Software Design Principles

What problem does it solve?

This Skill codifies core software design principles to produce maintainable, well-structured code.

Core Features & Use Cases

• Object calisthenics and disciplined naming: Enforce clarity and domain-focused naming to improve readability and reduce unnecessary comments.
• Dependency inversion and testability: Encourage dependency injection to simplify testing and future changes.
• Fail-fast error handling: Promote explicit validation and early failure to catch issues at the source.
• Type-driven design and immutability: Favor strong types and immutable patterns to prevent illegal states and side effects.
• Use during refactoring and design reviews: Apply these principles when restructuring code or evaluating architecture.

Quick Start

Replace generic names such as data, utils, or helpers with domain-specific terms during code reviews. Introduce explicit interfaces for dependencies and apply dependency injection. Add explicit validations and fail-fast errors to surface problems at the source.
