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.

• Why Cursor Rules
• Rules
  • Frontend Frameworks and Libraries
  • Backend and Full-Stack
  • Mobile Development
  • Games and Graphics
  • CSS and Styling
  • State Management
  • Database and API
  • Testing
  • Hosting and Deployments
  • Build Tools and Development
  • Language-Specific
  • Security
  • Documentation
• Directories
• How to Use

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.

• CursorDirectory

1. Install Cursor AI if you haven't already.
2. Browse the rules above to find an .mdc rule that suits your needs.
3. Create a .cursor/rules/ directory in your project if it does not already exist.
4. Copy the chosen .mdc file into .cursor/rules/.
5. Customize the rule as needed for your specific project requirements.

Contributions are welcome! If you have a great Cursor rule to share:

1. Fork this repository.

2. Choose a descriptive slug for the rule, such as react-typescript or python-fastapi.

3. Add the canonical .mdc rule under rules/.

4. New rules/*.mdc files must start with frontmatter like this:

   ---
   description: One-line summary of what this rule helps Cursor do
   globs: **/*.ts, **/*.tsx
   alwaysApply: false
   ---

   The description field explains the rule's purpose to Cursor and contributors. The globs field lists the file patterns where the rule should auto-attach. Use alwaysApply: false to keep the rule scoped to matching or requested context, and use alwaysApply: true only for universal guidance that should apply to every request.

5. Update the main README.md file, adding your contribution to the appropriate category.

6. Ensure your contribution follows the repository formatting and naming guidelines.

7. Submit a pull request.

Please ensure your contribution is original or properly credited if based on existing work. Keep descriptions neutral, practical, and focused on reusable Cursor rule value.
