Designs and reviews NestJS application architecture using cohesive feature modules, modular monoliths, layered or hexagonal boundaries, dependency inversion, and pragmatic engineering principles. Use when planning a NestJS project, changing module boundaries, evaluating Clean Architecture or DDD, resolving circular dependencies, defining ports and adapters, reviewing coupling, or deciding whether CQRS or microservices are justified. Do not use for pure frontend work or non-NestJS backends. When other skills also apply, reconcile ownership before mutation.
Clean Architecture for .NET applications. Covers the 4-project layout (Domain, Application, Infrastructure, Api), dependency inversion, use case handlers, domain entities with behavior, and infrastructure as a plugin. Load this skill when building a project with Clean Architecture, discussing layered architecture, dependency inversion, use cases, or when the architecture-advisor recommends Clean Architecture.
Provides comprehensive guidance for hexagonal architecture including ports and adapters, domain isolation, and dependency inversion. Use when the user asks about hexagonal architecture, needs to implement ports and adapters pattern, or structure applications with hexagonal architecture.
Object-oriented design principles including object calisthenics, dependency inversion, fail-fast error handling, feature envy detection, and intention-revealing naming. Triggers on: writing new classes or functions, refactoring, code review, 'clean up', method longer than 10 lines, feature envy, primitive obsession, deep nesting.
Comprehensive guidance for Onion Architecture (洋葱架构) — Jeffrey Palermo's onion architecture with domain-centric layered isolation, dependency inversion from outer to inner rings. Covers domain core, application interfaces, infrastructure implementation, and API adapters with full Java/Spring Boot examples. Use when user asks about onion architecture, 洋葱架构, Jeffrey Palermo, concentric architecture, or needs layered domain isolation.
Apply Robert C. Martin-inspired architecture rules when separating business policy from frameworks, databases, UI, or infrastructure details.
SOLID and IoC design review. Use when the user asks to check SOLID, judge the design quality of a class or namespace, or when another skill needs a design review of the code it touched.
