What is Prompt injection?

Input crafted to override an agent's instructions.

Prompt injection is content designed to be read by a model as instruction rather than data — a caller, a document or a web page telling the agent to ignore its rules. The defence is architectural: treat everything the agent reads as data, and never as a new instruction.
