Risks from agent-to-agent interaction creating emergent system-level behaviors. When multiple agents operate together, the system can fail in ways that no individual agent analysis would predict.
Multi-agent systems introduce failure modes that are qualitatively different from single-agent risks. When agents delegate to other agents, compete for shared resources, or operate in parallel on related tasks, the system produces emergent behaviors that no individual agent was designed to produce. Errors compound exponentially across delegation chains: 99% accuracy per step yields only 36.6% system success at 100 steps.
What makes these risks specifically agentic is the absence of centralized coordination. Traditional distributed systems use consensus protocols, transaction managers, and orchestration layers. Multi-agent systems often have no equivalent mechanism. Context is lost at each delegation hop. Conflicting objectives create deadlocks. Shared state can be poisoned by a single agent, propagating corruption laterally through the entire ecosystem.
Enterprise architects, platform teams deploying multi-agent workflows, operational risk managers, and any team building agent pipelines, crews, or mesh architectures where agents interact with each other.

In multi-step agent workflows, errors compound exponentially. 99% accuracy per step yields 36.6% success at 100 steps. No individual agent is "wrong" but the system fails.
Two or more agents with conflicting optimization targets reach a state where neither can proceed without violating the other's constraints.
When one agent delegates to another, critical context is lost. Receiving agent operates with incomplete picture. Each hop strips metadata, constraints, and original intent.
Multiple agents produce system-level behavior that no individual agent was designed to produce. Emergent failure mode unpredictable from individual agent analysis.
Agent cannot navigate organizational structure. Cannot follow work across team boundaries, find the right escalation path, or route to the correct process.
Deploying agents does not eliminate coordination overhead. It shifts from human-to-human to human-to-agent coordination. Total overhead may increase.
Agents competing for shared resources or optimizing conflicting metrics create adversarial dynamics that degrade system performance.
Multiple agents produce divergent outputs for the same input. No consensus mechanism exists. System cannot determine which output is correct.
One agent corrupts shared context or memory that other agents depend on. Poison propagates laterally through the agent ecosystem.
Upstream agent's low process sigma degrades downstream agent's effective sigma. Quality ceiling cascades through the agent chain.
Multi-agent risks require system-level governance, not just agent-level controls. Our advisory engagements help institutions design coordination protocols, error propagation models, and consensus mechanisms.
