vite
Assists with configuring and using Vite as a frontend build tool for modern web applications. Use when setting up dev servers, optimizing production builds, configuring plugins, migrating from Webpack or CRA, or building component libraries. Trigger words: vite, build tool, HMR, hot module replacement, vite config, rollup, bundling.
What this skill does
# Vite ## Overview Vite is a next-generation frontend build tool providing instant dev server startup via native ES modules and optimized Rollup-based production builds. It supports React, Vue, Svelte, and vanilla TypeScript projects with advanced bundling strategies, plugin extensibility, and library mode. ## Instructions - When setting up a project, create `vite.config.ts` with the appropriate framework plugin (`@vitejs/plugin-react`, `@vitejs/plugin-vue`), configure `resolve.alias` with `@` mapping to `src/`, and set environment variables with `VITE_` prefix. - When configuring the dev server, set up API proxying with `server.proxy`, enable HTTPS with `@vitejs/plugin-basic-ssl`, and use `server.watch` polling for containers or VMs. - When optimizing builds, configure manual chunks with `build.rollupOptions.output.manualChunks` for vendor splitting, enable CSS code splitting, and set `build.target` for browser compatibility. - When creating plugins, use the Rollup-compatible plugin API with `resolveId`, `load`, and `transform` hooks, and leverage virtual modules with the `virtual:` prefix. - When building libraries, configure `build.lib` with entry point and output formats (es, cjs, umd), externalize peer dependencies, and use `vite-plugin-dts` for TypeScript declaration generation. - When migrating from Webpack, replace `webpack.config.js` with `vite.config.ts`, swap loaders for Vite plugins, and update `REACT_APP_*` env vars to `VITE_*`. - When integrating testing, use Vitest which shares Vite config and provides instant HMR for tests. ## Examples ### Example 1: Migrate a Create React App project to Vite **User request:** "Convert my CRA project to use Vite instead" **Actions:** 1. Install Vite and `@vitejs/plugin-react`, remove react-scripts 2. Create `vite.config.ts` with React plugin and path aliases 3. Rename `REACT_APP_*` environment variables to `VITE_*` 4. Update `index.html` to reference the entry module directly **Output:** A Vite-powered React project with faster dev startup and HMR. ### Example 2: Configure optimized production build **User request:** "Set up Vite build with vendor chunk splitting and source maps for Sentry" **Actions:** 1. Configure `build.rollupOptions.output.manualChunks` to separate vendor libraries 2. Enable `build.sourcemap` for error monitoring integration 3. Set `build.target` appropriate to browser support requirements 4. Add `build.assetsInlineLimit` tuning for small asset optimization **Output:** An optimized production build configuration with proper chunk splitting and debugging support. ## Guidelines - Always use `import.meta.env.VITE_*` for client-exposed env vars, never `process.env`. - Configure `resolve.alias` with `@` prefix mapping to `src/` for clean imports. - Split vendor chunks manually when default chunking produces too many small files. - Use `build.target: "esnext"` for modern-only apps, `@vitejs/plugin-legacy` for legacy browser support. - Enable `build.sourcemap` in production for error monitoring tools. - Keep `vite.config.ts` clean by extracting complex plugin configs into separate files. - Use `optimizeDeps.include` to pre-bundle problematic dependencies that break during dev.

contribute
IncludedLocal-only OSS contribution command center. Auto-refreshes the user's in-flight PR and issue state on invoke so conversations start with full context — no need to brief Claude on what's in flight. Helps the user find issues to contribute to on GitHub, builds per-repo dossiers of what each upstream expects (CLA, DCO, branch convention, AI policy, draft-first, review bots, issue templates), runs deterministic gates before any external action so AI-assisted contributions don't reach maintainers as slop. State is markdown-only: candidate files at ~/.contribute-system/candidates/, repo dossiers at ~/.contribute-system/research/, append-only event log at ~/.contribute-system/log.jsonl. No database, no cloud calls. Use when the user asks about their PRs / issues / contributions, wants to find new work to take on, claim an issue, build/refresh a repo's dossier, or draft a Design Issue or PR. Trigger with "/contribute", "what's my PR status", "find a contribution", "claim issue X", "draft a Design Issue for Y", "refresh dossier for Z".
architectural-analysis
IncludedUser-triggered deep architectural analysis of a codebase or scoped subtree across eight modes — information architecture, data flow, integration points, UI surfaces, interaction patterns, data model, control flow, and failure modes. This skill should be used when the user asks to "diagram this codebase," "map the architecture," "show the data flow," "give me an ERD," "trace control flow," "find the integration points," "verify the layout pattern," "audit the UX architecture," or any similar request whose primary deliverable is mermaid diagrams plus cited reports under docs/architecture/. Dispatches haiku/sonnet sub-agents in parallel for per-mode exploration, then verifies every citation mechanically before any node lands in a diagram. Not for one-off prose explanations of code (use code-explanation) or for high-level system design from scratch (use system-design).
mcp
IncludedModel Context Protocol (MCP) server development and tool management. Languages: Python, TypeScript. Capabilities: build MCP servers, integrate external APIs, discover/execute MCP tools, manage multi-server configs, design agent-centric tools. Actions: create, build, integrate, discover, execute, configure MCP servers/tools. Keywords: MCP, Model Context Protocol, MCP server, MCP tool, stdio transport, SSE transport, tool discovery, resource provider, prompt template, external API integration, Gemini CLI MCP, Claude MCP, agent tools, tool execution, server config. Use when: building MCP servers, integrating external APIs as MCP tools, discovering available MCP tools, executing MCP capabilities, configuring multi-server setups, designing tools for AI agents.
react-native-skia
IncludedDesign, build, debug, and optimise high-polish animated graphics in React Native or Expo using @shopify/react-native-skia, Reanimated, and Gesture Handler. Use when the user wants canvas-driven UI, shaders, paths, rich text, image filters, sprite fields, Skottie, video frames, snapshots, web CanvasKit setup, or performance tuning for custom motion-heavy elements such as loaders, hero art, cards, charts, progress indicators, particle systems, or gesture-driven surfaces. Also use when the user asks for fluid, glow, glass, blob, parallax, 60fps/120fps, or GPU-friendly animated effects in React Native, even if they do not explicitly say "Skia". Do not use for ordinary form/layout work with standard views.
plaid
IncludedProduct Led AI Development — guides founders from idea to launched product. Six capabilities: Idea (discover a product idea), Validate (pressure-test the idea against fatal flaws, problem reality, competition, and 2-week MVP feasibility), Plan (vision intake + document generation), Design (translate image references into a design.md spec), Launch (go-to-market strategy), and Build (roadmap execution). Use when someone says "PLAID", "plaid idea", "help me find an idea", "product idea", "idea from my business", "idea from my expertise", "plaid validate", "validate my idea", "pressure-test", "is this idea good", "find fatal flaws", "validate the problem", "plan a product", "define my vision", "generate a PRD", "product strategy", "plaid design", "design from image", "translate image to design", "create design.md", "extract design tokens", "plaid launch", "go-to-market", "launch plan", "GTM strategy", "launch playbook", "plaid build", "build the app", "start building", or "execute the roadmap".
nextjs-framer-motion-animations
IncludedAdds production-safe Motion for React or Framer Motion animations to Next.js apps, including reveal, hover and tap micro-interactions, whileInView, stagger, AnimatePresence, layout and layoutId transitions, reorder, scroll-linked UI, and lightweight route-content transitions. Use when the user asks to add, refactor, or debug Motion or Framer Motion in App Router or Pages Router codebases, especially around server/client boundaries, reduced motion, LazyMotion, bundle size, hydration, or route transitions. Avoid for GSAP-style timelines, WebGL or 3D scenes, heavy scroll storytelling, or CSS-only effects unless Motion is explicitly requested.
