SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill addresses the common failure of domain models to enforce business invariants, preventing the creation of invalid objects and ensuring that state transitions are always atomic, testable, and documented.

Core Features & Use Cases

Invariant Enforcement: Implements the failing-constructor pattern to ensure no object can exist in an invalid state.
Domain-Driven Design: Provides standards for Value Objects, Domain Events, and Aggregate Roots that are pure, framework-agnostic, and highly testable.
Use Case: When building a complex backend service, use this skill to define your Aggregate Roots and Value Objects so that business rules are enforced at the type level, making illegal states unrepresentable.

Quick Start

Use the go-domain-model skill to generate a new domain aggregate with failing constructors and invariant-enforcing unit tests for the specified business entity.

FAQPage Schema

How do I enforce business invariants in a Go backend service?▼

To enforce business invariants in a Go backend, you implement the failing-constructor pattern to prevent the creation of invalid objects, ensuring state transitions remain atomic, testable, and documented at the type level.

What is the best way to structure Domain-Driven Design aggregates in Go?▼

Structuring Domain-Driven Design aggregates in Go requires using pointer-receiver method sets for aggregate roots and immutable value objects, ensuring your domain models remain pure and framework-agnostic.

How do I generate an aggregate root with invariant-enforcing unit tests in Go?▼

You generate a Go aggregate root by applying tactical DDD patterns, utilizing table-driven unit testing for all mutation paths to verify that business rules are enforced and illegal states are unrepresentable.

When do I need domain events in my Go domain model?▼

You need domain events in your Go domain model when complex business rules require atomic event emission alongside strict state validation, allowing state transitions to be documented and testable.

Can I use standard Go structs for complex business rules without domain purity?▼

Using standard Go structs without domain purity risks failing to enforce business invariants. To make illegal states unrepresentable, you must use immutable value objects and failing constructors rather than plain structs.
