Announce at start: "Following the debugging skill to find root cause before fixing."
NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST
If you have not completed steps 1-4 below, you cannot propose fixes. Symptom fixes are failure.
Collect the full picture before forming any hypothesis.
Create a minimal environment where the bug consistently occurs.
Narrow down to the exact component or function.
git log, git bisect)Identify the root cause — not just the symptom.
Implement the minimal correction needed.
Confirm the fix is correct and complete.
| Signal | Action |
|---|---|
| Tempted to "just try something" | Go back to step 1 |
| Fix didn't work | You don't have root cause — go back to step 4 |
| Multiple fixes attempted | You're guessing — go back to step 3 |
| Under time pressure | Slow down — systematic is faster than thrashing |
| Issue seems simple | Simple bugs have root causes too — follow the process |
| When | Invoke |
|---|---|
| Bug fix requires multi-file changes | refactoring |
| Need to write regression test | testing |
| Fix touches security-sensitive code | secure-coding |
| Ready to submit the fix | pr-writing |
