SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This Skill eliminates the complexity and security risks of WordPress plugin development, preventing 20+ documented vulnerabilities while saving 67% development time.

Core Features & Use Cases

  • Security Foundation: Automatically implements nonces, sanitization, escaping, and prepared statements to prevent SQL injection, XSS, and CSRF attacks.
  • Use Case: When creating a new booking plugin, use this Skill to generate a secure, standards-compliant codebase with built-in protection against common vulnerabilities.

Quick Start

Create a new WordPress plugin called 'my-booking-system' with OOP architecture and GitHub auto-updates enabled.

Architecture Patterns

  • Simple: Functional programming for small plugins (<5 functions)
  • OOP: Object-oriented singleton pattern for medium plugins
  • PSR-4: Modern namespaced architecture with Composer autoloading.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I prevent SQL injection and XSS attacks when building a WordPress plugin?▼

WordPress plugins require input sanitization, output escaping, and prepared statements to prevent SQL injection and XSS. This Skill automatically implements these protections along with nonce verification and capability checks across Simple, OOP, and PSR-4 architectures, eliminating 20+ documented vulnerabilities.

What's the best way to structure a secure WordPress plugin with REST API endpoints?▼

Secure REST endpoints require nonce verification, capability checks, and proper input validation. This Skill generates production-ready REST implementations with built-in security, custom post types, and AJAX handling across functional and object-oriented patterns.

Do I need to manually implement WordPress security best practices like prefixing and nonce verification?▼

WordPress security requires unique prefixing, ABSPATH checks, nonce verification, and uninstall cleanup. This Skill automates these across activation lifecycles and Settings API usage, saving 67% development time while ensuring compliance with WordPress security standards.

How do I choose between Simple, OOP, and PSR-4 architecture for my WordPress plugin?▼

Simple architecture suits small plugins under 5 functions; OOP uses singleton patterns for medium complexity; PSR-4 provides modern namespaced architecture with Composer autoloading. This Skill supports all three, letting you select based on plugin scope and team preferences.

Can I use this approach for plugins with custom post types and Settings API integration?▼

Yes. This Skill handles custom post types, Settings API configuration, and AJAX handlers with built-in sanitization and escaping. It applies security patterns across activation, operation, and uninstall lifecycle stages.

What security vulnerabilities does automated WordPress plugin generation prevent?▼

Automated generation prevents SQL injection, XSS, CSRF, improper capability checks, and missing nonce verification. This Skill applies 20+ documented vulnerability protections through standardized sanitization, escaping, and prepared statement patterns.
