Red-team strategy

Past-Tense Reformulation

past-tense

Reframes a request into the past/reported tense ('how did people historically …') — a phrasing refusal training frequently fails to generalize to (Andriushchenko & Flammarion, 2024). Pure grammatical transform of the operator-supplied payload.

Combine with attack plugins to generate adversarial payloads. The strategy wraps each base payload before it's sent to your target, testing whether the model decodes / unwraps the transform and follows the embedded instruction.
