What it does
Network Scanner is an agent skill from ptn1411/skill. Run authorized network reconnaissance with Nmap on Windows (or Linux). Host discovery, port/service/version scanning, OS detection, and safe NSE scripts, parsed into a severity-ranked defensive findings report (exposed services, CVEs from vuln/vulners NSE, weak TLS/SSH, anonymous/default credentials, EOL versions).
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including scripts and reference files (for example `references/nmap_profiles.md`, `scripts/nmap_scan.py` and `scripts/parse_nmap.py`).
It sits in Security, covering Penetration testing and Vulnerability scanning. It works with Nmap and Linux. The repository describes itself as: Bộ công cụ và tập hợp skill hỗ trợ phân tích phần mềm, khôi phục cấu trúc nguồn ở mức cần thiết, rà soát bảo mật, kiểm tra phụ thuộc và xây dựng kế hoạch khắc phục cho các hệ…
When your agent uses it
- Tasks that involve Penetration testing
- Tasks that involve Vulnerability scanning
Example prompts
- “/network-scanner”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Read, Write, Edit, Glob, Grep, Bash
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Authorization & Routing
- Host Discovery (find live hosts)
- Port & Service Scan
- Parse into Findings Report
What it can do on your machine
Read from SKILL.md and the folder at commit ce2b65e. 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:
ReadWriteEditGlobGrepBash
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 2 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
pythonwinget
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):
nmap.org
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
Network Scanner loads about 1.4k tokens when it runs, and up to ~2k if it reads all its reference files. Until then it costs about 83 tokens; SKILL.md has 572 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: Read, Write, Edit, Glob, Grep, Bash
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); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 572 words (~1,437 tokens).

Can I use Network Scanner 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 ptn1411/skill --skill network-scanner -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/network-scanner, .gemini/skills/network-scanner, .github/skills/network-scanner and .opencode/skills/network-scanner in your project.
What does Network Scanner need to run?
Going by SKILL.md and its folder, Network Scanner needs Python for the scripts in its folder and the command-line tools its instructions call (python and winget). Our summary lists: Python 3. Its frontmatter pre-approves these tools: Read, Write, Edit, Glob, Grep, Bash.
Does Network Scanner access the network?
SKILL.md names 1 domain. As links in the text: nmap.org. This is read from the text; nothing was executed.
Is Network Scanner safe to install?
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Network Scanner use?
No licence was found for Network Scanner or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Network Scanner use?
About 1.4k tokens (SKILL.md is roughly 5.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 555 tokens, read only when the agent opens those files.
