Loop Engineering Is Here.\n\n## Learn what Loop Engineering is, why it matters, and how AI engineers are building autonomous agent workflows.\n\nA clip went viral in June 2026 and stopped a lot of engineers cold.\n\n[ Boris Cherny](https://thenewstack.io/loop-engineering/) — creator and head of Claude Code at Anthropic — told interviewers that his job had changed:\n\n“I don’t prompt Claude anymore. I have loops running that prompt Claude and figuring out what to do. My job is to write loops.”\n\nThe same week, OpenAI engineer [ Peter Steinberger](https://letsdatascience.com/news/engineers-embrace-loop-engineering-for-ai-agents-cb1a1d6a) posted:\n\n“You shouldn’t be prompting coding agents anymore. You should be designing loops that prompt your agents.”\n\nThen Google engineer [ Addy Osmani](https://cobusgreyling.substack.com/p/loop-engineering) gave the pattern a name:\n\n*loop engineering.*“**Prompt engineering is dead**” started trending.\n\n*This article explains what loop engineering actually is, what changed, and why it matters for the future of building with AI.*\n\nLoop engineering is the practice of designing AI systems that generate, evaluate, and improve their own work until they meet a predefined goal.In one sentence:", "url": "https://wpnews.pro/news/prompt-engineering-is-dead-loop-engineering-is-here", "canonical_source": "https://pub.towardsai.net/prompt-engineering-is-dead-loop-engineering-is-here-32191dd20066?source=rss----98111c9905da---4", "published_at": "2026-07-09 11:30:36+00:00", "updated_at": "2026-07-09 11:47:58.743073+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-agents", "ai-tools", "ai-research", "developer-tools"], "entities": ["Boris Cherny", "Anthropic", "Claude Code", "OpenAI", "Peter Steinberger", "Addy Osmani", "Google"], "alternates": {"html": "https://wpnews.pro/news/prompt-engineering-is-dead-loop-engineering-is-here", "markdown": "https://wpnews.pro/news/prompt-engineering-is-dead-loop-engineering-is-here.md", "text": "https://wpnews.pro/news/prompt-engineering-is-dead-loop-engineering-is-here.txt", "jsonld": "https://wpnews.pro/news/prompt-engineering-is-dead-loop-engineering-is-here.jsonld"}}
