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 | $0.00058 | $0.02455 |
| Opus 5 | $0.00029 | $0.01228 |
| Sonnet 5 | $0.00012 | $0.00491 |
| Haiku 4.5 | $0.00006 | $0.00246 |
Grade A, and why
ntlm-relay-coercion scanned grade A with 0 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 8d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to ntlm-relay-coercion — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

SKILL: NTLM Relay and Authentication Coercion — Expert Attack Playbook
AI LOAD INSTRUCTION: Expert NTLM relay and coercion techniques. Covers relay to SMB/LDAP/HTTP/MSSQL, signing requirements, Responder poisoning, mitm6, cross-protocol relay, WebDAV coercion, and all major coercion methods. Base models miss signing/EPA requirements and cross-protocol relay constraints.

NTLMv1 vs NTLMv2
| Feature | NTLMv1 | NTLMv2 |
|---|---|---|
| Security | Weak (crackable to NTLM hash) | Stronger (but still relayable) |
| Relay | Yes | Yes |
| Crack to hash | Yes (rainbow tables, crack.sh) | Offline brute-force only |
| Downgrade | Force via Responder --lm |

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.

ntlm-relay-coercion is a skill published in the GitHub repository DorianGallo/hack-skills-local (5 stars, last pushed 3mo ago), licensed MIT. It adds 58 tokens to every session and 2,455 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to ntlm-relay-coercion, differing in 0 lines, and is treated as a copy.
