Loop Engineering from First Principles — Kyle Mistele, HumanLayer

About

A coding agent will happily hand you a 40,000 line pull request that nobody can review and that quietly does the wrong thing. Kyle Mistele's argument is that the fix is not a better prompt but a better loop, borrowed from control theory: a thermostat senses the error between where a system is and where you want it, emits a control signal, and measures again, over and over. Infrastructure as code already approximates this. The point is to design agent loops the same way, so each iteration makes a
