decision-tripwires

decision-tripwires is a skill for Claude Code, Codex from apple-ouyang/book-to-skill. It costs 49 tokens per session (1,642 once invoked), scanned A, original, MIT.

A decision-planning method for setting clear signals that tell you when to continue, change direction, or stop investing resources in a project, investment, or relationship.

In plain words
What is it for?
Use it to set exit criteria, divide a budget or effort into review stages, establish deadlines, compare best and worst cases, and run a pre-mortem.
Why use it?
It reduces sunk-cost thinking by defining observable review points before you become committed.

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

decision-tripwires 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 12d 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.

决策触发器:提前设定止损点

任务目标

帮助用户在行动前设定明确的触发条件,对抗「自动驾驶」惯性和沉没成本陷阱。

核心问题:不是「什么价格止损」,而是「什么信号出现就重新评估」。


操作步骤

第一步:识别「自动驾驶」状态

问用户:

  • 这个项目/关系/投资,你上次主动重新评估是什么时候?
  • 如果现在从零开始,你还会做同样的选择吗?
  • 你是在主动推进,还是只是「等等看会发生什么」?

柯达的教训:1981年内部报告已预测数码威胁,但胶片生意依然有利可图,高管们选择「再等等看」——直到2012年破产。「等等看」是没有止损点的典型症状。


第二步:设定触发点表格

不要设止损价,要设触发信号。格式:

当前假设 采取行动的时机
用户不会为功能X付费 如果超过10%的用户主动询问功能X
这段关系会改善 如果3个月内没有具体改变
市场还没准备好 如果竞争对手的同类产品月活超过10万

引导用户填写自己的版本。触发点必须具体、可观测,不能是「感觉不对的时候」。


第三步:用隔断效应切分资源

把资源分成小份,每份用完都强迫重新决策:

  • 赌资实验:赌资分装10个信封 vs 放在1个信封,赌博次数显著减少
  • 饼干实验:锡箔纸单独包裹 → 24天吃完;不包裹 → 6天吃完
  • 风险投资:分轮投入,每轮都重新评估「这个假设还成立吗?」

实操:把预算/时间/精力分成3份,每份用完前必须回答:「如果现在是第一天,我还会继续投入吗?」


第四步:设截止日期

有截止日期:66%完成;无截止日期:25%完成(特沃斯基和沙菲尔研究)。

截止日期不只是催促,它是强制重新评估的节点。华为PDA流程的「冲刺过点」本质上是:到这个时间点,必须做出继续/调整/放弃的决定,不能再拖。


第五步:区间估计,不要点估计

未来不是一个点,是一个区间。

  • 直接预测准确率:45%
  • 考虑最坏+最好情况后:70%
  • 再加入基本比率参考:96%

引导用户:「这件事最坏会怎样?最好会怎样?」——两端都想清楚,比只想「最可能」更准确。


第六步:事前析误(Pre-mortem)

不要问「这件事可能会失败吗?」,而是:

「假设现在是一年后,这件事已经彻底失败了。导致失败的原因是什么?」

这种「预想式回顾」比直接想原因多产生 25% 的理由(Klein研究)。

配合 FMEA 打分:出错可能性 × 后果严重性 × 无法察觉可能性,分数最高的环节优先处理。


第七步:预演成功场景(可选)

对于高风险的成功,也要提前准备:

  • 迷你唐卡案例:预判液皂会爆火 → 提前用期权合约锁定全球塑料泵供应18个月 → 竞争对手被排出市场两年
  • 桑德拉加薪:在脑海中把谈判过了三四遍,预演老板所有可能的拒绝 → 最终成功加薪8%

问用户:「如果这件事超出预期地成功,你准备好了吗?」


输出物

引导用户产出:

  1. 触发点表格:至少3行,每行都有具体可观测的信号
  2. 资源隔断计划:把投入分成几份,每份的重新评估节点
  3. 截止日期:下次强制评估的时间
  4. Pre-mortem 清单:3-5个最可能的失败原因 + 对应预防措施

注意事项

  • 止损点不是「悲观」,是谦逊——承认自己的预测可能错误
  • Zappos 的4000美元离职提议本质上是给新员工设止损点:「如果你不确定,现在就是最低成本的退出时机」
  • 触发点设好后要写下来,不能只在脑子里——「感觉不对的时候」不算触发点
  • 对于已经深陷的项目:先做Pre-mortem,再设触发点,不要直接问「要不要继续」(沉没成本会干扰判断)
  • Van Halen 棕色 M&M 案例:David Lee Roth 在演出合同第 126 条要求后台 M&M 不能有棕色的。合同技术规格极其复杂,如果看到棕色 M&M,说明主办方没仔细读安全规格,立即触发全面设备检查。tripwire 不一定是坏消息,而是一个诊断信号——用低成本信号检测高成本风险
  • Heath 兄弟「丈夫辞职」案例:Heath 兄弟在《Decisive》中建议,不要在情绪激动时立即辞职,而是设定具体触发点——「下次老板要求我10点还在加班时,我就辞职」。这把模糊的「我受够了」转化为可观测的信号,避免冲动决策,也避免无限期忍耐
  • Heath 兄弟「成人子女回家住」案例:Heath 兄弟建议,允许成年子女搬回家时,提前设定触发点:「6个月后开始收租」或「不把所有行李搬回来,部分放储藏室」。这防止「暂时」变成「永久」——惰性会让临时安排自动续期,触发点强制重新评估
  • Bounty 纸巾营销人员案例:宝洁 Bounty 的一位营销人员被迫在实验室测试竞品纸巾,结果发现自己竟然更喜欢竞品的某些特性。这次「强制近距离观察」打破了他对 Bounty 竞争力的假设,触发了对产品定位的重新评估——有时候触发点不是数字,而是一次被迫的直接接触
