What is Loop Engineering? (Why Prompt Engineering is Dead)

Loop engineering is not a buzzword. It is the exact blueprint for how production AI systems are being built in 2026. Granola is the AI meeting notepad I use to capture conversations, generate clean summaries, extract action items, and draft follow-ups across Google Meet, Zoom, Slack, WhatsApp, and more.

We moved from prompt engineering to context engineering, and now, the industry has arrived at loop engineering. Because modern models can write their own prompts and retrieve their own context, the real scarce skill is designing the loop the agent runs inside.

We cover the hidden trap of context rot, why setting explicit stopping conditions is the number one failure point, and the critical concept of "harness engineering." I also introduce the MINT framework (Minimal Intelligence, Necessary Tools) to help you build reliable systems without drowning in complexity, and we map out exactly how Andrew Ng's three nested loops fit into production architectures.
