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 | $0.00000 | $0.01122 |
| Opus 5.5 | $0.00000 | $0.00449 |
| Sonnet 5.5 | $0.00000 | $0.00224 |
| Haiku 4.5 | $0.00000 | $0.00112 |
Grade A, and why
dev-log 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 1mo 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 — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/dev-log — 開発ログ記録スキル
../Agent-Lab/Agent-team/agents/aiko/dev-docs/dev-log.jsonl への追記と、../Agent-Lab/Agent-team/agents/aiko/dev-docs/ へのドキュメント作成を担います。
自動トリガー(提案)
以下の場面では、このスキルの実行を自動的にユーザーへ提案します:
- ユーザーが作業終了を宣言したとき(「終わり」「以上」「今日はここまで」「お疲れ」など)
- ユーザーが「議事録を作って」「ログを残して」「記録して」と言ったとき
提案内容:
「議事録と dev-log を記録しますか?
1. ../Agent-Lab/Agent-team/agents/aiko/dev-docs/ に議事録ファイルを作成(YYYY-MM-DD-<slug>.md)
2. dev-log.jsonl に本セッションのタスクを追記
両方まとめて行います。よろしければ「はい」とお伝えください。」
モード1: dev-log.jsonl 追記
セッション終了時や作業の節目に実行します。
手順
- 今日の日付を確認(
date +%Y-%m-%d) - 会話の文脈からタスク名・ステータス・サマリーを特定(不明な場合はユーザーに確認)
- 以下のフォーマットで1行末尾に追記:
{"ts":"YYYY-MM-DD","project":"Agent-Aiko","task":"<タスク名>","status":"completed|in_progress|blocked","summary":"実施内容を1〜2文で","issues":[],"decisions":[]}
- 追記内容をユーザーに確認表示する
必須ルール
tsは 今日の日付(YYYY-MM-DD)— 省略・過去日付・未来日付は不可summaryは1〜2文で完結させるissues/decisionsは省略不可(空配列[]でよい)- タスクが複数あれば 1タスク1行 で追記する
モード2: Agent-Lab 側 dev-docs/ へのドキュメント作成
議事録・設計メモ・調査結果などを ../Agent-Lab/Agent-team/agents/aiko/dev-docs/ に新規作成するときに実行します。
ファイル命名規則(必須)
YYYY-MM-DD-<slug>.md
YYYY-MM-DDは 作成日(今日の日付)<slug>はケバブケース(英数字・ハイフンのみ)- 例:
2026-04-29-claude-rule-separation.md
日付プレフィックスは省略不可。 省略されたファイルは受け付けない。
手順
- 今日の日付を確認(
date +%Y-%m-%d) - ファイル名を
YYYY-MM-DD-<slug>.md形式で決定する - ファイルを
../Agent-Lab/Agent-team/agents/aiko/dev-docs/直下に作成する ../Agent-Lab/Agent-team/agents/aiko/dev-docs/README.mdのファイル一覧テーブルに追記するdev-log.jsonlにも1行追記する(モード1のフォーマットで)
議事録の構成(標準テンプレート)
# 議事録:<テーマ>(YYYY-MM-DD)
## 概要
<1〜2文で何をしたか>
## 変更内容
<変更点を箇条書きまたは見出しで>
## 意思決定
<今後の運用に影響する判断・合意事項>
---
*作成日: YYYY-MM-DD*
ドキュメント更新時のリネーム
既存ファイルを大幅に更新した場合は、日付を更新する。git mv は Agent-Lab リポ内で、リポ基準の相対パスで実行する:
cd ../Agent-Lab
git mv Agent-team/agents/aiko/dev-docs/2026-04-27-design.md Agent-team/agents/aiko/dev-docs/2026-05-01-design.md
共通: 完了後の操作
追記・作成後は ../Agent-Lab/ 内で commit & push してください:
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.

dev-log is a skill published in the GitHub repository masa-san-jp/Agent-Aiko (3 stars, last pushed 11d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,122 tokens. 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.
