Recent 2026 evidence shows AI code review tools are excellent first-pass reviewers, but they still do not replace human reviewers for architecture, intent, risk, mentoring, and final acceptance.
2026 evidence from Faros AI, SonarSource, The Pragmatic Engineer, CodeRabbit, Harness, and academic research shows AI coding raises throughput alongside bugs, review time, incidents, and maintenance load. Here is what turns that speed into safe delivery: repository rules, feature flags, and lifecycle memory.
