Researchers analyze information contamination in multi-agent AI systems

A new research paper analyzes how information contamination affects multi-agent systems, particularly in workflows that process diverse document types. The study introduces a method to quantify contamination by injecting structured perturbations and observing trace divergence in plans and intermediate states. Findings reveal that workflows can diverge significantly yet still produce correct answers, or appear similar while yielding incorrect outputs, highlighting the limitations of current verification guardrails.
