code-refactoring

Refactor code while preserving behavior, improving clarity, and reducing complexity. Before (long function) : After (method extraction) : Before (duplication) : After (extract common logic) : Before (long if-else) : After (polymorphism) : Before (many parameters) : After (grouped into object) : Single Responsibility : Fully understand current behavior before refactoring: Cause : Behavior change occurred Solution : Revert and isolate the change, then retry Cause : Multiple responsibilities mixed in one function Solution : Extract into smaller units with clear boundaries Cause : Inefficient abstraction introduced Solution : Profile and optimize the hot path #refactoring #code-quality #DRY #SOLID #design-patterns #clean-code - Covers five core refactoring patterns: Extract Method, DRY principle removal, conditional-to-polymorphism conversion, parameter object introduction, and SOLID principle application - Includes behavior validation workflow with pre-refactoring analysis, post-refactoring testing (unit, type, lint, snapshot), and change documentation - Provides refactoring checklist covering function length, parameter count, nesting depth, magic numbers, and self-documentation - Enforces mandatory constraints: write tests first, change one thing at a time, preserve all functional behavior - Supports multi-agent workflows with role-based verification across orchestration,...
