Vibe coding
Vibe coding is building software by describing what you want to an AI and accepting the code it writes without reading it, judging only by whether the result seems to work.
Select any words here to ask your Maestro about them.
The app you vibe coded says March sales were $58.0k; the register says $52.0k. March had $3.0k in refunds. Both read the same file. What did the app do?
Where it comes from: Andrej Karpathy named it in February 2025: you tell the AI what you want, accept every change and, when something breaks, paste the error back for it to fix, without reading the code.
What it's good for: trying an idea in minutes: a weekend app, a prototype, a tool just for you. An AI agent like Claude Code does the work from your prompt.
Where it breaks: with data, a bug doesn't crash: it gives a number that looks fine. So before you sign off on a number from code you didn't read, ask for a unit test with an answer you already know.
Practice it in Ask for the test up front, where you ask for the code along with the test that checks it.
How it's used
A vibe coding session
sales-app/
- $ claude
- > Make me an app that reads transactions.csv and charts sales by month.You describe what you want, in plain English, not how.
- ● Write(app.py)The agent writes all the code.
- ● Bash(python app.py)It runs it and opens the chart.
- marked: Done: the app charts sales from January to June.If it looks right, you accept it. That's vibe coding: you judge the result, not the code.
When to look closer
It runs with no errors
Before you use the number
- marked: python app.py → runs, no errors
The app runs with no errors and the chart looks fine. How would you know it adds up what it should?
Ask your Maestro about Vibe coding
It answers from the free course page closest to this word, the way it answers while you study.
You: What does "Vibe coding" mean, in plain words?
Your Maestro: I'll explain it with a case of yours: it sticks better than a definition. What tool just for you would you vibe code?
Asking about: Answers from the page "What should I check in a table before cleaning it? Build a problem inventory"
