Mini course

Loop Engineering

Design the loop that runs your prompts — not just the prompt itself.

A course on the shift from prompting a language model to designing the loop that runs it. Six chapters covering the mental shift, what triggers the loop, what happens each cycle, how state carries between runs, complete worked examples, and the human role that never goes away. Sits between our Prompt Engineering course (the craft of the prompt) and Claude Code for Developers (one concrete implementation of these ideas). Model-agnostic and mostly tool-agnostic — you can build loops with almost anything; this course teaches the shape.
