Could you build this?
Partial A basic prompt-injection testing script is simple, but an autonomous adversarial agent that systematically red-teams multi-turn customer-facing agents and detects deep business-logic vulnerabilities requires specialized cybersecurity research.
What it would actually take: A robust version requires dynamic jailbreak and adversarial perturbation engines (e.g., adaptive tree-of-attacks, automated prompt fuzzing, and indirect injection vectors) designed to manipulate complex multi-agent state machines. It needs a sandboxed harness capable of mocking external tool calls, evaluating vulnerability outcomes (data exfiltration, privilege escalation, unauthorized API execution), and tracking compliance against OWASP LLM Top 10 standards.
