AI Really Fix Production Bug! | Senior Engineer Debugs a real GitHub Issue with Claude & Antigravity

📌 Links discussed:

Docling Issue #2800 (https://github.com/docling-project/do...)

----

Can AI coding assistants really fix production bugs — or are they just fancy autocomplete tools?

In this video, I take a real GitHub issue from a production open-source project (Docling) — already reported by users and fixed by maintainers — and walk through how a senior backend engineer actually uses AI to debug it.

This is not a toy example.
No contrived demo.
No hand-wavy “AI magic”.

What you’ll see in this video:

How senior engineers read and classify bugs before touching AI

Using Claude inside VS Code to identify architectural fault lines

Turning AI into a reasoning partner, not a code generator

Finding the real root cause behind a user-reported defect

Comparing Claude’s fix with the actual merged PR

Re-running the same analysis using Google Antigravity

Why most “AI can code” demos miss the real point
