What are Cursor Rules?

Cursor rules (stored in a .cursorrules file) are instructions that tell the Cursor AI coding assistant how to write code for your specific project. They define coding conventions, architectural patterns, error handling approaches, and best practices that the AI should follow when generating or modifying code.

Without cursor rules, AI assistants generate generic code that doesn't match your team's standards. With good cursor rules, every AI-generated snippet follows your exact patterns — from file naming to error handling to test structure.

Our rules are written by senior engineers who use these frameworks daily in production. They cover not just syntax preferences, but architectural decisions, performance patterns, and security practices that generic rules miss entirely.
