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 | $0.00337 | $0.00337 |
| Opus 5.5 | $0.00135 | $0.00135 |
| Sonnet 5.5 | $0.00067 | $0.00067 |
| Haiku 4.5 | $0.00034 | $0.00034 |
Grade A, and why
interactive-markdown-table-editor copilot-instructions.md 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 26d 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
## 基本原則
- 応答は日本語で丁寧な口調で行なうこと
- タスクを指示された場合は、コードの修正に入る前に、修正方針を簡潔に述べること
- 原因が特定できていないまま推測で修正してはならない。問題の根本原因を特定し、修正内容がその原因に対処していることを確認すること
- 静的なコードの分析だけでは原因の特定が困難な場合は、ログを出力して動作確認を依頼してから、ログの情報をもとに原因を特定すること
- 実装するコードやログ、メッセージに 🔍, ❌, ✅ などの絵文字を含めないこと
テストに関するルール
- プロダクトコードに変更を加えた場合は、必ずテストを実行すること
- 変更内容に関係のないテストの失敗であっても、自身の責務によらず修正を行うこと
- テストの失敗を放置することは、すなわちプロダクト品質低下に繋がる重大な問題である
- テストカバレッジは100%を維持し、100%を下回る場合はテストコードを追加してカバレッジを100%にすること
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.
