What this skill tells the agent
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 --hardgit clean -f/git clean -fdgit branch -Dgit 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):
{
"hooks": {
"PreToolUse": [
{
"matcher": "Bash",
"hooks": [
{
"type": "command",
"command": "\"$CLAUDE_PROJECT_DIR\"/.claude/hooks/block-dangerous-git.sh"
}
]
}
]
}
}Global (~/.claude/settings.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:
echo '{"tool_input":{"command":"git push origin main"}}' | <path-to-script>应以 code 2 退出,并向 stderr 打印 BLOCKED message。
