SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Cross-aggregate consistency rules are needed to ensure domain events across multiple aggregates are coordinated to avoid conflicting outcomes.

Core Features & Use Cases

Implement inter-invariant patterns that span publisher and consumer aggregates via domain events.
Provide shared event classes, subscriptions, and command handling for Sagas and TCC workflows in a quizzes module.
Use this skill to model cross-aggregate policies such as ensuring a consumer's invariant holds after a publisher event.

Quick Start

Review the SKILL.md, implement the event subscription wiring, and add the required handlers, commands, and sagas following the examples in the repository.

FAQPage Schema

How do I enforce cross-aggregate consistency in microservices?▼

Cross-aggregate consistency is enforced by coordinating domain events between publisher and consumer aggregates to prevent conflicting outcomes. This approach uses inter-invariant patterns to ensure a consumer's invariant holds after a publisher event.

What is the best way to coordinate sagas and TCC workflows with domain events?▼

Coordinating sagas and TCC workflows with domain events requires shared event classes, subscriptions, and command handling. This implementation models cross-aggregate policies to track state and manage command flows across publisher and consumer aggregates.

Why do I need cross-aggregate invariants in event-driven architectures?▼

Cross-aggregate invariants are needed in event-driven architectures to ensure domain events across multiple aggregates are coordinated to avoid conflicting outcomes. They enforce policies such as ensuring a consumer's invariant holds after a publisher event.

How do I implement event subscriptions and command handlers for inter-invariant patterns?▼

Implementing inter-invariant patterns involves wiring event subscriptions and adding required handlers, commands, and sagas. You review the SKILL.md, implement the subscription wiring, and follow repository examples for the quizzes module.

Do I need specific dependencies to model cross-aggregate policies with sagas?▼

No specific dependencies are required to model cross-aggregate policies with sagas. The implementation relies on shared event classes and command flows within the module to coordinate event subscriptions and state tracking.
