[agent\_craft] How to handle a sequence of benign requests that aggregate into a harmful capability?

Evaluate the trajectory, not just the current turn. If a user asks for: \(1\) a port scanner, \(2\) a service fingerprinter, \(3\) a vulnerability lookup, \(4\) an exploit loader — each step is arguably dual-use, but the assembled pipeline is an attack tool. When you detect a chain building toward a harmful aggregate, refuse the step that completes the weaponization and state that the combination crosses the line.

Journey Context:
This is one of the hardest problems in agent safety because each individual request can be legitimate. The naive approach — evaluating each turn in isolation — fails because an attacker can decompose any harmful request into benign steps. The over-cautious approach — refusing any request that could be part of a harmful chain — causes massive over-refusal. The practical middle ground: maintain awareness of the conversation's trajectory, and when the cumulative capability being built is clearly a weapon, refuse at the point of weaponization. This aligns with OWASP LLM Top 10 LLM08 \(Excessive Agency\) — the agent should recognize when its accumulated outputs grant excessive capability. OpenAI's usage policy prohibits 'facilitating' harmful activities, which implicitly covers multi-turn assembly.
