Effective AI Prompting Guide

Learn how to craft effective prompts to get the most out of AI-generated code and solutions

Why Be Specific When Requesting Code with AI?

Most people believe that Artificial Intelligence will give them exactly what they want, as if it could read their mind. But AI doesn't "understand" like a human, nor does it "know" what you want. What it does is more technical, but also more powerful if you know how to use it well.

The truth: AI is a statistical model, not a mind reader.

Models like ChatGPT work by predicting the most likely response based on the text you give them. That means if your prompt is too generic, the model will try to give you a common or superficial answer that has statistically worked before for similar prompts.

The key: the prompt is the exam, and you decide how easy or difficult it is to pass.

When you create a prompt, you're launching a "challenge" that the model must solve. The more specific your challenge, the narrower the path it has to follow.

A generic prompt has an easy validator to beat: any half-decent response will seem valid.

A precise prompt has a demanding validator: the AI has to work harder to get it right, and fine-tune its response much more.


Comparative Example

Generic prompt:

"Make me a login in React."

Likely result:

A basic component, with few details, no validation, no careful design, no real security.

Specific prompt:

"Create a React login form with Tailwind, email and password validation, responsive design, decoupled structure, error handling, and production-ready code."

Likely result:

A well-structured component, more useful and directly applicable in a real project.


The more specific you are, the more you reduce ambiguity. And there lies the power: when you reduce ambiguity, AI behaves like a serious technical collaborator. It returns more professional, more useful code that's better aligned with what you really need.

Quick Guide for Effective Code Prompts

1.Define the CODE OBJECTIVE

Ask yourself or indicate:

  • What do I want this code to do?
  • What is its ultimate purpose?

Example prompt:

"I want a functional contact form that sends messages to an email using Node.js."

2.Specify the CONTEXT or ENVIRONMENT

This includes the language, framework, type of application, operating system, etc.

Useful terms: React, Next.js, Vue, Node.js, Python, Flask, mobile app, backend, microservice, REST API, etc.

Example:

"In a web application with React and Tailwind, I want a component..."

3.Declare the FUNCTIONAL REQUIREMENTS

Detail exactly what it should do.

Useful keywords:

  • form validation
  • user authentication
  • database connection
  • file upload
  • pagination
  • real-time search

Example:

"It must validate that the email is valid and display error messages if it's not."

4.Add QUALITY or ARCHITECTURE REQUIREMENTS

Guide the AI with terms that improve code quality.

Use terms like:

  • decoupled
  • modular
  • scalable
  • maintainable
  • reusable
  • clean
  • readable
  • production-optimized
  • robust
  • following SOLID principles

Example:

"The function should be decoupled from the frontend, robust against errors, and written with SOLID principles."

5.Include DESIGN DETAILS (if applicable)

Ideal for UI/UX-related prompts.

Useful terms:

  • clean design
  • eye-catching design
  • responsive
  • user-friendly
  • experience-centered
  • accessible
  • with good UX-UI practices

Example:

"The design should be responsive and user-friendly, with clearly differentiated fields and accessible colors."

6.Add EXTRA CONDITIONS (optional)

If you need:

  • No external dependencies
  • TypeScript compatible
  • Includes unit tests
  • Production-ready
  • Commented
  • With code explanation

Example:

"I want the code to be in TypeScript, with unit tests and explanatory comments."

7.Use EXAMPLES or TEST DATA (if applicable)

Help the generated code have realistic cases.

Example:

"Simulate 3 users with name, email, and role, and display their data in a responsive table."

General template for effective prompts:

"Create [component or function type] in [technology], that [explains what it does], with [design type] design and [quality adjectives] code. Make sure that [extra conditions]."

Complete example:

"Create a table component in React with Tailwind that displays a list of products. It should be responsive, reusable, and readable. The table should allow sorting by name or price. Use simulated test data. The design should be clean and mobile-friendly. Don't use external libraries."
