On Loop Engineering | Masahiro Muto

Things are moving fast around AI Coding Agents. We’ve gone from prompt engineering → context engineering → harness engineering, and now there’s also a technique called loop engineering.

This article from Classmethod explains it clearly: dev.classmethod.jp

This other article is also good for getting the general shape of loop engineering: zenn.dev

There’s an Agent SDK as well (I believe Codex has something similar, though I don’t know it well), and it looks like a fair amount of AI Coding Agent functionality can be implemented directly as a program. code.claude.com
