In the field of artificial intelligence, a new paradigm called "Loop Engineering" is rapidly replacing traditional Prompt Engineering. According to Business Insider, Boris Cherny, the creator of Claude Code, recently admitted: "I no longer write prompts manually." He explained that Loop Engineering enables AI agents to autonomously call models, iterate tasks, and even optimize outputs through self-feedback. Peter Steinberger, an OpenAI engineer and creator of the viral project OpenClaw, also publicly reminded users on social media: "This is your monthly reminder—you should not be manually writing prompts for coding agents anymore."
The core of Loop Engineering lies in allowing AI agents to autonomously complete multi-step tasks through loop structures without requiring human input for each step. For example, an agent can automatically send prompts to Claude, receive responses, evaluate results, and generate new prompts based on the outcome, forming a continuous self-optimizing loop. Claire Vo, founder of ChatPRD, summarized it this way: "It's essentially a reminder that you don't have to type prompts manually to get an agent working for you." Cherny even considers loops and similar features to be the work he is most proud of over the next decade.
