[Pragmatic DDD Architecture] Guide for creating DDD Entities and Aggregates. Use when defining new domain entities with business rules, private state, and getters. Covers entity instantiation via objects, integration with Value Objects, and the rule against using setters.
[Pragmatic DDD Architecture] Guide for internationalization. Use when adding or editing translations in any component, page, or layout — also when wrapping a subtree in LocaleProvider, reading the active locale in a new component, building or modifying a locale switcher, or touching any file that calls determineLocale() or useLocale(). Covers the custom library-free implementation, Translations co-location, Server vs Client locale access patterns, and setLocaleAction.
Language-agnostic SOLID principles and DDD tactical patterns. Trigger: Always loaded for non-documentation code changes via sdd-apply.
Initialize CleanDDD dotnet projects (using netcorepal-web template); Used for creating new projects or quickly setting up solutions for client demos, can directly call dotnet new or wrapper scripts
Provides comprehensive guidance for DDD in microservices including bounded contexts, service boundaries, event-driven architecture, and microservice patterns. Use when the user asks about DDD microservices, needs to design microservices with DDD, or implement microservice architectures.
Use when reviewing a Ruby on Rails app for Domain-Driven Design boundaries, bounded contexts, language leakage, cross-context orchestration, or unclear ownership. Covers context mapping, leakage detection, and smallest credible boundary improvements.
[Pragmatic DDD Architecture] Guide for creating tests. Use when creating unit tests, integration tests, or understanding test conventions. Covers our tightly coupled stack: Vitest (unit, integration, ui projects), file naming, transactional database integration tests (txTest) with testcontainers/node-postgres/drizzle, mock patterns (createMock*RepoWithAssertions), and neverthrow Result assertions.
[Pragmatic DDD Architecture] Guide for creating DDD Value Objects (VOs). Use when defining a new Value Object in a domain layer. Covers immutability patterns, private constructors, random/from builders, Railway-oriented error handling via neverthrow Result, TypeScript branded error types, and co-locating errors within the VO file.
Scaffold an aggregate root with entity, value objects, repository interface, domain events, and test stubs
Domain-Driven Design patterns. Bounded contexts, aggregates, entities, value objects, domain events, repositories, and application services. Strategic and tactical DDD for complex business domains. USE WHEN: user mentions "DDD", "Domain-Driven Design", "bounded context", "aggregate", "value object", "domain event", "ubiquitous language", "aggregate root", "domain service" DO NOT USE FOR: database schema design - use database skills; CQRS/Event Sourcing specifics - use `event-sourcing-cqrs`
Create and manage a DDD bounded context with standard directory structure
Design DDD strategic artifacts including subdomains, bounded contexts, and ubiquitous language for complex business domains.
