Shifting from Prompt Engineering to Loop Engineering
mathemagie · x · 2026-07-17
This article discusses a trend: over the past two years, making AI agents better relied mostly on "writing better prompts"; but now, truly effective engineering practices are shifting toward "writing loops."
The core message is:
- The best engineers have long stopped focusing on single-turn prompts, opting instead to build loop structures that repeatedly execute, gather feedback, and self-correct.
- This approach is better suited for complex tasks than a single prompt, as agents need to continuously observe outcomes and adjust their next steps rather than generating a one-shot output.
- The author describes this as a paradigm shift: moving from prompt engineering to loop engineering.
