Identify dead code to delete during refactoring by evaluating the end-state codebase size and prioritizing deletions that reduce complexity without sacrificing required behavior. This approach targets obsolete code remaining after feature rewrites.

Codebase entropy reduction in software architecture is the practice of minimizing total code by prioritizing deletion over addition. It focuses on end-state measurement to ensure the final codebase is as small as possible while maintaining functionality.

Measure the end-state of a codebase after removing dead code by evaluating the final codebase size rather than the effort required to reach it. This ensures the reduction effectively lowers complexity and eliminates unnecessary components.

Code review checklists can reduce codebase complexity by applying decision discipline to prioritize deletions. They help identify unnecessary code, record the rationale for safe reductions, and enforce end-state minimality across software projects.

The best way to safely remove obsolete code after a feature rewrite is to prioritize deletions that reduce complexity and record the rationale guiding the reduction. This ensures functionality remains intact while minimizing the final codebase.

Prioritize deleting code over adding new features when aiming to reduce overall codebase entropy. Apply this during design reviews and refactoring to identify deletions that minimize the end-state without sacrificing required behavior.
