What it does
Server Security is an agent skill from majiayu000/spellbook. 服务器安全审计与加固。扫描 SSH、防火墙、端口暴露、文件权限、暴力破解等安全问题，生成报告并提供一键修复。当用户说服务器安全、安全审计、安全检查、安全加固时使用
Its SKILL.md is about 320 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/full-guide.md`).
It sits in Security. The repository describes itself as: Cross-runtime skills for Claude Code, Codex, and multi-agent workflows. The licence is MIT.
When your agent uses it
- Security work in your project
Example prompts
- “/server-security”
Requirements
- Pre-approved tools (allowed-tools): Bash, AskUserQuestion
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Confirm the target, available context, constraints, and done-when signal.
- Read the relevant section of references/full-guide.md for task-specific details.
- Execute the smallest reversible action that satisfies the request.
- Verify with read-only evidence first, then document every applied change with rollback commands and post-change validation.
- Report changed files, commands run, evidence collected, and any remaining risk.
What it can do on your machine
Read from SKILL.md and the folder at commit 6310f81. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
BashAskUserQuestion
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Server Security loads about 324 tokens when it runs, and up to ~3.1k if it reads all its reference files. Until then it costs about 24 tokens; SKILL.md has 139 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Bash, AskUserQuestion
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Server Security Audit
Use this skill for server security audits and reversible hardening plans across SSH, firewall, users, services, file permissions, and update posture.
Routing
- Start here to confirm scope, safety boundaries, and the minimum workflow.
- Load
references/full-guide.mdbefore executing detailed commands, applying templates, or relying on examples from this skill. - Keep the work limited to the user-requested target; do not add adjacent improvements unless the user asks.
Quick Workflow
- Confirm the target, available context, constraints, and done-when signal.
- Read the relevant section of
references/full-guide.mdfor task-specific details. - Execute the smallest reversible action that satisfies the request.
- Verify with read-only evidence first, then document every applied change with rollback commands and post-change validation.
- Report changed files, commands run, evidence collected, and any remaining risk.

Can I use Server Security in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add majiayu000/spellbook --skill server-security -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/server-security, .gemini/skills/server-security, .github/skills/server-security and .opencode/skills/server-security in your project.
What does Server Security need to run?
SKILL.md names no scripts, command-line tools or credentials: Server Security is instructions for the agent only. Its frontmatter pre-approves these tools: Bash, AskUserQuestion.
Does Server Security access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
