Content modeling methodology for Craft CMS projects. Use when designing content architecture, planning sections and fields, configuring Matrix fields, setting up CKEditor, advising on content model decisions, or structuring any CMS project. Trigger this skill when the user asks about sections vs channels vs structures, Matrix nesting strategy, entry type sharing, when to use CKEditor vs Matrix, field naming conventions, how to model relationships, color strategy for entry types, or any "how should I structure this content" question. Also trigger when planning new Craft projects from scratch, reviewing existing content models for improvements, onboarding a client to Craft CMS content architecture, or designing the content model for an Assembly pilot's public-facing site. Covers the three-layer approach (Foundation, Structure, Experience), design system conventions, and all Craft 5.5-5.9 field types and features.

Patterns and breaking changes for Craft CMS 4 to 5 migrations. Use when upgrading Craft versions, fixing Craft 5 compatibility issues, updating code for Craft 5 patterns, or debugging migration problems. Trigger this skill when the user mentions upgrading Craft, when queries return empty results unexpectedly (the empty array breaking change), when GraphQL types aren't found (section prefix removal), when Matrix blocks aren't rendering (block.type -> block.type.handle), or when planning an entrification strategy for categories/tags/globals. Also trigger when checking plugin compatibility for Craft 5 or asking about new features in 5.5-5.9. Covers Matrix changes, empty array behavior, GraphQL updates, entrification, conditional field layouts, and all features through 5.9.

Codex skill alias for /craft-debug. Debug Craft CMS issues with systematic analysis

Craft CMS development expertise for building sites, debugging issues, and providing community support. Use when working with Craft CMS templates (Twig), element queries, GraphQL API, Matrix fields, relational fields, eager loading, caching, plugins, or answering Craft CMS technical questions. Trigger this skill for ANY Craft CMS question -- entry queries, Matrix nesting, relatedTo directions, GraphQL mutations, template debugging, CP issues, .all() vs .one(), conditional field layouts, or "why does my query return nothing." Also trigger when helping in Craft Discord or Stack Exchange, when the user pastes Twig code with craft.entries(), or when debugging N+1 queries or cache invalidation. Covers Craft 4 and Craft 5 patterns including all breaking changes between versions and features through 5.9.

Craft CMS MCP server tools for direct database and schema access. Use when querying Craft entries, inspecting field layouts, checking section configurations, listing assets, debugging content relationships, validating content model structure, creating or updating entries, browsing asset volumes, or diagnosing plugin issues through the MCP server. Trigger this skill when the user has the craft-mcp plugin installed and wants to inspect their Craft installation programmatically -- listing sections, checking entry types, running database queries, viewing deprecation warnings, debugging errors via logs, auditing content architecture, or testing GraphQL queries. Also trigger when verifying that template code matches the actual content model, when the user says "check my Craft setup" or "what sections do I have," or during any migration planning that needs schema inspection.
