Software development is undergoing a significant transformation with the arrival of generative AI tools. Among these tools, Cursor stands out as one of the most powerful, especially with its Agents functionality.

While Rules define standards and Agents execute complex tasks, Commands are reusable workflows that standardize common processes. They transform repetitive tasks into simple commands with the / prefix.

One of Cursor's most powerful features is Rules. They allow you to create persistent instructions that guide the Agent's behavior, ensuring consistency, standardization, and complete customization of your development experience.

A complete guide to best practices for development with Cursor AI. Copy and paste the rules below into your .cursorrules file to enhance your development experience.

Many JavaScript developers make a common mistake: doing mathematical calculations directly with the language's native operations. This can cause serious precision problems, especially in financial or scientific applications.

Many people ask me how to organize their studies in technology. There's no single path, but it's possible to think in learning levels that provide clarity and direction.

I've put together a list of items to make studying easier, going from the basics to advanced.
