I watched the video Dries Buytaert created to show his use of Claude-Codes to make some tweaks to his site. The prospects were exciting, so I decided to push it just a little further.
I simply asked Claude to take the home page of an existing site (with a screen cap) and do the following:

1. Move from CSS to SCSS along with the necessary gulp workflow, npm package adjustments, etc.
2. Improve the SEO
3. Improve the Accessibility

This took me on a few hours of Claude iterations. 

It handled the move from CSS to SCSS without a problem. 
When it came the theme, itself, Claude ran into a number of issues. The first attempt was almost devoid of styling. Claude eventually resorted to trying:

1. Several versions of debugging including creating a module to assist it
2. Reverting to css and creating a module to do a priority insert of it
3. Creating specific overrides to mimic the original header and footer, which it had completely borked.

I blew through my original $5 and then $16 more, and finally decided that the header and footer were a bridge too far and will fix them myself. 

So far, I think Claude is very good for suggestions, and for making tweaks that are code reviewed in advance, but beyond that it needs to mature a bit.

Below are the original banner, and the Claude-produced one.
