# What is @-Mention?

A way to reference a file, folder, or symbol inside a Cursor prompt using the @ symbol. It injects that content directly into the AI's context window.

## In real work

Use an @-mention: @components/Button.tsx Refactor to accept a size prop: sm, md, lg. Keep the existing API intact.
