使用 nerva 进行高性能服务指纹识别。当需要识别开放端口的具体服务时使用。nerva 支持 120+ 协议（数据库、远程访问、消息队列、工控、Web 等），是 fingerprintx 的升级版。任何涉及服务识别、协议探测、端口指纹的场景都应使用此技能
- Works in 3 steps: 基本使用 → 扫描模式 → 管道集成
- SKILL.md covers Phase 1: 基本使用, Phase 2: 扫描模式 and Phase 3: 管道集成
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Nerva Scan is an agent skill from wgpsec/AboutSecurity. 使用 nerva 进行高性能服务指纹识别。当需要识别开放端口的具体服务时使用。nerva 支持 120+ 协议（数据库、远程访问、消息队列、工控、Web 等），是 fingerprintx 的升级版。任何涉及服务识别、协议探测、端口指纹的场景都应使用此技能
Its SKILL.md is about 270 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Everything for pentest. | 渗透测试知识库，以 AI Agent 可执行的格式沉淀安全方法论。
Example prompts
- “/nerva-scan”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- 基本使用
- 扫描模式
- 管道集成
What it can do on your machine
Read from SKILL.md and the folder at commit d428372. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
github.com
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
Nerva Scan loads about 265 tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 21 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.

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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 21 words (~265 tokens).
