I am not sure if this is something we can control on our end, but I find the prompt "widget" in the running tasks confusing, to say the least. Let me explain what I mean, but first: a screen shot:

Problems:

• the button with a tray icon is an "upload file" button, but it took me a while to get it, because there is no tooltip
• it appears that this button is functional even when the agent is running, despite the prompt being inactive
• the button with a square icon is an "interrupt" button, but again: it has no tooltip
• pressing the button interrupts the agent, which can be a pretty big surprise for someone just trying to click it to see what happens
• the button with a paper plane is used to issue new prompts and again it has no tooltip
• all of the above buttons become vaguely dimmed with hover-over action -> why?
• the same widget changes its height if I switch the mode from "text" to "control" (see the screen shot below)

• both the "text" and "control" modes show the upload button, which is a bit weird - upload is in fact the third mode of operation, so how about showing it somewhat like this (see a mockup below but please disregard the dialog format)?
