[Bug] AskUserQuestion tool returns empty answer without user interaction

Bug Description
Regarding the question you noticed: you're right, that looks like a bug. When I used AskUserQuestion to present the Linear ticket options, the system recorded a response even
though you may not have explicitly interacted with it (or the default/first option was auto-selected). This is unexpected behavior — the tool should wait for your actual input.

You can report this at: https://github.com/anthropics/claude-code/issues

Specifically, the issue is: AskUserQuestion tool sometimes returns "User has answered your questions: ." with an empty answer, proceeding without the user actually selecting an
option. This happened during the /linear skill flow when presenting ticket options.
