Background & analysis
On October 17, 2026, an article published on Juejin described how the Claude Code team is handling code review as AI coding tools push pull request volume higher. According to the article, those tools have doubled the number of PRs, making manual review a new bottleneck.
The team's approach, as the article describes it, is to move code review away from being a final gate before merging and turn it into a continuous check within the development workflow. This involves JIT planning, AI preprocessing, and a reworked division of labor between humans and AI. The report does not specify the exact numbers behind the doubling of PRs, the period over which it occurred, or how well these practices have worked in practice.
