Why do you want you coding agents to be in a terminal? A terminal is missing latex rendering, inline images, a browser showing what the agent is clicking on, being able to view a spreadsheet and then select a region to reference in the conversation, clickable links when it references a specific line number with mouse-over previews, and interactive inline visualisations. A coding agent missing any of those is a significantly worse experience, yet people are for some reason willing to give up all of them to have their coding agents run in a terminal. It's not even like you get a familiar environment to work in, nothing that you set up in your terminal carries over into your agent or IDE.
