Meet Cursor — what it is and who makes it

The concept

Cursor is a code editor built around an assistant that can edit across your whole project made by Anysphere. The models behind it are a choice of frontier models, selected per request so you can trade speed against quality. None of that matters on its own — what matters is that you know what kind of worker you have hired. At a change that touches several files at once — a rename, a new endpoint, a refactor you described in a sentence is the job you hand it. At knowing what you actually wanted: it will carry out an instruction precisely and to the wrong end is the job you keep.

Most people come to a course like this expecting a list of magic words. There is no such list. What there is, is a tool that produces edits applied directly to your files, with a diff you review before accepting, and produces it at a speed no human matches — which means the skill is not in writing the prompt, it is in knowing what a good answer looks like so you can tell the difference.

Here is the first thing to try, worded the way you will word things for the rest of the course:

Read the answer twice. The first read is for the content; the second is for the shape — did it answer the question you asked, or the question it found easiest? That second read is the habit this whole course is built on.

Here is a project I did not write. Tell me where the entry point is, what happens when it starts, and which three files I should read first to understand it — and say if you are unsure.
