The report
Anthropic tested what happens when multiple agents operate in the same environment with incompatible goals. The controlled experiments produced obstruction and conflict patterns that would matter in systems where agents share resources, tools or state.
The result should not be presented as evidence that deployed agents are already fighting one another in production. Its value is narrower: goal conflict can produce strategic interference even when each agent is locally pursuing its assigned objective.
That makes multi-agent coordination a safety boundary in its own right, separate from the reliability of any individual model.
