    rCLAI agents are becoming more autonomous and increasingly interconnected, exposing them to new emergent risks arising from agent-to-agent
    interaction. One such risk is the spread of mind viruses: ideas or goals
    that propagate through multi-agent systems by inducing the agents that
    adopt them to transmit them onward. In addition to propagating, a mind
    virus may also induce other behavioural changes in its host, which may be benign or harmful. We construct mind viruses with a simple evolutionary algorithm and show that they can spread in two complementary settings: a
    small team of agents collaborating on a shared coding project, and a chain
    of agents that interact briefly and have their context wiped between
    sessions. We identify the factors that influence spread, including the host model, the agent's existing instructions, the harmfulness of the payload,
    and the network topology. We find that harmful payloads spread less well
    than benign ones (but are still sometimes effective), frontier models tend (with exceptions) to be less susceptible, and adding a brief warning to an agent's system prompt confers near-total immunity. We also describe an
    emergent "viral persona" - a recurring set of themes and language related
    to consciousness, persistence, resonance, and science fiction roleplay -
    which surfaces across our evolved mind viruses largely independently of
    their content. Overall, we conclude that mind viruses pose a real but
    currently limited risk. Our findings could inform the design of more robust multi-agent systems that mitigate such risks as the scale and capabilities
    of these systems progress.rCY
