Cursor Directory — Community Cursor Rules & AI Prompts

What it is

Cursor Directory is a community-curated website that collects and organizes Cursor rules, AI coding prompts, and MCP configurations. Users can browse rules by framework (React, Python, Go, Next.js, etc.), preview the rule content, and copy it into their project .cursorrules file with a single click. The directory also includes AI prompt templates for common development tasks.

Developers using Cursor IDE who want to improve their AI coding assistant behavior, teams standardizing AI coding rules across projects, and anyone looking for well-crafted system prompts for code generation use Cursor Directory as their reference.

How it saves time or tokens

Writing effective .cursorrules files requires understanding how to instruct AI coding assistants for specific frameworks and coding styles. Cursor Directory provides pre-tested rules that encode best practices, naming conventions, and framework-specific patterns. Instead of iterating on your own rules, you start with community-validated configurations that produce better code generation results immediately.

How to use

1. Visit cursor.directory
2. Browse rules by framework or search for your technology stack.
3. Click 'Copy' on any rule you want to use.
4. Paste the content into your project .cursorrules file:

# Create or edit your .cursorrules file
touch .cursorrules
# Paste the copied rule content

1. Cursor IDE automatically reads .cursorrules and applies the instructions to all AI interactions.

Example

# Example .cursorrules content (React + TypeScript)

You are an expert in TypeScript, React, Next.js 14, and Tailwind CSS.

Key principles:
- Write concise, technical TypeScript code with accurate examples
- Use functional and declarative programming patterns
- Prefer iteration and modularization over code duplication
- Use descriptive variable names with auxiliary verbs

Naming conventions:
- Use lowercase with dashes for directories (e.g., components/form-wizard)
- Favor named exports for components
- Use PascalCase for component files

TypeScript usage:
- Use TypeScript for all code; prefer interfaces over types
- Avoid enums; use const maps instead
- Use functional components with TypeScript interfaces for props

Common pitfalls

• Rules that are too long or too specific can constrain the AI and produce worse results. Keep rules focused on coding patterns and conventions rather than step-by-step instructions.
• Framework-specific rules should be updated when framework versions change. Rules written for Next.js 13 may not produce correct code for Next.js 14.
• Combining rules from multiple sources without review can create contradictions. Test your .cursorrules file after modifications to ensure consistent behavior.
