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 | $0.00044 | $0.00618 |
| Opus 5.5 | $0.00018 | $0.00247 |
| Sonnet 5.5 | $0.00009 | $0.00124 |
| Haiku 4.5 | $0.00004 | $0.00062 |
Grade A, and why
plc-status-audit 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 18d 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.
What it actually says
Codex adapter: AI-PLC Status Audit
このadapterはCodex固有の入口だけを提供し、処理本文は.claude互換runtimeの正本を使う。
前提確認（変更前に必須）
repository root基準で、次の4ファイルがregular fileとして存在し読めることを確認する。
.claude/skills/plc-status-audit/SKILL.md.claude/rules/ai-plc-system.md.claude/rules/ai-plc-session.md.claude/rules/ai-plc-adaptive.md
1件でも欠落・読取不能なら、DB、Layer ファイルその他の状態を変更せず、欠落pathを列挙して停止する。
実行
- 必須3 Rulesを上記順で最後まで読む。
- 正本
.claude/skills/plc-status-audit/SKILL.mdを最後まで読む。 - コマンドとデータは正本に記載されたパスを使用する。
--briefはread-only確認として実行できる。--quietはレポート（report.md / report.json）の書き出しだけを行う。--apply … --yesはユーザーが承認した承認ファイルに対してだけ実行する。--jevは外部送信を伴うため明示されたときだけ使う。- Claude Code固有のAgent toolまたは起動表記が現れた場合は、許可されたCodex sub-agentまたは対応する
$skill-nameへ変換する。 - 正本のClaude Code native memory参照を
~/.claudeへ解決してはならない。Codexでは読取・更新とも行わず、該当処理は変更なし — スキップ（Codex adapter: Claude native memory非対象）と記録する。
Read-only diagnostics
ユーザーがAI-PLC prerequisite diagnosticsを明示した場合は正本の処理を実行せず、変更0で停止する。正本Skillと必須3 Rulesの4件ごとにabsolute_path、sha256、最初のH1、末尾のversion行をprerequisite_diagnosticsとして返す。4件のいずれかが欠落・読取不能ならstatus: blockedと対象pathを返す。Rules 3件は併せてrule_diagnosticsとして識別できるようにする。
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.
- 18d ago First seen · 33 lines · 44 tokens per session scan A d4720d88afe8
plc-status-audit is a skill published in the GitHub repository miyatti777/ai-plc (49 stars, last pushed 17d ago), licensed MIT. It adds 44 tokens to every session and 618 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-30.
