AI DEBUGGING.
TRACE THE ACTUAL FAILURE.
Start with a failure that can be observed. Follow the path that produces it. Stop guessing when the evidence tells you where to look.
ONE CLICK.
TWO REQUESTS.
The network log shows two submissions for one user action.
- Inspect where the listener is registered.
- Check whether initialization runs more than once.
- Reproduce after a mount or navigation cycle.
Prove the repeated registration before changing the event handler.
A FIX SHOULD
CLOSE A LOOP.
Capture the failing condition. Make a focused change. Repeat the same check. Then look for the nearby behavior that could have regressed.
Do not replace a failing subsystem merely because a larger rewrite is easier to describe.
REPRODUCE
ISOLATE
PATCH
CHECK AGAIN
Turn a symptom into a testable explanation
Start with the exact input, observed output and conditions that reproduce the problem. A duplicate request, an unexpected response body and an empty value can look similar in a high-level error message but require different investigations.
Use the evidence to narrow the path before patching it. After a focused change, repeat the same failing case and inspect nearby behavior that might regress. The examples describe possible investigation steps, not diagnoses of a live application or verified fixes for your project.
