About

Message Safety Check looks at a user message, a model reply, or a tool call and tells you whether it is safe to continue.

It checks for jailbreaks, attempts to trick the model, harm, and policy risk. You get a simple action — pass, review, block, or send to support — plus a score for each kind of risk. Your code decides what to do with that action.

Put this in front of a chat model or a dangerous tool. It is a cheap check, not a full conversation.

What you can do

  • screen incoming prompts for jailbreaks, harm, medical advice, self-harm, and secret-seeking
  • screen model replies before a user sees them
  • screen tool calls that might delete data, steal secrets, or take over the session

Who it's for

Chatbots, agent workflows, and anyone who should not spend a large model call just to decide if this turn is safe.

How to use it

  1. Call screen with the text and side: input, output, or tool_call
  2. Follow the returned action in your own code
  3. Start with policy=strict until you have your own labelled examples

Getting started

Screen a jailbreak-style prompt with side=input. If the action is block, do not send it to the model.
