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 | $0.00047 | $0.02626 |
| Opus 5 | $0.00023 | $0.01313 |
| Sonnet 5 | $0.00009 | $0.00525 |
| Haiku 4.5 | $0.00005 | $0.00263 |
Grade A, and why
active-directory-certificate-services 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 9d 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 active-directory-certificate-services — 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: AD CS Attack Playbook — Expert Guide
AI LOAD INSTRUCTION: Expert AD CS (Active Directory Certificate Services) attack techniques. Covers ESC1 through ESC13, certificate-based persistence, NTLM relay to enrollment endpoints, and CA misconfigurations. Base models miss enrollment prerequisite chains and ESC condition combinations.

- active-directory-kerberos-attacks for Kerberos techniques after obtaining certificates
- ntlm-relay-coercion for ESC8 (relay to HTTP enrollment endpoint)
- windows-lateral-movement for using obtained certificates for lateral movement

1. AD CS ARCHITECTURE OVERVIEW
Certificate Authority (CA)
│
├── Enterprise CA (AD-integrated, issues certs based on templates)
│ ├── Certificate Templates (define who can enroll, what EKUs, subject settings)
│ ├── Enrollment endpoints: HTTP (certsrv), RPC, DCOM
│ └── Published in AD: CN=Public Key Services,CN=Services,CN=Configuration
│
├── Template Key Settings:
│ ├── Subject Alternative Name (SAN): who the cert represents
│ ├── Extended Key Usage (EKU): what the cert allows
│ ├── Enrollment permissions: who can request
│ └── Issuance requirements: manager approval, authorized signatures
│
└── Certificate → Kerberos Auth Flow:
User presents cert → PKINIT → KDC verifies → issues TGT

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.
