Next steps:
  1. In VS Code: Ctrl+Shift+P -> "Developer: Reload Window"
  2. In any VS Code terminal, run:

       arabic claude

     Any Claude Code flag passes through, e.g.:
       arabic claude --dangerously-skip-permissions
       arabic claude --resume

  3. The first time, VS Code asks "Allow 'Claude Arabic Terminal' to open this URI?"
     -> tick "Do not ask me again" and click Open.

Claude Code then runs in an Arabic-capable pane inside the VS Code terminal area.
