Study Shows AI Coding Agents Add Code but Lengthen Review Times
Understand the story
A study shows that introducing AI coding agents significantly increases the code review burden in software development: average review time from pull request submission to merge increased by 49%, the share of pull requests requiring changes nearly doubled, comments per pull request increased by 35%, and the share of employees involved in code review rose by 14%. Overall, AI coding agents generate more code but result in less software actually merged, with significantly more time and effort spent on code review.
