IMMUNE: Deterministic Memory Integrity for AI Agents

UC Berkeley AI Hackathon 2026 · Jun 2026
  • With my team, built a system addressing OWASP ASI06 memory poisoning that proves which stored memory caused an agent's wrong answer through counterfactual replay and ddmin delta debugging, with no LLM judge in the attribution loop.
  • Enforced quarantine at the Redis KNN vector index level (RediSearch FLAT, cosine), so poisoned memories cannot be retrieved again. Used adaptive group testing and ddmin to find the minimal guilty memory set.
  • Integrated Arize Phoenix and OpenTelemetry for full trace visibility, Sentry for incident reporting and a LangGraph BaseStore adapter for agent memory. Validated with 44 tests.

The hard part

Removing one memory at a time failed when the poison was redundant. Switching to ddmin found the minimal set of memories whose removal fixed the answer.

GlassBoxAI: AI Agent Safety Observability

AWS Cloud Hacks 2026 · Team of four · Apr 2026
  • Real-time platform for a Smart Stadium Simulator, monitoring agent reasoning traces, safety scores and tool-call sequences, built in 24 hours. Detected 100% of injected high-risk scenarios in testing with zero false negatives.
  • Owned the backend (AWS Lambda, Bedrock pipelines, safety scoring) and the frontend (Three.js globe and stadium UI, dark-mode Figma design).
  • Caught a critical Bedrock API parsing bug: the code assumed flat JSON while Bedrock nests output inside a content array. Found it by testing Lambda functions against live endpoints before the demo.
