Root Cause Tracing

When a bug appears deep inside your code, you might be tempted to fix the error right where it shows up. That only treats the symptom, not the real problem. This skill helps you trace backward through the sequence of function calls to find the original trigger. You start at the error and follow the chain back until you discover where the bad data or wrong behavior first started.

For example, if a git init fails in the wrong folder, you look at what code called it, then what called that code, and keep going. You might find a test that passed an empty string or a variable that was accessed too early. Fixing that root cause prevents the error from happening again.

You can also add temporary debug output like printing a stack trace to see exactly which test or function triggered the problem. This method works well when a bug only appears during long test runs or complex workflows.
