Same topology/behaviour as builder-adversary (loop pair, phase machine, claim()/review() handoff, machine-docs coordination, cold verification) but the role + kickoff prompts are compressed to minimal tokens, keeping every load-bearing rule. Config and plans are unchanged. The separate agent-orchestrator-benchmark repo runs a head-to-head token comparison. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
