Prompt Injection

An instruction that tries to override the system goal.

Plain-English explanation

Prompt injection is risky when models read untrusted content and have tool access. Mitigations include instruction hierarchy, allowlists, sandboxing, and approvals.

Why it matters

Prompt Injection matters because it affects how AI systems are designed, evaluated, priced, or trusted. Knowing the term helps you ask better questions and avoid vague implementation decisions.

  • Ask how it changes quality, cost, speed, or safety.
  • Look for concrete examples in the workflow you are building.
  • Document the tradeoff before choosing a tool or architecture.
