When should I use the Event Storming skill?

Use it when domain requirements are unclear, when you are struggling to name domain entities, or when you need to organize the artifacts of an Event Sourcing system.

Is this skill suitable for CQRS architectures?

Yes, it is specifically designed to help define the commands, events, and read models necessary for a clean Command Query Responsibility Segregation (CQRS) implementation.

What is Event Storming in the context of this skill?

Event Storming is a modeling technique used to identify business events and processes. This skill automates the identification of those events, commands, and aggregates within your code environment.

How does this skill handle naming conventions?

It enforces strict rules, such as expressing events as past-tense verbs (e.g., 'OrderCreated') and ensuring they correspond directly to the command that triggered them.

Facilitates the extraction, naming, and reviewing of domain events, commands, and aggregates using Event Storming techniques.

The Event Storming Modeler skill empowers Claude to assist in complex Domain-Driven Design (DDD) tasks by focusing on business events as the core of system logic. It provides a structured framework for identifying domain events in past-tense notation, mapping them to specific commands, and defining clear aggregate boundaries. This skill is particularly useful when requirements are ambiguous or when building systems based on CQRS and Event Sourcing architectures, ensuring consistency between business actions and state changes through rigorous naming conventions and relationship mapping.
