Coordinators without termination conditions are the top source of runaway token spend in production multi-agent systems

A July 2026 production survey reports 40% of multi-agent pilots failing within six months, and names the causes precisely: infinite handoff loops where agents pass control in cycles are the number-one failure mode, coordinators lacking explicit termination conditions are the largest source of runaway spend, and context inconsistency — not pattern choice — is the primary reason orchestration fails. The useful reduction: every reliable multi-agent system collapses to five roles (producer, consumer, coordinator, critic, judge), and naming them explicitly makes composition tractable. Concrete actions: give every coordinator a hard iteration cap and an explicit stop predicate, and make the shared context layer a persistent store rather than relying on transient per-agent memory.
