  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 1 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by ace3000chao on GitHub. Read the source before you install it.

Installation

Install the Complexity Equation AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
    https://github.com/ace3000chao/book2startup/tree/master/ScalingUp-skills/complexity-equation
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/ace3000chao/book2startup.git /tmp/book2startup
mkdir -p .claude/skills
cp -r /tmp/book2startup/ScalingUp-skills/complexity-equation .claude/skills/complexity-equation
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Complexity Equation in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Complexity Equation on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Complexity Equation is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Complexity Equation(复杂度乘法方程)

R — 原文 (Reading)

"Add a third person, and the degree of complexity triples from two to six. Add a fourth, and it quadruples to 24. Expanding from three to four people grows the team only 33%, yet complexity may increase 400%."

— Vern Harnish, Scaling Up, 第2章 Barriers


I — 方法论骨架 (Interpretation)

复杂度乘法方程揭示了企业扩张的隐性代价:人数线性增长,复杂度指数增长。

公式的本质:每增加一个人,与所有人的沟通节点都要重新计算。 两个人=1条关系;三个人=3条关系;四个人=6条关系;五个人=10条关系。 这叫"组合数增长"——n个人产生的连接数 = n(n-1)/2。

数字说话:

  • 2人 → 1连接
  • 3人 → 3连接(+200%)
  • 4人 → 6连接(+100%,但团队只增33%)
  • 5人 → 10连接
  • 10人 → 45连接

关键洞察:增长不是问题,缺乏管理增长的系统才是问题。 复杂度不是要不要面对的选项,而是成长的必然副产品。 解决方案不是"不增长",而是"提前建立消化复杂度的机制": 流程(Process)、规则(Disciplines)、沟通节奏(Rhythm)。


A1 — 书中的应用 (Past Application)

案例 1: 团队从3人到4人的"死亡陷阱"

  • 问题: 3人团队运转流畅,加了第4个"聪明人"后反而频繁开会、协调成本暴增
  • 方法论的使用: 用复杂度公式解释——不是第4个人不行,是连接数从3跳到6, 团队没有为此准备额外的流程和沟通机制
  • 结论: "4人门槛"需要引入明确的会议节奏和决策流程
  • 结果: 创始团队开始重视"加人不加乱"的组织设计

案例 2: 30人扩张到50人的中层管理危机

  • 问题: 快速扩张期,管理层抱怨"信息传不下去",部门墙越来越厚
  • 方法论的使用: 50人产生的连接数是1225,30人是435——人增加了67%, 连接数增加了近3倍。没有对应的信息流通机制,必然出现失真
  • 结论: 在这个规模必须引入结构化的沟通机制(周会、简报、可视化看板)
  • 结果: 引入Rockefeller Habits中的会议节奏工具,情况显著改善

案例 3: 复杂度的"隐性税"

  • 问题: 创始人抱怨"我明明雇了更多人来分担,怎么我还是这么累"
  • 方法论的使用: 展示数字:6人团队有15条连接,每条连接都在消耗 创始人的协调能量。更多人意味着更多连接,更多连接意味着更多潜在冲突和决策节点
  • 结论: 解决方式不是减人,而是建立不依赖创始人的决策系统
  • 结果: 创始人对"系统化"而非"靠人"有了全新理解

A2 — 触发场景 (Future Trigger) ★

用户会在什么情境下需要这个 skill?

  1. 团队从3-5人向10人以上扩张的阶段——开始感觉到协调成本上升, 但还没意识到这是结构性的
  2. 创始人在"要不要招人"的问题上纠结——感觉招了人效率反而下降, 怀疑是不是招错了人,而不是系统设计问题
  3. 公司出现"部门墙"或"沟通断层"——部门之间互相甩锅, 信息在传递过程中失真或消失
  4. 在做组织架构设计或汇报线调整——想要理解增加一个层级 或者增设一个部门会对复杂度产生什么影响
  5. 讨论"公司可不可以再快一点扩张"——需要量化理解 扩张速度与组织消化能力之间的关系

语言信号 (用户的话里出现这些就应激活)

  • "我们人也不多啊,怎么感觉协调起来这么累?"
  • "加了一个人之后好像更慢了,是不是招错了?"
  • "部门之间好像有墙,信息传着传着就没了"
  • "我一个人扛不住了,是不是该招个副总?"
  • "增长太快是不是有问题?要不要放慢脚步?"
  • "三个人干得挺好,加了第四个反而出问题了"

与相邻 skill 的区分

  • 与 Growth Paradox(成长悖论) 的区别: 成长悖论是"为什么越大越累" 的哲学层面解释;复杂度方程是这个悖论的数学层面量化工具
  • 与 PACe(流程问责表) 的区别: PACe是复杂度管理的具体落地工具, 复杂度方程是"为什么要用PACe"的原因解释
  • 与 Rockefeller Habits 的区别: Rockefeller Habits是复杂度管理的 一套具体习惯清单;复杂度方程是这些习惯存在的理论依据

E — 可执行步骤 (Execution)

当 skill 被激活后,agent 应按以下步骤执行:

  1. 【量化现状】计算当前团队的连接数

    • 公式:连接数 = n(n-1)/2(n=总人数)
    • 问用户:"你现在团队有多少人?" → 计算并展示连接数
    • 完成标准: 用户看到连接数,理解"为什么现在协调成本这么高"
  2. 【预测未来】模拟扩张后的复杂度增长

    • 问:"如果你计划扩张到X人,连接数会变成多少?"
    • 计算并对比:现在是多少,扩张后是多少,增长百分比
    • 判停条件: 若用户说"现在还早",则聚焦当前规模,不需要预测
  3. 【制定对策】引入复杂度消化机制

    • 每个连接本质上需要三类机制之一来消化: ① 流程(标准化,减少临时沟通需求) ② 节奏(固定会议/周报,让信息定期流通) ③ 规则(明确谁决策什么,减少关系协调)
    • 根据用户当前痛点,选择优先级最高的1-2个机制落地
    • 完成标准: 用户理解"加流程不是管束,而是降低每个人的协调负担", 并产出一个具体的"下月引入机制"清单

B — 边界 (Boundary) ★

不要在以下情况使用此 skill

  • 个人时间管理问题:一个人管很多任务,复杂度方程不适用—— 这是个人认知负荷问题,不是人际连接问题
  • 10人以下极度扁平的小团队:此时连接数还处于可管理的范围, 不需要过度工程化;这个skill的预警价值大于干预价值
  • 纯创意/研发类工作:当团队产出主要依赖少数人的深度思考而非协作时, 复杂度方程的意义打折——不是所有连接都能产生价值

作者在书中警告的失败模式

  • 用"增加人手"解决复杂度问题:实际上增加了更多连接, 让问题更严重;正确的应对是增加"消化复杂度的机制"
  • 过早引入复杂组织架构:在连接数还很低时就设立多层汇报线, 人为制造不必要的连接,增加复杂度而非管理复杂度
  • 认为"我们公司不一样":创始人总觉得自己的团队特殊, 可以绕过复杂度规律;但这个规律是数学性质的,不以行业为转移

作者的盲点 / 时代局限

  • 原书对"远程工作/异步协作"对复杂度的影响没有充分讨论; 远程团队的部分连接转为异步,连接质量而非连接数量成为更关键的变量
  • 方程是静态快照,没有考虑"连接强度"差异—— 有些连接是高价值的深度协作,有些只是低价值的例行通知
  • 对"复杂度爆炸的临界点"没有给出精确的人数阈值; 不同文化、不同流程成熟度的企业临界点差异很大

容易混淆的邻近方法论

  • 彼得原理(组织层级增加导致的问题):关注"人放在错误层级", 不关注连接数本身
  • 组织生命周期理论(Greiner):描述的是成长阶段与危机的对应关系, 复杂度方程是这个理论中某个危机的解释机制而非完整框架
  • Mckinsey 7-S:关注组织内部一致性,复杂度方程关注 人际连接数量的可量化维度,维度不同但互补

Frequently asked questions

What does the Complexity Equation AI skill do?

当团队扩张后效率反而下降、沟通成本暴增时;当创始人不理解"为什么人多了 反而更慢"时;当企业在扩张和稳定之间犹豫不决时;当组织设计要做调整时。 触发信号:"三个人干得挺好的,加了第四个人反而乱了?"、"部门越来越多, 协调越来越难"、"增长要不要放缓?人多了是不是有问题?" 不适用于:个人层面的时间管理问题、初创期人数极少时的线性复杂度场景。

Why use Complexity Equation on TypingMind?

Because you install it once and use it with any model. Complexity Equation is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Complexity Equation in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/ace3000chao/book2startup/tree/master/ScalingUp-skills/complexity-equation. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Complexity Equation?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Complexity Equation?

As many as you like. As long as a model supports skills, you can use Complexity Equation with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Complexity Equation AI skill free?

Yes. It is published on GitHub by ace3000chao under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
