Loop Engineering, beyond prompt, context, and harness engineering

"I don't prompt Claude anymore. I have loops running that prompt Claude... My job is to write loops." said Boris Cherny, the creator of Claude Code, demonstrating a change in the way developers work with their favorite coding agent. Developers are moving away from manually coding and writing isolated prompts, and toward Loop Engineering: the practice of designing automated systems that steer coding agents autonomously.

In this 3-hour deep dive, we’ll look at the concepts, approaches, and architecture behind "Loop Engineering". You will learn that the power of AI doesn't (only) lie in the model itself, but in the harness and loops built around it. We will explore the core primitives required to build robust loops (skills, triggers, hooks, Git worktrees, sub-agents, state & memory...), how to implement the fundamental loop structures (turn-based, goal-based, time-based, and proactive), and how to hopefully prevent these autonomous systems from launching rm -Rf on your codebase!

You will leave this session with concrete examples, advice, and tips'n tricks, to build your own loops, replacing tedious manual tasks with self-driving workflows that investigate, implement, and verify their own code and artifacts.
