Fear And Greed

Q: What does the Fear And Greed AI skill do?

用户面对市场极端情绪时需要做出逆向来决策。当所有人都在买入/卖出、市场处于极端乐观/悲观时。 语言信号："所有人都在赚钱"/"这次不一样"/"市场要崩了要不要全卖"/"再不买就来不及了" 不适用于：正常市场环境下的投资决策、纯基本面分析。

Q: Why use Fear And Greed on TypingMind?

Because you install it once and use it with any model. Fear And Greed is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

Q: How do I install Fear And Greed in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/kangarooking/buffett-letters-skill/tree/main/fear-and-greed. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Q: Which AI models can use Fear And Greed?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

Q: How many AI models can I use with Fear And Greed?

As many as you like. As long as a model supports skills, you can use Fear And Greed with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Q: Is the Fear And Greed AI skill free?

Yes. It is published on GitHub by kangarooking under the MIT license. You only pay your own AI provider for the tokens you use.

Q: What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

Q: How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.

Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
1 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by kangarooking on GitHub. Read the source before you install it.

Installation

Install the Fear And Greed AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/kangarooking/buffett-letters-skill/tree/main/fear-and-greed
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/kangarooking/buffett-letters-skill.git /tmp/buffett-letters-skill
mkdir -p .claude/skills
cp -r /tmp/buffett-letters-skill/fear-and-greed .claude/skills/fear-and-greed

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Fear And Greed in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Fear And Greed on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Fear And Greed is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

恐惧与贪婪逆向

R — 原文 (Reading)

"We simply attempt to be fearful when others are greedy and to be greedy only when others are fearful."

— Warren Buffett, 1986年信

I — 方法论骨架 (Interpretation)

不是简单的"反向操作"，而是一个基于内在价值的逆向框架：

"别人贪婪时恐惧"：当市场价格高涨、信心爆棚、故事动听 → 价格可能已超过价值 → 不买/考虑卖
"别人恐惧时贪婪"：当市场恐慌、信心崩溃、"这次完了" → 价格可能远低于价值 → 考虑买
关键前提：你必须能独立评估内在价值——否则你不知道"贪婪时"的价是贵还是便宜
这是市场先生框架的具体行动版本

A1 — 书中的应用

案例1: 2008年金融危机

问题: 市场极度恐慌，是否应该躲在现金里？
使用: 别人恐惧时贪婪——向Goldman Sachs和GE注资$8亿和$3亿
结果: 获得优厚条款和丰厚回报

案例2: 互联网泡沫

问题: 所有科技股暴涨，价值投资者严重落后
使用: 别人贪婪时恐惧——坚持不投资看不懂的科技股
结果: 避开泡沫破裂，而追逐者损失惨重

A2 — 触发场景

市场连续上涨数月，身边所有人都在赚钱
某资产从高点大幅下跌，新闻一片恐慌
有人用"这次不一样"来说服你
FOMO（怕错过）情绪强烈
想要"割肉"止损但基本面未变

语言信号

"所有人都在买XX"
"这次不一样"
"再不买就来不及了"
"完了，要崩盘了"
"我应该止损吗？"

与相邻 skill 的区分

与 mr-market 的区别：市场先生是认知框架（你怎么看价格），恐惧贪婪是行动原则（你什么时候买/卖）
与 real-conservatism 的区别：保守≠传统是关于不盲从，恐惧贪婪是关于逆向行动

E — 可执行步骤

诊断市场情绪
- 完成标准：判断当前是"极度贪婪/贪婪/中性/恐惧/极度恐惧"
- 参考信号：新闻头条情绪、身边人讨论频率、估值水平
回到内在价值（不是反向跟风）
- 完成标准：独立评估内在价值，标注当前价格与价值的差距
- 判停：如果无法评估内在价值 → 不行动（逆向≠赌博）
执行逆向操作
- 极度贪婪+价格>价值 → 减仓/不买
- 极度恐惧+价格<价值 → 加仓/买入
- 情绪极端但价值不确定 → 不行动

B — 边界

不是"永远做反向操作"——有时多数人是对的（如2009年3月后的持续上涨）
需要极强的心理素质和独立资金——被迫在最低点卖出的人不是不理性，而是没有选择
"别人恐惧"不等于"底部已到"——恐惧可以持续很久
作者盲点：巴菲特有永久资本（保险浮存金），可以在别人恐惧时持续买入——散户没有这个条件
