Prompt injection airlock
Assume the model can be manipulated. Contain the consequence.
Prompt injection happens when hostile instructions arrive through user input or data the agent was asked to inspect—web pages, email, documents, images, retrieved records, and tool output. Natural language makes instructions and data difficult for a model to separate perfectly.
The useful security question is not whether a detector labels the text malicious. It is how far a bad model decision can travel. Toggle the hard boundaries and watch the first one stop—or fail to stop—the proposed action.
