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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00037 | $0.00484 |
| Opus 5 | $0.00018 | $0.00242 |
| Sonnet 5 | $0.00007 | $0.00097 |
| Haiku 4.5 | $0.00004 | $0.00048 |
Grade A, and why
reading-notion 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 11d 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
Reading Notion
NotionページやドキュメントをMarkdownに変換して読み取り、内容を要約・説明するスキルです。
概要
このスキルは2つのモードで動作します：
- URL直接モード: Notion URLが会話に登場した時、
notion-to-mdを使って自動的にMarkdownに変換し、内容を説明 - 検索モード: キーワードでNotionを検索し、結果から選択したページの内容を説明
URL直接モードでは、Go製のCLIツールnotion-to-mdを使用してNotion APIからページデータを取得し、Markdown形式に変換します。これにより、ネスト構造、豊富なブロックタイプ、テキストアノテーションなどを正確に保持したMarkdownファイルが生成されます。
モード詳細
URL直接モード
Notion URLを検出すると自動的に発動します。詳細は reference/url-mode.md を参照してください。
発動例:
- ユーザーが
https://www.notion.so/myorg/abc123def456ghi789jkl012mno34567のようなURLを提示 - 会話中にNotion URLが登場
検索モード
キーワードでNotion内を検索したい時に発動します。詳細は reference/search-mode.md を参照してください。
発動例:
- 「データ基盤チームについて教えて」
- 「Notionでプロジェクト〇〇を検索して」
- 特定のキーワードに関する情報を求められた時
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
