Antibody

Antibody Every AI-written code change must survive an attack by a second AI — with proof — before it is allowed to reach production. Antibody is a GitLab Duo pipeline for the "Life After Code" Transcend Hackathon. It treats a codebase like an immune system: when one AI fixes a vulnerability, a...

GRAD: Graph-Structured Antibody Defense for LLM Agents

Memory poisoning and decomposition attacks distribute malicious evidence across the operations of large language model agents. Existing request-level defenses can miss such attacks because they assess individual inputs without connecting earlier information to later actions. Moreover, detectors...

AgentAntibody: An Adaptive Immune System for Defending LLM Agents against Prompt Injection

Prompt injection remains a critical threat to LLM agents, yet existing defenses treat each task as a self-contained problem, independent of previous encounters. In practice, user requests are often underspecified: they describe the desired outcome without fully specifying acceptable behavior. An...
