What is the primary benefit of the Event Modeling skill?

It provides a structured, visual framework for designing complex systems that ensures both technical and business stakeholders have a shared understanding of the timeline and state changes.

Can I use this for existing legacy systems?

Absolutely. It is an excellent tool for reverse-engineering existing processes to identify bottlenecks or for planning migrations from monoliths to event-driven architectures.

Does this skill support UI design integration?

Yes, it uses the 'Blue Lane' to map UI screens and wireframes as commands that trigger domain events, ensuring the user experience is baked into the architecture.

How are 'slices' used in this methodology?

Slices are vertical cross-sections of the model containing a specific command, its resulting event, and the updated read model, allowing for independent implementation and testing.

API Development

Implements Adam Dymitruk’s Event Modeling methodology to design event-driven systems using structured swimlanes and chronological timelines.

About

This skill empowers Claude to act as a system architect using the formal Event Modeling framework. It guides users through the entire design process—from brainstorming domain events and organizing them on a chronological timeline to defining commands, read models, and automated policies. By utilizing a documentation-first approach and the 'vertical slice' methodology, it ensures that complex software architectures are visually mapped, stakeholder-aligned, and ready for implementation as discrete, testable features that map directly to code.

Key Features

Chronological timeline mapping (Time flows left to right)
Vertical 'Slice' identification for independent feature implementation
Documentation-first patterns based on official eventmodeling.org standards
Standardized swimlane categorization for Commands, Events, and Read Models
Automated policy and business reaction mapping
12 GitHub stars

Use Cases

Creating implementation blueprints that bridge the gap between requirements and code
Visualizing business processes and state changes for non-technical stakeholders
Designing complex event-driven architectures and microservices
