Bug: /memory UI shows garbled ANSI escape characters when selecting option

Description

When using the /memory command and selecting any option (1, 2, or 3), garbled ANSI escape characters (^[[0) appear at the bottom of the screen. After this, the UI becomes unresponsive and cannot be navigated back.

Steps to Reproduce

1. Run /memory in Claude Code
2. Select any option (1. User memory, 2. Project memory, or 3. Open auto-memory folder)
3. Press Enter to confirm

Expected Behavior

The selected memory option should open normally without rendering issues.

Actual Behavior

Garbled characters (^[[0) appear below the menu regardless of which option is selected, and the UI becomes stuck — cannot go back or interact further.

Screenshot

The escape sequence ^[[0 is visible at the bottom after selecting any option:

Enter to confirm · Esc to cancel
^[[0

Environment

• Claude Code version: 2.1.63
• macOS version: 26.2
• Terminals tested: Ghostty, iTerm2 (both reproduce the issue)
• Shell: zsh

Note

• This is not terminal-specific — the bug reproduces across multiple terminal emulators (Ghostty, iTerm2).
• All three menu options trigger the same issue, not just option 1.
