Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00088 | $0.02446 |
| Opus 5 | $0.00044 | $0.01223 |
| Sonnet 5 | $0.00018 | $0.00489 |
| Haiku 4.5 | $0.00009 | $0.00245 |
Grade A, and why
growth-sucks-cash 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.

Growth Sucks Cash(增长吃现金)
R — 原文 (Reading)
"Growth sucks cash. This is the first law of entrepreneurial gravity."
— Verne Harnish, Scaling Up, Chapter 1 & Chapter 12
增长是创业引力的第一定律。任何快速增长的企业都在持续消耗现金——不是因为管理不善,而是增长的本质就是如此。营业收入增长越快,应收账款和库存的垫资需求就越大。创业者必须像关注利润表一样高度关注现金流量表。
I — 方法论骨架 (Interpretation)
增长吃现金,这一"创业引力定律"意味着:
- 增长必然消耗现金 — 规模扩张天然带来应收账款、库存、人力成本的提前垫资,这不是管理失误,是物理规律。
- 增长速度越快,现金缺口越大 — 高增长企业往往表面风光,但现金流最紧张;增速放慢反而让现金喘口气。
- 现金流是比利润更重要的生存指标 — 企业可以亏损多年不倒闭,但现金断链立刻死亡(参考京东自建物流前多年的亏损运营)。
- 决策必须同时评估现金流影响 — 每一次扩团队、上新线、进入新市场,都必须用现金流视角审视,而非只看收入或利润。
- 预测现金流是CEO的必修课 — 需要按月预测现金收支,建立现金"跑道"(runway)概念——账上现金还能撑几个月。
- 融资节奏要早于资金枯竭 — 不要等现金见底才去融资,那时候你已经失去谈判筹码。
A1 — 书中的应用 (Past Application)
案例 1: 快速扩张的餐饮连锁
- 问题: 某餐饮品牌在获得融资后加速扩张,门店数量翻倍,但总部需要为新店垫付装修款、押金和前几个月的运营亏损。
- 方法论的使用: Harnish指出,表面营收增长掩盖了加盟商账期、新店爬坡期和供应链垫资的三重现金压力。
- 结论: 扩张速度必须匹配融资节奏和经营性现金流的承载能力。
- 结果: 该品牌在第三年因现金断链被迫关闭半数新店,创始人失去控制权。
案例 2: SaaS企业的递延收入悖论
- 问题: SaaS公司年营收翻倍增长,但客户按年付费带来的递延收入在财务报表上尚未确认,导致经营现金流远低于净利润。
- 方法论的使用: 书中强调,订阅制企业的现金流实际上优于利润表现——预收款项在现金到账时记录为负债(递延收入),随后在服务交付时逐步确认为收入。
- 结论: 高增长SaaS公司应重点关注"经营现金流"而非净利润,同时用ARR(年度经常性收入)衡量增长质量。
- 结果: 关注现金流的创始人提前启动了新一轮融资,保住了18个月的现金跑道。
案例 3: 零售连锁的库存黑洞
- 问题: 某零售连锁为抓住节日旺季,在Q4大幅备货,库存翻了三倍,但销售不及预期导致库存积压占用现金。
- 方法论的使用: Harnish提醒:库存不是资产,是冻结的现金。每增加一件库存,就少了一份可用于支付工资或供应商账款的现金。
- 结论: 库存管理是现金管理的核心战场,需要与供应商谈判更有利的付款条件(如60天或90天账期)来对冲库存占用的现金压力。
- 结果: 该公司次年开始实施库存周转率月度考核,现金周转天数缩短40天。
A2 — 触发场景 (Future Trigger) ★
用户会在什么情境下需要这个 skill?
- 准备融资或接受投资时 — 投资人在DD阶段会追问现金流模型,创始人需要清晰回答"这笔钱能撑多久"。
- 制定增长计划时 — 每当提出"我们要进军X市场/扩招Y人/新增Z产品线"时,现金流必须同步评估。
- 发现账上现金快速下降但收入增长时 — 典型的"增长甜蜜期"陷阱,表面业绩好但现金在恶化。
- 遇到付款周期谈判或客户账期纠纷时 — 需要站在现金流全局说服团队接受更严格的付款条件。
- 公司即将达到现金临界点前 — 现金跑道不足6个月时,创始人必须做出取舍决策。
语言信号 (用户的话里出现这些就应激活)
- "我们有很好的增长,但账上钱越来越少了"
- "这笔融资进来以后够烧多久?"
- "要不要加速扩张?"
- "客户账期太长,资金周转不开"
- "收入翻倍了,为什么现金流还是负的?"
与相邻 skill 的区分
- 与
fewer-people-higher-pay的区别: 那是从人力成本结构优化现金;本skill是从增长与现金的引力关系出发,适用范围更广。 - 与
cashflow-vs-profit(现金流比利润更重要)的区别: 那是同书p29的近邻方法论,本skill强调增长是现金消耗的发动机,是因;p29强调现金流是生存指标,是果;两者高度协同,可组合使用。

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.

growth-sucks-cash is a skill published in the GitHub repository ace3000chao/book2startup (80 stars, last pushed 4mo ago), licensed MIT. It adds 88 tokens to every session and 2,446 once invoked, about $0.0004 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 2026-08-30.
