(Picture this)It s 4:30 PM on a Friday. You ve just cracked the logic for that complex auth-flow refactor. You ve been in the zone for six hours straight headphones on, coffee empty, absolute flow state.
Here s something uncomfortable I ve learned building AI agent systems:
AI rarely fails at the step we re watching.
It fails somewhere quieter a retry that hides a timeout, a queue that grows by every hour, a memory leak that only matters at scale, a slow drift that looks like variation until it s too late.
Most teams measure accuracy. Some measure latency.
