[BUG] /desktop command not recognized in CLI on Windows ARM64

Description

The /desktop command is not available in Claude Code CLI on Windows ARM64. Typing /desktop in an active CLI session returns:

Unknown skill: desktop

Expected behavior

Per the documentation, /desktop should save the current CLI session and open it in the Claude Desktop app, then exit the CLI. The docs state this is available on macOS and Windows.

Environment

• Claude Code version: 2.1.101 (latest, confirmed via claude update)
• OS: Windows ARM64
• Claude Desktop app: Installed and running

Steps to reproduce

1. Open a terminal on Windows ARM64
2. Run claude to start a CLI session
3. Type /desktop
4. Observe error: "Unknown skill: desktop"

Additional context

The command does not appear in the / command list at all, suggesting it is not registered on this platform rather than failing at execution time.
