"The Guidance Automation Extensions (GAX) expands the capabilities of Visual Studio by allowing architects and developers to run guidance packages, such as those included in Software Factories, which automate key development tasks from within the Visual Studio environment.
The Guidance Automation Toolkit (GAT) is an extension to Visual Studio that allows architects to author rich, integrated user experiences for reusable assets including frameworks, components and patterns. The resulting Guidance Packages are composed of templates, wizards and recipes, which help developers build solutions in a way consistent with the architecture guidance."
This will be immensely useful to make sure that the project "stays within the defined architectural limits" and will promote better programming and design in general!
