C:/Program Files/Git/focus command not recognized (Unknown command) on Windows v2.1.116

[saitoko]

Describe the bug

The /focus slash command returns "Unknown command" in the Claude Code CLI on Windows, even though it was reportedly added in v2.1.110.

To Reproduce

1. Open Claude Code CLI in a terminal on Windows
2. Type /focus and press Enter
3. "Unknown command: /focus" is returned

Expected behavior

/focus should toggle the focus view as described in the changelog for v2.1.110.

Environment

• OS: Windows 11
• Claude Code version: 2.1.116
• Installation method: Windows installer (not via npm)

Additional context

• Ctrl+O still works for focus view toggling
• /doctor reports no issues
• @anthropic-ai/claude-code does not appear in npm list -g (installed via Windows installer, not npm)
