Take AI Coding Productivity to the Top: A Guide to Creating .cursorrules & CLAUDE.md
Originally published in Turkish. Read the original →
A guide to eliminating hallucinations and faulty code generation by defining project-specific architecture rules in the Cursor, Windsurf and Claude Code editors.
The most common scenario when coding with AI assistants goes like this: you write the prompt, the model produces a great-looking block of code; but when you try to run it, you notice it imports a package that doesn't exist in your project at all, uses a deprecated function, or builds a structure that completely violates the company's architectural principles.
When you're "Vibe Coding" or working with autonomous agents, this makes you lose time instead of saving it. The solution is very clear: give the AI a rules manifesto that explains your project's boundaries and laws.
The .cursorrules Generator plugin on our website was built precisely so you can prepare this rules manifesto in minutes.

What Should an AI Rules File Contain?
A successful .cursorrules or CLAUDE.md file is built on 5 main pillars:
┌────────────────────────────────────────────────────────┐
│ 1. Project & Architecture Summary │
├────────────────────────────────────────────────────────┤
│ 2. Strict Type and Language Rules │
├────────────────────────────────────────────────────────┤
│ 3. Folder and Module Hierarchy │
├────────────────────────────────────────────────────────┤
│ 4. Security and Error Handling │
├────────────────────────────────────────────────────────┤
│ 5. Testing and Documentation Rules │
└────────────────────────────────────────────────────────┘1. Project & Architecture Summary
It should clearly state which framework, which package manager (pnpm, bun, npm) and which design system the project is built on.2. Strict Type and Language Standards
This section is where you stop the model from falling back on theany type when using TypeScript and make the distinction between interface and type clear.3. Folder and Module Hierarchy
It defines which directory a new component, utility function or data model should be saved to when it is added.4. Security and Error Handling
It sets the standards for validating user input (Zod, Joi, etc.), reading environment variables securely and logging errors.---
Save Time With the .cursorrules Generator
Writing these rules from scratch in every new repo or project is tedious. Using our .cursorrules Generator plugin, you can:
- Select your project's characteristics with checkboxes,
- Move quickly using ready-made templates (Next.js Enterprise, Full-Stack Python, Microservices, etc.),
- Get the output in
CLAUDE.md,.cursorrulesor.windsurfrulesformat with a single click.

Comparative Developer Experience
| Situation | Without a Rules File | With the .cursorrules Generator |
|---|---|---|
| Deprecated Code Risk | High | Zero |
| Package Consistency | Wrong library dependencies | Only packages installed in the project |
| Code Review Time | Long and exhausting | Fast and standards-compliant |
| Prompt Length | 30 lines of explanation every time | A single goal-focused sentence |
Protect Your Codebase
