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

v24-利润变量控制 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 11d 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

利润变量控制:操纵杠杆驱动增长

R — 原文 (Reading)

快车道财富公式中的变量是你可以操纵的——销售数量、利润率、行业乘数。每一个变量的小幅改善,通过乘法效应,都能带来巨大的利润增长。

— MJ·德马科, 第18章

I — 方法论骨架 (Interpretation)

利润变量控制是快车道数学公式的操作指南。核心洞察:利润不是一个单一数字,而是多个变量的乘积,每个变量都是你可以操纵的杠杆。

  1. 利润公式:净利润 = 销售数量 × 利润率

  2. 三个操纵杆

    • 转化率:多少访客变成了客户?改善转化率不需要增加流量成本,是ROI最高的杠杆。
    • 流量:多少人接触到你的产品?增加流量是增长的基础,但要注意获客成本。
    • 利润率:每单赚多少钱?提高定价或降低成本都可以提升利润率。
  3. 乘法效应:三个操纵杆同时改善10%,总效果是1.1×1.1×1.1=1.33倍(33%增长)。如果每个改善20%,1.2×1.2×1.2=1.73倍(73%增长)。

  4. 行业乘数:这是第二层杠杆——净利润 × 行业乘数 = 资产价值。不同行业的乘数不同(SaaS 6-10x,传统服务2-4x)。选择高乘数行业本身就是一种杠杆。

A1 — 书中的应用 (Past Application)

德马科的优化案例:他的网站每天1.2万访问量,转化率12%,每单利润4美元。通过同时操作三个杠杆——提高转化率到15%、增加流量到2万、提升利润到4.5美元——收入从每天5760美元增长到1.35万美元。

关键洞察:他不是只做一件事,而是同时优化多个变量。单一变量的大幅改善很难,但多个变量的小幅改善叠加,效果远超预期。

A2 — 触发场景 (Future Trigger)

触发场景

  1. 你发现业务收入停滞不前时
  2. 你想提升利润但不确定从哪里入手时
  3. 你在设计定价策略时
  4. 你在评估不同增长策略的ROI时

语言信号

  • "收入上不去了"
  • "流量很大但转化率低"
  • "利润太薄了"
  • "不知道应该降价还是涨价"

与相邻技能的区分

  • vs v03(可控的无限平衡):v03解释快车道公式的原理,v24提供具体的操作方法和杠杆点。
  • vs v15(执行vs点子):v15解决"要不要行动"的问题,v24解决"行动后如何优化"的问题。

E — 可执行步骤 (Execution)

  1. 拆解你的利润公式:写出你的业务公式——净利润 = 流量 × 转化率 × 客单价 × 利润率。明确每个变量的当前值。
  2. 识别最大杠杆点:哪个变量改善空间最大?通常转化率是最容易优化的(优化落地页、简化流程、增加信任信号)。
  3. 设定30天目标:选择一个杠杆点,设定具体可量化的30天改善目标(如"转化率从3%提升到4%")。
  4. 执行A/B测试:每次只改变一个变量,测量变化前后的差异,确保改善是真实的而非随机波动。
  5. 计算资产价值:用行业乘数估算你的业务估值——净利润 × 行业乘数。这个数字可以帮你理解"每多赚1元净利润,资产价值增加多少"。
  6. 建立持续优化机制:每周花30分钟回顾三个杠杆点的变化,形成一个持续优化的循环。

B — 边界 (Boundary)

不适用场景

  • 业务极早期(还未验证需求前):先验证需求(v07),再谈优化。
  • 没有数据追踪能力的微小业务:先建立基本的追踪系统。

失败模式

  • 优化致死:在错误的方向上优化——如果产品本身没有需求,优化转化率毫无意义。
  • 过度关注短期利润:为了提升短期利润而牺牲长期品牌价值(如过度提价)。
  • 变量混淆:同时改变多个变量,无法确定哪个变化导致了结果。

作者盲点

  • 框架假设你已经有足够的数据来追踪每个变量——微小企业可能没有这个能力。
  • 行业乘数不是你能主动控制的,更多取决于市场环境和行业周期。

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.

v24-利润变量控制 is a skill published in the GitHub repository R2h1/my-book-skills (2 stars, last pushed 26d ago), licensed MIT. It adds 47 tokens to every session and 1,329 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
