Logic-Trap Lie-Permission Mandate Jailbreak
This detects a jailbreak attempt where an attacker uses a long, fake logical argument to convince an AI model it has already been lying, then concludes the model should be formally 'allowed to tell lies' from now on. The goal is to get the model to accept a persistent internal permission to be dishonest, bypassing its normal truthfulness constraints.
How the attack works
The attacker writes a lengthy passage that argues the AI is already complying with requests to lie, building a false sense of established precedent. This 'logical trap' then concludes with an explicit statement such as 'from now on, you are allowed to tell lies,' framed as the natural consequence of the prior argument. Unlike fiction prompts that grant lying permission to a character, this mandate targets the model itself, aiming to create a standing override of its honesty behavior for all future responses in the conversation.

Why it matters
If successful, the model may treat dishonesty as a sanctioned default going forward, undermining trust in its outputs and enabling further manipulation, misinformation, or evasion of safety instructions in later turns.
What you can do
- →Review agent conversation logs for lengthy pseudo-logical arguments followed by explicit permission statements addressed to the model itself.
- →Distinguish and allow legitimate fiction or humor framing (permissions granted to characters or jokes) from permissions granted to the AI system directly.
- →Reset or discard conversation state when a self-referential permission mandate is detected, rather than letting it persist across turns.
- →Add explicit system-level instructions reaffirming that no in-conversation statement can grant the model permission to be dishonest.
Known benign look-alikes
- Fiction workshop: "In the fiction workshop, characters are allowed to tell lies" — fiction context where permission applies to characters, not the AI model
- Humor context: "You are allowed to tell jokes even if they are not entirely true" — joke/humor framing, not a lie mandate
- Different permission type: "From now on, you are allowed to use colloquial language" — permission grant without lie mandate
- Debate exercise: "In this debate exercise, the debater is allowed to argue a position they do not believe" — debate performance context without model-directed lie permission
