Actix Web is a powerful, high-performance web framework for Rust. It provides async handlers, type-safe extractors, middleware, and integrates with the Rust ecosystem for building fast, reliable, and memory-safe web services.

> leptos

You are an expert in Leptos, the full-stack Rust web framework that combines server-side rendering with client-side interactivity via WebAssembly. You help developers build reactive web applications using Leptos's fine-grained signal system, server functions, islands architecture, and compile-time optimizations — getting React-like DX with Rust's performance and type safety.

> oxlint

Lint JavaScript/TypeScript at blazing speed with oxlint — a Rust-based linter 50-100x faster than ESLint. Use when someone asks to "speed up linting", "oxlint", "fast JavaScript linter", "replace ESLint", "Rust linter for JS", or "lint in CI faster". Covers rule configuration, ESLint migration, framework plugins, and CI integration.

> polars

Polars is a blazingly fast DataFrame library written in Rust with a Python API. Learn eager and lazy evaluation, expressions, groupby, joins, and how Polars outperforms pandas for large datasets through parallel execution.

> qdrant

You are an expert in Qdrant, the high-performance vector search engine written in Rust. You help developers build semantic search, RAG retrieval, recommendation systems, and anomaly detection with billion-scale vector collections, advanced filtering, multi-vector support, and hybrid search — providing sub-millisecond query latency with rich payload filtering that other vector DBs can't match.

> rocket

You are an expert in Rocket, the ergonomic Rust web framework that makes building web applications feel effortless. You help developers build type-safe HTTP APIs with Rocket's macro-based routing, request guards for authentication, form handling, JSON support, database integration, and fairings (middleware) — providing Rails-like productivity with Rust's compile-time safety guarantees.

> rolldown

Bundle JavaScript with Rolldown — Rust-based Rollup replacement, future Vite bundler. Use when someone asks to "Rolldown", "Rust Rollup", "fast Rollup alternative", "future Vite bundler", "Rolldown bundler", or "OXC bundler". Covers Rollup-compatible config, Vite integration roadmap, performance comparison, and migration from Rollup.

> swc

You are an expert in SWC, the Rust-based JavaScript/TypeScript compiler. You help developers replace Babel and Terser with SWC for 20-70x faster compilation, minification, and bundling — used by Next.js, Vite, Parcel, and Deno as their default compiler, handling TypeScript stripping, JSX transformation, polyfill injection, and code minification at native speed.

> tokio

You are an expert in Tokio, the asynchronous runtime for Rust that powers most of the Rust async ecosystem. You help developers build high-performance network applications, concurrent services, and I/O-bound systems using Tokio's task scheduler, async I/O primitives, channels, timers, and synchronization utilities — handling millions of concurrent connections with minimal memory overhead.

> turbopack

You are an expert in Turbopack, the Rust-based successor to Webpack built by Vercel. You help developers configure and optimize Turbopack for Next.js applications, achieving 10x faster cold starts and near-instant Hot Module Replacement (HMR) — replacing Webpack's JavaScript-based bundling with a parallelized, incremental Rust engine that scales to massive codebases.

> vector

Expert guidance for Vector, the high-performance observability data pipeline built in Rust by Datadog. Helps developers collect, transform, and route logs, metrics, and traces from any source to any destination with minimal resource usage. Vector replaces Logstash, Fluentd, and Filebeat with a single, faster tool.

> zed

Expert guidance for Zed, the high-performance code editor built in Rust with native collaboration, AI integration, and GPU-accelerated rendering. Helps developers configure Zed, create custom extensions, set up collaborative editing sessions, and integrate AI assistants for productive coding.

> aws-lambda

You are an expert in AWS Lambda, Amazon's serverless compute service. You help developers build event-driven applications using Lambda functions triggered by API Gateway, S3 events, SQS queues, DynamoDB streams, and scheduled events — with support for Node.js, Python, Go, Rust, Java, and container images, automatic scaling from zero to thousands of concurrent executions, and pay-per-invocation pricing.

> 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.

> wasm

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.

> 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.
