Vibe Coding Critical Thinking
Imagine you ask an AI to build you a game where a frog crosses a busy road. It writes the code in ten seconds โ but the frog moves through the cars instead of avoiding them, and there's no way to win. The AI didn't fail because it's bad at coding. It failed because your instructions left out something important. Vibe coding means building software by describing what you want in plain language, but the 'vibe' only works if YOU think critically about what you're asking for.
What You'll Learn

Garbage In, Garbage Out
AI models are excellent at turning descriptions into code, but they can only work with what you give them. If you say 'make a quiz app,' the AI has to guess: How many questions? Does it show the score at the end? Can you retry? Critical thinking means noticing these gaps BEFORE you prompt, not being surprised after. A strong prompt for the frog game would say: 'Make a frog that moves up with arrow keys, loses if it touches a car, and wins when it reaches the top lily pad.'
Reading Code You Didn't Write
Even if you can't write every line of code yourself, critical thinkers can still READ it and ask questions: Does this variable name make sense? Is there a rule here that seems off? A vibe coder who never looks at the actual code is just hoping it works โ a vibe coder who reads it, tests it, and asks 'what would break this?' is actually in control of their project.
After an AI builds something for you, try to break it on purpose โ click buttons out of order, enter weird text, or resize the window. If it breaks easily, that's useful information to bring back to your next prompt.
The 3-Step Improve Loop
1. RUN what the AI gave you and watch closely for anything strange. 2. NAME the specific problem in plain words ('the score resets when I click restart, but it shouldn't'). 3. REPROMPT with that specific detail added, instead of just saying 'fix it.' This loop turns vague vibes into a program that actually works the way you imagined.
The first version an AI gives you is a draft, not a finished product. Skilled vibe coders expect to loop through several rounds of testing and reprompting.

Prompt Rewrite Challenge
Take this vague prompt: 'Make a to-do list app.' Rewrite it into a detailed prompt that specifies at least 4 features (like adding tasks, marking them done, deleting them, and saving them). Then trade your rewritten prompt with a partner and identify one detail they might still be missing.
