Letting the Agent Touch the Browser Changed My Task List

One developer transitioned their agent from the terminal to the browser to automate reports lacking export buttons. The primary challenge was not clicking, but accurately detecting when pages were ready, as standard sleeps proved unreliable. Separately, a performance analysis revealed that browsers often prioritize fonts and scripts over hero images, delaying Largest Contentful Paint. Implementing the fetchpriority HTML attribute resolves this by overriding the browser's default prioritization, ensuring critical visual elements load first.
