[Bug] AskUserQuestion tool auto-answers without showing interactive UI in v2.1.63

Bug Description
The Problem

The AskUserQuestion tool was called 6+ times during the /app-sdlc:plan phase, but the questions were auto-answered with
empty selections — you never got to see or interact with them. The debug log shows:

⏺ User answered Claude's questions:
⎿

...with no actual selections. The model then interpreted the empty response as "user chose the first option" and continued.

Root Cause

This is not a settings issue — your permission settings (defaultMode: "default") are correct and don't auto-approve
AskUserQuestion.

This appears to be a Claude Code UI bug in v2.1.63 where the AskUserQuestion interactive component renders and immediately
resolves without waiting for user input. The questions flash and auto-complete.

Evidence

• No [ERROR] or [WARN] related to AskUserQuestion in the debug log
• The tool executes, hooks fire (0 matched, which is expected), and then the next API call happens almost instantly (~0ms

gap)

• Your settings are clean — no auto-approve rules that would affect this

What to Do

1. Report the bug: https://github.com/anthropics/claude-code/issues — "AskUserQuestion auto-answers without showing

interactive UI, v2.1.63"

1. Workaround for now: The design decisions I made during the /plan phase need your review. The choices were:

• 3 icons (clock, blocked, plus) — no more menu
• Keep chevrons for date navigation
• Navigation bar toolbar (not custom HStack)
• Popovers on iPad, sheets on iPhone
• ViewBuilder injection for popover anchoring
• NavigationSplitView (sidebar hidden by default)
• Simple section list in sidebar
• Calendar-only toolbar (per-section)
• Account section with profile info for Sign Out

Environment Info

• Platform: darwin
• Terminal: ghostty
• Version: 2.1.63
