While working on a series of Tracking categories on a few wikis in different languages - I noticed how glaring the inconsistencies in the grammatical framing and structure of the entries across the Special:TrackingCategories page on Wikimedia wikis.

Suggest making some updates to provide for greater consistency, increase use of links to related MediaWiki.org documentation where possible, and reduce possible confusion across languages.

• broken-file-category-desc: The page contains a broken file link (a link to embed a file when the file does not exist).
• duplicate-args-category-desc: The page contains template calls that use duplicates of arguments, such as <code><nowiki>{{foo|bar=1|bar=2}}</nowiki></code> or <code><nowiki>{{foo|bar|1=baz}}</nowiki></code>.
• expansion-depth-exceeded-category-desc: The page exceeds the maximum expansion depth.
• expensive-parserfunction-category-desc: The page uses too many expensive parser functions (like <code>#ifexist</code>). See [https://www.mediawiki.org/wiki/Special:MyLanguage/Manual:$wgExpensiveParserFunctionLimit Manual:$wgExpensiveParserFunctionLimit].
• hidden-category-category-desc: The category contains <code><nowiki>__HIDDENCAT__</nowiki></code> in its page content, which prevents it from showing up in the category links box on pages by default.
• index-category-desc: The page has a <code><nowiki>__INDEX__</nowiki></code> on it (and is in a namespace where that flag is allowed), and hence is indexed by robots where it normally wouldn't be.
• node-count-exceeded-category-desc: The page exceeds the maximum node count.
• noindex-category-desc: The page is not indexed by robots because it has the magic word <code><nowiki>__NOINDEX__</nowiki></code> on it and is in a namespace where that flag is allowed.
• nonnumeric-formatnum-desc: The page contains a non-numeric argument to the formatnum parser function.
• post-expand-template-argument-category-desc: The page is bigger than <code>$wgMaxArticleSize</code> after expanding a template argument (something in triple braces, like <code>{{{Foo}}}</code>).
• post-expand-template-inclusion-category-desc: The page size is bigger than <code>$wgMaxArticleSize</code> after expanding all the templates, so some templates were not expanded.
• restricted-displaytitle-ignored-desc: The page has an ignored <code><nowiki>{{DISPLAYTITLE}}</nowiki></code> because it is not equivalent to the page's actual title.
• template-equals-category-desc: The page contains <code><nowiki>{{=}}</nowiki></code> but on this wiki that does not expand to <code>=</code>. This usage is deprecated; a future MediaWiki version will implement <code><nowiki>{{=}}</nowiki></code> as a parser function.
