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 | $0.00638 | $0.00638 |
| Opus 5 | $0.00319 | $0.00319 |
| Sonnet 5 | $0.00128 | $0.00128 |
| Haiku 4.5 | $0.00064 | $0.00064 |
Grade A, and why
weatherlink-mcp 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 6d 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
copilot-rules.md ― Weatherlink‑MCP 専用・最小ガイドライン
目的
Copilot の提案を「MCP サーバー開発（Python + FastAPI）に最適化」し、読みやすく安全なコードを保つ。
1. 言語・記法
- 実装: Python 3.11 ／ 型注釈必須
- 命名: 説明的な英語（snake_case）
- コメント／テスト名／README: 日本語
- インデント 4 スペース
2. 実装スタイル
| 項目 | ルール |
|---|---|
| アーキテクチャ | FastAPI + mcp-python。ディレクトリはapp/ (FastAPI)・domain/ (純粋ロジック)・tests/ |
| 関数型志向 | 可能な限り純粋関数。副作用関数は _io 接尾辞で区別 |
| 契約(DbC) | docstring に‐ 事前条件 Pre:‐ 事後条件 Post:を記述し、assert で検証 |
| 関数長 | 20 行以下・サイクロマティック複雑度 ≤ 7 |
| 早期 return | ネストを浅く保つ |
3. TDD ワークフロー
- RED: pytest で失敗テストを書く
- GREEN: 最小実装で通す
- REFACTOR: 重複削除・命名整理
- コミット:
feat: …,refactor: …等 Conventional Commits
4. ドキュメント & 自動化
README.mdを必ず更新（概要／起動方法／.env 設定）- CI:
pytest,ruff,mypyを GitHub Actions で実行 .env*・キャッシュ・ビルド物は.gitignore
5. セキュリティ
- API キーを絶対にハードコードしない
- 外部入力は
pydanticでバリデーション - 例外は具体的なメッセージ付きで
HTTPException
6. 禁止事項
- 未使用インポート／デバッグ
print - 無意味なコメントや TODO 放置
- main ブランチへの直接 push

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.
- 6d ago First seen · 53 lines · 638 tokens per session scan A 57df11894429
weatherlink-mcp copilot-instructions.md is an instructions file published in the GitHub repository tomohiroJin/weatherlink-mcp (0 stars, last pushed 1y ago), licensed MIT. It adds 638 tokens to every session, about $0.0032 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.
