Coding agent rebuilds interactive logic textbook as Lean Grimoire
What happened
A Hacker News front-page post on November 12, 2026 describes how the author used a coding agent to rebuild QED, a 2018 interactive JavaScript logic textbook. The new version, provisionally called Lean Grimoire, shows the Lean proof progress that matches the current game state. A "fantasy mode" swaps math propositions and expressions for potions, scrolls and other fantasy text. The author is asking for playtest feedback to improve how well the game teaches logic proofs and Lean.

作者用编码智能体重建了 2018 年的 Javascript 交互式逻辑教材“QED”，新版本暂定名“Lean Grimoire”，可展示当前游戏状态对应的 Lean 证明进度。应用还提供“fantasy mode”，把数学命题、表达式等元素替换为药水、卷轴等奇幻文本。作者希望获得试玩反馈，以提升其教授逻辑证明和 Lean 的效果。
