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 5.1 | $0.00087 | $0.03180 |
| Opus 5 | $0.00044 | $0.01590 |
| Sonnet 5 | $0.00017 | $0.00636 |
| Haiku 4.5 | $0.00009 | $0.00318 |
Grade B, and why
network-attack 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 7d 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.

Network Attack & Lateral Movement
When to Activate
- Internal network pentest from an unauthenticated wire position or initial foothold
- Layer-2/3 poisoning to capture credentials (LLMNR/NBT-NS/mDNS, ARP/DHCP, IPv6 mitm6)
- Coercion + NTLM relay from the network (signing/EPA mapping, CVE-2025-33073 reflection)
- Pivoting / tunneling across segments (Ligolo-ng, Chisel, SSH, DNS tunneling)
- Traffic interception / MitM (bettercap, RDP/SSH/STARTTLS downgrade, cookie theft)
- Network-service exploitation (SMB/RDP/RDL/NEGOEX RCE, MSSQL/WinRM/LDAP abuse)
- Wireless assessment (WPA2 capture/crack, WPA3-Transition downgrade, evil-twin 802.1X)
- For AD-specific relay targets (LDAP RBCD/shadow-creds, ADCS ESC8, Kerberos relay) and
ticket/DCSync work, hand off to
active-directory-attack.

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.
- 7d ago First seen · 129 lines · 87 tokens per session scan B 03c62565365c
network-attack is a skill published in the GitHub repository hypnguyen1209/offensive-claude (355 stars, last pushed 20d ago), licensed MIT. It adds 87 tokens to every session and 3,180 once invoked, about $0.0004 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.
