SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill helps teams design complex systems by producing modular, testable event slices described in business language, reducing ambiguity and context switching.

Core Features & Use Cases

  • Three slice types: STATE_CHANGE, STATE_VIEW, AUTOMATION, each with their own rules.
  • Guided modeling process: from domain understanding to executable specifications.
  • Output-ready artifacts: a high-level event model and per-slice details, plus references guidance.

Quick Start

  • Open Claude Code and run the event-modeling workflow to generate a high-level model.
  • Define slices and relationships, then export to your preferred docs.

FAQPage Schema
What is event modeling and how does it map complex business behavior?

Event modeling maps complex business behavior into modular, testable slices. It defines STATE_CHANGE, STATE_VIEW, and AUTOMATION slices to document relationships and rules, reducing ambiguity and context switching for product and engineering teams.

How do I design an event model with testable slices?

To design an event model, define slices using STATE_CHANGE, STATE_VIEW, and AUTOMATION rules. You generate a high-level event model document and per-slice specifications with structured Markdown frontmatter guidance.

Does event modeling work for domain-driven design specifications?

Yes, event modeling works for domain-driven design specifications by translating business language into executable specifications. It captures domain understanding and outputs modular slices documented with structured Markdown references.

What is the best way to document state changes and state views?

The best way to document state changes and views is creating STATE_CHANGE and STATE_VIEW slices. This event modeling process outputs a high-level event model document plus per-slice specifications using Markdown frontmatter.

Can I use event modeling for product and engineering team processes?

Yes, product and engineering teams use event modeling to design complex systems. It applies to modeling processes by defining STATE_CHANGE, STATE_VIEW, and AUTOMATION slices and documenting their relationships and rules.
