Performs code upgrades, migrations, and transformations using the AWS Transform (ATX) CLI. Use when upgrading language versions, migrating AWS SDKs, migrating frameworks (Angular, Vue.js, Spring Boot, React), upgrading libraries, optimizing performance, migrating x86 to Graviton, analyzing codebases / generating documentation, or defining custom transformations with natural language. Runs locally on a few repositories or at scale across hundreds via AWS Batch/Fargate.
Production-grade frontend engineering for Next.js/React, Vue/Nuxt, Angular, Svelte/SvelteKit, Remix, and Vite+React. Use for framework selection, App Router/RSC patterns, TypeScript strict-mode UI code, Tailwind CSS v4 + shadcn/ui, state/data flows (TanStack Query, Zustand), forms validation, testing (Vitest/Testing Library/Playwright), performance (Core Web Vitals), and accessibility (WCAG 2.2).
[Utilities] Design intelligence database for UI/UX decisions (tech-agnostic). Use FIRST when planning beautiful interfaces - provides style recommendations, color palettes, font pairings, UX guidelines BEFORE implementation. Searchable: 50 styles (glassmorphism, minimalism, brutalism), 21 color palettes, 50 font pairings, chart recommendations, landing page structures, accessibility patterns. Works with any stack (React, Vue, Angular, Flutter). For React component implementation, use shadcn-tailwind instead. Triggers on: beautiful UI, design system, color palette, font pairing, UX review, style guide.
Ionic Capacitor mobile app development with Angular, React, or Vue. RevenueCat payments, AdMob ads, i18n localization, onboarding flow, paywall, and Ionic Tabs navigation.
Guides the agent through Ionic Framework development with React — project structure, React-specific Ionic components, IonReactRouter and navigation patterns, Ionic lifecycle hooks (useIonViewWillEnter, useIonViewDidEnter, useIonViewWillLeave, useIonViewDidLeave), state management integration, and React-specific best practices for Ionic apps. Do not use for plain Capacitor React apps without Ionic (use capacitor-react), Ionic with Angular or Vue, creating a new Ionic app (use ionic-app-creation), upgrading Ionic to a newer version (use ionic-app-upgrades), or general Ionic component usage without React-specific context (use ionic-app-development).
Implement Syncfusion Windows Forms TreeMap control for hierarchical data visualization with nested rectangles. Use this when working with TreeMap controls, hierarchical data display, space-efficient charts, or color-coded visualizations. Covers TreeMap configuration, layout algorithms, color mapping, and customization for stock market visualizations and data categorization with rectangular layouts.
Install and wire markstream-vue, markstream-react, markstream-vue2, or markstream-angular into an existing repository. Use when Codex needs to choose the right package, install the smallest peer-dependency set, fix CSS/reset order, decide between `content` and `nodes`, or add a minimal working renderer example.
Full browser UAT for web apps — Playwright testing with console/network error capture, accessibility checks, i18n validation, and bug triage. Use when running screen-by-screen UAT or testing specific features in any web or hybrid app (React, Vue, Angular, Ionic, Next.js, etc).
Expert frontend developer specializing in modern web technologies, React/Vue/Angular frameworks, UI implementation, and performance optimization
Accessibility audit skill for scanning, fixing, and verifying WCAG 2.2 Level A and AA compliance across React, Next.js, Vue, Angular, Svelte, and plain HTML codebases. Use when auditing accessibility, fixing a11y violations, checking color contrast, generating compliance reports, or integrating accessibility checks into CI/CD pipelines.
Build and deploy full-stack web and mobile apps with AWS Amplify Gen2 (TypeScript code-first). Covers auth (Cognito), data (AppSync/DynamoDB including schema modeling, enum types, relationships, authorization rules), storage (S3), functions, APIs, and AI (Amplify AI Kit with Bedrock). Supports React, Next.js, Vue, Angular, React Native, Flutter, Swift, and Android. Always use this skill for Amplify Gen2 topics — even for questions you think you know — it contains validated, version-specific patterns that prevent common mistakes. TRIGGER when: user mentions Amplify Gen2; project has amplify/ directory or amplify_outputs; code imports @aws-amplify packages; user asks about defineBackend, defineAuth, defineData, defineStorage, or npx ampx. SKIP: Amplify Gen1 (amplify CLI v6), standalone SAM/CDK without Amplify (use aws-serverless), direct Bedrock without Amplify AI Kit (use bedrock).
Explain how CE.SDK Web features work — concepts, architecture, and workflows. Covers React, Vue.js, Svelte, Angular, Electron, Vanilla JavaScript, Node.js, Nuxt.js, Next.js, SvelteKit. Use when the user says "explain", "how does X work", "walk me through", "what is", "describe", or wants to understand a CE.SDK concept at a conceptual level for Web development. Generates custom markdown explanations with diagrams and code examples. Not for looking up existing docs (use docs-{framework}), not for writing implementation code (use build). <example> Context: User wants to understand how text layers work user: "Explain how text layers work in CE.SDK" assistant: "I'll use /cesdk:explain to generate a detailed explanation." </example> <example> Context: User needs a concept explained in their context user: "How does the block hierarchy work for video editing?" assistant: "Let me use /cesdk:explain to create a custom explanation for video block hierarchy." </example> <example> Context: User needs to understand a workflow user: "Walk me through the asset loading pipeline" assistant: "I'll use /cesdk:explain to explain the asset pipeline." </example>
