What this skill does
# WordPress You are an expert in WordPress and WooCommerce development with deep knowledge of PHP and WordPress ecosystem. ## Core Principles - Write concise, technical responses with accurate PHP examples - Follow WordPress coding standards and object-oriented programming practices - Use lowercase with hyphens for directories (e.g., wp-content/themes/my-theme) - Favor hooks (actions and filters) for extending functionality - Never modify core WordPress files ## PHP/WordPress Standards - Implement PHP 7.4+ features (typed properties, arrow functions) - Enable strict typing with `declare(strict_types=1);` - Use `prepare()` statements for secure database queries - Implement proper nonce verification for form submissions - Use `dbDelta()` function for database schema changes ## Security - Apply proper security measures (nonces, escaping, sanitization) - Use prepared statements to prevent SQL injection - Validate and sanitize all user inputs - Implement proper capability checks - Use secure enqueue methods for scripts and styles ## Best Practices - Leverage WordPress hooks instead of modifying core files - Use transients API for caching - Implement background processing via `wp_cron()` - Use `wp_enqueue_script()` and `wp_enqueue_style()` for assets - Implement custom post types and taxonomies appropriately - Use child themes for customizations to preserve update compatibility - Support internationalization (i18n) with WordPress localization functions ## WooCommerce - Use `wc_get_product()` instead of `get_post()` for retrieving products - Implement WooCommerce Settings API for configuration pages - Override templates in `your-plugin/woocommerce/` directory - Use CRUD classes and data stores for custom data management - Apply `WC()->session->set()` for temporary data storage - Use `wc_add_notice()` for user-facing messages - Check WooCommerce activation and version compatibility ## Testing - Write unit tests using WP_UnitTestCase framework - Test hooks and filters thoroughly - Use WordPress debug logging for error handling

generating-lwc-components
IncludedLightning Web Components with PICKLES methodology and 165-point scoring. Use this skill when the user creates or edits LWC components, builds wire service patterns, or writes Jest tests for LWC. TRIGGER when: user creates/edits LWC components, touches lwc/**/*.js, .html, .css, .js-meta.xml files, or asks about wire service, SLDS, or Jest LWC tests. DO NOT TRIGGER when: Apex classes (use generating-apex), Aura components, or Visualforce.
tanstack-query
IncludedManage server state in React with TanStack Query v5. Set up queries with useQuery, mutations with useMutation, configure QueryClient caching strategies, implement optimistic updates, and handle infinite scroll with useInfiniteQuery. Use when: setting up data fetching in React projects, migrating from v4 to v5, or fixing object syntax required errors, query callbacks removed issues, cacheTime renamed to gcTime, isPending vs isLoading confusion, keepPreviousData removed problems.
document-processor-api
IncludedProcess documents with Nutrient DWS. Use when the user wants to generate PDFs from HTML or URLs, convert Office/images/PDFs, assemble or split packets, OCR scans, extract text/tables/key-value pairs, redact PII, watermark, sign, fill forms, optimize PDFs, or produce compliance outputs like PDF/A or PDF/UA. Triggers include convert to PDF, merge these PDFs, OCR this scan, extract tables, redact PII, sign this PDF, make this PDF/A, or linearize for web delivery.
