AskUserQuestion tool returns without capturing user answers

Description

The AskUserQuestion tool consistently returns "User has answered your questions: . You can now continue with the user's answers in mind." without including the actual user selections. This makes the tool unusable for interactive workflows.

Steps to Reproduce

1. Use AskUserQuestion with single-select or multi-select questions
2. User selects an option
3. Tool returns the generic message above with no answer data

Expected Behavior

The tool result should include the user's selected option(s) so the assistant can act on them.

Actual Behavior

Tool returns a generic acknowledgment with empty answer content regardless of what the user selects.

Environment

• Claude Code CLI
• macOS (Darwin 25.3.0)
• Model: claude-opus-4-6

Additional Context

Observed across multiple consecutive AskUserQuestion calls in the same session. Both single-select and multi-select questions are affected.
