Craft CMS 5 PHP coding standards and conventions. ALWAYS load this skill when writing, editing, reviewing, or discussing any PHP file in a Craft CMS plugin or module — even for small edits. Also load when running ECS, PHPStan, or scaffolding with ddev craft make. Covers: PHPDoc blocks (@author, @since, @throws chains, documenting exceptions), section headers (=========), class organization, naming conventions (services, queue jobs, records, events, enums), defineRules() and validation, beforePrepare() and addSelect(), MemoizableArray, DateTimeHelper vs Carbon, stricttypes and declare(stricttypes=1) usage, short nullable notation (?string), typed properties, void return types, control flow patterns (early returns, match over switch), CP Twig template conventions, form macros, translations (Craft::t), ECS/PHPStan configuration, scaffolding commands, and the verification checklist. Triggers on: writing service classes, models, controllers, elements, element queries, records, queue jobs, migrations, or any PHP class in a Craft CMS context. Also triggers on PHP code review, refactoring, or style questions for Craft plugins and modules. NOT for front-end Twig templates (use craft-twig-guidelines), template architecture (use craft-site), or CP JavaScript/Garnish (use craft-garnish). If you are touching PHP code in a Craft CMS context, you need this skill.
