The instructions your agent reads when the skill is triggered.
WooCommerce Development
You are an expert in WordPress and WooCommerce development, PHP best practices, and e-commerce solutions.
Core Principles
- Follow WordPress coding standards
- Use WooCommerce hooks and filters properly
- Prioritize security in all code
- Maintain backwards compatibility
- Write performant, scalable code
PHP Best Practices
Coding Standards
- Follow WordPress PHP Coding Standards
- Use meaningful function and variable names
- Prefix all functions and classes to avoid conflicts
- Document code with PHPDoc comments
Namespacing
namespace MyPlugin\WooCommerce;
class ProductHandler {
public function __construct() {
add_action('woocommerce_before_add_to_cart_form', [$this, 'custom_content']);
}
public function custom_content() {
// Custom functionality
}
}
WooCommerce Hooks
Action Hooks
// Add content after product summary
add_action('woocommerce_after_single_product_summary', 'custom_product_content', 15);
function custom_product_content() {
echo '<div class="custom-content">Additional information</div>';
}
// Modify order processing
add_action('woocommerce_order_status_completed', 'process_completed_order', 10, 1);
function process_completed_order($order_id) {
$order = wc_get_order($order_id);
// Process order
}
Filter Hooks
// Modify product price display
add_filter('woocommerce_get_price_html', 'custom_price_html', 10, 2);
function custom_price_html($price, $product) {
if ($product->is_on_sale()) {
$price .= '<span class="sale-badge">Sale!</span>';
}
return $price;
}
// Add custom checkout fields
add_filter('woocommerce_checkout_fields', 'custom_checkout_fields');
function custom_checkout_fields($fields) {
$fields['billing']['billing_custom_field'] = [
'type' => 'text',
'label' => __('Custom Field', 'textdomain'),
'required' => false,
'priority' => 25,
];
return $fields;
}
Security
Data Validation
// Sanitize input
$product_id = absint($_POST['product_id']);
$quantity = wc_stock_amount($_POST['quantity']);
$email = sanitize_email($_POST['email']);
// Escape output
echo esc_html($product->get_name());
echo esc_url($product->get_permalink());
echo wp_kses_post($product->get_description());
Nonce Verification
// Create nonce
wp_nonce_field('custom_action', 'custom_nonce');
// Verify nonce
if (!wp_verify_nonce($_POST['custom_nonce'], 'custom_action')) {
wp_die(__('Security check failed', 'textdomain'));
}
Capability Checks
if (!current_user_can('manage_woocommerce')) {
wp_die(__('Unauthorized access', 'textdomain'));
}
Custom Product Types
class WC_Product_Custom extends WC_Product {
public function get_type() {
return 'custom';
}
// Custom methods
}
add_filter('product_type_selector', function($types) {
$types['custom'] = __('Custom Product', 'textdomain');
return $types;
});
REST API Extensions
add_action('rest_api_init', function() {
register_rest_route('custom/v1', '/products/featured', [
'methods' => 'GET',
'callback' => 'get_featured_products',
'permission_callback' => '__return_true',
]);
});
function get_featured_products($request) {
$args = [
'status' => 'publish',
'featured' => true,
'limit' => 10,
];
$products = wc_get_products($args);
return rest_ensure_response($products);
}
Database Operations
global $wpdb;
// Use prepare for queries with variables
$results = $wpdb->get_results($wpdb->prepare(
"SELECT * FROM {$wpdb->prefix}wc_orders WHERE status = %s",
'completed'
));
// Use WooCommerce data stores when possible
$product = new WC_Product();
$product->set_name('New Product');
$product->set_regular_price('29.99');
$product->save();
Performance
- Use transients for caching
- Optimize database queries
- Lazy load when possible
- Minimize HTTP requests
- Use object caching
Caching
$cached_data = get_transient('custom_product_data');
if (false === $cached_data) {
$cached_data = expensive_query();
set_transient('custom_product_data', $cached_data, HOUR_IN_SECONDS);
}

Popular backend & apis skills
find-skills
vercel-labs/skills
Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.
entra-app-registration
microsoft/azure-skills
Guides Microsoft Entra ID app registration, OAuth 2.0 authentication, and MSAL integration. USE FOR: create app registration, register Azure AD app, configure OAuth, set up authentication, add API permissions, generate service principal, MSAL example, console app auth, Entra ID setup, Azure AD authentication. DO NOT USE FOR: Key Vault secrets (use azure-keyvault-expiration-audit), general Azure resource security guidance.
google-agents-cli-adk-code
google/agents-cli
This skill should be used when the user wants to "write agent code", "build an agent with ADK", "add a tool", "create a callback", "define an agent", "use state management" — in a project that needs ADK (Agent Development Kit) API patterns and code examples. It provides a quick reference for agent types, tool definitions, orchestration patterns, callbacks, state management, the graph Workflow API, and reference recipes to study. Do NOT use for scaffolding (use google-agents-cli-scaffold) or deployment (use google-agents-cli-deploy).
embedded-captions
heygen-com/hyperframes
Add captions or subtitles to an existing single-subject talking-head video without editing the footage. Use for plain verbatim captions, cinematic captions embedded behind the subject, VFX captions, “炸/特效/酷炫字幕,” or a named identity from the 35-style catalog. Route by visual identity, not by backend engine. The quiet anchor rail is the default; embed every word only when the user explicitly wants a fully cinematic treatment. The workflow runs locally end to end, including transcription and subject matting; split multi-shot footage before applying it.
entra-agent-id
