phpcs does NOT display the relevant name of the sniff when a sniff fails.
By adding the
-s argument, the sniff names will be displayed. See the following from
-s Show sniff codes in all reports
You can add this to your PHP CodeSniffer XML Ruleset with the following:
<!-- Append arg -s to phpcs to display the name of failed sniffs --> <arg value="s"/>
Editor Specific Configurations

which will display a list of messages that have been displayed (including the full version of the sniff name).
