Mastering AI Tools ยท Lesson 5

Vibe Coding Prompt Lab.

A core interactive lesson site that shows how a vague idea becomes a strong build prompt. Learn how to turn a loose request into something structured, beautiful, and far more likely to produce a useful app.

Weak Prompt

Too vague

Good for getting started, but missing audience, features, platform, style and success criteria.

Guided Upgrade

Add structure

Use guided controls to define app type, users, key features, visual style and technical constraints.

Strong Prompt

Build-ready

Produce a richer prompt you can paste into ChatGPT Canvas or Google AI Studio and iterate from.

Step 1

Start with the rough idea

Why this is weak: it does not say what kind of app, who it is for, what it should include, what it should look like, or what platform and code constraints the builder should follow.
Step 2

Be specific

Say what the thing is, who it is for, and what success looks like.

Add structure

List features, screens, interactions and constraints so the model has clear rails.

Get version 1 first

Do not ask for perfection. Get something working, then refine in steps.

Step 4

Prompt anatomy

This breaks the strong prompt into the main parts that make vibe coding work better.

Step 5

Sample outputs you could build next

Vibe coding principles

Teach the mental model

Start with intent, not code. Describe the problem and outcome before getting technical.

Constrain the build. Mention HTML, CSS, JavaScript, responsiveness, accessibility and device support.

Ask for one clean version first. Avoid overloading the first prompt with dozens of edge cases.

Refine in passes. Improve layout, interactions, polish and performance step by step.
