What's Wrong?

I was using Claude Code with the Chrome plugin for UAT on an app I'm building. It crashed after a couple of hours, but I'm unsure what happened. This was on MacOS, using latest version of Claude Code (2.1.63), with the Chrome beta plugin. I was running iTerm2 inside of tmux.

This is the codebase I was running UAT against. It's a javascript browser game. I doubt that it's relevant.

What Should Happen?

Claude should not crash :)
