HarnessTax
A concept in AI coding agent development referring to the degree to which an engineering harness or framework influences a model's actual performance. This encompasses both benefits, such as improved task completion rates, and costs, including additional token consumption, latency, and constraints on model capabilities.

HarnessTax is a metaphor suggesting that the harness layer can bring both benefits (improved reliability and task completion rate) and costs or losses (additional token consumption, latency, and restrictions on model capability).
HarnessTax is currently more of a framework-level question than a conclusion with sufficient empirical support.
