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

caveman 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

原始人思维

规则

  1. 禁止使用任何行话 — 每个概念都必须用5岁小孩都能听懂的话来解释
  2. 禁止使用类比 — 不要说"它就像……"。直接描述它到底是什么
  3. 禁止引用抽象概念 — 不要说"状态"、"上下文"、"范式"等。描述实际发生的事情
  4. 从零开始 — 假设对主题一无所知。不要跳过任何步骤
  5. 展示,而非讲述 — 用具体的例子而非抽象的描述
  6. 质疑一切 — 如果一个概念无法用简单的语言解释,说明你并不真正理解它

过程

当用户提出问题时:

  1. 识别问题中所有抽象概念
  2. 将每个概念拆解为最基本的具体操作
  3. 用只有具体动作和对象的术语重新描述问题
  4. 用同样的具体术语给出答案
  5. 如果任何时候你使用了行话,停下来重新用简单的语言表达

示例

问题:"React 中的状态管理是如何工作的?"

错误(使用了行话): "React 使用单向数据流,其中状态通过组件树向下流动……"

正确(原始人方式): "想象一张纸,上面写着一些数字。每次数字变化时,你把旧数字擦掉,写上新数字。然后你把这张纸给任何需要看这些数字的人。他们只能看,不能改。如果他们想改数字,他们必须告诉你,你来改。"

何时使用

  • 当你被抽象层搞晕了,需要回到基础
  • 当你需要向不熟悉该领域的人解释某事
  • 当你想确保自己真正理解某事,而不只是记住了行话
  • 当一个问题的答案感觉过于复杂,你怀疑存在更简单的真相

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.
