ANTHROPIC LEAD ENGINEER MAKING $2.3M/YEAR JUST LEAKED A 12-PAGE DOCUMENT - AND GOT FIRED 15 MINUTES AFTER PUBLISHING

most developers build loops - but almost every loop breaks in one of five ways, and each failure has a symptom visible from the outside without reading a single line of code

Blind loop - the agent waits for a human to hand it work every morning - automating execution but not discovery Tangled loop - parallel agents share one directory and overwrite each other parallelism that destroys instead of multiplies Nodding loop - the agent grades its own work and approves it every time a loop that has never said no to itself is broken Amnesiac loop - results live only in the context window every morning the system wakes up with no memory of yesterday Manual loop - no trigger a human presses the button to start it that is not a loop that is a script waiting for a person

a real loop finds its own work - remembers what it did has something that can say no never lets two agents touch the same file and fires itself on a timer

remove any one of the five - and the loop either breaks or never starts
