summary: "Eyad Khrais explains that harness engineering is crucial for AI agents, comparing the AI model to a brain and the harness to the body that must be custom-built. While models can be accessed via APIs, the engineering work to create the operational framework around them is the most important aspect of AI development."

# Eyad's Status Update on X

Eyad @eyad_khrais Article AI Harness Engineering 101 If an AI model is the brain of an agent, the harness is the body. You can call a model via APIs, but the body has to be built by yourself – which is why harness engineering is the most important... 10:43 PM · Jun 23, 2026 770 Views :host{display:inline-block;direction:ltr;white-space:nowrap;line-height:1}span{display:inline-block}:host([data-will-change]) span{will-change:transform}.number,.digit{padding:round(nearest, calc(var(--number-flow-mask-height, 0.25em) / 2), 1px) 0}.symbol{white-space:pre} 1 :where(number-flow-react){line-height:1}number-flow-react > span{font-kerning:none;display:inline-block;padding:calc(round(nearest, calc(var(--number-flow-mask-height, 0.25em) / 2), 1px) * 2) 0} 1 :host{display:inline-block;direction:ltr;white-space:nowrap;line-height:1}span{display:inline-block}:host([data-will-change]) span{will-change:transform}.number,.digit{padding:round(nearest, calc(var(--number-flow-mask-height, 0.25em) / 2), 1px) 0}.symbol{white-space:pre} 1 2 :where(number-flow-react){line-height:1}number-flow-react > span{font-kerning:none;display:inline-block;padding:calc(round(nearest, calc(var(--number-flow-mask-height, 0.25em) / 2), 1px) * 2) 0} 12 :host{display:inline-block;direction:ltr;white-space:nowrap;line-height:1}span{display:inline-block}:host([data-will-change]) span{will-change:transform}.number,.digit{padding:round(nearest, calc(var(--number-flow-mask-height, 0.25em) / 2), 1px) 0}.symbol{white-space:pre} 8 :where(number-flow-react){line-height:1}number-flow-react > span{font-kerning:none;display:inline-block;padding:calc(round(nearest, calc(var(--number-flow-mask-height, 0.25em) / 2), 1px) * 2) 0} 8 Read 1 reply
