# Systematic Debug

> Four-phase debugging framework that finds root causes before attempting fixes. Use when investigating errors, debugging failures, fixing bugs, analyzing test failures, diagnosing unexpected behavior, examining stack traces, or when the user says "it's broken", "this doesn't work", or "why is this failing".
