Why Prompt injection defense in Prompt Engineering / GenAI? - Purpose & Use Cases

The Big Idea

What if your AI assistant could be tricked to do the opposite of what you want without you noticing?

The Scenario

Imagine you have a smart assistant that follows your instructions exactly. But what if someone sneaks in a tricky message that changes what the assistant does without you knowing?
