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.
2 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by vinvcn on GitHub. Read the source before you install it.

Installation

Install the Git Guardrails Claude Code 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.
Enable the skill in any chat where you want it available.

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/vinvcn/mattpocock-skills-zh-CN.git /tmp/mattpocock-skills-zh-CN
mkdir -p .claude/skills
cp -r /tmp/mattpocock-skills-zh-CN/skills/misc/git-guardrails-claude-code .claude/skills/git-guardrails-claude-code

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

Use it in TypingMind

Enable Git Guardrails Claude Code 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 Git Guardrails Claude Code 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 Git Guardrails Claude Code 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.

Setup Git Guardrails

设置一个 PreToolUse hook，在 Claude 执行危险 git commands 前拦截并阻止它们。

What Gets Blocked

git push（包括 --force 在内的所有 variants）
git reset --hard
git clean -f / git clean -fd
git branch -D
git checkout . / git restore .

被阻止时，Claude 会看到一条 message，说明它无权访问这些 commands。

Steps

1. Ask scope

询问用户：只为当前 project 安装（.claude/settings.json），还是为所有 projects 安装（~/.claude/settings.json）？

2. Copy the hook script

bundled script 位于：scripts/block-dangerous-git.sh

根据 scope 复制到目标位置：

Project: .claude/hooks/block-dangerous-git.sh
Global: ~/.claude/hooks/block-dangerous-git.sh

用 chmod +x 让它可执行。

3. Add hook to settings

添加到对应 settings file：

Project (.claude/settings.json):

json
{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "Bash",
        "hooks": [
          {
            "type": "command",
            "command": "\"$CLAUDE_PROJECT_DIR\"/.claude/hooks/block-dangerous-git.sh"
          }
        ]
      }
    ]
  }
}

Global (~/.claude/settings.json):

json
{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "Bash",
        "hooks": [
          {
            "type": "command",
            "command": "~/.claude/hooks/block-dangerous-git.sh"
          }
        ]
      }
    ]
  }
}

如果 settings file 已存在，把 hook merge 到现有 hooks.PreToolUse array 中，不要覆盖其他 settings。

4. Ask about customization

询问用户是否要在 blocked list 中添加或移除 patterns。相应编辑复制后的 script。

5. Verify

运行快速测试：

bash
echo '{"tool_input":{"command":"git push origin main"}}' | <path-to-script>

应以 code 2 退出，并向 stderr 打印 BLOCKED message。

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 Git Guardrails Claude Code AI skill do?

Why use Git Guardrails Claude Code on TypingMind?

Because you install it once and use it with any model. Git Guardrails Claude Code 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 Git Guardrails Claude Code in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/vinvcn/mattpocock-skills-zh-CN/tree/main/skills/misc/git-guardrails-claude-code. 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 Git Guardrails Claude Code?

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 Git Guardrails Claude Code?

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

Is the Git Guardrails Claude Code AI skill free?

Yes. It is published on GitHub by vinvcn 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.
