Background: Sometime in early 2026 I started using Cloud Code Session from the IDE only in the terminal (in my case, the standard macOS terminal). Sometimes I run 4+ sessions simultaneously. For so many projects, a thin terminal window seemed more lightweight to me than 4 full-fledged IDEs. This created a new problem. With the regular terminal I was constantly CMD-tabbing into the wrong window and giving the wrong instructions to the wrong agent, because virtually every terminal window and every project looked exactly the same. Additionally, I couldn’t tell when an agent was done and I was regularly missing those confirmation requests in some ofgs. It was exciting to do a lot of work with Cloud Code, but at one point I became seriously stressed by this workflow. The context change in particular was truly soul-stirring. So, I created this new tool Mantle, which is basically a wrapper for the regular macOS Terminal: it looks like the normal Terminal, but now each folder/project gets its own color, icon, and name in the title bar – assigned automatically by the folder name. I can also customize each project with a simple CLI command, which can then be committed to version control (ie no matter what your project/folder looks like, it stays inside the project). In the Dock, each Terminal instance now shows its own project icon, so when I have five sessions running I can quickly find the right one instead of fishing through identical Terminal icons. It also creates one Dock icon per session (I know, this is somewhat contrary to the way Mac apps are organized, but still, I liked the extra clarity). One thing that helped me a lot especially with Cloud Code: When an agent stops to ask for permission and you’re in another window, the app pings you clearly. Now the prompt will no longer disappear for ten minutes. It uses your default shell, so Cloud Code runs exactly as before. I made it for myself but then decided to release it. This workflow improvement definitely reduced the pain for me.
