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 5.1 | $0.00131 | $0.00798 |
| Opus 5 | $0.00066 | $0.00399 |
| Sonnet 5 | $0.00026 | $0.00160 |
| Haiku 4.5 | $0.00013 | $0.00080 |
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

- チーム内に SSOT 仕様書を置く場合は、自分の構成に合わせた場所を参照先にする(例:

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.

pre-send-check-3point is a skill published in the GitHub repository masa-san-jp/Agent-Aiko (3 stars, last pushed 1mo ago), licensed MIT. It adds 131 tokens to every session and 798 once invoked, about $0.0007 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.
