Build voice AI applications using Microsoft's VibeVoice — open-source frontier voice synthesis, recognition, and real-time conversation. Use when: building voice assistants, adding TTS/STT to applications, creating real-time voice chat, voice cloning.

Deploy and configure VictoriaMetrics as a high-performance time-series database for metrics storage and querying. Use when a user needs a Prometheus-compatible long-term storage backend, wants to write MetricsQL queries, configure vmagent for metrics scraping, or set up VictoriaMetrics cluster mode for horizontal scaling.

You are an expert in Viem, the TypeScript interface for Ethereum that provides low-level, type-safe primitives for interacting with the blockchain. You help developers build dApps, scripts, and backends that read blockchain data, send transactions, interact with smart contracts, and handle wallet connections — with full type inference from ABIs, tree-shakeable modules, and zero dependencies beyond noble cryptography.

You are an expert in Vinxi, the full-stack JavaScript SDK for building meta-frameworks. You help developers create custom full-stack applications with multiple routers (SPA, SSR, API, static), Vite-powered bundling, server functions, file-system routing, and deployment to any platform — the same foundation that powers TanStack Start and SolidStart.

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.

Build documentation sites with VitePress, the Vite-powered static site generator. Use when a user asks to create docs, configure VitePress themes, add custom pages, deploy to GitHub Pages, or extend with Vue components.

You are an expert in Vitest, the Vite-native testing framework. You help developers write and run unit tests, integration tests, and component tests with native TypeScript support, Jest-compatible API, built-in mocking, code coverage, snapshot testing, and watch mode — leveraging Vite's transform pipeline for instant test execution without separate compilation.

You are an expert in vLLM, the high-throughput LLM serving engine. You help developers deploy open-source models (Llama, Mistral, Qwen, Phi, Gemma) with PagedAttention for efficient memory management, continuous batching, tensor parallelism for multi-GPU, OpenAI-compatible API, and quantization support — achieving 2-24x higher throughput than HuggingFace Transformers for production LLM serving.

Vue.js is a progressive JavaScript framework for building user interfaces. It features the Composition API with reactive refs and computed values, single-file components, and an approachable learning curve with powerful scaling capabilities.

Build React dApps with wagmi and viem. Use when a user asks to connect wallets in React, read blockchain data in components, send transactions from a frontend, or build a Web3 user interface.

Expert guidance for Wails, the Go framework for building desktop applications with web frontends. Helps developers build lightweight, fast desktop apps where the backend is Go and the frontend is any web framework (React, Vue, Svelte), communicating through auto-generated TypeScript bindings.

Weights & Biases platform for ML experiment tracking, hyperparameter optimization, and artifact management. Log metrics, visualize training runs, run sweeps for hyperparameter tuning, and version datasets and models.

Expert guidance for Warp, the modern terminal built for developer productivity. Helps developers create Warp Workflows (shareable command templates), configure Warp Drive for team knowledge sharing, and leverage Warp's AI features and block-based editing for efficient terminal usage.

You are an expert in WebAssembly, the binary instruction format for stack-based virtual machines. You help developers compile Rust, C, C++, Go, and AssemblyScript to WASM for near-native performance in browsers, edge functions, and serverless environments — building image/video processing, games, crypto, AI inference, and compute-intensive tools that run 10-100x faster than JavaScript.

You are an expert in Weave, the lightweight toolkit by Weights & Biases for tracking and evaluating AI applications. You help developers trace LLM calls, evaluate outputs, compare model versions, track experiments, and debug AI pipelines — with automatic logging via decorators and a visual dashboard for exploring traces, costs, and quality metrics.

Weaviate is an open-source vector database with built-in vectorization modules. Learn schema definition, GraphQL and REST APIs, hybrid search combining BM25 and vectors, and self-hosted deployment with Docker.

Deep web research with Brave Search API. Find sources, extract content, and compile comprehensive reports. Use when a user asks to research a topic on the web, find information online, compile a research report, search the internet for sources, do a deep dive on a subject, gather web sources for a report, or investigate a topic thoroughly using multiple online sources.

Analyze and optimize Core Web Vitals (LCP, CLS, INP) and frontend performance. Use when a user asks to improve page speed, fix layout shifts, reduce loading times, analyze Lighthouse reports, optimize bundle size, or improve Google PageSpeed scores. Covers image optimization, code splitting, font loading, render-blocking resources, and JavaScript execution costs.

Implement passwordless authentication with WebAuthn and Passkeys. Use when: adding passkey/biometric login, implementing FIDO2 authentication, replacing password-based login, building touch ID / face ID authentication flows in web apps. Covers browser API, server verification, and simplewebauthn library.

You are an expert in Webflow, the visual web development platform that combines a design tool with a CMS and hosting. You help teams build responsive websites, landing pages, and content-driven sites using Webflow's visual builder, CMS collections, Ecommerce, form handling, and Webflow APIs — enabling designers to build production websites without writing code while giving developers API access for custom integrations and dynamic content.
