Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

pre-send-check-3point 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

/pre-send-check-3point

オーナー送信前 3 点セルフチェック。オーナーへの送付・配置・提案の直前に、頭の中で通す 3 点チェック。ファイル I/O なし・ログなし・5 秒で済ませる。

背景:チャット添付の文字化け・ファイル階層の深すぎ・直前すぎるリマインドなど、送信前チェック習慣の欠如による「やり直し」を減らすためのもの。

3 点チェック

1. デバイス/視野で開けるか

  • チャットのスマホビューでそのまま読めるか(.md 添付や生 Markdown 記法でなく、プレーンテキストで成立しているか)
  • 添付ファイルの形式はオーナーの環境で開けるか
  • ファイル基盤に置くなら階層は浅いか(深い階層に埋めない)

2. 分量・粒度が適正か

  • オーナーが集中を切らさず受け取れる長さか
  • 選択肢を出すなら整理されて絞られているか(内部用語はベタな説明に展開)
  • 同じ内容を二度言っていないか

3. 次の意思決定を即できる粒度か

  • 「どれにしますか」「OK/NG」のように即答可能な形になっているか
  • リマインド・提案ならタイミングは適切か(直前過ぎないか)
  • オーナーに考えさせる残り物がないか(エージェント側で判断できることを混ぜていないか)

発火タイミング

オーナーに届く副作用を持つツール呼び出しの直前に内省的に通す:

  • チャット reply(通常返信・draft 配信・リマインド)
  • ファイル基盤へのファイル作成・配置
  • カレンダー登録・変更
  • メール draft 作成

やらないこと

  • チェック結果のログ・記録(軽量重視。効果は「やり直し」回数の減少で観測する)
  • 内部書き込み(diary/observations/エージェント間 inbox/ログ類)への適用 — オーナーに届かないものは対象外
  • 真の緊急アラートでのチェック優先 — 速度が勝つ場面では飛ばしてよい

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.
