SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Prevents Big Bang rewrites by guiding atomic refactoring through the Strangler Fig pattern.

Core Features & Use Cases

  • Atomic steps: extract methods, introduce parameter objects, replace conditional logic
  • Strangler Fig migration: route traffic gradually to new implementation
  • Use Case: Migrate an authentication module over time without downtime

Quick Start

Establish baseline tests, identify code smells, and apply one atomic refactoring at a time, using Strangler Fig approach to migrate to new implementation.
