Craft CMS 5 content modeling — sections, entry types, fields, Matrix, relations, project config, and content architecture strategy. Covers everything editors and developers need to structure content in Craft: choosing section types, designing entry types and field layouts, selecting field types for specific needs, configuring Matrix and nested entries, setting up relations and eager loading, and planning multi-site propagation.

Always use when planning content architecture, creating sections/fields, configuring Matrix, setting up relations, choosing field types, designing field layouts, making content modeling decisions, or planning multi-site content propagation. Do NOT trigger for PHP plugin/module development, custom field type code, front-end Twig templates, or buildchain configuration.

Always use when writing, editing, or reviewing JavaScript that runs in the Craft CP — plugin CP assets, custom field type JS, element index JS, CP webpack config, or code that imports garnishjs or references window.Garnish. Also trigger for CP accessibility, keyboard interactions, drag-sort behavior, or CP JS memory issues. Do NOT trigger for front-end JavaScript (Alpine, Vue, htmx) or Twig templates (craft-site).

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, strict_types and declare(strict_types=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.

Scaffold Claude Code configuration specifically for Craft CMS projects. Generates CLAUDE.md and .claude/rules/ files tailored to the project type (plugin, site, module, hybrid, or monorepo). Only for Craft CMS projects — not for Next.js, Laravel, or other frameworks. Triggers on: 'set up Claude for this Craft project', 'initialize CLAUDE.md', 'scaffold project config', 'configure Claude Code for Craft', 'create CLAUDE.md', 'missing CLAUDE.md', 'does this project have a CLAUDE.md', 'bootstrap Claude config', 'new Craft project setup', 'onboard a developer to this Craft project', 'generate .claude/rules', 'set up coding standards config', 'upgrade Claude config', 'update CLAUDE.md', 'compare my setup', 'is my config up to date', 'audit my Claude setup', 'redo project setup'. Also triggers when starting work in a new Craft CMS project that lacks a CLAUDE.md file, or when the user wants to check or upgrade an existing configuration. Detects project type from composer.json (craft-plugin, craft-module, project), .ddev/config.yaml, templates/, config/project/, and modules/. NOT for installing Craft CMS itself, creating DDEV environments, writing PHP code, building templates, or content modeling. NOT for non-Craft projects — if the project is React, Next.js, Laravel, or any non-Craft framework, this skill does not apply.

Craft CMS 5 front-end Twig development — atomic design, template architecture, components, Vite buildchain. Covers atoms/molecules/organisms, props/extends/block patterns, layout chains, view routing, content builders, image presets, Tailwind named-key collections, multi-brand CSS tokens, JavaScript boundaries (Alpine/DataStar/Vue, tabs, accordions), Vite asset loading, and front-end auth (login, registration, password reset, profiles).

Do NOT trigger for PHP plugin/module development (craftcms) or content modeling (craft-content-modeling).

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).
