Diagnostics

The diagnostics script needs to be defined in the mycroft.conf file, under the DiagnosticsSkill section. You can find more information about configuration files in the official Mycroft Documentation. The script can be the output to any program you'd like. Whatever the stdout is, will be what mycroft says. Remember to restart the mycroft skills service once you add this.
