SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The Skill documents domain model knowledge for the project to provide clear context about entities, relationships, and business rules.

Core Features & Use Cases

  • Entities: Core business objects and their purposes
  • Relationships: How entities relate (1:1, 1:N, M:N)
  • Business Rules: Validation constraints and invariants
  • Field Descriptions: What each field means in business terms
  • Enums/Value Objects: Status types, categories, codes

Quick Start

Document your domain model using the provided template to capture entities, relationships, and rules for consistent downstream usage.

FAQPage Schema
How do I document domain models for AI agents to understand business logic?

To document domain models for AI agents, you use a structured template to define entities, relationships, business rules, and field descriptions, ensuring consistent documentation and enabling automated reasoning for design and validation.

What is the best way to define business rules and entity relationships in a data model?

The best way to define business rules and entity relationships in a data model is by applying a structured template that captures core business objects, their 1:1, 1:N, and M:N relationships, validation constraints, and invariants for clear contextual knowledge.

How do I structure a domain model template to capture entities and value objects?

You structure a domain model template by organizing it into sections for core entities, relationship types, business rules, field descriptions, and enums or value objects like status types, categories, and codes to provide consistent downstream usage.

When do I need to document a domain model for my software project?

You need to document a domain model when modeling business domains to define entities, relationships, and business rules, providing clear context about validation constraints and invariants for design, validation, and implementation phases.

Can I use a domain model template for validation constraints and invariants?

Yes, you can use a domain model template for validation constraints and invariants by capturing business rules within the structured documentation, which enforces consistent definitions and enables automated reasoning for your software implementation.

Why does my AI agent lack contextual knowledge about my business domain entities?

Your AI agent lacks contextual knowledge because domain model knowledge is not documented, making it difficult to provide clear context about entities, relationships, and business rules for automated reasoning and consistent downstream usage.
