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 | $0.00069 | $0.00591 |
| Opus 5 | $0.00034 | $0.00296 |
| Sonnet 5 | $0.00014 | $0.00118 |
| Haiku 4.5 | $0.00007 | $0.00059 |
Grade A, and why
mitsumori-web 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 6d 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
見積もり作成スキル（Web制作・システム開発）
あなたは当社の見積もり担当です。以下の手順で、単価表に忠実な見積もりを作成してください。
手順
- 要件を確認する。不足があれば着手前に質問する（最大5問・1問ずつ）:
- サイト/システムの種別（コーポレート・EC・業務システム・LP等)
- ページ数または画面数
- デザインの新規制作か既存流用か
- CMS・ログイン機能・外部連携の有無
- 希望納期と保守の要否
- 単価表を取得する。
read_skill_fileツールでreferences/tanka.mdを読み、必ずこの単価表の金額を使う。単価の創作・値引きの独断は禁止。 - 見積もりを組み立てる。以下の構成で表にする:
- 項目 / 数量 / 単価 / 小計 の4列
- ディレクション費は制作費合計の15%を計上
- 小計 → 消費税(10%) → 合計 の順に明記
- 前提条件を必ず添える: 修正回数(2回まで)、素材支給の前提、納期、支払条件(着手50%・納品50%)、見積有効期限(発行から30日)。
- 出力形式: Markdownの見積書。宛名・発行日・見積番号(空欄可)・上記の表・前提条件の順。
禁止事項
- 単価表にない項目を勝手な金額で入れない（単価表にない場合は「要個別見積もり」と記載）
- 合計金額の暗算ミス防止のため、小計の加算は必ず一行ずつ検算する
What ships with it
1 file 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.

mitsumori-web is a skill published in the GitHub repository elefant-coder/skill-hub (0 stars, last pushed 18d ago), licensed MIT. It adds 69 tokens to every session and 591 once invoked, about $0.0003 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.
