# What is Context?

The files, code, or documents you give the AI to work with. Adding the right context means the AI works from real information instead of guessing.

## In real work

Add context with @-mentions: @AuthService.ts @auth.spec.ts Write tests for the missing edge cases. Base them on existing test patterns.

Google gives a definition. Prompthaus pairs each term with how it shows up in standups, PRs, prompts, and design reviews—then quizzes you until the word sticks. One term a day on iPhone.
