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

clear-thinking 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.

What it actually says

Clear Thinking — 清晰思考框架

在关键时刻,你不是被知识打败——你是被「本能反应」打败。

Shane Parrish(Farnam Street 博客创始人)的核心主张:好决策不需要你更聪明,需要你在决策的那一刻不被情绪和默认反应劫持。


默认反应:四个自动模式

人在压力下会启动四种默认反应:

默认反应 表现 代价
情绪默认 生气、恐惧、焦虑时做决定 后悔
自我默认 保护自己是对的,不管事实 错失真相
社会默认 跟着多数人走 平庸
惯性默认 维持现状,不想改变 停滞

关键时刻的第一步不是做决定,是识别自己正在被哪种默认反应支配。


四步决策框架

  1. 暂停 — 不说话,不做决定。等情绪过去。
  2. 定义问题 — 我真正要解决的是什么?不是表面问题,是根问题。
  3. 收集选项 — 强迫自己列出至少三个选项。两个选项 = 假的自由。
  4. 评估后果 — 如果选错了,最坏的结果是什么?我能承受吗?

二阶思维

不要只想「做了会怎样」,想「做了之后,之后会怎样」。

一阶:吃这个蛋糕 → 快乐
二阶:吃完 → 血糖飙升 → 下午犯困 → 工作效率归零

好的决策者总是多想一步。


一句话总结

当所有人都在快速反应时,能停下来想清楚的人——赢。慢就是快。

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.
