"Students often ask AI tools questions their own professors never answered — and get confident, wrong answers back. Closed Chair takes a different approach: it's an agent config built to operate strictly within a loaded packet schema, refusing to fetch outside information or fabricate policies like late-work rules.\n\nWhat makes it useful for exam prep is its restraint. It won't finish a problem for you — instead it applies syllabus-verb prompts (explain, derive, justify) to mirror how your course actually tests you. If the packet doesn't cover something, it says so and defers to the human professor rather than filling the gap with a guess.\n\nFor $36, you get the agent config, the packet schema, and eval clips showing the behavior in action — built for students and researchers who want exam prep grounded in their actual syllabus, not the open internet.\n\nSee the full spec: https://multinicheai.com/product/AI-AG-111"
