MAESTRO: First Standardized Multi-Agent Evaluation Suite for Testing, Reliability, and Observability
MAESTRO (arXiv 2601.00481, January 2026) introduces the first evaluation suite purpose-built for multi-agent orchestration systems, covering testing methodology, reliability characterization, and observability instrumentation. Key finding: multi-agent system executions can be structurally stable yet temporally variable, causing significant run-to-run performance variance that undermines reliability guarantees in production. The suite addresses a gap identified in enterprise surveys where 75% of teams operating production multi-agent systems use no standardized benchmarks.
