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 | $0.00075 | $0.02723 |
| Opus 5 | $0.00037 | $0.01362 |
| Sonnet 5 | $0.00015 | $0.00545 |
| Haiku 4.5 | $0.00007 | $0.00272 |
Grade B, and why
active-directory-attacks scanned grade B 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 2d 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.
Harvests environment variablesmediumData exfiltration
Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.
Extract credentials directly from DC (requires Replicating Directory Changes rights): Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Asks for rootlowPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
sudo date -s "14 APR 2024 18:25:16" Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Active Directory Attacks
Purpose
Provide comprehensive techniques for attacking Microsoft Active Directory environments. Covers reconnaissance, credential harvesting, Kerberos attacks, lateral movement, privilege escalation, and domain dominance for red team operations and penetration testing.
Inputs/Prerequisites
- Kali Linux or Windows attack platform
- Domain user credentials (for most attacks)
- Network access to Domain Controller
- Tools: Impacket, Mimikatz, BloodHound, Rubeus, CrackMapExec
Outputs/Deliverables
- Domain enumeration data
- Extracted credentials and hashes
- Kerberos tickets for impersonation
- Domain Administrator access
- Persistent access mechanisms
Essential Tools
| Tool | Purpose |
|---|---|
| BloodHound | AD attack path visualization |
| Impacket | Python AD attack tools |
| Mimikatz | Credential extraction |
| Rubeus | Kerberos attacks |
| CrackMapExec | Network exploitation |
| PowerView | AD enumeration |
| Responder | LLMNR/NBT-NS poisoning |
Core Workflow
Step 1: Kerberos Clock Sync
Kerberos requires clock synchronization (±5 minutes):
# Detect clock skew
nmap -sT 10.10.10.10 -p445 --script smb2-time
# Fix clock on Linux
sudo date -s "14 APR 2024 18:25:16"
# Fix clock on Windows
net time /domain /set
# Fake clock without changing system time
faketime -f '+8h' <command>
Step 2: AD Reconnaissance with BloodHound
# Start BloodHound
neo4j console
bloodhound --no-sandbox
# Collect data with SharpHound
.\SharpHound.exe -c All
.\SharpHound.exe -c All --ldapusername user --ldappassword pass
# Python collector (from Linux)
bloodhound-python -u 'user' -p 'password' -d domain.local -ns 10.10.10.10 -c all
Step 3: PowerView Enumeration
# Get domain info
Get-NetDomain
Get-DomainSID
Get-NetDomainController
# Enumerate users
Get-NetUser
Get-NetUser -SamAccountName targetuser
Get-UserProperty -Properties pwdlastset
# Enumerate groups
Get-NetGroupMember -GroupName "Domain Admins"
Get-DomainGroup -Identity "Domain Admins" | Select-Object -ExpandProperty Member
# Find local admin access
Find-LocalAdminAccess -Verbose
# User hunting
Invoke-UserHunter
Invoke-UserHunter -Stealth
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.

active-directory-attacks is a skill published in the GitHub repository zebbern/claude-code-guide (4,597 stars, last pushed yesterday), licensed MIT. It adds 75 tokens to every session and 2,723 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 2 findings (harvests environment variables, asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
