Devs add 10x more test harnesses just to slow down AI coding agents

- In a thread on AI coding pace, developer cjimti says they deliberately add 10x more test harnesses than any human would tolerate — including mutation testing — just to slow their coding agents down.
- fjzeit replies that this is exactly the behavior they're trying to stem: a feature that once took weeks now takes at most 1-2 hours, and the endorphin rush of building at that speed traps them in a "one more hit" loop until sunrise.
