Code Rot

ELI5 — The Vibe Check

Code rot is the slow decay of a codebase from neglect. Comments become lies. Dead code piles up. Conventions drift. Each tiny compromise is fine; together they make the code unreadable.

Real Talk

Code rot is the progressive deterioration of code quality through accumulated shortcuts, outdated comments, dead branches, inconsistent conventions, and drift from original design intent. Unlike bitrot (environmental change), code rot is human-caused. Prevention requires active maintenance, style enforcement, and periodic cleanup.
