It helps you debug failures systematically by locating the underlying root cause before making any changes, so you stop whack-a-mole fixes that break again later.
Use investigate when you paste the error and reproduce steps, then ask: Investigate this failure and tell me the most likely root cause and the smallest verified fix.

Root cause investigation isolates the true source of a bug from its symptoms by forming testable hypotheses from errors and logs. It requires evidence confirmation before applying any fix, preventing recurring whack-a-mole patches.
Debugging intermittent failures and regressions requires deterministic reproduction to confirm or reject hypotheses. By applying targeted checks and re-running the reproduction path, you verify the exact failure source before changing code.
Fix verification uses controlled implementation by applying a minimal change once the root cause is confirmed. It then re-runs the reproduction path with a regression-verification mindset to ensure behavior is fixed without new issues.
Error triage handles troubleshooting configuration drift and unexpected errors by systematically isolating the underlying root cause. It transforms broken behavior into a specific, testable hypothesis about what is actually wrong.
Hypothesis testing for broken behavior requires deterministic reproduction and evidence confirmation before implementing fixes. Without controlled scope and a regression-verification mindset, changes may lack the evidence needed to truly resolve the issue.
