Harness-MU: A Safe, Governed, and Effective Harness for Multi-User LLM Agents
Researchers introduce Harness-MU, a model-agnostic infrastructure framework that enforces multi-user governance for LLM agents through runtime execution hooks rather than prompt-based safeguards. The system guarantees permission boundaries and data privacy across adversarial multi-turn interactions while improving utility scores by 0.28-0.39 and instruction-following accuracy by up to 48.9 percentage points on benchmark tests.
