This library contains a number of components and commands for querying and manipulating Grasshopper components dynamically. You can retrieve components and objects based on their type, their library, the group they're in, or by selecting them directly - or even get all the objects in a document at once. You can then retrieve information about these components + parameters, the libraries they belong to. You can also manipulate objects directly: enabling/disabling, turning preview on and off, changing the color of groups, the text and size of scribbles, and the shape of sketch objects.
