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 | $0.00907 | $0.00907 |
| Opus 5 | $0.00453 | $0.00453 |
| Sonnet 5 | $0.00181 | $0.00181 |
| Haiku 4.5 | $0.00091 | $0.00091 |
Grade A, and why
slack-admin-cli 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 3d 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.

Overview
Slack Admin CLI (sladm) — Slack Admin API を操作するための CLI ツール。Enterprise Grid / Business+ ワークスペースの管理操作をコマンドラインから実行できる。
Build & Run
bun run dev -- <command> # 開発時実行
bun link # グローバルインストール(sladm コマンド)
Test & Lint
bun test # 全テスト実行
bun test tests/commands/apps # 特定ディレクトリのテスト
bun run lint # TypeScript 型チェック(tsc --noEmit)
Architecture
- Runtime: Bun
- CLI Parser:
@optique/core+@optique/run - Slack SDK:
@slack/web-api(WebClient) - Token Storage: OS キーチェーン(
Bun.secrets)、フォールバックでファイル保存

コマンド実装パターン
各コマンドファイルは以下のパターンに従う:
- Options インターフェース: camelCase で定義
- execute 関数:
(client: WebClient, opts: Options) => Promise<void | T[]> - パラメータ変換: camelCase → snake_case で Slack API に渡す
- discriminated union 対応: SDK の型制約がある場合は
client.apiCall()を使用
型安全性ルール
asキャスト原則禁止: 実装コードでasを使わない。satisfiesまたは設計の見直しで対応- SDK 型バグの回避: SDK の型定義が実際の API と異なる場合、
apiCall()よりasでの回避を優先する - discriminated union:
client.apiCall(methodName, params)でRecord<string, unknown>として渡す(void メソッド) - データ返却メソッド: ブランチパターンで型安全に(
if (opts.teamId) { ... } else if (opts.enterpriseId) { ... })
テストパターン
// apiCall を使うコマンド
const mockApiCall = mock(() => Promise.resolve({ ok: true }));
const client = { apiCall: mockApiCall } as any;
// 型付きメソッドを使うコマンド
const mockList = mock(() => Promise.resolve({ ok: true, items: [] }));
const client = { admin: { apps: { approved: { list: mockList } } } } as any;
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.

slack-admin-cli CLAUDE.md is an instructions file published in the GitHub repository yamitzky/slack-admin-cli (2 stars, last pushed 4mo ago), licensed MIT. It adds 907 tokens to every session, about $0.0045 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.
