Small requirement — I didn&rsquo;t even write it up, just typed &ldquo;add an export button to the list page&rdquo; into the chat box.</p> <p>The AI delivered in ten minutes. Frontend changes, new endpoint, SQL — all in one pass. I was pleased when I opened the PR, right up until review revealed: the export columns didn&rsquo;t match the list page, a hundred thousand rows would hang the service outright, there was no permission check, and the tests only covered the happy path.</p>
