templates + config.json driven + renderer/encoder separation.

Throwaway HTML mockups: 2-3 design variants to compare.

生成"电子杂志 × 电子墨水"风格的横向翻页网页 PPT（单 HTML 文件），含 WebGL 流体背景、衬线标题 + 非衬线正文、章节幕封、数据大字报、图片网格等模板。当用户需要制作分享 / 演讲 / 发布会风格的网页 PPT，或提到"杂志风 PPT"、"horizontal swipe deck"、"editorial magazine"、"e-ink presentation"时使用。

微信公众号高质量排版引擎 — 中国风主题 CSS + 智能配图（每500-800字一张）+ picsum占位图。替代原有粗糙HTML生成。

Deploy static sites and full-stack apps to PinMe (IPFS-based hosting). One-command upload of HTML/directories, or full-stack project creation with frontend+backend+database. Authentication required — no anonymous upload path exists.

Use when you need to add or debug professional web animations with GSAP (timelines, ScrollTrigger, stagger, transforms) in HTML/CSS/JS/React. Includes patterns for smooth motion, performance, and common pitfalls.

Create strategic HTML presentations with Chart.js, design tokens, responsive layouts, copywriting formulas, and contextual slide strategies.

Use when adding a lightweight interactive globe with cobe (canvas setup, markers, interaction, performance, integration with React/Next.js).

Use when adding animated WebGL background effects with Vanta.js (setup, parameters, resizing, performance, integration in React/Next.js).

Use when implementing globe.gl (Globe.GL) for 3D globe data visualization with WebGL/ThreeJS, including setup, data layers (points, arcs, polygons, labels), and integration patterns in plain HTML or React.

Convert Stitch HTML designs to React Native components, or syncs/updates existing native components to align with the latest Stitch designs, using StyleSheet.

Add accessible animated AI loading and agent-status indicators with the React thinking-orbs library. Use when a chat, copilot, voice, search, generation, or tool-running interface needs a semantic working, searching, solving, listening, composing, or shaping state; when replacing a generic spinner with an AI activity orb; or when implementing the library's size, theme, speed, pause, reduced-motion, and canvas behavior.

Use when fixing, auditing, improving, or building any web UI — before reading or editing component code. Fires on contrast/a11y/overflow/responsive/hover- focus/layout complaints, polish, audit, or any visual change. Never diagnose a UI defect from code alone: render at real viewports, measure (axe / contrast / a11y tree / console / keyboard / reflow), then cite the measurement.

Create React loading, processing, selected, current, focus, and pressed states with the border-beam package's animated edge glow. Use when a card, button, input, tab, option, task panel, or agent surface needs a restrained traveling or breathing beam; includes installation, imports, prop selection, state wiring, reduced motion, accessibility, and performance and layout guardrails.

Converts Stitch designs into modular Vite and React components, or syncs/updates existing React components to align with the latest Stitch designs, using system-level networking and AST-based validation.

Upload local assets (images, mockups, extracted HTML, design markdown) to a Stitch project. ALWAYS use this skill when you need to upload visual assets, HTML pages, or design docs to Stitch, particularly when direct MCP tool calls fail or truncate due to base64 token limits.
