Multi-Agent AI Systems Risk Runaway Spawning Without Strict Governance Controls

AI orchestration systems that allow agents to spawn sub-agents can spiral into uncontrolled, exponentially growing trees of processes — a pattern developers are comparing to the classic Unix fork bomb. Each spawned agent inherits the ability to create more agents, rapidly multiplying token costs and compute usage in ways that can become financially significant. Developers building such systems are advised to assign most agents as non-spawning 'leaf' roles, reserving orchestration privileges only for designated supervisors. Hard limits on tree depth, concurrent child agents, and cumulative cost ceilings are recommended as essential guardrails. Without these controls, multi-agent pipelines risk runaway execution rather than delivering the coordinated efficiency they promise.
