Dev Onboarding Builder

Opinionated SwiftUI architecture enforcement for iOS 26 / Swift 6.2 clinic modular MVVM-C apps using local SPM package boundaries. Enforces App-target `DependencyContainer` + route shells, @Observable ViewModels/coordinators, Domain repository/coordinator/error-routing protocols, Data-owned I/O, stale-while-revalidate reads, and optimistic queued sync. Use when writing, reviewing, or refactoring SwiftUI architecture, navigation, dependency wiring, or repository boundaries.

UI/UX design intelligence for web and mobile.

Actions: plan, build, create, design, implement, review, fix, improve, optimize, enhance, refactor, and check UI/UX code. Projects: website, landing page, dashboard, admin panel, e-commerce, SaaS, portfolio, blog, and mobile app. Elements: button, modal, navbar, sidebar, card, table, form, and chart. Styles: glassmorphism, claymorphism, minimalism, brutalism, neumorphism, bento grid, dark mode, responsive, skeuomorphism, and flat design. Topics: color systems, accessibility, animation, layout, typography, font pairing, spacing, interaction states, shadow, and gradient. Integrations: shadcn/ui MCP for component search and examples.

Efficiently develop Hono applications using Hono CLI. Supports documentation search, API reference lookup, request testing, and bundle optimization.

Proactively apply when creating web applications, Node.js services, or any JavaScript project. Triggers on JavaScript, ES6, ES2020, ES2022, ES2024, ES2025, ES2026, modern JS, refactor legacy, array methods, async/await, optional chaining, nullish coalescing, destructuring, spread, rest, template literals, arrow functions, toSorted, toReversed, at, groupBy, iterator helpers, Set union intersection difference, Promise, Promise.try, RegExp.escape, Array.fromAsync, using await using, Temporal, functional programming. Use when writing new JavaScript code, refactoring legacy code, modernizing codebases, implementing functional patterns, checking which ECMAScript edition or runtime supports a feature, or reviewing JS for performance and readability. Modern JavaScript (ES6-ES2026) patterns and best practices.

Use when writing unit tests, adopting Swift Testing framework, making tests run faster without simulator, architecting code for testability, testing async code reliably, or migrating from XCTest - covers @Test/@Suite macros,
