As coding agents write more of our software, token efficiency becomes part of developer experience. The framework influences the time and effort agents spend, how well they can verify their work, and the performance and user experience of the applications they build.
This talk shares how we’re using evals on the Next.js team to measure and improve agent success. We’ll look at what we’re learning, how framework features and automated workflows support that work, and what that means for developers building with agents.
This talk has been presented at AI Coding Summit Berlin, check out the latest edition of this Tech Conference.
