Gadgets is a collection of tools to manage Linspector. Rush for example is a Remote User Shell for Linspector.
Rush connects to a Linspector instance using JSON-RPC and provides a similiar interface like the builtin in Lish.
This is currently just for testing and debugging some stuff. Be sure, that the JSON-RPC interface of Linspector does not provide authentication nor encrytion like SSL!
