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

f05 filth-to-purity 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 9d 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.

净从秽生转化框架

R — 原文 (Reading)

"粪虫至秽,变为蝉而饮露于秋风;腐草无光,化为萤而跃彩于夏月。因知洁常自污出,明每从晦生也。"

— 洪应明, 菜根谭·净从秽生 明从暗出


I — 方法论骨架 (Interpretation)

污秽不是终点,是转化的原材料。

这个框架的核心洞见是:洁净与污秽、光明与黑暗不是对立的两极,而是可以互相转化的条件性存在。粪虫在污秽中生长,却能化为蝉,在秋风中饮露;腐草在无光中沉睡,却能化为萤火虫,在夏夜跃彩。逆境(污秽、黑暗)不是人生的死胡同,而是某种转化的必经阶段。

方法论本质:

  1. 接受"此时此地"的污秽:不要急着逃离或否认现状,因为逃离本身就是在拒绝转化。
  2. 寻找转化条件:转化需要时间、态度、行动——不是"立即变干净",而是"在污秽中积累转化所需的能量"。
  3. 相信转化的可能性:污秽→洁净、黑暗→光明,是需要时间的自然过程,不能急,但也不能放弃。

一句话总结: 此刻的污秽,可能是未来纯净的养料。重要的不是"我现在有多脏",而是"我是否在创造转化的条件"。


A1 — 书中的应用 (Past Application)

案例 1: 孟母三迁

  • 问题: 孟子和母亲最初居住在墓地附近,孟子学的是丧葬跪拜;搬到市场旁,孟子学的是买卖争吵。环境对人的影响极为负面。
  • 方法论的使用: 孟母没有抱怨"这地方太糟糕了",也没有"逆来顺受"认命,而是主动识别"污秽"的环境(墓地、市场)不适宜孩子成长,主动寻求"转化条件"——搬到学堂附近,让孟子接触到好的环境和人群。
  • 结论: 洁净不是逃避污秽,而是在污秽中寻找创造转化条件的路径。
  • 结果: 孟子成为儒家亚圣,"孟母三迁"成为环境转化、个人成长的经典案例。

案例 2: 姜子牙钓鱼愿者上钩

  • 问题: 姜子牙年迈,空有一身才华,却在渭水之滨垂钓为生,看似处于人生最低谷——无钱无势无名,是"腐草无光"的处境。
  • 方法论的使用: 姜子牙没有因为处境卑微而放弃,而是以"愿者上钩"的姿态等待时机——他把低谷期当成积累和等待的阶段,不断修炼自己的能力,等待周文王这个"转化条件"出现。
  • 结论: 在人生的"晦"处(无光期),不是要逃离,而是要持续积累,等待转化条件的成熟。
  • 结果: 姜子牙被周文王发现,辅佐周朝八百年基业,成为"太公望"。腐草化为萤火虫的故事,在他身上真实上演。

A2 — 触发场景 (Future Trigger) ★

用户会在什么情境下需要这个 skill?

  1. 处于人生低谷:失业、失恋、创业失败、考试落榜,觉得"这辈子就这样了",看不到希望。
  2. 环境无法改变:暂时无法换工作、换城市、离开一段有毒的关系,但又必须在这个环境中继续待着。
  3. 感觉"太脏了不可能有好结果":用户在污秽/混乱的环境中感到绝望,认为这个环境决定了命运,看不到任何正向可能性。
  4. 想逃离但无处可去:用户在污秽的现状中挣扎,但既无法改变现状也无法离开,不知道该怎么办。
  5. 做决定前评估转化可能性:用户面临是否要"放弃现在重新开始"的决策,需要一个判断框架来决定是转化还是逃离。

语言信号 (用户的话里出现这些就应激活)

  • "我觉得现在太绝望了"
  • "这个环境太脏了,还能有什么好"
  • "我这辈子就这样了吗"
  • "现在的处境太糟糕了,看不到希望"
  • "我想离开但走不了"
  • "这里的人都这样,我也不可能例外"
  • "这些经历会不会毁了我"
  • "什么时候才能熬出头"

与相邻 skill 的区分

  • f07(见微知著守正待时) 的区别:f07 讲"时机不到要等",强调的是"时机";f05 讲"污秽中可以转化",强调的是"条件"。f07 更偏时机等待,f05 更偏主动创造转化。
  • f13(逆增上缘修行框架) 的区别:f13 讲"逆境是修行的机会"(接受逆境),f05 讲"逆境中可以转化为净"(改造逆境)。f13 是认知框架,f05 是转化路径。

E — 可执行步骤 (Execution)

当 skill 被激活后,agent 应按以下步骤执行:

  1. 确认当前处境的"污秽度"
    • 完成标准: 明确说出"你现在处于什么状态"(低谷/困境/有毒环境),并用"1-10"评估这个状态的恶劣程度(10是最恶劣)。
    • 判停条件: 若用户评估<3,说明并非真正的"污秽"处境,此框架适用性低,应转介更轻量的skill。
