Token cost

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.

Security

Grade A, and why

04-operation 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 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.

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.

Origin

This is a copy

86% identical to 01-collection — 25 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.

What it actually says

Codex adapter: AI-PLC Stage 4

実行前に Codex実行環境の読み替えを読む。正本の手順・入力・モードは実行時に読み込み、以下は環境差分として適用する。

  1. リポジトリルートの .claude/skills/ai-plc/04-operation/SKILL.md を最後まで読み、その手順を正本として実行する。
  2. .claude/rules/ai-plc-system.md、.claude/rules/ai-plc-session.md、.claude/rules/ai-plc-adaptive.md を最後まで読む。
  3. Knowledge Lintでは .claude/skills/ai-plc/04-operation/knowledge-lint.md、Platform Builderでは同階層の platform-builder.md を読む。
  4. DB、Wiki、Rules、Templatesは正本に記載された .claude/ 配下を使用する。
  5. Claude CodeのAgent toolやスラッシュコマンド表記は、利用可能なCodexのsub-agentまたは対応スキル指定へ置き換える。
  6. 正本のPhase 5.5の発動強度(必須・既定・省略可)を判定する。対象になる「独立検証(maker≠checker)」は、Codexのsub-agent起動を明示的に要求する適用中の指示として扱う。対象タスクではユーザーへ再確認せず、成果物作成者とは別のsub-agent reviewerを自動起動する。
  7. backlog(または Agent 定義)のdelegable: falseはPhase 4の成果物作成を並列委譲しないという意味であり、Phase 5.5の独立reviewer起動を禁止しない。
  8. 独立レビュー対象でのセルフ検証へのフォールバックは、sub-agent機能が利用不能、起動失敗、またはreviewer出力を取得できない場合に限る。フォールバック時は理由をVerification recordへ1行記録する。

正本が見つからない場合はタスク実行やbacklog.yaml更新を行わず、欠落パスを報告して停止する。

モデルの既定: .claude/rules/ai-plc-model-routing.md の「実行環境の既定」に従う。本人のモデル指定が無ければ Operation は Claude Code(Opus)へ切り替える案内を出して止まり、本人が Codex での実行を明示したときだけ続行する。

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.
