WordPress plugin development with hooks, security, REST API, custom post types. Use for plugin creation, $wpdb queries, Settings API, or encountering SQL injection, XSS, CSRF, nonce errors.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# WordPress Plugin Development (Core)
**Status**: Production Ready
**Last Updated**: 2026-08-03
**Dependencies**: None (WordPress 6.0+, PHP 8.0+)
**Latest Versions**: WordPress 7.0+, PHP 8.3+ recommended
---
## Quick Start (10 Minutes)
### 1. Choose Plugin Structure
Three architecture patterns available (see `references/plugin-architectures.md` for detailed examples):
- **Simple** (functions only) - Small plugins <5 functions
- **OOP** - Medium plugins with related functionality
- **PSR-4** (Namespaced + Composer) - Modern standard (2025), most maintainable
### 2. Create Plugin Header
Every plugin MUST have a header comment in the main file:
```php
<?php
/**
* Plugin Name: My Awesome Plugin
* Description: Brief description.
* Version: 1.0.0
* Requires at least: 6.0
* Requires PHP: 8.0
* Text Domain: my-plugin
*/
if ( ! defined( 'ABSPATH' ) ) exit;
```
**CRITICAL**: Plugin Name is required, Text Domain must match plugin slug exactly.
### 3. Security Foundation (5 Essentials)
```php
// 1. Unique Prefix (4-5 chars)
function mypl_init() { /* code */ }
add_action( 'init', 'mypl_init' );
// 2. ABSPATH Check (every file)
…Read the whole file at its exact version.
How to install
mdr add secondsky/claude-skills/wordpress-plugin-core@sha256:3aae52011ec199feThe line at the top of this page pins the label git:20260803.0b1c48d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
