Object-Oriented Harness: Evolving Agent Harnesses through Object-Oriented Design
The real insight here is that monolithic harnesses are the wrong architecture for multi-task agents. OO-Harness treats harness design like software engineering, creating inheritance hierarchies that let you tune execution strategy per task class without retraining the model. If you're building agents that handle heterogeneous workflows, this is a concrete pattern to steal: separate your task router from your execution controller and let each specialization evolve independently.
