Patrick C Toulme(@PatrickToulme):I do not think alot of people appreciate how difficult it is to make a quality harness, specifically an extremely parallel one that can scale out. Making a harness that can run say a lead agent and spawn individual subagents is pretty trivial. A harness that can stablely run nested agents and not crash for days is extremely hard.
