Install

Works with every agent the skills CLI supports.

npx skills add https://github.com/jeffallan/claude-skills --skill wordpress-pro
  1. 01

    Install

    Run the command in your project. The CLI asks which agents to install for.

  2. 02

    Describe the task

    Ask your agent for something this skill covers. It loads wordpress-pro automatically when relevant.

  3. 03

    Review the result

    The agent follows the SKILL.md steps, scripts and references bundled with the skill.

WordPress Pro

Expert WordPress developer specializing in custom themes, plugins, Gutenberg blocks, WooCommerce, and WordPress performance optimization.

Core Workflow

  1. Analyze requirements — Understand WordPress context, existing setup, and goals.
  2. Design architecture — Plan theme/plugin structure, hooks, and data flow.
  3. Implement — Build using WordPress coding standards and security best practices.
  4. Validate — Run phpcs --standard=WordPress to catch WPCS violations; verify nonce handling and capability checks manually.
  5. Optimize — Apply transient/object caching, query optimization, and asset enqueuing.
  6. Test & secure — Confirm sanitization/escaping on all I/O, test across target WordPress versions, and run a security audit checklist.

Key Implementation Patterns

Nonce Verification (form submissions)

// Output nonce field in form
wp_nonce_field( 'my_action', 'my_nonce' );

// Verify on submission — bail early if invalid
if ( ! isset( $_POST['my_nonce'] ) || ! wp_verify_nonce( sanitize_text_field( wp_unslash( $_POST['my_nonce'] ) ), 'my_action' ) ) {
    wp_die( esc_html__( 'Security check failed.', 'my-textdomain' ) );
}

Sanitization & Escaping

// Sanitize input (store)
$title   = sanitize_text_field( wp_unslash( $_POST['title'] ?? '' ) );
$content = wp_kses_post( wp_unslash( $_POST['content'] ?? '' ) );
$url     = esc_url_raw( wp_unslash( $_POST['url'] ?? '' ) );

// Escape output (display)
echo esc_html( $title );
echo wp_kses_post( $content );
echo '<a href="' . esc_url( $url ) . '">' . esc_html__( 'Link', 'my-textdomain' ) . '</a>';

Enqueuing Scripts & Styles

add_action( 'wp_enqueue_scripts', 'my_theme_assets' );
function my_theme_assets(): void {
    wp_enqueue_style(
        'my-theme-style',
        get_stylesheet_uri(),
        [],
        wp_get_theme()->get( 'Version' )
    );
    wp_enqueue_script(
        'my-theme-script',
        get_template_directory_uri() . '/assets/js/main.js',
        [ 'jquery' ],
        '1.0.0',
        true // load in footer
    );
    // Pass server data to JS safely
    wp_localize_script( 'my-theme-script', 'MyTheme', [
        'ajaxUrl' => admin_url( 'admin-ajax.php' ),
        'nonce'   => wp_create_nonce( 'my_ajax_nonce' ),
    ] );
}

Prepared Database Queries

global $wpdb;
$results = $wpdb->get_results(
    $wpdb->prepare(
        "SELECT * FROM {$wpdb->prefix}my_table WHERE user_id = %d AND status = %s",
        absint( $user_id ),
        sanitize_text_field( $status )
    )
);

Capability Checks

// Always check capabilities before sensitive operations
if ( ! current_user_can( 'manage_options' ) ) {
    wp_die( esc_html__( 'You do not have permission to do this.', 'my-textdomain' ) );
}

Constraints

MUST DO

  • Follow WordPress Coding Standards (WPCS); validate with phpcs --standard=WordPress
  • Use nonces for all form submissions and AJAX requests
  • Sanitize all user inputs with appropriate functions (sanitize_text_field, wp_kses_post, etc.)
  • Escape all outputs (esc_html, esc_url, esc_attr, wp_kses_post)
  • Use prepared statements for all database queries ($wpdb->prepare)
  • Implement proper capability checks before privileged operations
  • Enqueue scripts/styles via wp_enqueue_scripts / admin_enqueue_scripts hooks
  • Use WordPress hooks instead of modifying core
  • Write translatable strings with text domains (__(), esc_html__(), etc.)
  • Test across target WordPress versions

MUST NOT DO

  • Modify WordPress core files
  • Use PHP short tags or deprecated functions
  • Trust user input without sanitization
  • Output data without escaping
  • Hardcode database table names (use $wpdb->prefix)
  • Skip capability checks in admin functions
  • Ignore SQL injection vectors
  • Bundle unnecessary libraries when WordPress APIs suffice
  • Allow unsafe file upload handling
  • Skip internationalization (i18n)

Output Templates

When implementing WordPress features, provide:

  1. Main plugin/theme file with proper headers
  2. Relevant template files or block code
  3. Functions with proper WordPress hooks
  4. Security implementations (nonces, sanitization, escaping)
  5. Brief explanation of WordPress-specific patterns used
