Craftcms Skill for Claude
Craft CMS 5 plugin and module development — extending Craft with PHP. Covers elements, element queries, services, models, records, controllers, migrations, queue jobs, console commands, field types, native fields, events, behaviors, Twig extensions, widgets, filesystems, permissions, project config, GraphQL, testing, and debugging. Triggers on: beforePrepare()/afterSave()/defineSources()/defineTableAttributes()/attributeHtml(), MemoizableArray, BaseNativeField, EVENT_REGISTER_*/DEFINE_*/BEFORE_*/AFTER_*, CraftVariable, custom element or field type (normalizeValue/serializeValue/inputHtml), webhook, API endpoint, queue/batch job, CP section, dashboard widget, utility page, element action/exporter/condition, registerUserPermissions, requirePermission vs requireAdmin, kebab-case permission handles, allowAdminChanges, canView/canSave/canDelete, defineRules, elevated session, project-config/apply, drafts/revisions, element edit sidebar (EVENT_DEFINE_SIDEBAR_HTML) + toolbar buttons, metaFieldsHtml, VueAdminTable, GeneralConfig, getIsMultiSite/refreshSites stale after creating a site, deleteSite phantom sites, element query stops filtering by siteId, naive UTC datetime columns and strtotime drift, element-query ['like'] tuple matches nothing. Always use when writing, editing, or reviewing Craft plugin/module PHP — even when no API is named. For plugin-specific work also load craft-plugins. Do NOT trigger for front-end Twig (craft-site) or content modeling (craft-content-modeling).

Use when implementing any feature or bugfix, before writing implementation code
Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first
Use when creating new skills, editing existing skills, or verifying skills work before deployment - applies TDD to process documentation by testing with subagents before writing, iterating until bulletproof against rationalization
Rules for writing and reviewing tests in the Remotion repository. Use whenever adding, editing, or reviewing tests, especially for Studio UI, rendering, CLI, server, media, and cross-package changes, to prefer complete integration workflows over narrow helper tests and implementation details.
Patterns and pitfalls for the ONNX domain Attention operator (opset 23/24) CUDA implementation. Use when modifying the dispatch cascade in core/providers/cuda/llm/attention.cc, writing mask/bias CUDA kernels, debugging attention test routing, or adding features to the ONNX Attention op. NOT for contrib domain MultiHeadAttention/GroupQueryAttention.
