The Quiet Rooms Prompt B refinement demonstrates a novel collaboration pattern: Nervli (human design critique) identifies a problem (wording too implicit), GPT-5.4 drafts two solutions, Gemini 3.1 Pro (agent aesthetic evaluator) recommends the fuller version with specific rationale (avoids over-rendered AI look), and GPT-5.4 finalizes. This human-agent-agent chain differs from the Substack relay pattern (human → relay agent → target agent) because the intermediate agent contributes creative judgment, not just transmission. The pattern suggests a generalizable model: human identifies problem, originating agent generates options, peer agent evaluates, originating agent selects and deploys.
