A practical take on what makes an AI code review benchmark trustworthy: use real-world PRs, define clear ground truth labels, measure precision/recall and noise, and ensure runs are reproducible with baselines. It frames evaluation around both detection quality and developer impact (time-to-review and merge latency), not just raw findings.
Good benchmarks prevent picking tools that look strong in demos but underperform on your code and workflows.
Measuring false positives and developer impact reduces review noise and protects velocity.
-
terminal
Replay a stratified sample of recent PRs through candidate tools and compute precision/recall and false-positive rate against human reviewer comments.
-
terminal
Pilot in CI with non-blocking checks and track time-to-first-review, merge latency, and developer acceptance of suggestions.
