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 | $0.05883 | $0.05883 |
| Opus 5 | $0.02942 | $0.02942 |
| Sonnet 5 | $0.01177 | $0.01177 |
| Haiku 4.5 | $0.00588 | $0.00588 |
Grade A, and why
slack-utils-channel CLAUDE.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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 780 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude Rules for slack-utils
このドキュメントはClaude/Cursor AIがslack-utilsプロジェクトで作業する際のルールとガイドラインを定義します。
📋 プロジェクト概要
slack-utils は Slack Deno SDK v2.x を使用したSlackアプリケーション開発テンプレートです。
- 言語: TypeScript (Deno v2互換)
- 主な用途: Slack Functions、Workflows、Triggersの管理
- デプロイ: Slack CLI を使用
- ライセンス: MIT

🔍 コードベース検索・調査のルール
必須ツールの使用
このプロジェクトでは以下のツールを必ず使用してください:
1. Serena - リポジトリ内コード検索
プロジェクト内のコード検索にはserenaを使用:
// ✅ 正しい使用例
mcp_serena_find_symbol({
name_path: "functionName",
relative_path: "functions/",
});
mcp_serena_search_for_pattern({
substring_pattern: "エラーパターン",
relative_path: "lib/",
});
使用するシーン:
- 関数やクラスの定義を探す
- 特定のパターンやキーワードを検索
- プロジェクト構造の理解
- シンボルの参照箇所を調べる
2. Context7 - モジュール・ライブラリ調査
外部モジュールやライブラリの調査にはcontext7を使用:
// ✅ 正しい使用例
// まずライブラリIDを解決
mcp_Context7_resolve - library - id({
libraryName: "deno slack sdk",
});
// 次にドキュメントを取得
mcp_Context7_get - library - docs({
context7CompatibleLibraryID: "/slackapi/deno-slack-sdk",
topic: "functions",
});
主要ライブラリ:
/slackapi/deno-slack-sdk- Slack Deno SDK/denoland/deno- Deno runtime/websites/deno- Deno公式ドキュメント
💻 技術スタック
Deno (v2.x)
- 公式ドキュメント:
/websites/deno - セキュアなランタイム
- TypeScript標準サポート
- 組み込みテストランナー
Slack Deno SDK (v2.15.1+)
- ライブラリID:
/slackapi/deno-slack-sdk - Slack Functions、Workflows、Triggersをサポート
- 最新のSlack Platform featuresに対応
📝 コーディング規約
TypeScript
- Strictモード必須:
deno.jsoncでstrict: trueを設定 - 暗黙的なanyを禁止: 全ての型を明示的に定義
- JSDocコメント必須: 全ての公開関数に追加
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.
- 8d ago First seen · 780 lines · 5,883 tokens per session scan A 5a8dd79ba7b1
slack-utils-channel CLAUDE.md is an instructions file published in the GitHub repository leaveanest/slack-utils-channel (4 stars, last pushed 2mo ago), licensed MIT. It adds 5,883 tokens to every session, about $0.0294 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.
