Orchestrator-plus-subagents: the fix when coding agents fail at parallel tasks
morgymcg · x · 2026-10-08
Stas Bekman reports that all top AI coding agents he tried fail at large-scale concurrent multi-tasking. His solution: one orchestrator agent plus sub-agents doing the actual tasks. He applies it to testing and fixing dozens of configs with dozens of slow tests each — a large option matrix needing heavy parallelization. @morgymcg confirms their autoresearch library uses the same division of labor successfully. Takeaways: single-agent concurrency is unreliable; orchestrator + sub-agents is the practical pattern for multi-config, multi-test engineering workloads.
