## AI overview

The article argues that working effectively with coding agents is shifting from writing individual prompts to designing autonomous loops that generate prompts, use tools, and run longer with less human intervention. It presents loop engineering as a third era after prompt engineering and context or harness engineering, while noting that token costs require caution.
