A senior WordPress engineer built into Claude — 4 implementation workflows, 5 deep-dive reference modules, 20+ production-ready code patterns. Theme development, plugin building, WooCommerce hooks, Gutenberg blocks, and security best practices, all covered with real depth and copy-paste-ready code.
The problem with asking Claude for WordPress help
Out of the box, Claude gives you surface-level WordPress answers that ignore your theme approach, page builder, PHP version, and existing codebase. You get generic snippets, outdated patterns, and advice that sounds right — until it breaks your site in production.
The fix
WordPress Expert gives Claude deep knowledge of theme architecture (classic and block/FSE), plugin development, WooCommerce customization, Gutenberg blocks, and security best practices — so every answer it gives you is specific, production-ready, and safe to ship.

What you get
How it works
Describe your project and the skill runs a structured discovery process — project type, technical context, client needs, and scale requirements. Then it recommends the exact stack: classic vs block theme, page builder vs custom, hosting setup, and plugin decisions. You get a clear implementation plan before committing to an approach.
You: "I'm building a WooCommerce site for a client. They'll manage content themselves. Should I use Elementor or a custom theme?" Claude: Based on your setup — non-technical client, ecommerce focus, and content management needs — here's the recommendation: → Use Elementor Pro with a lightweight classic base theme (Kadence or GeneratePress) → Reason: Best WooCommerce widget ecosystem + client can manage pages without touching code → Avoid: Custom theme (maintenance burden for non-dev client) → Alternative: Bricks if performance is critical and client is comfortable with a learning curve Ready to start building? I'll walk you through the setup...
When your goal is clear, the skill goes straight to complete, copy-paste-ready code — no pseudocode, no “you’ll need to adapt this.” Every output follows WordPress coding standards, includes inline comments explaining the WHY, and has the security triad applied (nonce, capability check, sanitize/escape).
You: "Write a custom post type for client testimonials with a star rating field" Claude: [Delivers complete plugin file with:] ✓ register_post_type() with all labels and REST API support ✓ add_meta_box() for the star rating field (1–5) ✓ save_post hook with nonce verification + sanitize_text_field() ✓ Template function get_testimonial_rating() for theme use ✓ Where to place the file + activation instructions
Paste any existing WordPress code and the skill audits it for security vulnerabilities (missing nonces, direct DB queries, unescaped output), performance issues (unbounded WP_Query, missing wp_reset_postdata), and WordPress anti-patterns (hardcoded URLs, scripts in header.php, functionality in theme files). You get a prioritized fix list with corrected code.
Have a static HTML/CSS design? The skill walks through the full 10-step conversion: template parts, the Loop, asset enqueuing, nav menus, widget areas, and the critical wp_head() / wp_footer() hooks nothing should ever miss
Bundled reference guides for theme development, HTML-to-theme conversion, plugin development, performance & security, and WooCommerce — loaded on demand for deeper context on any topic
