SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps you define and document your domain's ubiquitous language in a clear, descriptive format, moving away from technical ERDs towards human-readable specifications.

Core Features & Use Cases

  • Ubiquitous Language Definition: Extracts and formalizes domain terms, relationships, constraints, and lifecycles.
  • Descriptive Specifications: Generates domain-model.md files that are easily understood by all stakeholders.
  • Use Case: When planning a new feature, use this Skill to ensure all team members share a common understanding of the domain's core concepts and rules before any code is written.

Quick Start

Use the model-domain skill to generate the domain model for the 'users' domain.

FAQPage Schema
How do I document domain-driven design ubiquitous language for stakeholders?▼

Document ubiquitous language by generating a descriptive domain model specification in Markdown, focusing on terms, relationship rules, constraints, and entity lifecycles. This serves as a human-readable alternative to technical ERDs.

What is the best way to define entity lifecycles and constraints in domain modeling?▼

Define entity lifecycles and constraints by extracting terms and generating relationship rules from session data. This produces a formalized domain model specification detailing the ubiquitous language of your system.

Can I generate a domain model specification without creating technical ERDs?▼

Yes, you can generate a domain model specification without ERDs. This produces a Markdown file detailing domain terms, relationship rules, constraints, and lifecycles, providing a human-readable format for all stakeholders.

When do I need a ubiquitous language specification for domain-driven design?▼

You need a ubiquitous language specification when planning new features to ensure all team members share a common understanding of the domain's core concepts and rules before any code is written.

Does domain modeling in Markdown work for defining relationship rules and constraints?▼

Markdown domain modeling works for defining relationship rules and constraints. It extracts terms and formalizes constraints based on provided session data, outputting a comprehensive domain model specification.
