1. Blast Radius Replaces Diff Size as Agentic AI Reshapes Code Review

InfoQ. Rootly dropped its small pull request rule after finding that AI agents ship complete features rather than incremental changes, making line-count review an unhelpful signal. The team moved the safety boundary from merge-time review to production-time progressive rollout, where an internal AI reviewer produces structured risk assessments and features ship behind feature flags that are enabled incrementally. The pattern reframes review around a change’s blast radius and staged exposure rather than the size of its diff, matching how agentic systems actually generate code. Source
