Claude Code

Continuing from the previous post: after binding a custom domain to EmDash, I nearly locked myself out of the admin panel I'd just set up. Because WebAuthn is strictly bound to the domain, my existing Passkey stopped working, and I hadn't configured any email service yet. This post documents the nail-biting escape: how I used Claude Code to set up Cloudflare Email Sending as a lifeline, tracked down the broken magic links caused by a missing siteUrl, and finally resolved the Passkey binding issue on the custom domain.

I've been blogging on and off for years, trying WordPress, Jekyll, and Ghost before finally settling on Astro. Then Cloudflare announced EmDash, their WordPress competitor, and after watching it for a few months, I decided to make the move. Now, in 2026, I've handed the entire migration over to Claude Code—drop in an official docs link, and the AI analyzes the project, installs the Connector, and even sets up D1 and R2 for me. This post documents the smooth initial deployment, plus two critical gotchas you need to know at the end.

Claude Code's desktop app kept insisting I install Git, even though git ran perfectly in my terminal. The real culprit wasn't Xcode Command Line Tools or a broken PATH — it was a dead Homebrew symlink from 2022 sitting first in my resolution order. Here's the full debugging trail, including all the dead ends.

How I use Claude Projects for architecture decisions and Claude Code for implementation—keeping thinking and coding deliberately separate, with Lexio as a real-world example.
