+- 🔸 数据目录 (`~/.gitlink/`)
+- 🔸 配置文件 (`~/.config/gitlink-cli/`)
+- 🔸 npm全局包 (`@gitlink-ai/cli`)
+
+### 保留文件
+- 📌 用户的项目文件
+- 📌 Git仓库
+- 📌 系统环境变量（需手动清理）
+
+---
+
+## 🧹 清理剩余文件
+
+### Linux/macOS
+
+```bash
+# 检查剩余文件
+find ~ -name "*gitlink*" -type f 2>/dev/null
+find ~ -name "*gitlink*" -type d 2>/dev/null
+
+# 清理环境变量（如果手动添加过）
+# 编辑 ~/.bashrc, ~/.zshrc 等，删除相关行
+```
+
+### Windows
+
+```powershell
+# 检查剩余文件
+Get-ChildItem -Path $env:USERPROFILE -Recurse -Filter "*gitlink*" -ErrorAction SilentlyContinue
+
+# 清理PATH环境变量
+# 1. 打开"系统属性" > "环境变量"
+# 2. 在"用户变量"或"系统变量"的Path中删除gitlink-cli路径
+```
+
+---
+
+## ❓ 常见问题
+
+### Q1: 卸载后命令仍然可用？
+
+**A**: 可能是PATH缓存问题，解决方法：
+
+**Linux/macOS**:
+```bash
+# 刷新shell
+hash -r gitlink-cli
+
+# 或重启终端
+```
+
+**Windows**:
+```powershell
+# 重启PowerShell或CMD
+```
+
+### Q2: 提示权限不足？
+
+**A**: 使用管理员权限或删除到用户目录：
+
+**Linux/macOS**:
+```bash
+# 使用sudo
+sudo bash uninstall.sh
+
+# 或安装到用户目录
+INSTALL_DIR=$HOME/.local/bin bash uninstall.sh
+```
+
+**Windows**:
+```powershell
+# 以管理员身份运行PowerShell
+```
+
+### Q3: 如何重新安装？
+
+**A**: 重新运行安装脚本即可：
+
+```bash
+# Linux/macOS
+curl -sSL https://www.gitlink.org.cn/Gitlink/gitlink-cli/raw/master/install.sh | bash
+
+# Windows
+powershell -NoProfile -ExecutionPolicy Bypass -File install.ps1
+
+# npm
+npm install -g @gitlink-ai/cli
+```
+
+### Q4: 配置文件会自动删除吗？
+
+**A**: 不会，除非使用 `--purge` 参数或确认删除。这是为了保护用户数据。
+
+### Q5: Skills会被删除吗？
+
+**A**: 会的，Skills目录会被自动删除。如需保留，请手动备份：
+
+```bash
+# 备份Skills
+cp -r ~/.gitlink/skills ~/gitlink-skills-backup
+```
+
+---
+
+## 🔍 故障排除
+
+### 卸载脚本找不到
+
+```bash
+# 确保在项目目录中
+cd /path/to/gitlink-cli
+
+# 检查脚本是否存在
+ls -la uninstall.sh uninstall.ps1
+```
+
+### 删除失败
+
+```bash
+# 检查文件权限
+ls -la /usr/local/bin/gitlink-cli
+
+# 强制删除
+sudo rm -f /usr/local/bin/gitlink-cli
+```
+
+### npm卸载后仍有残留
+
+```bash
+# 手动清理npm缓存
+npm cache clean --force
+
+# 检查全局安装位置
+npm root -g
+npm list -g --depth=0
+
+# 手动删除残留
+```

+## ✅ 卸载检查清单
+
+完成卸载后，可以检查以下内容：
+
+- [ ] 命令不可用（运行 `gitlink-cli --version` 应该报错）
+- [ ] 二进制文件已删除
+- [ ] Skills目录已删除
+- [ ] 配置文件已删除（如需要）
+- [ ] PATH环境变量已清理
+- [ ] 没有残留进程（`ps aux | grep gitlink` 或任务管理器）
