## AI overview

The article introduces loop engineering: designing systems that repeatedly prompt, check, record, and direct coding agents instead of manually prompting them turn by turn. It describes the approach as early and potentially costly in token usage, and compares its building blocks with features in Codex and Claude Code.

## Source excerpt

Loop engineering is replacing yourself as the person who prompts the agent.
