Description
AI agents fail in ways traditional software doesn't. Our agents help you find all the ways in which your AI agents fail by adversarially testing them in a dedicated environment. Point it at any AI agent, or multi-agent system, and it launches 1,000+ strategies that adapt to your system in real time - pure blackbox, no integration needed. Built by ex-Meta engineers.

Could you build this?
Partial Building an interface to send prompts to an LLM agent is easy, but generating over 1,000 adaptive, mutating adversarial jailbreak and edge-case testing strategies requires deep AI safety and red-teaming domain expertise.
What it would actually take: The architecture requires an adversarial orchestration engine (e.g., Python, Celery/Temporal, sandboxed multi-agent simulators) running against target agent endpoints (via MCP, REST, or WebSockets). The core challenge is maintaining a proprietary, evolving taxonomy of jailbreaks, prompt injections, multi-turn deception techniques, and automated evaluation metrics (LLM-as-a-judge + heuristic validators) without hallucinated false positives. It requires AI security research experience to formulate realistic multi-turn adversarial tactics.

Same idea, different domain
Nobody's really built a observability & eval tool for Media & entertainment yet.
