What's this about?
Baoyu asks a review agent to understand the PR's problem, design its own solution without reading the implementation, then inspect the code and compare the two approaches.
What exactly is “anchoring”?
Anchoring is the tendency to let the first solution seen narrow later thinking. Making the agent solve the problem independently creates a reference plan before the submitted code can bias it.
Why is this worth noting?
The prompt turns review from “find obvious defects in this diff” into a comparison between alternative designs. It still needs tests and human context, but it is a small reusable technique for stronger agent review.
