wp-hooks-ref

/wp-hooks-ref

Look up WordPress and WooCommerce hooks by name or topic.

Instructions

Load the wp-hooks skill for hook documentation methodology.

The user provides a hook name, partial name, or topic after /wp-hooks-ref. For example:

• /wp-hooks-ref save_post — Show the save_post hook details
• /wp-hooks-ref woocommerce_checkout — List hooks matching "woocommerce_checkout"
• /wp-hooks-ref auth — Search for authentication-related hooks

Behavior

1. Exact match: If the argument matches a known hook name exactly, provide:

   • Hook type (action or filter)
   • Function signature with parameters and types
   • When it fires (context)
   • Common use cases with code examples
   • Related hooks

2. Partial match / prefix: If the argument is a prefix (e.g., woocommerce_), list all matching hooks from the plugin's reference files, grouped by category.

3. Topic search: If the argument is a general topic (e.g., "auth", "login", "media"), search for related hooks and present them organized by relevance.

Reference Sources

First check the plugin's built-in references:

• skills/woocommerce/references/woo-hooks.md for WooCommerce hooks
• skills/wordpress-patterns/SKILL.md for common WordPress patterns

For hooks not covered in the local references, use your built-in knowledge of the WordPress hook system. Only use WebSearch as a last resort for very specific or rarely-used hooks.

Output Format

For each hook, provide:

## hook_name (action|filter)

**Signature:** `do_action( 'hook_name', $param1, $param2 )` or `apply_filters( 'hook_name', $value, $context )`

**Parameters:**
- `$param1` (type) — Description
- `$param2` (type) — Description

**Fires:** Description of when this hook fires.

**Example:**
