Google Developers released a methodology to measure how AI coding agents waste time on outdated code comments. They analyzed hundreds of millions of agent steps to show that old TODOs referencing resolved bugs cause significant detours and incorrect logic. The study uses multi-way fixed-effects regression to prove this overhead is statistically significant across developers and models.
This is worth reading if you are scaling agent-based coding, as it highlights a hidden tax on team velocity. The catch is that the proposed fix, an automated cleaner for dead references, is not a standalone open-source tool but part of Google's internal infrastructure. You will need to build your own remediation pipeline to apply these findings to your own codebase.
