What is p20放下屠刀?

A principle of keeping the larger direction in view while handling small tasks carefully. It also stresses integrity when nobody is watching and persistence during setbacks.

Use it to break a broad goal into immediate steps, check whether details support the overall aim, and keep standards during difficult periods.

Large goals can feel too distant to begin, while busy small actions can lose their purpose. This connects daily work with a clear direction.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00092	$0.01642
Opus 5	$0.00046	$0.00821
Sonnet 5	$0.00018	$0.00328
Haiku 4.5	$0.00009	$0.00164

Measured 9d ago against content hash 213636a8560e, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-12, from the pricing page.

Security

Grade A, and why

p20放下屠刀 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.

放下屠刀原则

R — 原文 (Reading)

"当怒火欲水正腾沸处，明明知得，又明明犯着，知的是谁，犯的又是谁？此处能猛然转念，邪魔便为真君矣。"

— 洪应明, 《菜根谭·放下屠刀立地成佛》

I — 方法论骨架 (Interpretation)

情绪沸腾时，人知道自己在做什么，但控制不住。 "明明知得，又明明犯着"——理智知道不对，身体和情绪却不听使唤。
"知的是谁，犯的又是谁？"——这是洪应明的点睛之笔。 理智是"知"，情绪是"犯"；它们是两个不同的"我"，不是同一个。
关键动作：猛然转念。 不是慢慢冷静，不是一再忍耐，是在一个瞬间——转念。
"邪魔便为真君"——一念之间，凡人成圣。 转念前是恶魔，转念后是君子；差别就在这一念。
不是压抑情绪，是转换焦点。 从"我要报复"转换成"这样做的后果是什么"或者其他更高视角。

A1 — 书中的应用 (Past Application)

案例: 洪应明论"猛然转念，邪魔便为真君"

问题: 当怒火欲水沸腾时，如何不被情绪控制？
方法论的使用: 洪应明指出"知"和"犯"是两个不同的主体，转念就是在它们之间创造一个空间
结论: 一念之间，从恶魔变成君子；差别不在环境，在这一念的转换
结果: 在最冲动的时候，能够"猛然转念"的人，避免了多少悲剧

A2 — 触发场景 (Future Trigger) ★

用户会在什么情境下需要 this skill?

极度愤怒，想做出伤害性行为时 — "我要让他付出代价"、"我不会让他好过的"
被仇恨/报复心占据，想要报复时 — "我恨死他了"、"他必须受到惩罚"
被欲望冲昏头脑，想要做出越界行为时 — "我知道不该，但我控制不住"
情绪失控，做出事后后悔的事之前 — "我忍不住了"、"我现在就要做"

语言信号 (用户的话里出现这些就应激活)

"我控制不住自己了"
"我现在就要做"
"我要让他付出代价"
"我恨死他了"
"我知道不该，但我停不下来"
"我忍不住了"

与相邻 skill 的区分

与 p13中和为福偏激为灾 的区别: p13是长期性格调整（避免偏激），p20是即时情绪控制（怒火时猛然转念）；p13是战略，p20是战术
与 p14谨言慎行 的区别: p14是日常谨言慎行，p20是极端情绪时的紧急制动；p14是日常驾驶，p20是紧急刹车

E — 可执行步骤 (Execution)

当 skill 被激活后，agent 应按以下步骤执行:

确认用户正处于"怒火欲水正腾沸"的极端情绪中
- 完成标准: 用户明确自己情绪极度激动
用"知的是谁，犯的又是谁"提醒用户：你的"理智"和"情绪"是不同的声音
- 完成标准: 用户意识到有另一个声音在看着自己冲动
引导"猛然转念"——让用户从"我要报复"切换到另一个视角
- 完成标准: 用户能够说出"如果我做了，后果是什么？"或者"一年后看这件事，我还会在意吗？"

B — 边界 (Boundary) ★

不要在以下情况使用此 skill

用户处于真正的危险中需要自卫：此时需要战斗反应，不是"放下屠刀"
严重心理健康危机：如重度抑郁/躁怒发作，可能需要专业医疗介入
对方正在造成客观伤害需要制止：需要实际行动保护自己和他人，不是单纯心态调整

作者在书中警告的失败模式

飞蛾扑火（来自反例ce18）：明知危险却偏扑灯火，为名利所诱自取灭亡
机制：执迷不悟，一意孤行，直到铸成大错

作者的盲点 / 时代局限

某些情绪（如被侵犯后的愤怒）是正当的，需要被认可而不是简单"放下"
"猛然转念"需要内心修炼的积累，没有一定修为的人很难做到

容易混淆的邻近方法论

中和为福(p13)：p13是避免偏激，p20是情绪失控时的紧急制动；p13是预防，p20是治疗
不恶小人(p12)：p12是事后对小人"不恶"，p20是情绪当时的"猛然转念"；p12是结果，p20是过程

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.
