Usage Examples

Create Event Model

/event-modeling:event-modeling "order fulfillment process"
/event-modeling:event-modeling "user registration flow" depth=detailed

Design Saga Pattern

/event-modeling:saga-patterns "payment processing with inventory reservation"
/event-modeling:saga-patterns "multi-step approval workflow" style=orchestration

Event Sourcing Design

Invoke the event-sourcing-advisor agent to:
- Evaluate if event sourcing fits your use case
- Design event store schema
- Plan projection strategies
- Handle event versioning

Methodologies Covered

Event Modeling

Adam Dymitruk's visual approach with:

• Blue swimlanes (UI/commands)
• Orange events (state changes)
• Green read models (projections)
• Timeline-based flow

Event Storming

Beyond big picture:

• Process-level storming
• Design-level storming
• Software design mapping
• Bounded context discovery

CQRS/Event Sourcing

• Command/query separation
• Event store design
• Projection patterns
• Snapshotting strategies

Saga Patterns

• Orchestration (central coordinator)
• Choreography (distributed events)
• Compensating transactions
• Timeout and failure handling
