AI Agent Skill: Master WordPress Capability & Permission Checks

AI Agent Skill: Master WordPress Capability & Permission Checks

This AI agent skill assists developers by gating actions in WordPress with capability checks using current_user_can(). It ensures actions are authorized by verifying specific capabilities and pairing them with nonces, preventing privilege escalation and broken access control.

What this skill does

• Implements capability checks, verifying permissions for actions like adding admin pages, menu items, and AJAX/REST handlers.
• Pairs capability checks with nonces to confirm the request origin.
• Uses object-specific capability verification (e.g., edit_post for a particular post) to maintain precision in checks.
• Encourages proactive application of checks to every privileged code path within WordPress.

Who it is for

This skill is ideal for developers and teams using AI coding agents such as Claude Code, Cursor, and Codex who require enhanced authorization management for WordPress development.

Use cases

• Developing or maintaining WordPress admin menu/submenu pages and settings screens that need restricted access.
• Securing AJAX operations (wp_ajax_*) and REST API endpoints through capability checks.
• Managing actions like editing options, users, posts, taxonomies, or plugin states where precise permission checks are necessary.
• Ensuring any code that reads or writes another user's data is appropriately gated and verified.

Technical details

• Utilizes AI agent tools such as agent-skills, aiapplication, and capability-permission-checks for implementation.
• Establishes a distinction between authorization checks and nonce verification for secure request validation.
• Avoids role-level checks like current_user_can('administrator') in favor of specific capabilities for accuracy and customization.
