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.

Fable 5.1 $0.00099 $0.01671
Opus 5 $0.00049 $0.00835

Security

Grade A, and why

p21毋偏信自任毋自满嫉人 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.

毋偏信自任毋自满嫉人原则

R — 原文 (Reading)

"毋偏信而为奸所欺,毋自任而为气所使;毋以己之长而形人之短,毋因己之拙而忌人之能。"

— 洪应明, 《菜根谭·毋偏信自任 毋自满嫉人》


I — 方法论骨架 (Interpretation)

  1. 四种陷阱:偏信、自任、傲短、嫉能。 洪应明列举了四个认知和情绪上的陷阱。
  2. "偏信而为奸所欺"——偏信某人,会被奸诈者利用。 你信任的人可能利用你的信任。
  3. "自任而为气所使"——过度自信,会被意气所驱使。 骄傲让人做不理性的事。
  4. "以己之长形人之短"——用自己的长处比别人的短处,是傲慢的表现。
  5. "因己之拙忌人之能"——因为自己笨,就嫉妒别人的才能,是狭隘的表现。
  6. 核心:保持对自己的清醒认知,同时对他人的价值保持开放。

A1 — 书中的应用 (Past Application)

案例: 洪应明论四种认知陷阱

  • 问题: 人为什么会被骗?为什么会傲慢?为什么会嫉妒?
  • 方法论的使用: 洪应明指出四种陷阱的内在机制——偏信、自任、傲短、嫉能
  • 结论: 这些陷阱让人失去清醒,做出错误判断
  • 结果: 避免这四种陷阱的人,更容易做出正确决策

A2 — 触发场景 (Future Trigger) ★

用户会在什么情境下需要 this skill?

  1. 对某人/某事深信不疑,旁人提醒也不听时 — "我相信他,你们不要说了"、"我的判断不会错"
  2. 觉得自己特别厉害/正确,别人的意见听不进去时 — "你们都不懂"、"我的经验比你们丰富"
  3. 觉得自己不如别人,嫉妒他人的才能时 — "他有什么了不起的"、"我就是做不到他那样"
  4. 用人所长还是用己所长的决策时 — "我该自己做还是让他做?"、"我和他比谁更强?"

语言信号 (用户的话里出现这些就应激活)

  • "我相信他,不会有错的"
  • "我比他们都强"
  • "他们都不如我"
  • "他有什么了不起的"
  • "我就是做不到"
  • "没有人能骗我"

与相邻 skill 的区分

  • p27骄泰失之谦虚受益 的区别: p27是"富贵/成功后要收敛",p21是"日常中防止四种陷阱";p27有时机性,p21是普遍性
  • p03心地光明才华韫藏 的区别: p03是"才华要藏",p21是"不能自满嫉妒";p03关注才华,p21关注态度

E — 可执行步骤 (Execution)

当 skill 被激活后,agent 应按以下步骤执行:

  1. 识别用户陷入了哪种陷阱:偏信?自任?傲短?嫉能?

    • 完成标准: 用户明确自己属于哪一种
  2. 用具体问题检测:

    • 偏信:"如果你错了,你愿意承认吗?"
    • 自任:"如果你的判断是错的,谁来提醒你?"
    • 傲短:"你确定你的长处比他的短处重要吗?"
    • 嫉能:"他的能力能不能为你所用?"
  3. "毋偏信/自任/傲短/嫉能"的替代方案:

    • 偏信→兼听
    • 自任→开放
    • 傲短→尊重
    • 嫉能→学习

B — 边界 (Boundary) ★

不要在以下情况使用此 skill

  • 基于经验的自信判断:在某些领域,经验积累后的判断力是必要的,不能因为"不自任"而过度怀疑自己
  • 健康竞争场景:正当竞争不是嫉妒,合理的自我评估不是自满
  • 需要果断决策的场景:过度"兼听"可能让人犹豫不决

作者在书中警告的失败模式

  • 偏信自任(来自本原则):偏信他人而为奸所欺,自负而为气所使
  • 机制:被信任的人利用,被骄傲冲昏头脑

作者的盲点 / 时代局限

  • 某些领域需要"偏信"(信任专家),不是所有"偏信"都是坏的
  • 完全的"兼听"可能让人失去主见,需要平衡

容易混淆的邻近方法论

  • 骄泰失之(p27):p27强调"成功后收敛",p21强调"日常中避免四种陷阱";p27是时机性的,p21是持续性的
  • 德主才奴(p22):p22是"德为主,才为奴",p21是"不自满、不嫉妒";p22更根本
