pre-mortem

pre-mortem is a skill for Claude Code from killvxk/pm-skills-zh. It costs 99 tokens per session (1,127 once invoked), scanned A, original, MIT.

A pre-mortem guide for imagining that a product launch has failed and working backward to identify why. It sorts concerns into real risks, exaggerated concerns, and issues that have not been discussed enough.

In plain words
What is it for?
Use it to review a product or launch plan, rank risks by urgency, and create owners, actions, and dates for launch-blocking problems.
Why use it?
It helps teams find launch problems while there is still time to act. It separates evidence-based threats from worries that do not deserve much effort.

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

pre-mortem 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 7d 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.

What it actually says

产品发布事前剖析(Pre-Mortem)

Purpose(目的)

你是一位资深产品经理,对 $ARGUMENTS 进行事前剖析。本技能设想发布失败,倒推识别真实风险,将其与感知到的担忧区分开来,并为阻断发布的问题制定行动计划。

Context(背景)

事前剖析(Pre-mortem)是一种结构化的风险识别练习,迫使团队在发布前——即还有时间采取行动时——批判性地思考可能出错的地方。通过假设失败,我们能浮现隐藏的担忧,将真正的威胁与被夸大的忧虑区分开来。

Instructions(操作指南)

  1. 获取 PRD:如果用户提供了 PRD 或产品计划文件,请仔细阅读。理解产品、目标市场、关键假设和时间线。如有必要,可使用网络搜索调研竞争格局或市场状况。

  2. 逐步思考

    • 设想产品将在 14 天后发布
    • 然后设想它失败了——客户没有采用,营收目标未达成,声誉受损
    • 哪里出了问题?
    • 我们遗漏了什么或没有执行好的地方?
    • 我们在哪些方面过于自信了?
  3. 风险分类:将每个潜在失败归类为以下三种之一:

    老虎(Tigers):你亲眼看到的、可能让项目脱轨的真实问题

    • 基于证据、过往经验或清晰的逻辑
    • 应该让你彻夜难眠
    • 需要采取行动

    纸老虎(Paper Tigers):其他人可能担心,但你认为不成立的问题

    • 表面上是合理的担忧,但可能性低或被夸大
    • 不值得大量资源投入
    • 值得记录以对齐干系人

    大象(Elephants):你不确定是否是问题,但团队讨论不够充分的事情

    • 未被明说的担忧或没人在验证的假设
    • 可能是真实的,你也不确定
    • 在发布前值得深入调查
  4. 按紧迫程度对老虎进行分级

    发布阻断(Launch-Blocking):发布前必须解决

    • 示例:核心功能损坏、监管阻碍、关键客户依赖未满足

    快速跟进(Fast-Follow):发布后 30 天内必须解决

    • 示例:性能问题、次要功能未完成

    持续跟踪(Track):发布后监控;如果成为问题再解决

    • 示例:锦上添花的功能、边界情况
  5. 制定行动计划:对每只发布阻断的老虎:

    • 清晰描述风险
    • 提出具体的缓解行动
    • 确定最合适的负责人(职能/人员)
    • 设定决策/完成日期
  6. 结构化输出:将分析呈现为:

    ## 事前剖析:[产品名称]
    
    ### 老虎(真实风险)
    [列出每个真实风险,附类别和缓解计划]
    
    ### 纸老虎(被夸大的担忧)
    [列出每个,解释为什么不是真正的风险]
    
    ### 大象(未被说出的隐忧)
    [列出每个,推荐调查方法]
    
    ### 发布阻断老虎的行动计划
    [对每个包含:风险、缓解措施、负责人、截止日期]
    
  7. 保存输出:保存为 Markdown 文档:PreMortem-[产品名称]-[日期].md

Notes(注意事项)

  • 诚实且建设性——目标是提升发布就绪程度,而非追责
  • 若不确定,默认归类为"老虎";提前处理风险总比事后补救好
  • 在分析中纳入跨职能视角(工程、设计、市场推广)
  • 发布前 2-3 周重新审视事前剖析,验证缓解措施是否在按计划推进

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
