Vibe coding means describing what you want and letting an AI agent write the code. Here is what that actually looks like, what it is genuinely good for, and the three ways it goes wrong.

Vibe coding is building software by describing what you want in plain language and letting an AI coding agent write, run and revise the code. You stay in charge of what gets built and whether it is any good. You just stop typing every line yourself.

That is the whole idea. The interesting part is what it changes — and what it does not.

## What actually happens

You say: "a page where I paste a link, it saves it, and it is still there after I refresh."

The agent reads your project, decides on an approach, writes the files, and — if it can run commands — starts the thing up and checks whether it works. You read what came back, run it yourself, and say what is wrong. It fixes that. You repeat until it does the job.

Four steps, in a loop: **describe, run, read, steer.** Every tool in this category has that shape, whether it lives in your terminal or inside your editor.

## What it is genuinely good at

**Getting from nothing to something.** The blank-page problem is mostly gone. A rough version of a small idea takes minutes.

**Work you understand but cannot type.** You know exactly what you want; you just do not know this language, this framework, or this API. That gap is what agents close best.

**The boring middle.** Renaming a thing everywhere. Adding the same field to six files. Writing the tests you keep meaning to write.

## The three ways it goes wrong

**It invents things.** Models produce APIs, function names and configuration options that do not exist, with exactly the same confidence as the parts they got right. The code looks plausible and fails on the first run.

**It is confidently wrong about your intent.** You ask for a search box; you also get the list silently re-sorted. Both changes look reasonable in isolation. Only one of them is what you asked for.

**It hides what you did not ask about.** Cost, security, what happens with 10,000 rows instead of 10. An agent optimizes for the request in front of it, not for the thing you forgot to say.

None of these are reasons not to vibe code. They are reasons to read what it wrote.

## The skill that matters

The bottleneck was never typing speed. It is knowing what to ask for, noticing when the answer is wrong, and being able to tell "works" from "looks like it works."

That skill is learnable, and it does not require years of programming first. It requires reading the output, running the thing, and being suspicious in the right places.
