Use when the user wants to create or update a DDD-style ubiquitous language glossary, define domain terms, resolve ambiguous terminology, harden naming, or write UBIQUITOUS_LANGUAGE.md from the current conversation and codebase context.
Scaffold an aggregate root with entity, value objects, repository interface, domain events, and test stubs
Validate domain boundaries -- detect cross-context import violations and aggregate invariant issues
Event sourcing patterns for storing state as a sequence of events. Use when implementing event-driven architectures, CQRS, audit trails, or building systems requiring full history reconstruction.
Implement Domain-Driven Design tactical patterns in C#/.NET. Use when building Entities, Value Objects, Aggregates, Domain Events, Repositories, or structuring a DDD solution. Framework-agnostic — covers pure domain modeling with modern C#.
Design, refactor, analyze, and review code by applying the principles and patterns of tactical domain-driven design. Triggers on: domain modeling, aggregate design, 'entity', 'value object', 'repository', 'bounded context', 'domain event', 'domain service', code touching domain/ directories, rich domain model discussions.
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`
Discovers business domains in a Swift codebase by tracing what users can DO — not by reading folder names or architecture docs. Maps each domain's vertical slice (Types → Config → Repo → Service → Runtime → UI), identifies providers (external SDK bridges), and separates cross-cutting concerns. Produces a domain map that drives all downstream decisions: folder structure, SPM targets, enforcement specs, migration plans. Use this skill whenever the user wants to understand their codebase domains, find what's cross-cutting vs domain-specific, restructure a Swift project, figure out where code belongs, or map a product's capabilities to architectural boundaries. Triggers on "what are my domains", "where does this belong", "map this codebase", "what's cross-cutting", "organize this project", "is this a domain or infra", "restructure this", "architecture review", or any request to understand the business domain structure of a Swift codebase.
Use when implementing features with test-driven development, writing tests before code, building domain-rich business logic, or following hexagonal architecture
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.
This skill should be used when implementing DDD tactical design patterns in Go, including Entities, Value Objects, Aggregates, Repositories, Domain Services, Domain Events, Factories, and Specifications.
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.
