Frequently Asked Questions

What is a .cursorrules file?

A .cursorrules file is a project-level configuration file for Cursor AI. It defines coding standards, language preferences, framework conventions, and behavioural rules that Cursor follows when generating or editing code. Place it in your project root and Cursor automatically applies the rules to every AI-assisted action.

Where do I put the .cursorrules file?

Place the .cursorrules file in the root directory of your project — next to package.json, pyproject.toml, or Cargo.toml. Cursor detects it automatically when you open the project. For more granular control, you can also use the .cursor/rules/ directory for folder-specific rules.

Do .cursorrules work with all programming languages?

Yes. Cursor rules are language-agnostic — they work with TypeScript, JavaScript, Python, Go, Rust, Java, C#, and any other language Cursor supports. The rules define conventions and coding standards that Cursor applies regardless of language.

Can I share .cursorrules across a team?

Absolutely. Commit the .cursorrules file to your repository so every team member gets the same AI coding standards. This ensures consistent code generation across your entire team — much like .editorconfig or .eslintrc enforces formatting and linting rules.
