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

f21-mindless-freedom 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.

断绝思虑逍遥框架

R — 原文 (Reading)

"斗室中,万虑都捐,说甚画栋飞云、珠帘卷雨;三杯后,一真自得,唯知素琴横月、短笛吟风。"

— 洪应明, 断绝思虑 光风霁月


I — 方法论骨架 (Interpretation)

这是极简减法操作法——不是增加什么来获得自由,而是减少什么来获得自由。

核心公式:简到极致 = 真境

三个递减层次:

  1. 万虑都捐:把一切忧虑、挂碍、算计全部清除。不是选择性放下,是全部捐出。
  2. 环境降到最低:不需要画栋飞云的豪宅,斗室(小屋)就够了。
  3. 欲望降到最低:不需要锦衣玉食,三杯淡酒、一把琴、一支笛就够了。

推论:真正的快乐和自由,不需要复杂的条件。条件越复杂,离真越远。这与"成功需要很多资源"的常识相反——真正的逍遥,是有勇气和能力过简单生活的人才能达到的境界。


A1 — 书中的应用 (Past Application)

案例 1: 刘禹锡《陋室铭》

  • 问题: 刘禹锡被贬官,居于破旧陋室,物质条件极差
  • 方法论的使用: 他没有追求更好的物质条件,而是以"斯是陋室,惟吾德馨"自处——物质简陋但精神充实
  • 结论: 环境简陋不等于内心简陋,心正则境不陋
  • 结果: 《陋室铭》成为千古名篇,"陋室"成为高洁志趣的象征

案例 2: 陶渊明桃花源记

  • 问题: 陶渊明身处乱世,仕途不得志,对现实政治失望
  • 方法论的使用: 他不是去改造现实或谋取更高的官职,而是彻底"断绝思虑"——归隐田园,过最简单的农耕生活
  • 结论: "桃源犬吠,桑间鸡鸣"——最淳朴的生活才是真境
  • 结果: 陶渊明成为中国隐逸文化的精神偶像,其诗歌开创了田园诗派

案例 3: 姜子牙钓鱼愿者上钩

  • 问题: 姜子牙空有一身才华,却长期无人赏识,处境困顿
  • 方法论的使用: 他没有拼命钻营或自我推销,而是"以静制动"——在江边钓鱼,静待时机
  • 结论: 不需要主动追逐,最简单的存在方式即可
  • 结果: 最终遇到周文王,成就一番功业

A2 — 触发场景 (Future Trigger) ★

用户会在什么情境下需要这个 skill?

  1. 思维反刍循环:对某件事反复思考停不下来(睡前/凌晨/休息时),严重影响睡眠和情绪
  2. 条件依赖症:总觉得"等我有了XX条件就能开始了"——买了设备/租了办公室/请了人,但实际上行动力仍然为零
  3. 选择瘫痪:面对太多选项(职业选择/投资决策/人生方向),反而无法行动
  4. 精神消耗过度:总觉得累,但说不出具体在累什么;无法真正放松

语言信号 (用户的话里出现这些就应激活)

  • "我脑子停不下来,一直在想同一件事"
  • "想太多做不下去"
  • "怎么才能真正放下"
  • "等我有了XX就能……"(条件依赖句式)
  • "我需要好好想想"(但已经想了很久)
  • "每天脑子里装太多东西了"
  • "感觉被压得喘不过气"
  • "我现在状态不对,需要调整"

与相邻 skill 的区分

  • f19 忙里偷闲 闹中取静 的区别:f19是在忙乱中保持节奏(资源管理),本框架是彻底清空(减法革命)
  • f12 一念转魔成佛框架 的区别:f12是在情绪腾沸的瞬间"转念",本框架是系统性的"万虑都捐"

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"条件清单"

    • 完成标准: 用户列出"我认为做成X事需要的所有条件",然后逐条问自己:"如果没有这条,我真的做不成吗?"——大多数条件答案是"其实没有也行"
  2. 执行"减法三问"

    • 完成标准: 用户回答三个问题: a. "我现在最不需要担心的一件事是什么?"(挑最大的那个放下) b. "我一直在想的那件事,1年后还重要吗?"(如果否,现在为什么要想?) c. "如果我现在一无所有,只能留一件事,留什么?"(找到真正的核心)
    • 判停条件: 若用户处于真实匮乏状态(基本生存需求未满足),则先满足基本需求,不要强行"减法"
  3. 设定"最小可执行单元"

    • 完成标准: 基于步骤2的发现,用户确定一个"不需要任何条件,现在就能开始"的最小的行动

B — 边界 (Boundary) ★

不要在以下情况使用此 skill

  • 用户正处于真实危机或紧急情况(需要行动,而不是放下)——应该用f33 不动声色应变框架
  • 用户的基本生活需求未得到满足(缺钱/缺安全感),强行"万虑都捐"是自欺欺人
  • 需要深度思考的创造性工作(写方案/策划/学习)——此时不应减法,而应用f19管理节奏
  • 抑郁症患者过度思考——需要专业干预,不是减法能解决的
