What is the focus of the 'Ubiquitous Language' feature?

It helps synchronize terminology between domain experts and developers, ensuring that the code mirrors the business reality and reducing communication overhead.

Which programming paradigms does this support?

While it draws heavily from functional programming concepts like Railway-Oriented Programming, the principles are applicable to any language supporting strong typing or structured data.

Does it support visual documentation?

Yes, the skill can generate Mermaid, Graphviz/DOT, and ASCII diagrams to visualize domain entities, workflows, and state transitions.

How does this skill improve code reliability?

It leverages type-driven design to ensure that invalid business states are impossible to represent in your code, significantly reducing logic errors and edge-case bugs.

API 개발

Applies domain-driven and type-driven design principles to build robust business models and eliminate illegal states in software architecture.

This skill empowers developers to architect systems using advanced domain modeling techniques inspired by Rich Hickey's data-oriented design and Scott Wlaschin's functional type-driven approach. It helps identify domain inconsistencies, establishes a ubiquitous language across the codebase, and visualizes complex business logic using Mermaid or Graphviz. Whether you are refactoring legacy logic or designing a new service from scratch, this skill ensures your domain model remains pure, data-centric, and perfectly aligned with business requirements.
