Page load times above 800ms are unacceptable — AI agents can fix them
Before the agent optimized the app, several pages were loading in the 815–893ms range. As the developer put it, 'This is a sin in web development. Like this cannot happen.' After the agent worked through the code — originally written by GPT-4.5 — load times dropped dramatically: Connectors went from 815ms to 60ms, Email from 817ms to 61ms, Skills from 893ms to 74ms, and Agents inventory from 817ms to 71ms. The key point is that the agent didn't just claim it fixed the problem — it produced measurable proof in the pull request so the human reviewer could verify the improvement without reading a single line of code.
