Break down complex code blocks and expressions into simpler, more readable components. Complex boolean logic, nested conditions, and multi-operation lines should be refactored for clarity. Key practices: 1. Split complex boolean expressions into named variables or helper methods 2. Break long one-liners into multiple lines 3. Prefer positive conditions over negative ones 4. Use early returns to reduce nesting Example - Before: ```ruby return unless artifacts.reject do |k| k.is_a?(::Cask::Artifact::Font) end.empty? ``` After: ```ruby return if artifacts.all?(::Cask::Artifact::Font) ``` Or when dealing with complex conditions: Before: ```ruby print_stderr = !(verbose && show_info).nil? ``` After: ```ruby print_stderr = if verbose && show_info true else false end ``` This approach makes code easier to read, understand, and maintain while reducing the cognitive load on reviewers and future maintainers.
