Single-Agent vs. Multi-Agent Code Review: Why One AI Isn’t Enough

In the evolving landscape of software development, code review processes are increasingly strained by the surge in pull request (PR) volume, particularly following the adoption of AI-assisted coding. Traditional manual review methods, reliant on a small group of senior engineers, are becoming untenable as they struggle to manage the complexity of multi-repository changes and heightened security and compliance requirements. Qodo emerges as a solution by integrating AI code review agents into CI/CD workflows, automating the enforcement of standards and policies at merge time without eliminating the critical human judgment. These agents address various review concerns, such as security, dependency impacts, and compliance, by generating deterministic outcomes, thus relieving senior engineers of repetitive tasks and ensuring consistency across large teams. This approach transforms code review from a manual, subjective process into a scalable, infrastructure-like capability, enabling efficient handling of PRs while maintaining quality and governance across extensive codebases.
