> You no longer need to review the code. Or instruct the model at the level of files or functions. You can test behaviors instead. Maybe for a personal project but this doesn't work in a multi-dev environment with paying customers. In my experience, paying attention to architecture and the code itself results in a much more pliable application that can be evolved.
Counter argument... High velocity teams also observe production system telemetry and use error rates, tracing and more to maintain high SLAs for customers. They set a "budget" and use feature flagging to release risky code and roll back or roll forward based on metrics. So agentic coding can feed back on observed behaviors in production too.
