Yesterday, Anthropic released the latest version of their LLM, Claude 3.7 Sonnet. Alongside the announcement was the release of a new tool: Claude Code, an agentic coding tool available in your CLI (I’ll have more to write on this later).

I wanted to test out both Claude 3.7 and the new CLI tool, so I used it to refactor the theme for the ‘ol bloggy blog. I had been playing around with some updated styles in the past (I considered moving things to a tool that generates static pages — but so. much. work.)

I used Claude Code to basically create a new WordPress theme from scratch, based on the CSS and HTML templates I had already written for my static site. The result is this updated interface! A few neat things I’m able to do:

• Respect user preference for system theme (light vs dark mode)
• Automatically add target=”_blank” to any external link
• Automatically add loading=”lazy” to any img tag.
• And just otherwise clean things up!

Overall, I’m pretty happy with it. Using Claude Code and my API key, it cost $5.83 over 2 hours.

So long, old theme! I hardly knew you. (Hah, that’s not true — I’ve been rocking that thing since 2017.) Posted below for posterity.
