AI agentAn AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.Full definition → infrastructure needs a way to change without making every new technique a rebuilding project. In its conference talk, Box describes designing replaceable layers and using evaluations to decide whether a migration earns its cost. The speaker recounts withdrawing earlier architectural advice as better approaches emerged, including asking a team to reconsider work it had just finished.
The proposed discipline is to preserve flexibility while requiring evidence for each switch. Teams prepare for components to change, then compare alternatives on their actual tasks. That gives engineers a reason to migrate that is tied to their system's performance rather than the arrival of another paper.

AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
eval — A repeatable test for AI quality — a set of tasks plus scoring — used the way software teams use test suites, because model output is too variable to judge by eyeballing.
