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 | $0.00342 | $0.04013 |
| Opus 5 | $0.00171 | $0.02006 |
| Sonnet 5 | $0.00068 | $0.00803 |
| Haiku 4.5 | $0.00034 | $0.00401 |
Grade A, and why
melsec-iqr-simple-cpu-comm-csv 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 10d 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.
How it starts

MELSEC iQ-R シンプルCPU通信 設定CSV ジェネレータ
このSkillは、MELSEC iQ-RシリーズCPUユニットの シンプルCPU通信機能 (内蔵Ethernetポート部)の設定を、GX Works3 と完全互換の CSVファイル として生成・検証・逆解析する。
出典: MELSEC iQ-R Ethernetユーザーズマニュアル(応用編) 1.15節 (p.220-242)。
このSkillの守備範囲
| 扱う | 扱わない |
|---|---|
| シンプルCPU通信設定 (1.15節) のCSV生成・検証・解析 | 他のEthernet通信機能(MELSOFT接続、SLMP通信、ソケット通信、CC-Link IEFB Basic等) |
| 機器種別 16/17/18/19/20/22/23/25/26/30 の交信相手対応 | 安全CPU通信(RnSF/RnPSF)の安全デバイス通信 |
ヘッダー部 (ファイルバージョン/対象ユニット/自局IPアドレス/IPアドレス入力形式/デバイス割付方法/通信開始待ち時間/初回交信設定) |
自局CPU の Ethernet 自ノード設定/二重化設定(自ノード設定/B系IPアドレス等は別途設定) |
| 設定No.1~64 の各カラム(通信パターン/交信設定/実行間隔/IP/ポート/対象号機/ビット・ワードデバイス/タイムアウト/リトライ/異常監視時間/コメント) | リモートパスワード設定/セキュリティ設定 |
| デバイス種別の機器種別ごとの可否・範囲(PDF p.224-228 完全反映) | エンジニアリングツールGUIの操作手順 |
| ビット先頭16倍数チェック・1設定512ワード上限・全体8192ワード上限 | エラーコードCFB4H 等の異常応答コード解析(マニュアル参照) |
⚠️ iQ-Rプロジェクトの固定制約(重要)
GX Works3 のシンプルCPU通信設定画面で iQ-Rプロジェクト時に 編集不可(グレーアウト) な項目があり、それらに値を入れた CSV をインポートすると GX Works3 が該当行を破棄してデフォルト値の空行に置き換える。本スクリプトはこれらを違反した時点でバリデーションエラーで停止する。
| 項目 | iQ-R での値 | 備考 |
|---|---|---|
IPアドレス入力形式 (header.ip_format) |
"DEC" 固定 |
10進数のみ。HEX は GUI で選択不可 |
オプション(16進数) (settings[].target.option_hex) |
"" 固定 |
GUI で編集不可。SLMP 含めて全機器種別で空欄必須 |
これは MELSEC iQ-R Ethernetマニュアル本文には明記されていない、GX Works3 GUI実装上の制約。 他CPU(QnUDV等)では HEX 指定可能と推測されるが、本スキルは iQ-R 専用 のため上記を強制する。
根本原則
- GX Works3 が出力する CSV と完全バイト一致 を目標とする ── UTF-16LE+BOM/タブ区切り/CRLF/全セル
"..."囲み。手書きで編集して壊さないこと。 - 生成前に必ず
validateで検証する ── デバイス番号・点数・ポート規則・パターン制約は機器種別ごとに異なり、エラーがあると GX Works3 がインポートを拒否する。 - このスキルはCSV専用 ── ユニットパラメータ書込みやCPUリセット等の実機操作は別途エンジニアリングツールで行う必要がある。

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.

melsec-iqr-simple-cpu-comm-csv is a skill published in the GitHub repository mokouliszt/iQRSimpCPUCommSkill (2 stars, last pushed 4mo ago), licensed MIT. It adds 342 tokens to every session and 4,013 once invoked, about $0.0017 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 2026-08-31.
