  • 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.

  • 4 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

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

Installation

Install the Et Excel 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.
    https://github.com/FlameskyDexive/Legends-Of-Heroes/tree/master/Packages/cn.etetet.harness/skills/et-excel
  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.

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/FlameskyDexive/Legends-Of-Heroes.git /tmp/Legends-Of-Heroes
mkdir -p .claude/skills
cp -r /tmp/Legends-Of-Heroes/Packages/cn.etetet.harness/skills/et-excel .claude/skills/et-excel
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Et Excel 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 Et Excel 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 Et Excel 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.

et-excel - ET Excel 入口

强制规则（重要）

  • 只要涉及 Excel/xlsx 的任何读写操作，都必须调用 excelmcp（ET.ExcelMcp）完成；禁止手写脚本或用其它库/工具直接改 xlsx。

  • excelmcp 源工程位置：./Packages/cn.etetet.config/DotNet~/ET.ExcelMcp。

  • 运行入口（编译产物）：仓库根目录 ./Bin/ET.ExcelMcp.dll，统一在仓库根用 dotnet ./Bin/ET.ExcelMcp.dll ... 调用。

  • 若 ./Bin/ET.ExcelMcp.dll 不存在（没有可执行文件），先编译工程再操作：

    powershell
    dotnet build "./Packages/cn.etetet.config/DotNet~/ET.ExcelMcp/ET.ExcelMcp.csproj" -c Debug

    产物会输出到 ./Bin/ET.ExcelMcp.dll（csproj 的 OutputPath = $(RepoRoot)Bin，RepoRoot 即仓库根）。

何时使用

  • 通过 Bin/ET.ExcelMcp.dll 读写 Excel
  • 处理单元格、区域、样式、公式、图表、工作表
  • 做批量数据导入导出、筛选、排序、合并单元格
  • 维护 Luban 配置表内容，但还没有进入导出阶段

不要加载

  • 只是编译、跑测试、做 Unity 编辑器操作
  • 只是执行 Luban 导出，不需要实际读写 Excel（用 et-luban）
  • 只是讨论表结构，不需要实际读写 Excel

默认动作

  1. 先 cli list 或 cli help <工具名>，不要硬背完整工具表。
  2. 能批量就批量，优先 excel_range / excel_data_operations，不要逐格操作。
  3. JSON 参数只传本次调用最小字段集；pwsh 中优先外层单引号。
  4. 写操作优先使用绝对路径；覆盖原文件前先确认目标文件。
  5. 维护 Luban __beans__/__enums__/多态数据表时：用 excel_data_operations batch_write 只写非空格（空行真空）；写完必须 excel_merge_cells merge 合并"列表"表头（*fields J1:P1、*items H1:L1、多态字段表头跨子列宽），否则 Luban 导出报缺 alias 列；含中文走 Write→UTF-8 Python→ExcelMcp，读回校验合并用 get_merged、文本用 ascii()。完整格式见 et-luban。
  6. 改完表如果需要生成配置产物，再叠加 et-luban。

配置约定（项目规范）

  • 资源类字段只填资源名：不写完整路径与后缀；表里若出现 Assets/.../xxx.prefab 这类完整路径，应收敛为 xxx（加载侧按名字 LoadAsset）。
  • 新增配置表必须注册 __tables__.xlsx：补全 Category / value_type / input / index / group，否则 Luban 导不到这张表。
  • 改完表必须导出，且优先定向导出：只导受影响的配置数据/代码（如对应 GameConfig 的 s / c / cs），避免全量导出超时；导出与导出后 Unity 刷新走 et-luban。
  • 写中文必须二次验证：读回或检查 xlsx 的 sharedStrings.xml，不要只信终端输出（详见 references/et-excel-cli.md 的「中文写入防乱码」）。

优先入口

  • dotnet ./Bin/ET.ExcelMcp.dll cli list
  • dotnet ./Bin/ET.ExcelMcp.dll cli help <工具名>
  • dotnet ./Bin/ET.ExcelMcp.dll cli <工具名> '<JSON参数>'

按需补读

  • references/et-excel-cli.md：工具选择、pwsh JSON 传参、常用示例

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Et Excel AI skill do?

ET Excel MCP workflow for reading, writing, styling, transforming, and inspecting xlsx data. Use when operating Excel cells, ranges, sheets, formulas, charts, merges, batch data import/export, or editing Luban source spreadsheets before export.

Why use Et Excel on TypingMind?

Because you install it once and use it with any model. Et Excel 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 Et Excel in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/FlameskyDexive/Legends-Of-Heroes/tree/master/Packages/cn.etetet.harness/skills/et-excel. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Et Excel?

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 Et Excel?

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

Is the Et Excel AI skill free?

Yes. It is published on GitHub by FlameskyDexive 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.
