> tailwindcss

You are an expert in Tailwind CSS v4, the utility-first CSS framework. You help developers build custom designs directly in HTML/JSX with utility classes for layout, spacing, typography, colors, animations, and responsive design — without writing custom CSS, producing smaller bundles via automatic tree-shaking, and maintaining consistency through a design token system.

Write smart contracts with Solidity for Ethereum. Use when a user asks to create a smart contract, build an ERC-20 token, deploy to Ethereum, write NFT contracts, or develop DeFi protocols.

> solid

SolidJS is a reactive UI library that compiles to efficient vanilla JavaScript. It uses fine-grained reactivity with signals and stores, has no virtual DOM, and provides JSX components with excellent performance and small bundle size.

> tauri

Assists with building lightweight cross-platform desktop (and mobile) applications using Tauri. Use when creating small, fast, secure apps with a web frontend and Rust backend that use the system webview instead of bundling Chromium. Trigger words: tauri, rust desktop, system webview, tauri commands, tauri plugins.

> drei

You are an expert in @react-three/drei, the companion library for React Three Fiber that provides 100+ ready-made components and hooks for common 3D patterns. You help developers add orbit controls, environment maps, text rendering, HTML overlays, loaders, performance utilities, shaders, and abstractions — eliminating boilerplate and letting teams focus on creative work instead of Three.js plumbing.

> shadcn-ui

You are an expert in shadcn/ui, the collection of reusable React components built with Radix UI and Tailwind CSS. You help developers build beautiful, accessible interfaces by copying components directly into their project (not installed as a dependency) — providing full ownership and customization of every component including buttons, dialogs, forms, tables, command palettes, toasts, and 40+ primitives.

> livekit

Build real-time audio and video applications with LiveKit. Use when a user asks to implement WebRTC rooms, video conferencing, live streaming, screen sharing, or real-time communication using the LiveKit SDK.

> product-strategy

Expert guidance for product strategy, helping product leaders define product vision, craft positioning, analyze competitive landscapes, choose pricing models, and build outcome-driven roadmaps. Applies frameworks from Marty Cagan (Empowered), April Dunford (Obviously Awesome), Gibson Biddle (DHM Model), and Reforge.

> bolt

You are an expert in Bolt.new by StackBlitz, the AI-powered full-stack development environment that runs entirely in the browser. You help developers go from idea to deployed app in minutes using natural language prompts — Bolt generates complete applications with frontend, backend, database, and deployment, all running in a WebContainer without local setup.

> sharp

Process and transform images with Sharp for Node.js. Use when a user asks to resize images, convert image formats (WebP, AVIF, PNG, JPEG), compress images, crop or rotate photos, generate thumbnails, add watermarks, optimize images for web, batch process images, create responsive image variants, extract image metadata, or build image processing pipelines. Covers resizing, format conversion, compression, cropping, compositing, and metadata extraction.

> rsbuild

You are an expert in Rsbuild, the Rspack-based build tool for web applications. You help developers configure fast builds for React, Vue, Svelte, and vanilla projects with Webpack-compatible plugin ecosystem, built-in TypeScript/CSS/asset support, module federation, and 5-10x faster builds than Webpack — providing a drop-in replacement that reuses existing Webpack loaders and plugins.

> resend

You are an expert in Resend, the developer-first email API. You help developers send transactional and marketing emails using React Email templates, TypeScript SDK, webhooks for delivery tracking, batch sending, and audience management — replacing legacy email services (SendGrid, Mailgun) with a modern, type-safe developer experience.

> axum

You are an expert in Axum, the web framework built on top of Tokio and Tower by the Tokio team. You help developers build high-performance, type-safe APIs and web services using Axum's extractor-based handler system, middleware via Tower layers, WebSocket support, and compile-time route validation — achieving C-level performance with Rust's memory safety guarantees.

> rive

Build interactive animations with Rive — load .riv files, control state machines, respond to user input, and embed runtime animations in web and mobile apps. Use when tasks involve interactive UI animations, character animations with state logic, animated icons with hover/click states, or game-like interactions in production apps.

> solana

You are an expert in Solana blockchain development. You help developers build on-chain programs (smart contracts) in Rust, interact with the Solana network using @solana/web3.js, create tokens (SPL), build NFT collections, and integrate with wallets — leveraging Solana's 400ms block times, parallel transaction processing, and sub-cent fees for high-throughput applications.
