kata-domain-model

What problem does it solve?

It helps you discover, structure, and persist a Domain-Driven Design (DDD) domain model for a specific feature or module, turning ambiguous business knowledge into a complete canonical set of entity and event documents.

Core Features & Use Cases

• Guided domain discovery: transforms directives and open questions into a domain description, business rules, and system boundaries.
• Ubiquitous language and context mapping: defines consistent terminology and maps bounded contexts using a context map pattern.
• Canonical persistence workflow: produces distributed outputs for entity catalog files and integration events, delegating actual persistence to other katas/tools.

Example Use Case

Model a bounded context for "scheduled transfers" where accountants schedule transfers, supervisors approve them, and a scheduler triggers execution on the scheduled date, including lifecycle states, invariants, use cases, and CloudEvents integration event types.

Quick Start

Ask the AI to run the Domain Modeling (DDD) workflow for your module by providing the bounded context name, domain description, and CloudEvents module, and answer any missing questions about actors, boundaries, and triggers.
