File utility toolkit for searching, analyzing, and comparing files. Find files by pattern/size/date, count lines, get file statistics, and compare file contents. Use when working with file discovery, analysis, or comparison tasks.
JSON processing toolkit for validating, formatting, querying, and comparing JSON data. Use when working with JSON files, API responses, configuration files, or any structured JSON data that needs parsing, validation, transformation, or comparison.
Perform network reconnaissance including host discovery, port scanning, and service enumeration. Use when asked to "scan a network", "find hosts", "discover devices", "enumerate services", "recon a subnet", or "what's on my network".
This skill should be used when the user asks to "run pentest commands", "scan with nmap", "use metasploit exploits", "crack passwords with hydra or john", "scan web vulnerabilities with nikto", "enumerate networks", or needs essential penetration testing command references.

A toolkit for diagnosing network connectivity issues and verifying host/service availability.
Activate this skill when the user needs to:
Always run scripts with --help first to see all available options.
| Script | Purpose |
|---|---|
ping_host.py | Ping a host to check reachability |
check_port.py | Check if a TCP port is open |
dns_lookup.py | Perform DNS lookups |
Task → What do you need to check?
│
├─ Is the host reachable at all?
│ └─ Use: ping_host.py <hostname>
│
├─ Is a specific service/port available?
│ └─ Use: check_port.py <hostname> <port>
│
└─ Need to resolve a domain name?
└─ Use: dns_lookup.py <domain>
Check if a host is reachable:
python scripts/ping_host.py google.com
python scripts/ping_host.py 8.8.8.8 --count 5
Check if a port is open:
python scripts/check_port.py example.com 443
python scripts/check_port.py localhost 8080 --timeout 5
DNS lookup:
python scripts/dns_lookup.py example.com
python scripts/dns_lookup.py example.com --type MX
check_port.py myserver.com 80check_port.py server.local 22check_port.py db.example.com 5432dns_lookup.py problematic-domain.com
