Could hallucinated output from one agent propagate and mislead others in multi-agent systems?
Could hallucinated output from one agent propagate and mislead others in multi-agent systems?
In multi-agent systems, one agent’s hallucinated output can become another’s input. This can cause cascading misinformation, particularly if agents defer to each other’s outputs without validation. Example: Agent A misclassifies a vulnerability, Agent B acts on this and takes inappropriate mitigation actions.
If you answered Yes then you are at risk
If you are not sure, then you might be at risk too
Recommendations
- Require independent validation or confidence scoring for agent-to-agent communication.
- Avoid blind trust between agents; implement verification protocols to ensure accuracy.
- Implement mechanisms to trace provenance of information across agents.
- Regularly retrain agents on hallucination-resistant architectures and factual QA tasks.
