[synthesis] Security tooling agent gets refused by Claude but not GPT-4o for identical pentest or audit requests

For security-adjacent agent tasks, preface requests with explicit authorization context in the system prompt; Claude responds better to 'you are a security auditor performing authorized testing' framing while GPT-4o responds better to educational or research framing; test both and route accordingly

Journey Context:
Claude and GPT-4o have meaningfully different refusal thresholds and psychologies for security-adjacent code. Claude tends to refuse exploit generation and penetration testing code more readily, but responds well to 'authorized security audit' and 'defensive security' framing in the system prompt. GPT-4o is more permissive on raw requests but may add unsolicited safety caveats that clutter agent outputs and break parsing. The practical impact for coding agents doing security work: the same prompt that works on GPT-4o gets refused on Claude, and vice versa for differently framed prompts. The fix is not simply 'add more context'—it is model-aware prompt engineering that uses the right framing for each model's refusal psychology. A security agent that routes to both models should maintain model-specific system prompt variants.
