I Turned My Claude Code History Into an SAO-Style Floating Castle

A few weeks ago, I was trying to find an old Claude Code session where I had built a small automation script. I remembered the idea. I remembered the project. I even remembered the vibe of that late-night debugging session. But finding it? Impossible. Just endless chat history. That’s when I had a stupid but fun idea: What if my chats looked like Sword Art Online’s Aincrad instead of a sidebar? And somehow… that turned into a real thing. So What Is This? I built a custom Claude Code skill that converts my latest 20 sessions into a floating anime-style castle. Every session becomes a floor.
