Everyone's talking about loop engineering, but most people don't understand why and how it works. Most people don't realize that developers are using at the ship features eight time faster, and it's not because they can code more. They stop prompting their AI and are using loop system in order to prompt for them.

Here's how it works right now. When you use a coding agent, you type in a prompt and then read the output, and you type the next prompt. You're basically waiting at every step in our huge bottleneck.

Loop engineering means you build the system that finds the work, hands it to an agent, checks the result with the real test, records what happened, and decides the next move on its own. You design it once in, the system, prompts the agent from that point forward. But you need four things in place before you build one.

The task has to repeat at least weekly. You need an automated check that can fail bad work without you being in the room. You need a state file so that runs resume instead of restarting.

And you need a hard stop so that the loop does not burn tokens forever. Then the loop system is built with five pieces. An automation that fires a loop from a scheduler event.

A skill file that stores the project context so the agent does not start from zero at every cycle. A state file that records what the loop did. So that the next run picks off where the last one left off.

Connectors to MCP that let the loop open. PRs they tickets and pay you on Slack and sub agents that split the writing from the checking. Because a model that grades its own work will always think that it's correct.

You can start today with building a simple loop. The I failure triage is the best first loop every night. It scans your test failures, classifies each one, draft fixes for the easy on

a simple loop. The I failure triage is the best first loop every night. It scans your test failures, classifies each one, draft fixes for the easy ones, and escalates the rest to you.

And here are the two traps that burn most people. A loop without a real gate is just an agent agreeing with itself on repeat. And the faster the loop ships code that you did not write, the bigger the gap between what your repo has and what you actually understand.

I created a complete 10-step roadmap to Learning Loop Engineering. If you want it, just like the video and comment step, and I'll send it to you. For advice on making money and running your business with tech and AI.
