❗️Prompt engineering is out

❗️Prompt engineering is out. Loop engineering is in. For the past two years, the AI skill everyone talked about was writing better prompts. Now, some of the people building the most advanced coding agents are saying that era is ending. The creator of OpenClaw⁠ summed it up in a viral post: “You no longer need to prompt coding agents. You need to design loops that prompt your agents.” A month earlier, Boris Cherny made a similar point. He said Claude has written essentially all of his code for the past six months. His job is no longer writing prompts. His job is writing loops. Instead of telling an AI what to do step by step, developers increasingly give a system a goal and let it run an autonomous cycle: • Break the problem into subtasks • Assign work to specialized agents • Review the results • Find mistakes • Send fixes back for another iteration • Repeat until the objective is completed The shift is subtle but important. Prompt engineering is about crafting instructions. Loop engineering is about designing systems. @aipost 🏴
