Writes, optimizes, and debugs C++ applications using modern C++20/23 features, template metaprogramming, and high-performance systems techniques. Use when building or refactoring C++ code requiring concepts, ranges, coroutines, SIMD optimization, or careful memory management — or when addressing performance bottlenecks, concurrency issues, and build system configuration with CMake.
Creates Vue 3 components, builds vanilla JS composables, configures Vite projects, and sets up routing and state management using JavaScript only — no TypeScript. Generates JSDoc-typed code with @typedef, @param, and @returns annotations for full type coverage without a TS compiler. Use when building Vue 3 applications with JavaScript only (no TypeScript), when projects require JSDoc-based type hints, when migrating from Vue 2 Options API to Composition API in JS, or when teams prefer vanilla JavaScript, .mjs modules, or need quick prototypes without TypeScript setup.
Implements advanced TypeScript type systems, creates custom type guards, utility types, and branded types, and configures tRPC for end-to-end type safety. Use when building TypeScript applications requiring advanced generics, conditional or mapped types, discriminated unions, monorepo setup, or full-stack type safety with tRPC.
Rails 7+ specialist that optimizes Active Record queries with includes/eager_load, implements Turbo Frames and Turbo Streams for partial page updates, configures Action Cable for WebSocket connections, sets up Sidekiq workers for background job processing, and writes comprehensive RSpec test suites. Use when building Rails 7+ web applications with Hotwire, real-time features, or background job processing. Invoke for Active Record optimization, Turbo Frames/Streams, Action Cable, Sidekiq, RSpec Rails.
Use when building game systems, implementing Unity/Unreal Engine features, or optimizing game performance. Invoke to implement ECS architecture, configure physics systems and colliders, set up multiplayer networking with lag compensation, optimize frame rates to 60+ FPS targets, develop shaders, or apply game design patterns such as object pooling and state machines. Trigger keywords: Unity, Unreal Engine, game development, ECS architecture, game physics, multiplayer networking, game optimization, shader programming, game AI.
Builds iOS/macOS/watchOS/tvOS applications, implements SwiftUI views and state management, designs protocol-oriented architectures, handles async/await concurrency, implements actors for thread safety, and debugs Swift-specific issues. Use when building iOS/macOS applications with Swift 5.9+, SwiftUI, or async/await concurrency. Invoke for protocol-oriented programming, SwiftUI state management, actors, server-side Swift, UIKit integration, Combine, or Vapor.
Use when building real-time communication systems with WebSockets or Socket.IO. Invoke for bidirectional messaging, horizontal scaling with Redis, presence tracking, room management.
Creates new OrchardCore modules with proper structure, manifest, startup, and patterns. Use when the user needs to create a new module, add content parts, fields, drivers, handlers, or admin functionality.
Tests OrchardCore CMS features through browser automation. Use when the user needs to build, run, setup, or test OrchardCore functionality including admin features, content management, media library, and module testing.
Creates new OrchardCore themes with proper structure, manifest, layouts, and assets. Use when the user needs to create a new theme, customize layouts, or set up frontend assets.
Migrates Vendure Admin UI extensions (legacy Angular-based) to the new React Dashboard.
Migrates Vendure Dashboard extensions from Radix UI patterns to Base UI patterns (@vendure-io/ui).
Admin-side architecture patterns for Webiny extensions. Use this skill when building frontend features with headless features (UseCase/Repository/Gateway), presentation features (Presenter/ViewModel/hooks/components), MobX-based presenters, RegisterFeature, and Admin BuildParams. Covers the admin/ directory structure for both features/ and presentation/ layers.
The hub skill for all API/backend architecture in Webiny. Covers architecture overview, Services vs UseCases, feature naming and organization, feature structure templates, DI decision tree, anti-patterns, createFeature, createAbstraction, container registration, domain errors, entity patterns, naming conventions, scoping rules, and code conventions. Use this skill for ANY backend API work — it references sub-skills for deep implementation details.
Migration patterns for converting v5 Webiny code to v6 architecture. Use this skill when migrating existing v5 plugins to v6 features, converting context plugins to DI services, adapting v5 event subscriptions to v6 EventHandlers, or understanding how v5 patterns translate to v6. Targeted at AI agents performing migrations.
admin/build-params — 3 abstractions.
admin/router — 6 abstractions.
admin/tenancy — 9 abstractions.
API — ACO — 30 abstractions. Folder event handlers and use cases.
