For a long time, WordPress has had the theme check plugin, a tool which statically analyzes a given WordPress theme to determine if it follows certain theme development requirements and best practices.
This post proposes defining and implementing a similar tool for WordPress plugins that analyzes a given WordPress plugin and flags any violations of plugin development requirements and best practices with errors or warnings. It should cover various aspects of plugin development, from basic requirements like correct usage of internationalization functions to accessibility, performance, and security best practices.
This post is based on an earlier proposal document that has been reviewed and discussed by the performance working group over the last several weeks (see original Slack message sharing the proposal).
