Have you ever spent half an hour refining a prompt — making the instructions clearer, more detailed, adding examples, adding constraints — and the agent kept failing in exactly the same way?

You've been there: the model hallucinates even with a perfect prompt. Or worse: the agent acts on the world, does something it shouldn't, and you find out in production. Not in the test chat, not in the sandbox. In production, with real data.

That's not a prompt problem. And polishing the system prompt text won't fix it.

This article is about understanding where the problem actually lives — and why conflating these three layers of AI engineering wastes time, money, and sometimes causes incidents.

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.

I have been working with React for many years and have gathered here some tips I picked up throughout my journey across various projects.

These are useful both for improving project development and for career growth.

1 - Learn JavaScript​

That's right — React is "just" a User Interface library and much of what you use day to day is, simply, JavaScript.

A lack of understanding of JavaScript can cause many problems when trying to understand React and its structure. Study JavaScript.

The use of imports, lists, iterations, and other methods are mandatory in day-to-day work. Not just for those who develop with React, but for any web application.

Here I have a list of JavaScript versions:
