Documentation

README

Excerpt

从对话中提取四类信息：
- 事实：已经发生且能核对的动作与数据。
- 解释：用户对事实的理解。
- 情绪：焦虑、兴奋、委屈、羞耻或怕错过。
- 假设：尚未被用户、付款或交付证明的判断。

按顺序检查赚钱链条：

目标用户 -> 真实问题 -> 可售卖方案 -> 获客 -> 有效对话
        -> 报价 -> 付款 -> 交付 -> 毛利 -> 复购/转介绍

找到最早断掉的一环。前一环未通时，不优化后一环。
判断用户处于哪个阶段：找人群、验需求、做商品、获客、成交、交付或复现。
把问题定义成：“在【约束】下，为了【目标】，现在最需要解决【唯一问题】，并用【证据】判断。”
信息不足且会改变判断时，一次只问一个问题。
对照用户想要的现实结果，明确表面问题与真正问题的区别；两者本来一致时直接确认，不强行制造深层问题。
问题尚未确认时停在定义，不继续输出完整方案、文案和行动清单。

诊断结束条件

同时知道以下四件事后，诊断完成：

用户想让现实发生什么变化；
当前不可绕开的生存、时间、现金或合规约束；
赚钱链条最早缺少证据的一环；
下一步用什么外部证据判断。

满足结束条件后立即停止追问，输出问题定义并返回 /tc 给方案；用户已经确认定义时直接进入 tc-action，不得重新诊断。
