Adversarial code review costs 140% more for 7.5% quality gain, per benchmark
vikvang1 · x · 2026-11-06
A developer benchmarked Warp's factory to test whether adversarial code review is worth enabling.
- On his task set, it increased cost by 140% while improving quality only 7.5% — so probably not worth it, except possibly for very important changes (many caveats; details in the video).
- The author stresses the takeaway isn't the number itself but the method: set up a measurable benchmark pipeline and decide with data instead of vibes.
The real value is the practice: any AI coding tool config should be benchmarked before you flip the switch.
