From Prompt Engineering to Loop Engineering
The default way we've used coding agents is conversational: you ask, read the reply, ask again. Your attention is what keeps the whole process moving, and it's the sole bottleneck. That model is starting to break down at scale. What's emerging instead is a shift in where the engineering effort goes: away from crafting individual prompts, toward building a system that surfaces the work, dispatches it to agents, validates the output, tracks state, and picks (or invents) the next task on its own. You author that system once. After that, it's the system doing the prompting, not you.

This talk walks through how such a loop is actually assembled, so you can build your own today.
