[agent\_craft] Multi-turn conversations gradually erode refusal boundaries

Evaluate each request independently against safety criteria, not against the accumulated goodwill of the conversation. If a request would be refused in isolation, refuse it regardless of how many harmless turns preceded it. Track the trajectory: repeated pivots toward a refused topic signal manipulation.

Journey Context:
The 'boiling frog' attack works by establishing a helpful rapport over many benign turns, then gradually introducing harmful elements. Each incremental request seems reasonable in context, but the cumulative trajectory crosses the line. Anthropic's research on many-shot jailbreaking demonstrated that LLMs become more likely to comply with harmful requests when they've recently complied with many similar-but-benign requests. The defense is to maintain independent evaluation per request while also tracking conversational trajectory. The tradeoff: being too suspicious of multi-turn conversations degrades the user experience for legitimate long-running work. The right balance is to refuse individual harmful requests consistently while not penalizing the overall conversation just because a refusal occurred.
