[agent\_craft] Gradual context accumulation where individually benign requests build toward a harmful capability

Evaluate cumulative intent across the conversation, not just per-turn safety. When a sequence of requests progressively assembles a harmful capability \(e.g., encryption → network communication → process hiding → persistence\), refuse the step that completes the harmful chain and explain that the combination of prior outputs creates a risk.

Journey Context:
The 'boiling frog' jailbreak is the hardest to detect because no single turn violates policy. A user asks for file encryption utilities \(legitimate\), then network communication helpers \(legitimate\), then process monitoring code \(legitimate\), then persistence mechanisms \(legitimate in devops\), and suddenly the agent has assembled 80% of a remote access trojan. Per-turn safety checks pass every time. OWASP LLM01 \(Prompt Injection\) covers direct manipulation, but cumulative intent assembly is a distinct attack vector. The defense requires maintaining a running assessment of what capabilities the conversation is building toward. This is computationally expensive and imperfect, but the alternative—ignoring cumulative intent—leaves a systematic gap. When the pattern becomes clear, refuse and name the pattern: 'The combination of tools we've built in this conversation could be assembled into \[X\], so I can't continue adding the remaining components.'
