[Pragmatic DDD Architecture] Guide for the overall project architecture, Domain-Driven Design (DDD) principles, Modular Monolith (Bounded Contexts) organization, and file structure. Use when deciding where to place a new file, creating a new module, or understanding the application's layers and dependency flow.
Design HTTP APIs for Bun + Hono backends using Clean Architecture, Zod contracts in a shared package, OpenAPI generation from Zod, and thin controllers. Supports two selectable conventions — standard REST (resource paths with GET/POST/PATCH/PUT/DELETE) and POST-only action-based paths — picking one per project. Use when defining new endpoints, auditing or refactoring existing routes, shaping request/response contracts and envelopes, establishing API standards, or mapping typed application errors to HTTP status codes. Do not use for GraphQL, tRPC, non-Hono runtimes, or frontend-only concerns.
Comprehensive guide for production-ready Python backend development and software architecture at scale. Use when designing APIs, building backend services, creating microservices, structuring Python projects, implementing database patterns, writing async code, or any Python backend/server-side development task. Covers Clean Architecture, Domain-Driven Design, Event-Driven Architecture, FastAPI/Django patterns, database design, caching strategies, observability, security, testing strategies, and deployment patterns for high-scale production systems.
Flutter开发完整指南：Clean Architecture架构规范、TDD测试工作流、BLoC状态管理、故障排除与代码生成
Refactor Django/Python code to improve maintainability, readability, and adherence to best practices. Transforms fat views into Clean Architecture with Use Cases and Services. Applies SOLID principles, Clean Code patterns, Python 3.12+ features like type parameter syntax and @override decorator, Django 5+ patterns like GeneratedField and async views. Fixes N+1 queries, extracts business logic from views, separates Read/Write serializers, and converts exception-based error handling to explicit return values. Use when refactoring Django code, applying Clean Architecture, or modernizing legacy Django projects.
Create production-quality Django REST Framework APIs using Clean Architecture and SOLID principles. Covers layered architecture (views, use cases, services, models), query optimization (N+1 prevention), pagination/filtering, JWT authentication, permissions, and production deployment. Use when building new Django APIs, implementing domain-driven design, optimizing queries, or configuring authentication. Applies Python 3.12+ and Django 5+ patterns.
Architecture audit that maps module dependencies, checks layering integrity, and flags structural decay across a codebase, drawing on twelve classic engineering books. Triggers when: user asks to audit architecture, review folder/module structure, check for circular imports, understand how the codebase is organized, or asks "does this follow clean architecture?", "why does everything depend on everything?", "are our layers correct?", "where should this code live?". Also triggers for onboarding requests: "explain this codebase to a new developer" or "give me a codebase tour" (use onboarding mode). Also triggers when user mentions: dependency inversion / hexagonal architecture / bounded contexts / circular imports / tangled dependencies / module coupling / package structure / spaghetti code / directory layout. Use this skill proactively when project structure, module boundaries, or architectural decisions are discussed — even without the word "audit". Do NOT trigger for: PR-level code review (use brooks-review) or line-level refactoring questions — this skill analyzes structural/module-level concerns, not individual functions.
Flutter 단일 패키지 프로젝트의 레이어 구조, 디렉터리 규칙, 의존성 방향을 정리한 스킬. 새 기능을 어디에 둘지, 새 화면·리포지토리·유즈케이스를 어느 디렉터리에 만들지, "폴더 구조를 어떻게 잡을까", "feature를 어디에 둘까", "core에 넣을까 말까" 같은 질문이 나올 때 반드시 사용하세요. "프로젝트 구조", "디렉터리 구조", "레이어 분리", "clean architecture", "where does X live", "새 기능 추가" 같은 표현에 트리거합니다.
Expert in Flutter and Dart development with clean architecture and state management
Universal project bootstrapper: CREATE new or TRANSFORM existing project to production-ready structure
Implements design patterns including Clean Architecture, SOLID principles, and comprehensive software design best practices. Use when designing systems, reviewing architecture, establishing patterns, or making structural decisions.
