implementation-principles

What problem does it solve?

Code-level principles (Fail Fast, Single Source of Truth, Ports & Adapters enforcement) provide guardrails that improve consistency, reduce bugs, and accelerate safe feature development; this Skill auto-loads when writing new functions or modules and guides input validation, guard clauses, and avoidance of defensive boilerplate.

Core Features & Use Cases

• Fail Fast: validate inputs at the boundary and fail loudly with clear errors.
• Single Source of Truth: centralize variant/config definitions and derive downstream types from a single source.
• Ports & Adapters enforcement: domain logic operates on ports, while infrastructure is implemented as adapters.
• Use Case: apply these principles whenever adding a new feature to ensure clean interfaces and testability.

Quick Start

Enable the principle set in your project to automatically enforce best practices during feature development.
