“Loop engineering” is having a moment.

Peter Steinberger, the creator of OpenClaw, told a few million people to stop prompting coding agents and start designing the loops that prompt them. Boris Cherny, who created Claude Code, says he no longer prompts Claude directly. Loops prompt Claude, and his job is to write the loops.

Then the pattern got a name, and the hot takes followed 😱

The basic idea is: instead of guiding a coding agent step by step, define a “loop” that lets it keep working until the task satisfies some “done” condition while you sleep, eat, and live the good life. The loop keeps the pesky agent accountable and on track as it builds your empire. Win-win!

With a bit of patience, you could set up teams of agents continuously building, reviewing, deploying, and repairing software while humans occasionally adjust the machinery.
