  • 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.

  • 3 bundled files

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

  • Open source

    Published by cas-bigdatalab on GitHub. Read the source before you install it.

Installation

Install the Fullwidth Halfwidth Normalizer 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/cas-bigdatalab/piflow/tree/master/workspace/skills/fullwidth_halfwidth_normalizer
  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/cas-bigdatalab/piflow.git /tmp/piflow
mkdir -p .claude/skills
cp -r /tmp/piflow/workspace/skills/fullwidth_halfwidth_normalizer .claude/skills/fullwidth_halfwidth_normalizer
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Fullwidth Halfwidth Normalizer 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 Fullwidth Halfwidth Normalizer 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 Fullwidth Halfwidth Normalizer 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.

fullwidth_halfwidth_normalizer 全角半角规范化Skill

功能概述

将文本中的全角 ASCII 字符(U+FF01-U+FF5E、U+3000)转换为半角形式,并支持可选的 Unicode 正规化处理。覆盖字母、数字、标点符号的全半角统一,中文专属标点(。、【】、《》等)不受影响。

触发条件

  • 全角转半角
  • 半角规范化
  • 全半角统一
  • 全角字母/数字/标点转换
  • Unicode 正规化
  • 中日韩混排文本清洗

输入文件格式

  • CSV (.csv) / TSV (.tsv) / Excel (.xls, .xlsx) / SPSS (.sav)

使用方法

步骤1:获取用户输入输出路径

向用户确认:

  1. 输入文件路径(需要处理的文件)
  2. 输出文件路径(处理后的文件)
  3. 可选:指定处理的文本列
  4. 可选:Unicode正规化形式

步骤2:执行全角半角规范化脚本

在 scripts/ 目录下找到 fullwidth_halfwidth_normalizer.py,使用Python执行:

基本用法:

bash
python scripts/fullwidth_halfwidth_normalizer.py \
    --input_path <输入文件> \
    --output_path <输出文件>

带可选参数:

bash
python scripts/fullwidth_halfwidth_normalizer.py \
    --input_path <输入文件> \
    --output_path <输出文件> \
    --text_columns col1,col2 \
    --norm_form NFKC \
    --keep_newlines

步骤3:返回结果

脚本执行完成后,告知用户全角字符转换数量和输出文件路径。

核心参数说明

必需参数

参数说明
--input_path输入结构化文件路径
--output_path输出规范化后文件路径

可选参数

--text_columns 指定规范化列,其他参数控制转换方向和字符范围。

参数说明

参数必填说明
--input_path是输入文件路径
--output_path是输出文件路径
--text_columns否处理的文本列,逗号分隔
--norm_form否NFC/NFD/NFKC/NFKD
--keep_newlines否保留换行符

输出示例

[OK] 全角/半角规范化完成 -> output.csv
   文本列: ['text']
   norm_form=无, keep_newlines=False

输入 2024年,AI技术 → 输出 2024年,AI技术

环境要求

使用项目 Python 环境运行,依赖 pandas 和共享 data_io 读写工具。

注意事项

  1. 仅转换 U+FF01-U+FF5E 范围内的全角 ASCII 字符和 U+3000 全角空格
  2. 中文专属标点(。、【】、《》、——等)不受影响
  3. NFKC 正规化会一并处理全角字符和其他兼容字符
  4. 默认折叠换行为空格,使用 --keep_newlines 可保留

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 Fullwidth Halfwidth Normalizer AI skill do?

全角/半角字符规范化工具。读取结构化数据文件,将文本中的全角ASCII字符(字母、数字、标点)转换为半角形式, 并可按需执行指定 Unicode 正规化。适用于中日韩混排科研文本的统一预处理,不负责空白行删除、拼写纠错或重复标点合并。 当用户提到全角转半角、半角规范化、全半角统一、全角字母数字转换等需求时使用此skill。

Why use Fullwidth Halfwidth Normalizer on TypingMind?

Because you install it once and use it with any model. Fullwidth Halfwidth Normalizer 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 Fullwidth Halfwidth Normalizer in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/cas-bigdatalab/piflow/tree/master/workspace/skills/fullwidth_halfwidth_normalizer. 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 Fullwidth Halfwidth Normalizer?

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 Fullwidth Halfwidth Normalizer?

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

Is the Fullwidth Halfwidth Normalizer AI skill free?

It is published on GitHub by cas-bigdatalab. Check the repository for licensing terms. 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.
