The job of building AI agents is evolving beyond simple prompt engineering. It now encompasses three distinct disciplines: prompt engineering for shaping model behavior, context engineering for managing the information within the model's limited window, and harness engineering for building the surrounding software infrastructure. Confusing these roles can lead to costly mistakes, such as focusing on wording while ignoring data accuracy or safety protocols. AI
