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 | $0.00124 | $0.03762 |
| Opus 5 | $0.00062 | $0.01881 |
| Sonnet 5 | $0.00025 | $0.00752 |
| Haiku 4.5 | $0.00012 | $0.00376 |
Grade A, and why
strategy-two-tests 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 6d 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.

Strategy Two Tests(战略必须通过两个测试)
R — 原文 (Reading)
"You don't have a real strategy if it doesn't pass two tests: First, what you're planning to do really matters to enough customers; and second, it differentiates you from your competition."
— Verne Harnish, Scaling Up, 第1章 (引用 Gary Hamel)
I — 方法论骨架 (Interpretation)
Gary Hamel(世界顶级战略大师)的定义:真正的战略必须同时通过两个测试
Scaling Up引用Gary Hamel的核心观点:大多数公司有的是"计划"、"目标"或"愿景",但不是真正的"战略"。Hamel认为,战略不是"我们要去哪里",而是"我们如何在竞争中赢"。
两个测试的定义:
测试一:对足够多的客户真的重要(Customer Mattering Test)
- 一个战略必须对足够多的目标客户真的重要——不是"有点帮助",不是"还不错",而是"如果你没有这个,客户会非常不满意"
- 这个测试的意图是防止"战略过于细分"(只对极少数客户有价值)或"战略过于泛泛"(对谁都没有真正吸引力)
- 检验方法:问"如果我们停止做这件事,现有客户会怎样?"——如果答案是"他们会注意到并流失",说明这件事真的重要;如果答案是"他们可能不会发现",说明这件事根本不是战略
测试二:能差异化于竞争对手(Competitive Differentiation Test)
- 一个战略必须让你在竞争中与众不同——不是"比竞争对手好一点点",而是"竞争对手如果不复制你这个,他们就无法与你竞争"
- 这个测试防止"战略同质化"——你和竞争对手做的事情几乎一样,只有价格或执行力差异,那不是战略,是竞争
- 检验方法:问"竞争对手最害怕我们做什么?"——如果答不出来,说明你可能没有真正的差异化战略
两个测试的关系:
- 通过测试一但未通过测试二:你有"好的产品"但没有"战略"——竞争对手会慢慢蚕食你的优势
- 通过测试二但未通过测试一:你有"差异点"但市场太小——无法支撑企业Scaling
- 同时通过两个测试:真正的战略——既服务足够大的市场,又能差异化于竞争
常见的失败模式:
- "我们有战略"但只通过测试一:产品/服务有价值但没有差异化,价格战或执行力竞争
- "我们有战略"但只通过测试二:差异化足够但细分市场太小,无法支撑规模化增长
- "我们有战略"但两个测试都没通过:空洞的计划,既没有客户真的在乎,也没有差异化
A1 — 书中的应用 (Past Application)
案例 1: 苹果的"测试一二通过"
- 问题: 乔布斯回归后的苹果,PC市场份额始终在5%以下,但苹果在"个人电脑"市场仍然活着并繁荣。为什么?
- 方法论的使用: 用两个测试检验苹果1998年后的战略——"让普通消费者能使用强大的个人计算设备"(测试一:对足够多客户真的重要?——是的,苹果的iMac和后来的iPhone瞄准的不是极客,而是大众消费者,他们真的在乎"易用性");"设计与用户体验作为核心竞争力"(测试二:差异化于竞争对手?——是的,戴尔和惠普都在用英特尔芯片和Windows,苹果用自己的芯片和操作系统,设计和体验是竞争对手难以快速复制的)。
- 结论: 苹果的战略同时通过两个测试,所以是真正的战略。PC市场份额5%不是失败,而是苹果主动选择了小而精的市场(而不是大众市场),但战略本身仍然是服务足够大的人群(消费者市场的"高端")。
- 结果: 苹果成为全球市值最高的公司之一,在乔布斯回归后20年内增长超过100倍。
案例 2: 西南航空的"测试一二通过"
- 问题: 90年代,几乎所有大型航空公司都在枢纽-辐射网络模型(Hub & Spoke)中竞争,每家航空公司的战略几乎一样:覆盖尽可能多的城市,提供尽可能多的航班选择。西南航空则坚持"点对点"短途航线。
- 方法论的使用: 用两个测试检验西南航空的战略——测试一:低成本短途直航对客户真的重要吗?(是的,对于短途旅客(2小时以内),直航比中转节省3-4小时,时间就是钱);测试二:这个战略差异化于竞争对手吗?(是的,枢纽-辐射航空公司无法在短途直航上与西南竞争,因为他们的成本结构(高劳动力成本、多机型切换成本)使短途直飞不经济)。
- 结论: 西南航空的战略是真正的战略:它对足够多的客户(短途旅客)真的重要,且竞争对手即使看到了也无法复制(成本结构是结构性障碍)。
- 结果: 西南航空连续47年盈利,是美国航空业历史上唯一一家没有破产的大型航空公司。
What ships with it

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.

strategy-two-tests is a skill published in the GitHub repository ace3000chao/book2startup (76 stars, last pushed 4mo ago), licensed MIT. It adds 124 tokens to every session and 3,762 once invoked, about $0.0006 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.
