systematic-debugging

Systematic debugging follows a four-phase framework: establish reproducibility, gather evidence about all system layers, form hypotheses from facts, then test and fix. This prevents wasting time on symptom fixes and ensures you understand the root cause before making changes.

Applying fixes without investigation often targets symptoms rather than root causes. Systematic debugging enforces a mandatory investigation phase first, catching architectural issues and hidden failure points across all components—secrets, workflows, builds, signing—that casual fixes miss.

The systematic debugging framework includes built-in defenses against rationalization and pressure-driven shortcuts. It guides you through structured evidence gathering and staged implementation rules, ensuring you stay grounded in facts even when emergencies push for quick fixes.

Yes. The four-phase process applies to any technical issue—test failures, production incidents, integration problems, performance degradation, and build failures—because it focuses on investigation method, not failure type.

When multiple attempted fixes fail or each fix creates new issues, systematic debugging reveals whether the root cause is a fundamental design flaw. The framework identifies architectural problems by tracing failures across all system layers rather than treating each symptom in isolation.
