Install with your agent

Agent handoff

Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.

  1. Download the package from Yavira.
  2. Extract it into a folder your agent can access.
  3. Paste one of the prompts below and point your agent at the extracted folder.
New install

I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.

Upgrade existing

I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

Nmap Recon

Network reconnaissance and port scanning using Nmap. Use when asked to scan a target, find open ports, detect services, check for vulnerabilities, or perform network reconnaissance.

Triggers

"scan [target]", "port scan", "nmap", "what ports are open", "recon [target]", "service detection", "vulnerability scan"

Requirements

nmap must be installed (standard on Kali, available via package managers) Root/sudo for SYN scans and OS detection

Quick Scan (Top 1000 ports)

nmap -sC -sV -oA scan_$(date +%Y%m%d_%H%M%S) TARGET

Full Port Scan

nmap -p- -sC -sV -oA fullscan_$(date +%Y%m%d_%H%M%S) TARGET

Fast Scan (Quick check)

nmap -F -T4 TARGET

Stealth SYN Scan (requires root)

sudo nmap -sS -sV -O -oA stealth_$(date +%Y%m%d_%H%M%S) TARGET

UDP Scan (Top 100 ports)

sudo nmap -sU --top-ports 100 -oA udp_$(date +%Y%m%d_%H%M%S) TARGET

Vulnerability Scan

nmap --script vuln -oA vulnscan_$(date +%Y%m%d_%H%M%S) TARGET

Aggressive Scan (OS, version, scripts, traceroute)

nmap -A -T4 -oA aggressive_$(date +%Y%m%d_%H%M%S) TARGET

Output Parsing

Nmap outputs in multiple formats with -oA: .nmap - Human readable .xml - Machine parseable .gnmap - Greppable format

Parse open ports from greppable output:

grep "open" scan.gnmap | awk -F'[/]' '{print $1}' | tr ',' '\n' | sort -u

Extract service versions:

grep -E "^[0-9]+/" scan.nmap | awk '{print $1, $3, $4}'

Quick summary from XML:

xmllint --xpath "//port[@state='open']" scan.xml 2>/dev/null

Script Categories

# List available scripts ls /usr/share/nmap/scripts/ # Run specific category nmap --script=default,safe TARGET nmap --script=vuln TARGET nmap --script=exploit TARGET nmap --script=auth TARGET # Run specific script nmap --script=http-title TARGET nmap --script=smb-vuln* TARGET

Target Specification

# Single host nmap 192.168.1.1 # CIDR range nmap 192.168.1.0/24 # Range nmap 192.168.1.1-254 # From file nmap -iL targets.txt # Exclude hosts nmap 192.168.1.0/24 --exclude 192.168.1.1

Timing Templates

-T0 Paranoid (IDS evasion) -T1 Sneaky (IDS evasion) -T2 Polite (slow) -T3 Normal (default) -T4 Aggressive (fast) -T5 Insane (very fast, may miss ports)

Authorization Required

โš ๏ธ Only scan targets you own or have explicit written authorization to test. Never scan: Public infrastructure without permission Networks you don't control Production systems without approval

Example Workflow

# 1. Quick scan to find live hosts nmap -sn 192.168.1.0/24 -oA live_hosts # 2. Fast port scan on discovered hosts nmap -F -T4 -iL live_hosts.gnmap -oA quick_ports # 3. Deep scan interesting hosts nmap -p- -sC -sV -oA deep_scan TARGET # 4. Vulnerability scan nmap --script vuln -oA vuln_scan TARGET
