Hey, thanks for following up. I see you already reported this in [REGRESSION] Hook response fields user_message / agent_message still ignored in Windows v2.0.77.
Like you mentioned there on Dec 20, the first part of the bug (hooks not being called at all) was fixed. The current issue is that agent_message and user_message from hooks aren’t being passed into the model context.
The team is working on this, it’s a known issue.
