The Grok tool is a fully extensible, Java-based implementation expertise mining framework. The framework supports heuristic metrics that quantitatively mines artifacts-centric expertise levels from version control and issue tracker repositories.

An integrated communication infrastructure links developers seeking help on given software artifact to the appropriate experts. The skilled experts subset is deduced by a user-defined metric evaluated at runtime. The communications facilities includes sending emails, sharing code pointers using IDEtalk, submitting bug reports or new feature requests.

By default, the expertise query/help action is mapped to Ctrl+Shift+F1.
