What it does

Pre Mortem is an agent skill from killvxk/pm-skills-zh. 对 PRD（产品需求文档）或发布计划进行事前剖析（Pre-mortem）。将风险分类为老虎（真实问题）、纸老虎（被夸大的担忧）和大象（未被说出的隐忧），并按发布阻断、快速跟进或持续跟踪进行分级。适用于发布准备、对产品计划进行压力测试，或识别可能出错的地方。

Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Product & Project Management, covering PRD writing. The repository describes itself as: PM Skills Marketplace 简体中文版 - 65个产品经理技能和36个工作流，翻译自 https://github.com/phuryn/pm-skills/. The licence is MIT.

When your agent uses it

  • Tasks that involve PRD writing

Example prompts

  • “/pre-mortem”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  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
  3. 风险分类：将每个潜在失败归类为以下三种之一
  4. 按紧迫程度对老虎进行分级
  5. 制定行动计划：对每只发布阻断的老虎
  6. 结构化输出：将分析呈现为
  7. 保存输出：保存为 Markdown 文档：PreMortem-[产品名称]-[日期].md

What it can do on your machine

Read from SKILL.md and the folder at commit 5179784. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • productcompass.pm

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Pre Mortem loads about 475 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 73 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~35
When it runs · the whole SKILL.md, loaded when a task matches
~475

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

对 PRD（产品需求文档）或发布计划进行事前剖析（Pre-mortem）。将风险分类为老虎（真实问题）、纸老虎（被夸大的担忧）和大象（未被说出的隐忧），并按发布阻断、快速跟进或持续跟踪进行分级。适用于发布准备、对产品计划进行压力测试，或识别可能出错的地方。

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
