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.
