What's Wrong?

I use VS Code: Sidebar for Claude Code
Most of the time Fabe 5 doesn't show text messages [explaining what it is doing or what it is going to do] in chat. I see only a list of Grep/Read/Thought for Xs/etc]. I find it major issue especially before AskUserQuestion event. It just throws questions to answer without explanation. I need to ask for temporary .md file to produce it.
Opus 4.8 doesn't have this issue.

What Should Happen?

It should include actual chat messages what it has done, what it is doing or what it is going to do, just like Opus.
