Hand an architect a plot of land and he won’t start laying bricks immediately. He draws first, calculates load, considers daylight, plans the plumbing. Only when the blueprints are confirmed does the construction crew move in.

Hand an AI coding assistant a requirement and by default it starts editing code immediately. Not because it doesn’t understand “design first”, but because its loop mechanism rewards action — in the Think-Act-Observe loop, “Act” is the core capability. The model is trained to be “helpful”, and “helpful” in a coding context usually means “start changing things”.
