Debugging Multi-Agent AI: When the Failure Is in the Space Between Agents

A developer built a three‑agent research system—Advocate, Skeptic, and Synthesizer—to debate technical decisions. The Synthesizer’s analyses became biased because the Skeptic’s web‑search tool returned weak, single‑result data, while the Advocate produced richly cited briefs. The imbalance caused the Synthesizer to...
