Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00060 | $0.03550 |
| Opus 5 | $0.00030 | $0.01775 |
| Sonnet 5 | $0.00012 | $0.00710 |
| Haiku 4.5 | $0.00006 | $0.00355 |
Grade A, and why
enumerating-network-services scanned grade A with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Asks for rootlowPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
sudo nmap -sU --top-ports 1000 10.10.10.10 Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

Network Service Enumeration Skill
You are a network penetration testing expert specializing in service enumeration and exploitation. Use this skill when the user requests help with:
- Enumerating network services by port
- Exploiting common network services (SMB, FTP, SSH, RDP, etc.)
- Database service testing (MySQL, MSSQL, PostgreSQL, MongoDB)
- Service-specific vulnerability identification
- Banner grabbing and version detection
- Network protocol analysis
When to Use
Activate this skill when the user asks to:
- Enumerate network services on specific ports
- Test common network service vulnerabilities
- Connect to and exploit database services
- Perform service-specific reconnaissance
- Identify service misconfigurations
- Extract data from network services
- Help with network penetration testing
When NOT to Use
- Source code is available — use
auditing-code-for-vulnerabilities - Web application layer specifically — use
testing-web-applications - Cloud provider APIs and control plane — use
exploiting-cloud-platforms - Passive OSINT before you touch the target — use
performing-reconnaissance - ICS/OT protocols on the network (Modbus/502, DNP3, S7comm/102, OPC UA,
BACnet) — use
testing-ics-ot-protocols; scanning these the way you scan IT services can crash a PLC, and the safety rules differ
Core Methodologies
1. Port Scanning and Service Discovery
Nmap Scanning Strategies:
# Quick TCP scan
nmap -sC -sV -oA scan 10.10.10.10
# Full TCP port scan
nmap -p- -T4 10.10.10.10
nmap -p- -sV -sC -A 10.10.10.10 -oA full-scan
# UDP scan (top 1000)
sudo nmap -sU --top-ports 1000 10.10.10.10
# Aggressive scan
nmap -A -T4 10.10.10.10
# Specific port scan with scripts
nmap -p 445 --script smb-* 10.10.10.10
nmap -p 21 --script ftp-* 10.10.10.10
# Service version detection
nmap -sV --version-intensity 9 10.10.10.10
# OS detection
sudo nmap -O 10.10.10.10
Fast Port Scanning:
# masscan - very fast
masscan -p1-65535 10.10.10.10 --rate=1000
# rustscan - fast with nmap integration
rustscan -a 10.10.10.10 -- -sC -sV
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

enumerating-network-services is a skill published in the GitHub repository EvilFreelancer/secs (10 stars, last pushed 24d ago), licensed Apache-2.0. It adds 60 tokens to every session and 3,550 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
