Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

stop-doing-list scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Stop Doing List — 不为清单构建法

R — 原文 (Reading)

"好的公司都一定是有一个长长的'Stop doing list',就是'不做的事情'。秘诀不是做了什么而是不做什么。"

— 段永平, 第7节

"发现是错的事情的时候要马上停止,不管多大的代价都是最小的代价。"

— 段永平, 第3节


I — 方法论骨架 (Interpretation)

Stop Doing List 是一套通过"不做什么"来定义"做什么"的逆向战略框架。它不是消极的回避,而是主动的战略排除。

核心逻辑:

  1. 两类不做:普世禁忌(谁都不该做的,如欺骗)+ 使命绑定(与公司愿景冲突的,如破坏品牌的事)
  2. 纠错机制:发现错了立刻停,此时代价永远最小——沉没成本不是继续的理由
  3. 累积效应:坚持10-20年,与不做清单的对手差距会巨大
  4. 建构方法:每条不做的背后都有故事、道理和逻辑,不是拍脑袋列的

段永平体系的具体条目(作为参考模板):不讨价还价、不做代工、不借钱、不赊账、不拖付货款、不晚发工资、不做不诚信的事、不攻击竞争对手、不打价格战、不追求性价比、不做没差异化的产品、不弯道超车、不盲目扩张、不赚快钱、不虚夸产品。


A1 — 书中的应用 (Past Application)

案例 1: 步步高拒绝OEM订单

  • 问题: 沃尔玛下100万台VCD的OEM订单,利润丰厚
  • 方法论的使用: 段永平问"10年20年后回头看,做OEM对我们建立品牌有帮助吗?"答案是没有——资源会被分散
  • 结论: 拒绝订单,全力做自有品牌
  • 结果: 后续OPPO/vivo成为全球前五手机品牌,而同期做OEM的公司大多消失

案例 2: OPPO退出豆浆机市场

  • 问题: OPPO做过豆浆机,发现方向不对
  • 方法论的使用: 发现错了→立刻停,几亿损失在所不惜
  • 结论: 退出豆浆机,聚焦手机
  • 结果: 聚焦后OPPO成为全球前列手机品牌

案例 3: 统一价格、不设销售部

  • 问题: 行业惯例是大客户谈折扣、小客户全价
  • 方法论的使用: 把"不讨价还价"列入Stop Doing List
  • 结论: 所有客户一个价,省掉整个销售部门和议价成本
  • 结果: OPPO/vivo年收入合计400亿美金,没有Sales部门

A2 — 触发场景 (Future Trigger) ★

用户会在什么情境下需要这个 skill?

  1. 用户在制定公司战略或个人计划,列出了一堆想做的事但缺乏筛选标准
  2. 用户的公司发展太快,担心失控或犯致命错误
  3. 用户面临一个"看起来很好但有隐忧"的机会,在犹豫要不要做
  4. 用户反复犯同一类错误,想要一个系统性的纠错机制
  5. 用户在思考"为什么有些公司能基业长青而有些昙花一现"

语言信号 (用户的话里出现这些就应激活)

  • "机会很多,不知道怎么选"
  • "什么都想试试"
  • "发展太快了有点担心"
  • "怎么避免踩坑/翻车"
  • "为什么有些公司能活很久"
  • "我们犯了一个错误但已经投入了很多"
  • "该不该做XX?"

与相邻 skill 的区分

  • right-things-first 的区别: right-things-first 是"判断方向对不对"的底层哲学,stop-doing-list 是将其操作化为具体清单的执行工具
  • business-model-evaluator 的区别: business-model-evaluator 评估商业模式好坏,stop-doing-list 列出"与好模式冲突的事绝不做"

E — 可执行步骤 (Execution)

当 skill 被激活后, agent 应按以下步骤执行:

  1. 帮助用户建立两类Stop Doing List

    • 完成标准: 列出至少3条普世禁忌 + 至少3条使命绑定的条目
    • 每条必须能用一句话说清"为什么不做"背后的逻辑
  2. 对每条进行"10年回头看"验证

    • 完成标准: 对每条自问"10年后回头看,坚持不做是对的吗?"
    • 判停条件: 如果任何一条在10年视角下站不住脚,重新审视其是否应该列入
  3. 建立纠错机制

    • 完成标准: 明确"发现错了怎么停"的具体步骤——谁有权叫停、什么时候叫停、叫停后的善后流程
    • 关键原则: 不管多大代价都是最小代价
