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 | $0.00097 | $0.02261 |
| Opus 5 | $0.00048 | $0.01130 |
| Sonnet 5 | $0.00019 | $0.00452 |
| Haiku 4.5 | $0.00010 | $0.00226 |
Grade C, and why
configuring-host-based-intrusion-detection scanned grade C 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 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.

Configuring Host-Based Intrusion Detection
When to Use
Use this skill when:
- Deploying HIDS agents (Wazuh, OSSEC, AIDE) across Windows and Linux endpoints
- Configuring file integrity monitoring (FIM) for compliance (PCI DSS 11.5, NIST SI-7)
- Monitoring system configuration changes, rootkit detection, and security policy violations
- Integrating HIDS alerts with SIEM platforms for centralized monitoring
Do not use this skill for network-based IDS (Suricata, Snort) or for EDR deployment.
Prerequisites
- Wazuh server (manager) deployed and accessible from endpoints
- Administrative access to target endpoints
- Network connectivity: agents to Wazuh manager on port 1514 (TCP/UDP) and 1515 (TCP enrollment)
- Wazuh dashboard (OpenSearch Dashboards) for alert visualization
- Understanding of critical files/directories to monitor per OS
Workflow
Step 1: Install Wazuh Agent
Windows:
# Download and install Wazuh agent
Invoke-WebRequest -Uri "https://packages.wazuh.com/4.x/windows/wazuh-agent-4.9.0-1.msi" `
-OutFile "wazuh-agent.msi"
msiexec /i wazuh-agent.msi /q WAZUH_MANAGER="wazuh-manager.corp.com" `
WAZUH_REGISTRATION_SERVER="wazuh-manager.corp.com" WAZUH_AGENT_GROUP="windows-workstations"
net start WazuhSvc
Linux (Debian/Ubuntu):
curl -s https://packages.wazuh.com/key/GPG-KEY-WAZUH | gpg --dearmor -o /usr/share/keyrings/wazuh.gpg
echo "deb [signed-by=/usr/share/keyrings/wazuh.gpg] https://packages.wazuh.com/4.x/apt/ stable main" \
> /etc/apt/sources.list.d/wazuh.list
apt-get update && apt-get install wazuh-agent -y
sed -i 's/MANAGER_IP/wazuh-manager.corp.com/' /var/ossec/etc/ossec.conf
systemctl daemon-reload && systemctl enable --now wazuh-agent
Step 2: Configure File Integrity Monitoring (FIM)
Edit agent configuration (/var/ossec/etc/ossec.conf or C:\Program Files (x86)\ossec-agent\ossec.conf):
<syscheck>
<!-- Scan frequency: every 12 hours -->
<frequency>43200</frequency>
<scan_on_start>yes</scan_on_start>
<alert_new_files>yes</alert_new_files>
<!-- Linux critical directories -->
<directories check_all="yes" realtime="yes">/etc</directories>
<directories check_all="yes" realtime="yes">/usr/bin</directories>
<directories check_all="yes" realtime="yes">/usr/sbin</directories>
<directories check_all="yes" realtime="yes">/bin</directories>
<directories check_all="yes" realtime="yes">/sbin</directories>
<directories check_all="yes">/boot</directories>
<!-- Windows critical directories -->
<directories check_all="yes" realtime="yes">C:\Windows\System32</directories>
<directories check_all="yes" realtime="yes">C:\Windows\SysWOW64</directories>
<directories check_all="yes" realtime="yes">%PROGRAMFILES%</directories>
<!-- Windows registry monitoring -->
<windows_registry>HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run</windows_registry>
<windows_registry>HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce</windows_registry>
<windows_registry>HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services</windows_registry>
<!-- Ignore frequently changing files -->
<ignore>/etc/mtab</ignore>
<ignore>/etc/resolv.conf</ignore>
<ignore type="sregex">.log$</ignore>
</syscheck>
What ships with it
7 files 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.

configuring-host-based-intrusion-detection is a skill published in the GitHub repository 26zl/cybersec-toolkit (54 stars, last pushed yesterday), licensed MIT. It adds 97 tokens to every session and 2,261 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it C with 2 findings (hidden instructions, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
