About Aylur's GTK Shell
AGS is a command-line scaffolding tool for projects built with Astal and Gnim, which are used to create desktop shells. Astal is described as a set of libraries written in Vala and C that simplify writing a desktop shell. Gnim is a library that adds JSX syntax to GJS, a JavaScript runtime built on Firefox's SpiderMonkey engine and the GNOME platform libraries.
The project is open source and released under the GPL-3.0 license. The repository points to a wiki for getting started. The source does not list supported operating systems or platforms beyond the repository topics, which include Wayland, layer-shell, GTK 3, GTK 4, and TypeScript.
