    WordPress Plugin Engineering

    Example session with this skill installed

    I have a half-finished plugin at wp-content/plugins/event-sync/event-sync.php that syncs event data to an external endpoint daily. Review and harden it: activation and uninstall look suspect, the options page saves raw POST data with no nonce, and the cron job never gets cleared on deactivation. Target WordPress 6.9, PHP 7.4, single site. Fix the security issues, make uninstall conservative so it only removes data the plugin owns, keep the settings screen working, and package a 1.1.0 release ZIP with an updated readme.txt.

    Summary

    Audited event-sync for lifecycle safety, input handling, and scheduling, applied fixes, and packaged a 1.1.0 release archive.

    Next steps

    • Install the ZIP on staging and confirm the options page saves and renders correctly
    • Activate/deactivate once, then run wp cron event list to verify the event is cleared
    • Regenerate languages/event-sync.pot if new user-facing strings were added

    About this skill

    The problem

    Building WordPress plugins often results in messy hook registration, insecure data handling, and incomplete lifecycle routines. Developers struggle to implement the Settings API correctly or fail to clean up data upon uninstallation, leading to technical debt and repository rejection.

    What it does

    • Generates predictable, namespaced plugin structures with separated admin and frontend logic.
    • Implements secure activation, deactivation, and uninstall routines that handle multisite and custom tables.
    • Scaffolds Settings API screens with built-in sanitization, validation, and nonce protection.
    • Architects idempotent WP-Cron tasks with locking mechanisms for safe background processing.
    • Applies strict security patterns for SQL preparation, output escaping, and capability checks.

    Frameworks & tools

    PHP 7.2+, WordPress Core API, WP-CLI, and standard WordPress plugin headers. Works with standard LAMP/LEMP stacks and local development environments like Local or DevKinsta.

    Why this beats prompting it yourself

    Standard LLMs often suggest deprecated hooks or omit critical security steps like check_admin_referer. This skill enforces a production-ready directory layout and ensures data persistence follows dbDelta and $wpdb best practices, preventing common bugs in multisite environments.

    Use cases

    • Architecting a new feature-rich plugin from a clean bootstrap.
    • Hardening an existing plugin for submission to the WordPress.org repository.
    • Adding background processing or scheduled cleanup tasks to a legacy codebase.
    • Refactoring procedural plugin code into a maintainable, object-oriented structure.

    Known limitations

    Does not provide specialized boilerplate for Block Editor (Gutenberg) components or WooCommerce-specific extension classes. Requires manual execution of build scripts for JS/CSS assets.

    Find more skills like this on the Claude Skills Marketplace, the Codex Skills Marketplace and the Gemini Skills Marketplace, or browse Claude Skills for WordPress and WooCommerce.

    Covers standard hook-based plugins only — block-only plugins, WooCommerce-specific APIs, and hosting deployment pipelines are out of scope. Assumes WordPress 6.x and PHP 7.2+ conventions.

    Frequently Asked Questions

    This skill generates production-ready WordPress plugin architectures, specifically addressing complex requirements like secure Settings API implementation, idempotent WP-Cron tasks, and robust uninstall routines that many developers struggle to get right manually.

    The skill supports PHP 7.2 and higher, adhering to the latest WordPress Core API standards. It is compatible with all major AI agents that support code generation and can be integrated into local development environments like Local, DevKinsta, or WP-CLI workflows.

    Yes, the skill is designed with WordPress.org repository standards in mind, enforcing strict security patterns such as nonce verification, capability checks, and proper data escaping to help your code pass the plugin review process.

    While it excels at backend logic and admin settings, it does not currently generate React-based Gutenberg block components or specific WooCommerce integration classes; it focuses on the core plugin foundation and lifecycle.

    You receive the specialized AI logic for scaffolding namespaced plugin structures, secure hook registration, and database management routines, allowing you to generate unlimited clean-code foundations for your projects.

    The skill follows dbDelta and $wpdb best practices to ensure that database schema updates and data persistence are handled safely, including specific logic for multisite environments to prevent data leakage between sites.
