We've been running this system internally across tens of thousands of merge requests. It approves clean code, flags real bugs with impressive accuracy, and actively blocks merges when it finds genuine, serious problems or security vulnerabilities.

Cloudflare sells AI or agent tools or services, so it has a reason to publish flattering numbers about AI. The passage stays in the archive; read it with that in mind.
Checked against the source by a first reader, then confirmed independently by a second reader who fetched the source without seeing the first reader's notes (Independent review agent (Claude Sonnet), blind second pass from passage text and citation only, no repository access, 2026-11-04).
Verbatim match in the introduction. Straight vs curly apostrophe is the only difference. Author is Ryan Skidmore.

The bias is explicitly toward approval, meaning a single warning in an otherwise clean MR still gets approved_with_comments rather than a block.

On the cost side, the average review costs $1.19 and the median is $0.98. The distribution has a long tail of expensive reviews – massive refactors that trigger full-tier orchestration. The P99 review costs $4.45, which means 99% of reviews come in under five dollars.

In the first 30 days, the system completed 131,246 review runs across 48,095 merge requests in 5,169 repositories. The average merge request gets reviewed 2.7 times (the initial review, plus re-reviews as the engineer pushes fixes), and the median review completes in 3 minutes and 39 seconds.

That is fast enough that most engineers see the review comment before they have finished context-switching to another task. The metric we’re the proudest about, though, is that engineers have only needed to “break glass” 288 times (0.6% of merge requests).

Today, when an engineer at Cloudflare opens a merge request, it gets an initial pass from a coordinated smörgåsbord of AI agents. Rather than relying on one model with a massive, generic prompt, we launch up to seven specialised reviewers covering security, performance, code quality, documentation, release management, and compliance with our internal Engineering Codex. These specialists are managed by a coordinator agent that deduplicates their findings, judges the actual severity of the issues, and posts a single structured review comment.
