The combine.sh script which builds the combined/minified JS files is flawed. As a result, the UsabilityInitiative does not work at all currently if you set $wgUsabilityInitiativeResourceMode to 'combined' or leave it at the default 'minified'.

It is probably assumed the combined JS file will be made from the modules in the following order:

jquery.async.js
...
jquery.textSelection.js

jquery.wikiEditor.js
jquery.wikiEditor.dialogs.js

jquery.wikiEditor.toc.js
jquery.wikiEditor.toolbar.js

However, it is obviously not, because in the alphabetical order (used by “cat js/plugins/*.js”), “jquery.wikiEditor.js” comes only _after_ “jquery.wikiEditor.dialogs.js”. That means the resulting files tries to use $.wikiEditor in jquery.wikiEditor.dialogs.js before it is initialized in jquery.wikiEditor.js

If you do not want to list the files manually, you either need to sort them without the .js extension, or rename them, so that wikiEditor.js comes ahead of everything else.
