Three weeks ago I asked Claude to build a landing page.

It took about a minute. The output was clean, structured, looked exactly right. I deployed it, sent the link to someone, moved on Yesterday a client asked me to change the CTA button color.

I opened the file.

I had no idea where anything was.

Not because the code was bad. The code was fine. But I had never read it. I watched it appear in a chat window, decided it looked right, and shipped it. The mental model I would normally build while writing code never formed because I never wrote the code.
