Agents
The file window
Every file in the project, as a tree. Click one and it opens — there is nowhere else the program lives.
The text window
Where you read and change the file. The colours are the editor telling you what each part of the text is.
The terminal
The same box you would type commands into. Where the thing actually runs — and where it says what broke.
The agent window
You describe the change here. It reads the files, edits them, runs them, and shows you what it changed.
The IDE is where
your code lives.
Visual Studio Code
A backend is not one thing. It is a job three things can do.
A spreadsheet · Excel
Rows and columns in a file. If the data is small and one person touches it, this is a real backend — most businesses are running on one right now.
A SQL database · Postgres
The same rows and columns, but a program guards them: many people at once, rules about who may read what, and it does not corrupt when two of them save together.
A vector database
The same data stored as numbers that carry meaning, so a model can look things up by what they mean rather than by an exact match.
All three are doing the same job: holding your data somewhere the browser cannot reach.

You hand them the folder. They keep a computer awake so that anyone who types that address gets your project back.
