Grok 4.5 cannot use AskQuestion tool

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Tried many times but the AskQuestion tool seems to fail with Grok 4.5.
It tries and say it’s not in its native tool list and cant find the tool. As soon as I switch to composer 2.5 in the exact same chat it’s able to use it. Official docs says the tool is available for Grok 4.5

Steps to Reproduce

Ask to use the AskQuestion tool in a session

Expected Behavior

Being able to construct and let user pick from multiple choice.

Operating System

MacOS
