Better tools made Copilot code review worse. Here’s how we actually improved it.

GitHub's Copilot code review initially worsened after switching to better-maintained, shared tools due to incorrect instructions. By rewriting the instructions to reflect a reviewer's workflow, they achieved a 20% lower average review cost while maintaining quality. The original instructions, optimized for general coding-assist purposes, led to unnecessary, broad searches and context gathering, whereas a revised approach prioritized targeted searches, batching, and focused code reads.
