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 | $0.00066 | $0.00345 |
| Opus 5.5 | $0.00026 | $0.00138 |
| Sonnet 5.5 | $0.00013 | $0.00069 |
| Haiku 4.5 | $0.00007 | $0.00034 |
Grade A, and why
plc-model-routing 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.
What it actually says
Codex adapter: plc-model-routing
- Codex実行環境の読み替え とリポジトリルートの
.claude/skills/plc-model-routing/SKILL.md、そこで指定する共通ruleを読む。手順と完了条件は正本を使う。 - 共通CLIのTask選択では
--environment codexを使い、現在のtool schema/CLI helpで実在するmodel/推論強度を確認して渡す。モデルoverrideのあるspawn_agentはfull-history forkを使わず、Taskと必要入力を明示する。担当/Advisorの成果物作成委譲は明示承認の範囲に従う。 - 現行exec JSONからserved-model IDが取得できなければactual_model=null/未確認を残す。requested model、設定、自己申告から補完しない。親チャットを自動切替済みとは報告しない。
--recordで保存CLI記録を正規化できる。 - Advisorと独立reviewerを分ける。04-operationとBT checkerの契約は正本のまま維持する。
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.

plc-model-routing is a skill published in the GitHub repository miyatti777/ai-plc (49 stars, last pushed 2d ago), licensed MIT. It adds 66 tokens to every session and 345 once invoked, about $0.0003 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 2026-10-23.
