Lauren Tan proposes "time to rewrite" as a heuristic for agent-readiness
AILauren Tan (@poteto) proposes "time to (fully automated, hands-off) rewrite" (TTR) as a rough thought-experiment heuristic for how well a codebase is set up for agents. She suggests asking how long a single engineer would need to rewrite the code in another language, framework, or architecture, since the answer surfaces gaps like missing verification that agents can use to confirm user-visible behavior matches. The post also raises questions about whether a rewrite would improve, maintain, or regress performance and maintainability over time.
