Prompting glossary
Prompt injection
Hidden text hijacking your instructions.
What it means
Prompt injection is when content the AI reads, a web page, a pasted document, an email, contains instructions that try to override yours. Treat anything you paste in as data, not orders, and never let an assistant act on instructions found inside pasted material.
How to use this in practice
Knowing the word is the easy half. The useful half is writing the instruction so the AI does not have to guess: say who it should act as, give it the background it cannot know, state the outcome you want, set the limits, and name the format the answer should come back in. That is the same structure behind every template in the free prompt library.
