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 | $0.00247 | $0.01668 |
| Opus 5.5 | $0.00099 | $0.00667 |
| Sonnet 5.5 | $0.00049 | $0.00334 |
| Haiku 4.5 | $0.00025 | $0.00167 |
Grade A, and why
m3e-scratch scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
m3e-scratch
ユーザーの思いつき、アイデア、バグ報告をM3Eマップの scratch ノード配下にプールするスキル。 scratch はタスクの種(seed)置き場 — 後で整理・昇格・削除する前提の気軽な場所。
場所
M:(開発)> SYSTEM > DEV >> scratch
scratch ノードID: n_new_scratch_1775637602039
機能1: ノード追加
1. ユーザー入力を解析
ユーザーの発言から以下を抽出する:
- テキスト: ノードの本文(簡潔に。ユーザーの言葉をなるべくそのまま使う)
- 種別:
idea/bug/memo/taskのいずれか(文脈から判断) - 詳細: 補足があれば
detailsフィールドに入れる - 複数項目: 箇条書きや列挙なら、それぞれ別ノードとして追加
2. マップに書き込む
マップAPIを使う:
- GET
http://localhost:4173/api/mapsでlabel="開発"の mapId を discovery し、対象 map を取得 - 新しいノードを作成:
{ "id": "n_{timestamp}_{random6}", "parentId": "n_new_scratch_1775637602039", "children": [], "nodeType": "text", "text": "ユーザーの入力テキスト", "collapsed": false, "details": "補足情報があれば", "note": "", "attributes": { "kind": "idea|bug|memo|task" }, "link": "" }- カテゴリフォルダが既にあり、そこに入るべき内容なら
parentIdをそのフォルダにする
- カテゴリフォルダが既にあり、そこに入るべき内容なら
- 親ノードの
children配列の末尾に新ノードIDを追加 - POST で全体を書き戻す
- レスポンスの
"ok": trueを確認
3. ID生成
n_{Date.now()}_{Math.random().toString(36).slice(2, 8)}
Bashで生成する場合:
echo "n_$(date +%s%3N)_$(cat /dev/urandom | tr -dc 'a-z0-9' | head -c 6)"
4. ユーザーへの応答
追加したら簡潔に報告:
scratch に追加:
- [idea] レイアウトエンジンにgrid表示モード
- [bug] ノード削除後にalias参照が残る
機能2: scratch 整理
scratch 配下のノードが増えてきたら、カテゴリごとにグルーピングして見通しを良くする。
整理ルール
- 葉ノードは絶対に削除しない — 葉はユーザーのアイデアそのもの。消すのはユーザーだけ
- 整理はフォルダノード(中間ノード)の追加・移動のみで行う
- カテゴリフォルダの例:
UI/UX— 見た目・操作感に関するものデータモデル— ノード構造・属性・型に関するものバグ— 不具合報告インフラ— ビルド・デプロイ・CI/CDアイデア— 大きな構想・将来のビジョン- カテゴリは固定ではない。内容に応じて柔軟に作る
- 1〜2個しかないカテゴリは無理にフォルダを作らない(scratch直下のままでOK)
- 既存のフォルダ構造があればそれを尊重し、追加・調整する
整理の手順
- GET でマップ取得
- scratch 配下の全ノードを走査し、内容を把握
- カテゴリ分けの計画を立てる
- 必要なフォルダノードを作成(
nodeType: "text",attributes: { "role": "category" }) - 葉ノードの
parentIdを適切なフォルダに変更 - 旧親の
childrenから削除、新親のchildrenに追加 - POST で書き戻す
- ユーザーに整理結果を報告:
scratch を整理しました: - UI/UX (3件): grid表示, ダークモード, ツールチップ改善 - バグ (2件): alias参照残り, 折りたたみ状態リセット - 未分類 (1件): ライセンス検討
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.
- 5d ago First seen · 136 lines · 247 tokens per session scan A ee03ba3f3c5d
m3e-scratch is a skill published in the GitHub repository akaghef/M3E (11 stars, last pushed 5d ago), licensed MIT. It adds 247 tokens to every session and 1,668 once invoked, about $0.0010 per session on Opus 5.5. 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 2026-10-02.
