Apply DDD tactical patterns in code using entities, value objects, aggregates, repositories, and domain events with explicit invariants.
Immutable value objects for domain values. Use when working with domain values, immutable objects, or when user mentions value objects, immutable values, domain values, money objects, coordinate objects.
Clean Architecture, Hexagonal Architecture (Ports & Adapters), and Domain-Driven Design fundamentals. Layer boundaries, dependency rules, and tactical patterns for maintainable systems.
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`
Guides FastAPI backend design using Domain-Driven Design (DDD) and Onion Architecture in Python. Use when structuring a FastAPI app (routes/handlers, Pydantic schemas, Depends-based DI), modeling domain Entities/Value Objects, defining repository interfaces, implementing SQLAlchemy infrastructure adapters, or writing use cases, based on the dddpy reference.
Identifies domain modules, ownership boundaries, dependencies, and interfaces using Domain-Driven Design principles. Provides domain maps, bounded contexts, refactor recommendations. Use for "DDD", "domain modeling", "bounded contexts", or "service boundaries".
Map relationships between bounded contexts and define integration contracts using DDD context mapping patterns.
Scaffold and create a Modular Monolithic Architecture project. Use when the user wants to create a new modular monolith, restructure a monolith into modules, design module boundaries, or set up a project following modular monolith best practices. Supports multiple languages and frameworks.
Use when implementing features with test-driven development, writing tests before code, building domain-rich business logic, or following hexagonal architecture
[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.
This skill analyzes code for design quality improvements across 8 dimensions: Naming, Object Calisthenics, Coupling & Cohesion, Immutability, Domain Integrity, Type System, Simplicity, and Performance. Ensures rigorous, evidence-based analysis by: (1) Understanding code flow first via implementation-analysis protocol, (2) Systematically evaluating each dimension with specific criteria, (3) Providing actionable findings with file:line references. Triggers when users request: code analysis, design review, refactoring opportunities, code quality assessment, architecture evaluation.
Scaffold an aggregate root with entity, value objects, repository interface, domain events, and test stubs
