Ruby Conventions Reference

description: >-
  Worked GOOD/BAD examples for Ruby style and OOP conventions — naming, idioms, safe
  navigation, freeze, SRP, dependency injection, Tell-Don't-Ask, Law of Demeter, duck
  typing, composition over inheritance.
  CONSULT when you need an idiomatic Ruby example or are unsure how a style/OOP rule looks
  in code. Reference loaded on demand — the always-apply rules themselves live in the
  `ruby-style` and `ruby-oop` rules.

# Ruby conventions — worked examples

Companion to the `ruby-style` and `ruby-oop` rules. Read the reference file (in this skill's
folder) for the topic you need:

- **Style** — naming, quoting, safe navigation, `Time.current`, freeze, idiomatic Ruby →
  `references/style.md`
- **OOP** — SRP, dependency injection, Tell-Don't-Ask, Law of Demeter, duck typing,
  Open/Closed, composition over inheritance → `references/oop.md`
