Cursor Project Rules enhance Cursor AI editor behavior with project-specific guidance and reusable coding standards.
Cursor AI is an AI-powered code editor. Cursor Project Rules are Markdown-based .mdc files that live in .cursor/rules/ and tell Cursor how to behave for specific projects, file types, frameworks, and workflows.
Cursor rules help developers define project-specific instructions for Cursor AI. This repository uses the modern .mdc Project Rules format.
Customized behavior means Cursor can respond to the specific needs of a project instead of relying only on general coding knowledge. Rules can describe local architecture, preferred libraries, common methods, domain constraints, and other context that makes generated code more relevant.
Consistency is the other big win. By defining coding standards and best practices in .mdc files, teams can guide Cursor toward code that matches the project's style, naming, structure, and review expectations.
Project rules also reduce repeated manual editing. Well-scoped rules give Cursor reusable project knowledge up front, so suggestions are more likely to fit the codebase on the first pass and less likely to need the same corrections again.
For teams, shared .cursor/rules/*.mdc files keep AI assistance aligned across contributors. Everyone can work from the same project-specific guidance, whether the rule covers framework usage, security requirements, testing conventions, or workflow details.
By adding selected .mdc files to .cursor/rules/, you can use these rules directly in your project.
