TIL: You can set IS_DEMO=1 to simplify the welcome screen of Claude Code. There are two types of welcome screens (shown below), and there’s no obvious logic behind which one appears for a given project — I found this annoying. After digging into it, I discovered an undocumented environment variable IS_DEMO¹ that forces the simpler one. Run IS_DEMO=1 claude, or set it in Claude Code’s settings.json under the env key.
