Reproduce +Confirm the bug is reproducible before doing anything else. Run the failing test, command, or request. If you cannot reproduce it, say so immediately — do not guess at a fix. + +### 2.

If you have multiple hypotheses, rank them by likelihood. + +### 4. Verify the hypothesis +Before editing anything, verify your hypothesis is correct. Add a targeted log, run a narrowed test, or trace the data flow. A fix based on a wrong hypothesis creates a second bug. + +### 5. Apply a minimal fix +Fix only the root cause. Do not: +- Refactor surrounding code +- Add unrelated error handling +- Improve naming or style +- Change behavior beyond what's needed to fix the bug + +If the fix requires touching more than 2–3 lines, explain why the scope is necessary. + +### 6. Verify the fix +Run the test or repro case again. Confirm the bug is gone.

If you notice other issues while debugging, list them in your output but do not fix them.
