内核参数自动调优。分析系统配置，输出调优建议并可一键应用，支持自动回滚。使用场景：系统性能优化、安全加固、内核参数诊断。
Use when troubleshooting Linux server performance or stability issues — CPU saturation, high load, scheduling delay, memory pressure, OOM events, high RSS, page cache / shared memory growth, memory cgroup residue, Java heap issues, disk IO saturation or latency, packet loss, network jitter, or a server that is slow, stuck, or unstable. Performs diagnosis and surfaces recommendations; does not apply fixes automatically.
Install and configure OpenClaw non-interactively with Alibaba Cloud Model Studio. Use when the user asks to install OpenClaw, configure Aliyun Bailian/Model Studio/DashScope credentials, choose pay-as-you-go, Coding Plan, or Token Plan billing, set Base URL/model config, optionally configure DingTalk, start the local gateway service, or troubleshoot OpenClaw model/auth/channel setup.
Skill 安全状态查看、风险暴露审查、用户决策、快速扫描认证与可选深度扫描。支持用户主动查看或扫描单个/全部 Skill；当用户要求 agent 安装 Skill 且安装成功后，必须自动对最终本地目录执行快速扫描认证。
工作区快照管理。用户说"保存一下"、"存个快照"时创建 checkpoint，仅限 Linux; 说"回滚"、"撤销"、"恢复到之前"时 rollback;说"删掉快照"时 delete; 说"对比快照"、"快照改了什么"时 diff; 说"看看快照"、"有哪些快照"时 list;说"查看快照状态"、"查看快照剩余空间"时 status。
Help users configure, mount, and unmount a skillfs FUSE virtual filesystem on their local machine (e.g. for openclaw). Covers analyzing existing skill usage to suggest view configuration, generating skillfs-views.toml, mounting, and graceful unmount. Use this skill when the user asks to: set up skillfs, configure skill views, mount or unmount skillfs, check if skillfs is running, or get help organizing their skills directory (especially for openclaw users).

Alinux 操作系统内核升级指南。
复制以下清单并跟踪进度：
操作进度：
- [ ] 步骤 1：查看当前的内核版本
- [ ] 步骤 2：检查可用的内核更新
- [ ] 步骤 3：安装/升级内核
- [ ] 步骤 4：升级内核相关组件
- [ ] 步骤 5：更新 GRUB 启动配置
- [ ] 步骤 6：重启系统
确定操作系统类型：
uname -r
sudo yum list available kernel
查看待升级内核相关软件包列表
uname -r
rpm -qa | grep <当前内核版本号>
sudo yum update kernel -y
sudo yum update <待升级内核相关软件包> -y
sudo yum install kernel-<version> -y
sudo yum update <待升级内核相关软件包>-<version> -y
# 列出已安装的内核
sudo grubby --info=ALL | grep ^kernel
# 设置新内核为默认启动项
sudo grubby --set-default /boot/vmlinuz-<new-kernel-version>
# 验证
sudo grubby --default-kernel
sudo reboot
Alibaba Cloud Linux 3.8 版本（镜像日期 20230727~20230925）升级内核时，dracut 会因重复的内核模块配置而报错。该报错不影响内核包安装，但可通过修改 dracut 配置消除。
