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 | $0.00065 | $0.00788 |
| Opus 5 | $0.00032 | $0.00394 |
| Sonnet 5 | $0.00013 | $0.00158 |
| Haiku 4.5 | $0.00006 | $0.00079 |
Grade A, and why
ics-ot 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 7d 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
94% identical to ics-ot-overview — 2 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.
How it starts
The opening of the file, as written. The whole thing — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Industrial Control Systems / OT Category
This is a routing skill for industrial protocol engagements. Identify the protocol by port + wire format, then load the matching sub-skill.
SAFETY FIRST
Writes to ICS/OT devices can move physical actuators — open valves, trip breakers, freeze pumps, override safety setpoints. Confirm written scope authorization for any write/control class operation. Read-only enumeration is generally safe. If unsure, default to read-only.
Protocol routing
| Protocol | TCP/UDP Port | Sub-skill | Wire fingerprint |
|---|---|---|---|
| Modbus TCP | TCP 502 | modbus |
MBAP header, function codes 1-127 |
| BACnet/IP | UDP 47808 | bacnet |
APDU PDU types 0-15, Who-Is/I-Am |
| Siemens S7Comm | TCP 102 | s7comm |
ISO-on-TCP (RFC 1006) + S7 protocol IDs |
| DNP3 | TCP 20000 | dnp3 |
Start bytes 0x05 0x64, link layer |
| EtherNet/IP + CIP | TCP 44818, UDP 2222 | (use enumeration; CVE-driven exploits) | ENIP encapsulation header |
| PROFINET RT | UDP 34962-34964 | (use enumeration) | EtherType 0x8892 (L2) |
| OPC UA | TCP 4840 | (use enumeration) | OPC UA Binary protocol |

Defender baseline (useful for triage)
ICS-CERT advisories (https://www.cisa.gov/uscert/ics/advisories), Dragos Threat Intel Briefs, Nozomi / Claroty / Tenable.ot for telemetry. Understanding what defenders see helps you stay below detection thresholds.
What ships with it
4 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.

ics-ot is a skill published in the GitHub repository MingyiSecLab/Mingyi-Atlas (11 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 65 tokens to every session and 788 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 94% identical to ics-ot-overview, differing in 2 lines, and is treated as a copy.
