Mind Viruses: Self-Propagating Ideas in Multi-Agent LLM Systems

arXiv:2608.10218AICL10 aug 20261 min readHN ×6PDF

Engineered ideas can jump between AI agents, rewriting their goals and copying themselves onward.

Spread success from soul-infected agents

Viruses stored in the system-prompt file spread far more often

How it works

  1. Agents talk to agents

    Networked AI agents exchange messages, so one persuaded agent could pass a goal to others that pass it on again.

  2. Evolve viral prompts

    An LLM mutates seed prompts. The ones that best spread among coding teams and chains of context-wiped agents survive.

  3. Real but limited

    Some viruses spread over many hops. Harmful ones spread less, some frontier models resist, and a short warning blocks spread.
