    About This Skill

    Professional WordPress Block Development at Your Fingertips

    Transform your block ideas into production-ready WordPress plugins. This skill acts as a senior Gutenberg engineer, handling the complex decision-making involved in modern block development. It eliminates the trial-and-error of setup, ensuring your blocks are architecturally sound, accessible, and performant from the first line of code.

    What it does

    • Complete Plugin Scaffolding: Generates the entire folder tree, including block.json (apiVersion 3), package.json with @wordpress/scripts, PHP bootstraps, and React components.
    • Architectural Logic: Automatically decides between static (save.js) and dynamic (render.php) rendering based on your block's data needs.
    • Senior-Level Review: Audits existing block code for deprecation safety, XSS vulnerabilities through improper escaping, and accessibility compliance.
    • Advanced Features: Implements InspectorControls, InnerBlocks, Interactivity API modules, and native supports for colors, spacing, and typography.

    Why use this skill?

    Prompting a generic AI often results in outdated tutorials or broken save functions that lead to "Block Validation" errors. This skill follows the WordPress Core standards: it uses apiVersion 3, handles i18n properly, ensures strict data escaping in PHP, and structures deprecations so your users' content never breaks. You get a professional-grade codebase that passes plugin directory reviews, not just a snippet.

    Supported Workflows

    • Build Mode: Describe a block (e.g., "A dynamic testimonial slider") and get the full installable ZIP-ready code.
    • Review Mode: Paste your src/ folder or block.json to receive a scored audit and before-after fixes.

    Use Cases

    • Scaffold installable block plugins with @wordpress/scripts build setups.
    • Convert legacy shortcodes into modern Gutenberg blocks with proper attributes.
    • Audit block code for deprecation safety to prevent 'Invalid Content' errors.
    • Implement dynamic blocks using render.php with secure data escaping.
    • Add accessibility-compliant keyboard navigation and ARIA roles to custom blocks.
