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 | $0.00028 | $0.00453 |
| Opus 5.5 | $0.00011 | $0.00181 |
| Sonnet 5.5 | $0.00006 | $0.00091 |
| Haiku 4.5 | $0.00003 | $0.00045 |
Grade A, and why
db-table 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.
What it actually says
DB テーブル追加・変更スキル
ユーザーが「〇〇テーブルを追加して」「〇〇カラムを追加して」と指示したときに適用する。
手順
1. Prisma スキーマ変更
apps/webapp/prisma/schema.prisma を編集:
- テーブル名は
@@map("snake_case_plural")でスネークケース複数形にマッピング - カラム名は
@map("snake_case")でスネークケースにマッピング idは@id @default(cuid())を使用- タイムスタンプは
@db.Timestamptz()を付与 - 日時カラムには
@map("snake_case")を付ける
2. マイグレーション作成
pnpm db:migrate
マイグレーション名の入力を求められたら、変更内容を簡潔に英語で入力する（例: add_jokes_table）。
3. Repository 生成
- Interface (
src/backend/domain/repositories/{name}.repository.ts)- ドメインモデル型のみ使用
- 実装 (
src/backend/infrastructure/repositories/prisma-{name}.repository.ts)- Prisma Client 経由で CRUD
- ORM 型 ↔ ドメインモデル変換を担当
4. Domain Model 生成
src/backend/domain/models/{name}.model.ts:
- Rich Domain Model（ファクトリメソッド
create()+reconstruct()） - バリデーションはモデル自身で行う
ルール
prisma db pushは使用禁止（必ずprisma migrate devを使う）- Repository interface にORM型を出さない
- 変更後に
pnpm verifyを実行
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.

db-table is a skill published in the GitHub repository jujunjun110/product-starter (17 stars, last pushed 4mo ago), licensed MIT. It adds 28 tokens to every session and 453 once invoked, about $0.0001 per session on Opus 5.5. 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.
