Scanning Network With Nmap Advanced is an agent skill from mukul975/Anthropic-Cybersecurity-Skills. Performs advanced network recon using Nmap's Scripting Engine (NSE), timing controls, firewall/IDS evasion, and structured output parsing to discover hosts, enumerate service versions, detect vulnerabilities, and fingerprint OSes. Use during authorized penetration tests or enterprise asset-discovery assessments needing scan evasion, NSE vulnerability checks, or output fed into a vulnerability management pipeline.
Its SKILL.md is about 2.3k 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/api-reference.md` and `scripts/agent.py`).
It sits in Security, covering Penetration testing, Vulnerability scanning and Structured output and tool calling. It works with Nmap. The repository describes itself as: 817 structured cybersecurity skills for AI agents · Mapped to 6 frameworks: MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, D3FEND, NIST AI RMF & MITRE F3 (Fight Fraud) · agentskills.io…. The licence is Apache-2.0.
6 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 54a7988. It shows what the files ask for, not the result of running them.
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.
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
mysqlFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Scanning Network With Nmap Advanced loads about 2.3k tokens when it runs, and up to ~2.8k if it reads all its reference files. Until then it costs about 113 tokens; SKILL.md has 621 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.
The automated check found no risky patterns in SKILL.md.
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.

|---|---|
| SYN Scan (-sS) | Half-open TCP scan that sends SYN packets and analyzes responses without completing the three-way handshake, making it faster and stealthier than connect scans |
| NSE (Nmap Scripting Engine) | Lua-based scripting framework built into Nmap that enables vulnerability detection, brute forcing, service discovery, and custom automation |
| Timing Templates (-T0 to -T5) | Predefined scan speed profiles ranging from Paranoid (T0) to Insane (T5), controlling probe parallelism, timeout values, and inter-probe delays |
| Idle Scan (-sI) | Advanced scan technique that uses a zombie host's IP ID sequence to port scan a target without sending packets from the scanner's own IP address |
| Version Intensity | Controls how many probes Nmap sends to determine service versions, ranging from 0 (light) to 9 (all probes), trading speed for accuracy |
| Grepable Output (-oG) | Legacy Nmap output format designed for easy parsing with grep, awk, and sed for scripted analysis of scan results |
Context: A security team needs to establish a vulnerability baseline for a corporate network spanning 10.0.0.0/8 with approximately 5,000 active hosts. Scanning must complete within a weekend maintenance window with minimal network disruption.
Approach:
--min-rate 5000 and -T4 to complete within the windowPitfalls:
--min-rate too high on congested network segments causing packet loss and false negatives-T5 (Insane) timing on production networks, potentially overwhelming older network devices-oX or -oA), losing structured data for downstream tool integration## Nmap Scan Summary
**Scan Profile**: Full TCP + Top 200 UDP + Service Enumeration
**Target Range**: 10.10.0.0/16
**Hosts Discovered**: 347 live hosts
**Scan Duration**: 2h 14m

|------|------|---------|---------|---------------|
| 10.10.5.23 | 445/tcp | SMB | Windows Server 2012 R2 | MS17-010 (EternalBlue) |
| 10.10.8.100 | 443/tcp | Apache httpd | 2.4.29 | CVE-2021-41773 (Path Traversal) |

| 10.10.3.77 | 161/udp | SNMP | v2c | Public community string |
### Recommendations
1. Patch MS17-010 on 10.10.5.23 immediately -- Critical RCE vulnerability
2. Upgrade Apache httpd to 2.4.58+ on 10.10.8.100
3. Upgrade MySQL to 8.0.x on 10.10.12.5 and restrict bind address
4. Change SNMP community strings from "public" on 10.10.3.77© mukul975, Apache-2.0. Rendered from Markdown: HTML in the file is shown as text, images as links, and headings moved down two levels. Raw file

Going by SKILL.md and its folder, Scanning Network With Nmap Advanced needs Python for the scripts in its folder and the command-line tools its instructions call (mysql). Our summary lists: Python 3.
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.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. 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.
Scanning Network With Nmap Advanced is published under the Apache-2.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.3k tokens (SKILL.md is roughly 9.2k 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 519 tokens, read only when the agent opens those files.
