“Most routing systems focus on accuracy and cost, but they often miss whether agents are actually different or if the routing stays steady when inputs change slightly. This study shows that a few well-chosen agents cover most of the variety needed, and prompted routers are more stable than KNN methods.”

generate the list of files to migrate, fan out one scripted agent per file with scoped permissions, test on two or three files, then run at scale. Orosz's field notes cover the rest.

“Now do the math. The run cost about $165,000 in tokens. That sounds like a lot until you look at the other options. Sumner thinks a manual rewrite would take a small team an entire year. No one would ever sign off on that. Anthropic's best-practices guide shows a small version of Sumner's playbook.”
