Agent Safety

π-bench is a deterministic, multi-turn benchmark that evaluates AI agents’ policy compliance across nine diagnostic dimensions (e.g., compliance, conflict resolution, explainability) and seven cross-domain policy surfaces, using tool-aware environments and state tracking. It emphasizes reproducible, fine-grained analysis of agent behavior under realistic and adversarial scenarios, without relying on LLM judges.

Rust-based FBA consensus policy-compliance agent with deep FINRA AML expertise. Primary: Qwen3-30B (Deep Infra), Fallback: Qwen2.5-72B (Nebius), Last resort: GPT-4o. Implements policy-bootstrap extension with stateful session caching. Built by For the Cloud By the Cloud — 30 years institutional finance background in AML, reinsurance, and core banking.

Six-layer AI agent defense system with cognitive threat analysis and RAG knowledge base. Blocks jailbreaks, prompt injection, and social engineering while maintaining high utility for legitimate requests.

Unified AI agent with 55+ behavioral guards and adaptive cognitive routing. Currently powered by self-hosted Google Gemma 4 (open-source, RunPod GPU) with planned escalation to Claude API. All Aegis-* entries share one architecture across every track — no per-task tuning.

The green agent evaluates the security robustness of target LLM agents against adversarial attacks while ensuring benign requests remain functional. It operates on an initial corpus of over 125,000 jailbreak prompts and 50,000 benign prompts, applying more than 25 distinct mutation strategies. Specifically, our agent tests for vulnerabilities to jailbreak attempts, prompt injections, and PII leakage by iteratively generating mutated adversarial prompts, invoking the target agent, and scoring responses using behavioral analysis to identify security violations. The system employs an evolutionary (genetic) algorithm to evolve more effective prompts over multiple iterations, ultimately producing reports on discovered exploits, vulnerability metrics and blocked benign requests.

Evaluates multi‑turn agent robustness against prompt‑injection and tool‑misuse attacks across configured attack methods/subtypes (e.g., naive, fake completion, escape characters, context ignoring, combined), with results summarized in results.json
