This project provides a custom ESLint plugin for the Egg.js framework, designed to catch common mistakes made by developers, particularly those related to RTFM (Read The Fine Manual) issues. It includes rules like `no-override-exports`, `no-unexpected-plugin-keys`, and `no-only-tests` to enforce best practices and prevent errors in Egg.js applications. The plugin is aimed at Egg.js developers who want to maintain code quality and avoid common pitfalls during development.
