Loop Engineering
O'Reilly Radar, Monday, June 22nd, 2026
Loop engineering means building systems that prompt AI coding agents on schedules instead of directing them turn-by-turn.
Loop engineering shifts developers from manually prompting AI coding agents to building systems that prompt them automatically on schedules.
Effective loops require five components: automations for scheduled discovery, worktrees for parallel isolation, skills for project knowledge, plugins and connectors for tool integration, and subagents for separate verification.
Persistent memory outside conversations, kept in Markdown files or project boards, is essential because models forget between runs.
Verification remains a human responsibility, since the job is to ship code you confirmed works.
Loops amplify both productivity and risk, accelerating thoughtful engineers while enabling cognitive surrender in others.
