What it does
Masscan Scan is an agent skill from wgpsec/AboutSecurity. 使用 masscan 进行超大规模高速端口扫描。当需要扫描大范围 CIDR 网段、全互联网规模扫描时使用。masscan 是异步无状态扫描器，速度可达每秒百万包级别，适合大规模资产发现。需要 root 权限。任何涉及大规模网段扫描、高速端口发现、互联网测绘的场景都应使用此技能
Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Security. It works with Nmap. 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。
When your agent uses it
- Security work in your project
Example prompts
- “/masscan-scan”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- 基本扫描
- 大规模扫描
- 输出格式
- 高级选项
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
Masscan Scan loads about 523 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 79 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 79 words (~523 tokens).
