WordPress.org has updated its Plugin Check plugin for WordPress developers worldwide. The latest listed version, 1.9.0, adds AI connector support and additional automated checks. The tool is available from the official Plugin Check (PCP) By WordPress.org listing.
Official WordPress Plugin Checker: Key details
Plugin Check, maintained by WordPress.org contributors, is designed for plugin authors. According to its directory description, it runs many of the same automated checks used for new plugin submissions, focusing on coding standards, use of WordPress APIs, and compliance with directory rules.
Core capabilities currently highlighted on the directory page include:
- Automated scanning of plugin code for issues in internationalization, accessibility, performance, and security.
- Flagging of potential problems that may prevent approval in the official WordPress.org plugin directory.
- A Plug Namer feature that checks whether a plugin name is too generic or conflicts with existing plugins and trademarks.
According to the WordPress.org listing, version 1.9.0 introduces the following changes:
- Support for new WordPress 7.0 AI connectors, allowing integration with the platform's AI infrastructure during plugin analysis.
- Updated block compatibility checks targeting WordPress 7.0.
- New detection of external URLs in top-level admin menus that could lead to unexpected admin behavior.
- Additional smaller code and performance adjustments recorded in the release notes.
The tool flags violations and other concerns in plugin development, including incorrect use of internationalization functions and issues involving accessibility, performance, or security. Its primary goal is to confirm whether plugins meet the stated requirements of the WordPress.org plugin directory.
Background context
Plugin Check builds on long-running efforts within the WordPress ecosystem to standardize plugin review processes. It sits alongside tools such as the Theme Check plugin and WordPress coding standards for PHP_CodeSniffer. Together, these resources address security, performance, and accessibility requirements across the plugin directory.
The Plugin Check directory page also features user reviews describing practical outcomes from running the tool. One reviewer reports that the plugin highlighted areas they believed were already fixed, and that repeated scans eventually cleared all errors. Another review describes Plugin Check as a:
"useful tool for catching issues early" for serious plugin development work.
