Simplicity Principles

About

The Simplicity Principles skill empowers Claude to design and implement software solutions that prioritize readability and necessity over complexity. By applying the 'Keep It Simple, Stupid' (KISS) approach, avoiding premature features via 'You Aren't Gonna Need It' (YAGNI), and ensuring behavior aligns with the 'Principle of Least Astonishment' (POLA), this skill helps developers reduce cognitive load and technical debt. It provides specific patterns for Elixir and TypeScript, guiding Claude to avoid over-engineering and focus on direct, boring, yet robust implementations that are easy to test and debug.

Key Features

• Identifies over-engineered abstractions and suggests simpler alternatives
• Enforces KISS (Keep It Simple, Stupid) for readable, direct implementations
• Implements POLA (Principle of Least Astonishment) for predictable code behavior
• Provides domain-specific patterns for Elixir and TypeScript development
• 39 GitHub stars
• Applies YAGNI (You Aren't Gonna Need It) to prevent premature feature bloat

Use Cases

• Reviewing new feature requests to ensure only necessary code is added
• Refactoring complex legacy code into simpler, more maintainable functions
• Standardizing API behavior and naming conventions to meet developer expectations
