Twig coding standards and conventions for Craft CMS 5 templates. ALWAYS load this skill when writing, editing, or reviewing any .twig file in a Craft CMS project — even for small edits. Covers: variable naming (camelCase, no abbreviations), null handling (?? operator, ??? with empty-coalesce plugin), whitespace control ({%- trimming, NOT {%- minify -%}), include isolation (always use 'only'), Craft Twig helpers ({% tag %}, tag(), attr(), |attr filter, |parseAttr, |append, svg()), collect() for props and class collections, .implode(), comment headers with ========= separators on component files, and common pitfalls (snake_case, macros as components, hardcoded colors). Triggers on: Twig template creation, editing, or review; .twig files; {% include %} with 'only'; {% tag %} and polymorphic elements; collect() and props.get(); class string building; attr() and |attr filter; svg() with styling and aria; ?? and ??? null coalescing; whitespace control and blank lines in output; minify alternatives; Twig file headers and comment blocks; variable naming conventions in Twig; currentSite, siteUrl, craft.entries, .eagerly(), .collect in template context; |e('js') aggressive escaping (spaces become \uXXXX), js escaper, grepping escaped translated strings. NOT for Twig architecture patterns, atomic design structure, or template routing (use craft-site). NOT for PHP code (use craft-php-guidelines). NOT for content modeling or field configuration (use craft-content-modeling).
