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.

What it costs to keep this loaded
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 | $0.00061 | $0.01294 |
| Opus 5 | $0.00030 | $0.00647 |
| Sonnet 5 | $0.00012 | $0.00259 |
| Haiku 4.5 | $0.00006 | $0.00129 |
Grade A, and why
nmap-network-scan 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.

Network Scanning with nmap
How to Call the nmap MCP Tools
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" TOOL_NAME '{"param":"value"}'
When to Use
- Discover what hosts are alive on a subnet before deeper analysis
- Find open ports on network devices, servers, or lab infrastructure
- Verify firewall rules by checking which ports are reachable
- Pre-change/post-change port scans to confirm expected service exposure
- Asset discovery on RFC1918 or lab networks
Available Tools
| Tool | Purpose | Privileges |
|---|---|---|
nmap_ping_scan |
ICMP+TCP host discovery (no port scan) | none |
nmap_arp_discovery |
ARP host discovery (LAN only) | cap_net_raw |
nmap_top_ports |
Fast scan of N most common ports | none |
nmap_syn_scan |
SYN half-open port scan (fast, stealthy) | cap_net_raw |
nmap_tcp_scan |
Full TCP connect scan (no root needed) | none |
nmap_udp_scan |
UDP port scan (DNS, SNMP, NTP, etc.) | cap_net_raw |
Workflow: Subnet Discovery
When asked "what's on this network?" or "scan this subnet":
Step 1: Host Discovery
Find live hosts first — avoids wasting time port-scanning dead IPs.
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_ping_scan '{"target":"192.168.1.0/24"}'
On directly-connected LANs, ARP discovery is more reliable:
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_arp_discovery '{"target":"192.168.1.0/24"}'
Step 2: Quick Port Scan
Scan the top 100 common ports on discovered hosts:
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_top_ports '{"target":"192.168.1.1","count":100}'
Step 3: Targeted Port Scan
For deeper scanning, use SYN scan (faster) or TCP connect scan:
# SYN scan — faster, requires cap_net_raw
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_syn_scan '{"target":"192.168.1.1","ports":"1-65535"}'
# TCP connect — works without special privileges
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_tcp_scan '{"target":"192.168.1.1","ports":"22,80,443,8080"}'
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.

nmap-network-scan is a skill published in the GitHub repository automateyournetwork/netclaw (657 stars, last pushed 6d ago), licensed Apache-2.0. It adds 61 tokens to every session and 1,294 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
