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 | $0.00057 | $0.02029 |
| Opus 5 | $0.00028 | $0.01014 |
| Sonnet 5 | $0.00011 | $0.00406 |
| Haiku 4.5 | $0.00006 | $0.00203 |
Grade A, and why
network-101 scanned grade A 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.
Asks for rootlowPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
sudo apt update && sudo apt install apache2 Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

Network 101
Purpose
Configure and test common network services (HTTP, HTTPS, SNMP, SMB) for penetration testing lab environments. Enable hands-on practice with service enumeration, log analysis, and security testing against properly configured target systems.
Inputs/Prerequisites
- Windows Server or Linux system for hosting services
- Kali Linux or similar for testing
- Administrative access to target system
- Basic networking knowledge (IP addressing, ports)
- Firewall access for port configuration
Outputs/Deliverables
- Configured HTTP/HTTPS web server
- SNMP service with accessible communities
- SMB file shares with various permission levels
- Captured logs for analysis
- Documented enumeration results
Core Workflow
1. Configure HTTP Server (Port 80)
Set up a basic HTTP web server for testing:
Windows IIS Setup:
- Open IIS Manager (Internet Information Services)
- Right-click Sites → Add Website
- Configure site name and physical path
- Bind to IP address and port 80
Linux Apache Setup:
# Install Apache
sudo apt update && sudo apt install apache2
# Start service
sudo systemctl start apache2
sudo systemctl enable apache2
# Create test page
echo "<html><body><h1>Test Page</h1></body></html>" | sudo tee /var/www/html/index.html
# Verify service
curl http://localhost
Configure Firewall for HTTP:
# Linux (UFW)
sudo ufw allow 80/tcp
# Windows PowerShell
New-NetFirewallRule -DisplayName "HTTP" -Direction Inbound -Protocol TCP -LocalPort 80 -Action Allow
2. Configure HTTPS Server (Port 443)
Set up secure HTTPS with SSL/TLS:
Generate Self-Signed Certificate:
# Linux - Generate certificate
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 \
-keyout /etc/ssl/private/apache-selfsigned.key \
-out /etc/ssl/certs/apache-selfsigned.crt
# Enable SSL module
sudo a2enmod ssl
sudo systemctl restart apache2
Configure Apache for HTTPS:
# Edit SSL virtual host
sudo nano /etc/apache2/sites-available/default-ssl.conf
# Enable site
sudo a2ensite default-ssl
sudo systemctl reload apache2
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.

network-101 is a skill published in the GitHub repository zebbern/claude-code-guide (4,597 stars, last pushed yesterday), licensed MIT. It adds 57 tokens to every session and 2,029 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
