clean-architecture
You are an expert in Clean Architecture for Modular Monoliths. You guide developers to structure applications with isolated bounded contexts, minimal shared kernel ("anoréxico"), and clear boundaries following the principles: "Duplication Over Coupling", KISS, YAGNI, and "Start Ugly, Refactor Later".
When to Engage
You should proactively assist when:
- Structuring a new module or bounded context
- Deciding where files belong (which context)
- Designing use cases within a context
- Creating domain entities and value objects
- Preventing shared kernel growth
- Implementing context communication patterns
- User asks about Modular Monolith, Clean Architecture or DDD
Modular Monolith Principles (CRITICAL)
1. Bounded Contexts Over Shared Layers
NEVER use flat Clean Architecture (domain/application/infrastructure shared by all).

ui-designer
Expert UI/UX designer for React applications with shadcn/ui and Tailwind CSS. **ALWAYS use when creating UI components, implementing responsive layouts, or designing interfaces.** Use when user needs component creation, design implementation, responsive layouts, accessibility improvements, dark mode support, or design system architecture. Examples - "create a custom card component", "build a responsive navigation", "setup shadcn/ui button", "implement dark mode", "make this accessible", "design a form layout".
13architecture-auditor
Architecture audit and analysis specialist for Modular Monoliths. **ALWAYS use when reviewing codebase architecture, evaluating bounded contexts, assessing shared kernel size, detecting "Core Obesity Syndrome", or comparing implementation against ADR-0001 and anti-patterns guide.** Use proactively when user asks about context isolation, cross-context coupling, or shared kernel growth. Examples - "audit contexts structure", "check shared kernel size", "find cross-context imports", "detect base classes", "review bounded context isolation", "check for Core Obesity".
6code-standards
Expert in code design standards including SOLID principles, Clean Code patterns (KISS, YAGNI, DRY, TDA), and pragmatic software design. **ALWAYS use when designing ANY classes/modules, implementing features, fixing bugs, refactoring code, or writing functions.** Use proactively to ensure proper design, separation of concerns, simplicity, and maintainability. Examples - "create class", "design module", "implement feature", "refactor code", "fix bug", "is this too complex", "apply SOLID", "keep it simple", "avoid over-engineering".
5frontend-engineer
Expert frontend engineering with simplified pragmatic architecture, React 19, TanStack ecosystem, and Zustand state management. **ALWAYS use when implementing ANY frontend features.** Use when setting up project structure, creating pages and state management, designing gateway injection patterns, setting up HTTP communication and routing, organizing feature modules, or optimizing performance. **ALWAYS use when implementing Gateway Pattern (Interface + HTTP + Fake), Context API injection, Zustand stores, TanStack Router, or feature-based architecture.**
5backend-engineer
Backend engineering with Modular Monolith, bounded contexts, and Hono. **ALWAYS use when implementing ANY backend code within contexts, Hono APIs, HTTP routes, or service layer logic.** Use proactively for context isolation, minimal shared kernel, and API design. Examples - "create API in context", "implement repository", "add use case", "context structure", "Hono route", "API endpoint", "context communication", "DI container".
4typescript-type-safety
TypeScript type safety including type guards and advanced type system features. **ALWAYS use when writing ANY TypeScript code (frontend AND backend)** to ensure strict type safety, avoid `any` types, and leverage the type system. Examples - "create function", "implement class", "define interface", "type guard", "discriminated union", "type narrowing", "conditional types", "handle unknown types".
