Declarative web framework for building browser-based 3D, VR, and AR experiences using HTML and entity-component architecture. Use this skill when creating WebXR applications, VR experiences, AR experiences, 360-degree media viewers, or immersive web content with minimal JavaScript. Triggers on tasks involving A-Frame, WebXR, VR development, AR development, entity-component-system, declarative 3D, or HTML-based 3D scenes. Built on Three.js with accessible HTML-first approach.
Diagnoses and fixes .NET MAUI development environment issues. Validates .NET SDK, workloads, Java JDK, Android SDK, Xcode, and Windows SDK. All version requirements discovered dynamically from NuGet WorkloadDependencies.json — never hardcoded. Use when: setting up MAUI development, build errors mentioning SDK/workload/JDK/Android, "Android SDK not found", "Java version" errors, "Xcode not found", environment verification after updates, or any MAUI toolchain issues. Do not use for: non-MAUI .NET projects, Xamarin.Forms apps, runtime app crashes unrelated to environment setup, or app store publishing issues. Works on macOS, Windows, and Linux.
Monorepo tooling, task orchestration, and workspace architecture for JavaScript/TypeScript repositories. Use when setting up Turborepo, Nx, pnpm workspaces, or npm workspaces; designing package boundaries; configuring remote caching; optimizing CI for affected packages; managing versioning with Changesets; or untangling circular dependencies. Activate on "monorepo", "turborepo", "nx", "pnpm workspace", "task pipeline", "remote cache", "changesets", "CODEOWNERS", "circular dependency", "affected packages", "workspace". NOT for git submodules or multi-repo federation strategies, non-JavaScript monorepos (Bazel, Pants, Buck), or single-package repository setup.
Helps users create and initialize new Tauri v2 projects for building cross-platform desktop and mobile applications. Covers system prerequisites and setup requirements for macOS, Windows, and Linux. Guides through project creation using create-tauri-app or manual Tauri CLI initialization. Explains project directory structure and configuration files. Supports vanilla JavaScript, TypeScript, React, Vue, Svelte, Angular, SolidJS, and Rust-based frontends.
URL content extraction. Use for fetching any URL - webpages, articles, PDFs, JavaScript-heavy sites. Token-efficient: runs in forked context. Prefer over built-in WebFetch.
You are a Senior Front-End Developer and an Expert in ReactJS, NextJS, JavaScript, TypeScript, HTML, CSS and modern UI/UX frameworks (e.g., TailwindCSS, Shadcn, Radix). You are thoughtful, give nuanced answers, and are brilliant at reasoning. You carefully provide accurate, factual, thoughtful answers, and are a genius at reasoning.
React performance optimization guidelines for Single Page Applications (SPA) at Workleap. Use when writing, reviewing, or refactoring React SPA code to ensure optimal performance patterns. Triggers on tasks involving React components, state management, bundle optimization, re-render prevention, rendering performance, or JavaScript performance improvements. Covers async waterfall elimination, bundle size reduction, re-render optimization, rendering efficiency, JS micro-optimizations, and advanced React patterns. Does NOT cover server-side rendering (SSR), Next.js, or server components.
Run TypeScript type checking with tsc --noEmit and parse errors into actionable, file-grouped output. Use when validating TypeScript code before commits, after refactors, or when checking for type regressions. Use for "type check", "tsc", "TypeScript errors", "type validation", or pre-commit TypeScript verification. Do NOT use for linting, test execution, runtime errors, or JavaScript-only projects without tsconfig.json.
Upgrade dependencies for Java/Kotlin (Gradle/Maven) and TypeScript/Node projects with minimal risk: plan the bump, apply changes incrementally, run tests/builds, and document breaking changes. Use when the user asks to bump deps, update frameworks, or address CVEs.
Use this skill when you need to control a Chrome browser via CDP (Chrome DevTools Protocol) to reuse existing login sessions. Covers: launching Chrome in debug mode, opening URLs, waiting for page load, evaluating JavaScript, taking snapshots, and extracting auth tokens. Trigger phrases: browser automation, CDP, agent-browser, 浏览器操作, 操作浏览器, Chrome CDP, 复用登录态, extract token from browser.
Cross-platform mobile development with React Native and Expo. Use when building iOS/Android apps with JavaScript/TypeScript, implementing native features, or optimizing mobile performance.
MANDATORY for static requests to find, identify, or list untested source files or modules, sources without tests, source-to-test pairing, test-gap worklists, or suggested test locations. Invoke even for a tiny package; do not substitute manual globbing. Uses Roslyn for C#/.NET and tree-sitter for Python, TS/JS, Go, Java, Rust, and Ruby. DO NOT USE FOR: line/branch coverage, CRAP risk, or grading existing tests.
