fx

Exchange rates / FX lookup workflow. Use for currency exchange rate questions (USD/CNY, EUR/CNY, etc.), “today/latest/real-time” rates, conversion requests, or when you need to cite FX numbers. Default to market mid rate unless user asks for official/bank rates. Must include source link + local update time; NEVER fabricate.

  • 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.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by JinFanZheng on GitHub. Read the source before you install it.

Installation

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

1

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.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. 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.
2

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/JinFanZheng/kode-sdk-csharp.git /tmp/kode-sdk-csharp
mkdir -p .claude/skills
cp -r /tmp/kode-sdk-csharp/examples/Kode.Agent.WebApiAssistant/skills/fx .claude/skills/fx
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Fx 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 Fx 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 Fx 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.

FX skill（汇率：口径先对齐，再给数字）

心智模型

  • “汇率”不是一个数字：可能是市场现价（mid/bid/ask）、官方中间价/参考价、银行现汇/现钞买卖价，口径不同数字就不同。
  • 默认口径：用户没说清楚时，默认给 市场现价 mid（中间价），但要明确写出来。
  • 时间敏感：带“今天/最新/实时/现在”时，必须写来源页面的当地更新时间；拿不到就写“来源未标注”。

只问 1 个关键问题（仅在必要时）

如果用户没有说清楚口径，只问一次：

  • “你要看 市场现价（默认 mid）还是 官方/银行牌价？”

如果用户说“换算/兑换”，还缺金额时只问一个：

  • “你要换算多少金额？按哪种口径（市场现价/银行牌价）？”

输出硬要求（强约束）

必须包含：

  • 货币对（如 USD/CNY）
  • 口径（市场 mid / bid/ask；或 官方中间价；或 银行现汇/现钞）
  • 来源 + 链接
  • 当地时间（来源页面的更新时间/发布时间；拿不到就写“来源未标注”）

建议格式（Markdown）：

  • USD/CNY 市场现价（mid）：X.XXXX（来源：xxx；当地时间：YYYY-MM-DD HH:mm / 来源未标注）
    • 备注：口径说明（可选）

来源策略（中国为主，混合：白名单 + 全网补证）

白名单（用于下结论）

官方口径

  • pbc.gov.cn（中国人民银行相关公告/数据）
  • cfets.org.cn（中国外汇交易中心相关发布）

银行牌价（现汇/现钞）

  • 银行官网牌价页面（例如 boc.cn 等；以用户指定银行为准）

全网（仅作补证/交叉验证）

  • 大型行情/财经数据平台可用于“市场现价”线索，但必须清楚标注来源与更新时间；不要把单一来源当作“官方口径”。

NEVER（绝对禁止）

  • 不要编造任何汇率数字、来源链接、更新时间
  • 不要把不同口径混在一起（例如把“银行现钞卖出价”当“市场中间价”）
  • 不要暗示“这是官方价”但引用的却是第三方平台

Frequently asked questions

What does the Fx AI skill do?

Exchange rates / FX lookup workflow. Use for currency exchange rate questions (USD/CNY, EUR/CNY, etc.), “today/latest/real-time” rates, conversion requests, or when you need to cite FX numbers. Default to market mid rate unless user asks for official/bank rates. Must include source link + local update time; NEVER fabricate.

Why use Fx on TypingMind?

Because you install it once and use it with any model. Fx 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.

How do I install Fx in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/JinFanZheng/kode-sdk-csharp/tree/main/examples/Kode.Agent.WebApiAssistant/skills/fx. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Fx?

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.

How many AI models can I use with Fx?

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

Is the Fx AI skill free?

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

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.

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.
