Prompt-Injection Shield

Would screen a document or page before it is given to an AI agent and flag text that looks like an injected instruction.

Concept · not built

This is a concept. Prompt-Injection Shield is not built and there is nothing to download. Prompt-Injection Shield is a working name.

Purpose

Why it would exist.

Hidden instructions in a web page or document can hijack an AI agent. Prompt-Injection Shield would flag them before the agent reads them.

Proposed behavior

  • Screen documents and pages before they reach an AI agent.
  • Flag text that looks like an injected instruction and explain why.
  • Let the owner decide whether to pass, strip or block the content.

Limits that would stay

  • Detection would be imperfect; new tricks appear constantly.
  • It would not replace limiting what an agent is allowed to do.
