SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pydantic.

What problem does it solve?

Event modeling provides a structured, collaborative way to capture system behavior as narratives of events, commands, and read models, reducing miscommunication and rework.

Core Features & Use Cases

  • Model a system as a timeline of interfaces, commands, events, read models, and automations.
  • Visualize architecture via SVG diagrams and GWT-like test-style specifications.
  • Use for documenting existing systems, designing new features, and aligning stakeholders.

Quick Start

Capture the system's events and commands to generate a shareable event model and render the diagram.

FAQPage Schema
What is event modeling for software architecture?

Event modeling captures system behavior as a left-to-right timeline of interfaces, commands, events, and read models. It provides a structured narrative that reduces miscommunication and rework when documenting existing systems or designing new features.

How do I generate SVG diagrams from event timelines?

You generate SVG diagrams by capturing your system's events and commands into a structured schema with annotations. The tool validates inputs and renders the diagram to visualize chapters, slices, and interactions automatically.

Does event modeling work for Domain-Driven Design and read models?

Yes, event modeling works for Domain-Driven Design by structuring read models, commands, and events into a visual timeline. It clarifies workflows for engineers, product teams, and stakeholders using GWT-like test-style specifications.

Do I need pydantic to model systems with event timelines?

Yes, you need pydantic installed because the tool uses it to enforce a structured schema with annotations and validate inputs. This dependency ensures your system timeline data is strictly typed.

Can I use event modeling to document existing system behavior?

Yes, you can use event modeling to document existing system behavior by capturing current workflows as timelines. It translates existing interfaces, commands, and events into shareable SVG diagrams and test-style specifications.

What are the limitations of event modeling for new feature design?

Event modeling requires strict adherence to its structured schema with annotations. Users must decompose features into exact timeline components, which may limit flexibility for highly unstructured or non-event-driven workflows.
