SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill identifies potential security vulnerabilities, performance bottlenecks, and adherence to WordPress coding standards within custom WordPress themes and plugins.

Core Features & Use Cases

Automated Code Auditing: Scans custom PHP and JavaScript files for common anti-patterns, deprecated functions, and security risks like SQL injection or missing sanitization.
AI-driven Contextual Analysis: Goes beyond simple pattern matching to understand code logic and identify deeper architectural or security flaws.
Use Case: A developer can use this Skill to quickly audit a custom plugin before deploying it to a live site, ensuring it's secure, performant, and follows WordPress best practices.

Quick Start

Run a comprehensive code quality diagnostic on the active theme and custom plugins.

FAQPage Schema

How do I audit custom WordPress plugins for security vulnerabilities and deprecated functions?▼

WordPress code quality analysis detects security vulnerabilities by scanning custom PHP and JavaScript files for missing nonce verification, hardcoded credentials, and SQL injection risks. It goes beyond simple pattern matching to understand code logic and identify deeper architectural flaws.

What is the best way to check WordPress theme code for missing sanitization and SQL injection risks?▼

A two-pass AI analysis approach is best for checking WordPress theme code, combining initial pattern scanning with deep contextual review. This method accurately identifies missing sanitization, SQL injection risks, and deeper architectural flaws in custom themes.

Does automated code quality analysis detect hardcoded credentials and nonce verification issues in PHP?▼

Yes, automated code quality analysis detects hardcoded credentials and missing nonce verification in custom PHP files. It utilizes AI-driven contextual analysis to locate these specific security risks and flags them for review before deployment.

Can I scan custom JavaScript files for performance bottlenecks and WordPress coding standards violations?▼

Yes, you can scan custom JavaScript files alongside PHP to identify performance bottlenecks and WordPress coding standards violations. The analysis evaluates your custom code for common anti-patterns and deeper architectural issues.

When do I need AI contextual analysis for WordPress code auditing instead of simple pattern matching?▼

You need AI contextual analysis when simple pattern matching cannot understand complex code logic or identify deeper architectural flaws in custom plugins. It is essential for uncovering subtle security vulnerabilities and performance bottlenecks that basic automated scanning misses.
