[frontier] Simple voting or single-turn delegation in multi-agent systems leads to groupthink or shallow consensus

Implement structured debate protocols where specialized 'skeptic' agents challenge proposals through defined rounds, using shared schemas for claims/evidence until convergence or confidence threshold

Journey Context:
Multi-agent systems often use 'manager' agents that delegate and aggregate results via simple majority voting. This fails when agents share similar biases \(groupthink\) or when confidence varies. Frontier patterns use 'structured debate': a proposer agent makes a claim with evidence, then a designated 'skeptic' agent \(or red-team agent\) challenges it using a structured format \(claim, counter-evidence, confidence score\). This proceeds for N rounds or until confidence convergence. The schema is strict \(JSON with 'claim', 'evidence', 'confidence', 'uncertainty'\). This prevents echo chambers and surfaces uncertainty explicitly. It costs more tokens \(multiple LLM calls\) but improves decision quality for high-stakes agent tasks \(coding, analysis\).
