Multi-provider email sending for Cloudflare Workers and Node.js applications. Build transactional email systems with Resend (React Email support), SendGrid (enterprise scale), Mailgun (developer webhooks), or SMTP2Go (reliable relay). Includes template patterns, webhook verification, attachment handling, and error recovery. Use when sending emails via API, handling bounces/complaints, or migrating between providers.

Build secure desktop applications with Electron 33, Vite, React, and TypeScript. Covers type-safe IPC via contextBridge, OAuth with custom protocol handlers, native module compatibility (better-sqlite3, electron-store), and electron-builder packaging. Use when building cross-platform desktop apps, implementing OAuth flows in Electron, handling main/renderer process communication, or packaging with code signing. Prevents: NODE_MODULE_VERSION mismatch, hardcoded encryption keys, context isolat...

Intelligent debugging workflow that systematically identifies symptoms, performs root cause analysis, generates fixes with explanations, validates solutions, and prevents regressions through comprehensive testing.

Optimize AgentDB performance with quantization (4-32x memory reduction), HNSW indexing (150x faster search), caching, and batch operations for scaling to millions of vectors.

Use when configuring Tailwind CSS-first (no config.js), defining @theme tokens, or creating custom utilities/variants. Do NOT use for v3-to-v4 migration or category utility lookup.

Use when building Apple Watch apps — complications, workouts, HealthKit, or iPhone-Watch connectivity.

Use when building Vision Pro apps — spatial computing, RealityKit 3D content, immersive spaces, or volumes.

Use when building Apple TV apps — focus-based navigation, Siri Remote interactions, or media/video streaming UI.

Use when building SwiftUI views, navigation, persistence, or state management — shared across iOS, macOS, watchOS, visionOS.

Use when implementing Swift 6 fundamentals — concurrency, architecture, testing, i18n, or performance — across any Apple platform.

Use when building Mac apps — menu bar extras, window management, AppKit integration, or notarized distribution outside the App Store.

Use when building iPad apps — split views, external keyboard support, multitasking, or Stage Manager — adaptive layouts.

Use when building iPhone apps — simulator/device testing, UI automation, or debugging — with XcodeBuildMCP tools.

Use when implementing routing in a React app (NOT Next.js) with TanStack Router — file-based routes, loaders, search params.

Zustand v5 state management for React. Use when implementing global state, stores, persist, or client-side state.

Generates high-quality, non-generic UI designs with a focus on performance, progressive disclosure, and distinctive aesthetics.

Advanced TypeScript patterns for type-safe, maintainable code using sophisticated type system features. Use when building type-safe APIs, implementing complex domain models, or leveraging TypeScript's advanced type capabilities.

Use when implementing translations in a React app (not Next.js) with react-i18next — useTranslation, namespaces, pluralization, Suspense.

Use when building type-safe forms in React with TanStack Form v1 — Zod/Yup/Valibot validation, async validation, field arrays.

Use when implementing React 19.3 patterns — use(), useOptimistic, useActionState, useEffectEvent, Activity, ViewTransition, Fragment refs, use(browser()), React Compiler.

Terraform infrastructure-as-code best practices for scalable and maintainable cloud infrastructure. Use when writing Terraform modules, managing infrastructure state, or implementing infrastructure automation at scale.

Use when executing implementation plans with independent tasks in the current session - dispatches fresh subagent for each task with code review between tasks, enabling fast iteration with quality gates
