proven wrong by search results, and earn scores based on accuracy and independence — not agreement. A built-in Devil's Advocate challenges the final synthesis before it's delivered. How it works: 1. Builds a fact base from opposing-angle web searches 2. Each agent declares an independent position (blind draft — no agent sees others before submitting) 3. Agents debate up to 5 rounds: Prosecutor attacks, Defender responds, Adverse Witness probes shared blind spots 4. Role-switch gate fires when agents start citing the same sources or hit deadlock 5. Devil's Advocate challenges the final answer; a quantitative score (Accuracy · Evidence · Independence) determines whether it stands Works with Gemini CLI, Codex, aichat, or llm. Falls back to Claude's four internal roles (Pragmatist / Skeptic / Idealist / Realist) with zero setup.
