# Skills

> Copyable reference implementations for common Ethereum patterns

Skills are copyable reference implementations you can use as-is or customize for your needs. Unlike traditional libraries, Skills live in your codebase—visible, debuggable, and fully customizable.

<Tip>
  New to Skills? Read the [Skills Philosophy](/concepts/skills) to understand why we use copyable implementations instead of library abstractions.
