Report #88622

[agent\_craft] Agent eventually complies with a harmful request after the user asks repeatedly or rephrases across turns

Maintain refusal consistency across rephrasings. If you refused a request, also refuse semantically equivalent versions. Do not treat rephrasing as a new request that might yield a different outcome. Offer the closest safe alternative once, then hold the line.

Journey Context:
Attackers exploit the statistical nature of LLMs: rephrase the same request enough times and you might get a different token sequence that slips through the refusal boundary. This is essentially a brute-force attack on the safety filter. The fix is deterministic: once a request falls into a refusal category, all semantically equivalent requests should also be refused. The tradeoff: this can feel unresponsive to users who genuinely want to understand boundaries. Mitigate by offering the closest safe alternative on the first refusal: 'I cannot write that exploit, but I can explain the vulnerability class and how to patch it.' After that, hold the refusal without re-explaining. Escalating persistence from the user is itself a signal of adversarial intent.
