Cursor Rules Starter Pack — Free

Stop Cursor from Writing Bad Code

Out of the box, Cursor generates code with sloppy patterns — any types everywhere, useEffect for data fetching, no error handling, and random debugging advice.

One file fixes that.

What's Inside

Drop a single .cursorrules file into your project and Cursor immediately follows better patterns:

⚛️ React Component Patterns

• Server Components by default
• Typed props with interfaces
• No unnecessary useEffect
• Proper hooks patterns

🔷 Type Safety Essentials

• Ban any — use unknown with type guards
• Discriminated unions for state
• Type guards over assertions
• Explicit return types

🐛 Systematic Debugging

• Reproduce → Isolate → Diagnose → Fix → Prevent
• Common error pattern cheat sheet
• Root cause analysis, not symptom patching
• Setup (30 seconds)
• Download the zip
• Copy .cursorrules to your project root
• Open Cursor and start coding
• No config. No extensions. No plugins.
