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 | $0.00024 | $0.00301 |
| Opus 5 | $0.00012 | $0.00151 |
| Sonnet 5 | $0.00005 | $0.00060 |
| Haiku 4.5 | $0.00002 | $0.00030 |
Grade A, and why
add-page 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 yesterday.
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
ページ追加スキル
ユーザーが「〇〇ページを作って」と指示したときに適用する。
生成するファイル
-
ページ (
src/app/{path}/page.tsx)- Server Component として作成
- loader 経由でデータを取得
page.tsxにロジックを書かない
-
Loader (
src/backend/presentation/loaders/{name}.loader.ts)- composition から UseCase を取得してデータを返す
- 必要に応じて複数データソースを
Promise.allで並列取得
-
必要に応じて UseCase / Repository 等も追加
- 既存の UseCase で対応できる場合は新規作成不要
ルール
- デフォルトは Server Component。
'use client'は必要な場合のみ - データ取得は必ず loader 経由（page.tsx で直接 DB アクセスしない）
- UI は shadcn/ui + Tailwind CSS で構築
- フォームがある場合は Server Action（
backend/presentation/actions/）を使用
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.

add-page is a skill published in the GitHub repository jujunjun110/product-starter (17 stars, last pushed 2mo ago), licensed MIT. It adds 24 tokens to every session and 301 once invoked, about $0.0001 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 2026-09-03.
