Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

fix-error 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 today.

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

エラー修正スキル

ユーザーがエラーメッセージを貼り付けて「直して」と指示したときに適用する。

手順

  1. エラーメッセージを解析 — エラーの種類と発生箇所を特定
  2. 原因を特定 — コードを読んで根本原因を調査
  3. 修正を実施 — アーキテクチャルールに違反しない形で修正
  4. 検証pnpm verify で全チェックがパスすることを確認

よくあるエラーと対処

型エラー(TypeScript)

  • tsc --noEmit で確認
  • 型の不一致を修正。any は使わない

依存方向違反(dependency-cruiser)

  • pnpm depcruise で確認
  • 依存方向: presentation → application → domain ← infrastructure
  • application から infrastructure を直接 import している場合 → Gateway interface 経由に修正
  • presentation/loaders,actions から domain,infrastructure を import している場合 → composition 経由に修正

Prisma エラー

  • スキーマ変更後に pnpm --filter webapp prisma generate を忘れている場合が多い
  • マイグレーションが必要な場合は pnpm db:migrate

lint エラー

  • pnpm lint:fix で自動修正

ルール

  • 修正時もアーキテクチャルール(依存方向、命名規約)を守る
  • 修正後は必ず pnpm verify を実行
  • エラーの根本原因を修正する(場当たり的な回避策は避ける)

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.
