💡 What is .cursorrules?
.cursorrules is a configuration file that tells Cursor AI your coding standards, project conventions, and preferences. It helps the AI generate code that matches your team's style and requirements. Place the file in your project root and Cursor will automatically follow your rules.
Frequently Asked Questions
Where do I put the .cursorrules file?
Place the .cursorrules file in your project root directory (same level as package.json, tsconfig.json, etc.). Cursor will automatically detect and use it.
What's the difference between .cursorrules and CLAUDE.md?
.cursorrules is for coding-specific rules (syntax, patterns, conventions). CLAUDE.md is for broader project context (architecture, goals, workflows). Use both for best results.
Can I use this with Claude Code or Copilot?
The .cursorrules format is specific to Cursor. However, you can adapt the content for CLAUDE.md (Claude Code) or .github/copilot-instructions.md (GitHub Copilot).
How do I update my rules over time?
Start with basic rules and refine as you learn what works. Add new rules when you encounter repeated issues or establish new conventions. Keep the file focused - too many rules can be overwhelming.
